QUESTION PRESENTED
               You asked whether, under California law, K~(Claimant) is currently married to the
                  number holder (NH), A~, or was married to him for more than 10 years, such that she
                  is entitled to spouse’s or divorced spouse’s benefits on the NH’s account.   
               
               SHORT ANSWER
               No. Claimant remains married to her current spouse, who she married in 2005. The 2012
                  California state court order merely established the existence of her 1973 confidential
                  marriage to the NH as a matter of state record. Claimant has not produced sufficient
                  evidence to overcome the strong presumption that her three subsequent marriages were
                  valid. Even if Claimant’s current marriage ends, because Claimant remarried in 1980,
                  she cannot meet the duration requirement for entitlement to divorced spouse’s benefits
                  on the NH’s account.
               
               BACKGROUND
               Claimant was born on December. A table detailing the relevant chronology is available
                  at Appendix A.
               
               According to Claimant’s November XX, 2005 and April XX, 2006 Applications for Retirement
                  Insurance Benefits (RIB), Claimant married R~ in 1961 and divorced him in 1965 in
                  Las Vegas, Nevada. On January XX, 2014, Claimant supplied the divorce decree, which
                  confirmed that her marriage to R~ was dissolved on February XX, 1965.
               
               Claimant next married and divorced G~. In her initial statements to the agency, Claimant
                  stated that she had married G~ in 1968 and divorced him in 1969. However, according
                  to publically available records from the Church of Latter-Day Saints, Claimant married
                  G~ on August XX, 1967 in Ventura County. At the agency’s request, Claimant provided
                  the Final Judgment of Dissolution from the Superior Court of California, County of
                  Ventura, which showed that her marriage to G~ was dissolved on July XX, 1970.
               
               According to Claimant’s April XX, 2013 declaration, on March XX, 1973, she married
                  the NH in a religious ceremony in Thousand Oaks, California, at the Church of Jesus
                  Christ of Latter Day Saints. Claimant stated that it was her understanding that no
                  license was necessary and that the Church would register the confidential marriage
                  with Ventura County. According to Claimant, the NH petitioned for adoption of Claimant’s
                  three children on February  XX, 1975, allegedly submitting a verified petition confirming
                  that he had married Claimant on March XX, 1973, and asserting that they continued
                  to cohabitate as spouses since their marriage. 
               
               Claimant and the NH lived together until they separated in August 1980, at which time
                  they seem to have severed contact. In her RIB applications, Claimant initially averred
                  that she and the NH had obtained a divorce. However, in her subsequent statements,
                  Claimant confirmed that no formal dissolution of marriage was obtained. 
               
               When contacted telephonically by the agency, the NH reported that he had attempted
                  to obtain a divorce from Claimant, but the Ventura County Clerk told him that because
                  a marriage license was never filed with the county, their marriage was not valid.
                  The agency has contacted the NH, but has been unable to secure a signed statement
                  to date.
               
               Thus, according to the NH and as confirmed by Claimant, the parties proceeded to remarry
                  under the belief that a divorce was unnecessary.
               
               Claimant submitted a marriage certificate showing that she married M~ on October XX,
                  1980 in Clark County, Nevada. Claimant’s original statement to the agency indicated
                  that she married M~ in 1982.
               
               According to the divorce judgment, Claimant and M~ had one biological child together,
                  born on. Claimant divorced M~ on August , 1990, in Ventura County.
               
               Claimant married N~ in Ventura County in 1989 or 1990, and divorced N~ in Los Angeles
                  County in 1990. 
               
               Claimant married W~ in Las Vegas, Nevada in 1998, and divorced W~ on February XX,
                  2001, in Clark County, Nevada (Court Order provided).
               
               Claimant married K2~ on April XX, 2005, in Las Vegas, Nevada (Marriage Certificate
                  provided). According to agency records, Claimant also changed her name a number of
                  times, some of which, but not all, coincided with her marriages. In 1959, Claimant’s
                  record reflects her use of K~ as her original surname. Claimant changed her surname
                  to A2~ in 1966; however, no associated marriage was reported. During the subsequent
                  years, Claimant changed her surname as follows: in 1969 to G~, in 1970 to H~, in 1982
                  to M~, in 1994 to K~, and in 1998 to W~. She does not appear to use the surname K2~.
               
                As detailed below, we have received no documentation indicating that Claimant or
                  K2~ have taken action to secure an annulment or divorce, and they consider themselves
                  married.  Nonetheless, Claimant subsequently filed for auxiliary spouse’s benefits
                  on the NH’s account on the theory that she remained married to the NH since 1973.   
               
               Based on statements provided by both Claimant and the NH, Ventura County apparently
                  had no record of Claimant’s 1973 confidential marriage.  Under California law, the
                  parties could have registered the confidential marriage by filing a declaration at
                  any time. However, Claimant maintains that the NH refused to join in such a declaration. 
                  Therefore, on December XX, 2011, Claimant filed a petition in the Los Angeles County
                  Superior Court to establish the fact and validity of the 1973 marriage. See Cal. Fam. Code § 309; Cal. Health & Safety Code § 103450. In documents submitted to
                  the agency, Claimant and her representative (her attorney for that proceeding) state
                  that the NH was present at the March XX, 2012 hearing, and admitted that the marriage
                  had occurred. A recent statement from K2~ indicates that he was also aware of and
                  present for the court proceedings.
               
               On April XX, 2012, the Court issued an Order Establishing Fact of Marriage, which
                  establishes that Claimant and NH married on March XX, 1973 (Court Order provided),
                  and a Court Order Delayed Certificate of Marriage (Certificate provided). Claimant
                  has provided no evidence that she subsequently registered the court ordered marriage
                  as directed by the court and required by state law.
               
               Claimant sent letters dated October XX, 2012, to the Superior Courts of Los Angeles,
                  Kern, and Ventura Counties—the three counties in which she believed that the NH may
                  have domiciled since 1973— requesting that each clerk search the county records for
                  a divorce between Claimant and the NH, which would have occurred between March 1973
                  and March 1983. All three counties reported that no records were found. Claimant provided
                  a notice from the Deputy Clerk of the Los Angeles County Superior Court dated November
                  XX, 2012. Claimant provided a notice from the Deputy Clerk of the Kern County Superior
                  Court dated December XX, 2012. Claimant provided an undated notice from the Court
                  Services Assistant of the Ventura County Superior Court.
               
               Despite Claimant’s legal actions with respect to her marriage to the NH, she appears
                  to remain married to K2~. Claimant listed K2~ as her spouse when she applied for RIB
                  based on her own primary insurance amount in 2005. According to the Lancaster Field
                  Office, Claimant continues to refer to K2~ as her present spouse in communications
                  with the agency. Claimant and K2~ continue to use the same mailing address for their
                  RIB payments, indicating that they still live together. 
               
               K2~ did not list Claimant as his spouse when he filed for RIB in 2010. However, on
                  January XX, 2014, in response to the agency’s request for additional information,
                  K2~ presented at the Lancaster Field Office and completed a sworn statement declaring
                  that he did not list Claimant as his spouse on his RIB application because, at the
                  time he filed, Claimant was “going through the court process to find out if she was
                  still legally married” to the NH. K2~ further stated that “[his] wife would love to
                  be able to file under [his] Social Security Record[] because she would receive a higher
                  benefit amount. The reason she has not filed yet[] is [that they] do not know if her
                  marriage to [the NH] is valid or if [their] marriage is valid.” Although K2~ claims
                  that the court proceedings began prior to his RIB application in 2010, the agency
                  has only received documents regarding the December 2011 court petition. K2~ does not
                  explain the date discrepancy or indicate whether some other legal proceedings may
                  have preceded the Claimant’s 2011 petition.
               
               The NH married B~ on November XX, 1985, and they remain married today. On February
                  XX, 2012, the NH applied for RIB, attesting that he was presently married to B~ and
                  had no prior marriages that lasted 10 years or more. B~ filed for and has received
                  RIB since January 2002 based on her own primary insurance amount. 
               
               LEGAL STANDARDS
               Federal Law
               The Social Security Act (Act) looks to state law to determine whether a spousal relationship
                  exists. Act § 216(h)(1)(A)(i); see also 20 C.F.R. § 404.345; Program Operations Manual System (POMS) RS 00202.001.A.1 (“A legal spouse must be validly married to the NH under the laws of the State
                  of the NH’s domicile at the time the claimant files an application or during the life
                  of the application.”) If a spousal relationship cannot be established under state
                  law, a person may still be eligible for benefits based upon a “deemed valid marriage
                  . . . if, in good faith, [the claimant] went through a marriage ceremony with the
                  insured that would have resulted in a valid marriage except for a legal impediment.” 20
                  C.F.R. § 404.346; see also POMS RS 00202.001.A.2. To be entitled to benefits as the result of a deemed valid marriage, the purported
                  spouse must be cohabitating with the insured, if living, at the time that he or she
                  applies for spouses benefits. 20 C.F.R. § 404.346.
               
                If the courts in the state of domicile would not find the parties validly married,
                  the applicant may be deemed the spouse of the insured if she could inherit as a spouse
                  under the state laws for intestate distribution of personal property. Act § 216 (h)(1)(A)(ii);
                  20 C.F.R. § 404.345.
               
               A spouse age 62 or older of an insured person who is entitled to old-age or disability
                  benefits is also entitled to benefits if the relationship has lasted at least one
                  year and the applicant is not entitled to an old-age or disability benefit based upon
                  a primary insurance amount that is equal to or larger than the full spouse’s benefit. Act
                  § 202(b); see also 20 C.F.R. § 404.330; POMS RS 00202.001; SSA Handbook § 305. 
               
               In the case of conflicting marriages, most states presume that the most recent marriage
                  is valid. SSA Handbook § 310 (“If all the information and evidence supplied still
                  leaves doubt as to whether your last marriage(s) ended, then your most recent marriage
                  will be presumed the valid one.”). If there is information indicating the applicant’s
                  marriage to the NH may have terminated, the agency requires statements from both parties
                  to establish that the marriage is not terminated. POMS RS 00202.070.B.
               
               A divorced spouse is entitled to spouse’s benefits on the account of an insured person
                  who is entitled to old-age benefits if the divorced spouse was validly married to
                  the insured under state law, was married to the insured for at least 10 years immediately
                  before the divorce became final, is presently unmarried, is age 62 or older, and is
                  not entitled to old-age or disability benefits based upon a primary insurance amount
                  that is equal to or larger than the full spouse’s benefit. Act § 202(b); see also 20 C.F.R. § 404.331, POMS RS 00202.005; SSA Handbook § 311.
               
               California Law
               Here, we apply the laws of California, the state in which the NH is domiciled, in
                  determining the validity and duration of Claimant’s marriage to the NH.
               
               In California, “[a] ceremonial marriage is presumed to be valid.” Cal. Evid. Code
                  § 663. In order to validate a marriage, the marriage “shall be licensed, solemnized,
                  and authenticated, and the authenticated marriage license shall be returned to the
                  county recorder of the county where the marriage license was issued, as provided in
                  this part.” Cal. Fam. Code § 306. However, “[n]oncompliance with this part by a nonparty
                  to the marriage does not invalidate the marriage.” Cal. Fam. Code § 306; see also Estate of D~, 118 Cal. Rptr. 2d 143, 155 (Cal. Ct. App. 2002) (explaining that “a failure by the
                  person solemnizing the marriage to return the certificate of registry would not invalidate
                  the marriage”).  The POMS indicate that, in California, “where at least one of the
                  parties to an invalid [ceremonial] marriage . . . entered into the marriage in good
                  faith believing that it was valid, the spouse had status as a putative spouse and
                  inheritance rights as a spouse so long as such good faith belief continued.” POMS
                  GN 00305.085.B.1. If, after learning of the defect, “the parties undertook within a reasonable
                  time to legalize their marriage, then the status as a spouse continued.” POMS GN 00305.085.B.1.3. 
               
               California law provides for “confidential” marriages which have different licensing
                  and disclosure requirements. At the time of Claimant’s confidential marriage to the
                  NH, California Civil Code section 4213 (previously Section 79) did not require the
                  parties to obtain a license in advance of the marriage ceremony if the couple were
                  not minors, were already living together as husband and wife, and were married by
                  a member of the clergy. California amended its confidential marriage code provision
                  in 1977 to expand the group of persons authorized to solemnize such marriages, and
                  a 1981 revision substantially altered the procedures. See 11 WITSUM Ch. XV, § 48 (2005).
               
                As section 4213 then provided, “[a] certificate of such [confidential] marriage shall
                  be made by the clergyman, delivered to the parties, and recorded upon the records
                  of the church of which the clergyman is a representative. No other record need be
                  made.”  The state permits confidential marriages, a practice dating back to the 1800s,
                  “to shield the parties and their children, if any, from the publicity of a marriage
                  recorded in the ordinary manner, and thereby to encourage unmarried persons who have
                  been living together as man and wife to legalize their relationship.” Encinas v. Lowthian Freight Lines, 69 Cal. App. 2d 156, 163 (Cal. Ct. App. 1945). 
               
               Pursuant to California Family Code section 309, the current confidential marriage
                  provision, “[i]f either party to a marriage denies the marriage, or refuses to join
                  in a declaration of the marriage, the other party may proceed, by action pursuant
                  to section 103450 of the Health and Safety Code, to have the validity of the marriage
                  determined and declared.” California’s Health and Safety Code section 103450, thus,
                  allows a beneficially interested person to file a petition with the clerk of the superior
                  court in and for the county in which the marriage is alleged to have occurred, or
                  the county of residence of the person whose marriage it is sought to establish, for
                  an order to judicially establish the fact of, and the time and place of, a marriage
                  that is not registered or for which a certified copy is not obtainable. Cal. Health
                  & Safety Code § 103450(a).  Upon affirming such a petition, the superior court judge
                  issues an Order Establishing Fact of Marriage and a Court Order Delayed Certificate
                  of Marriage, which must be registered with the California Office of Vital Record. “Court
                  Order Delayed Certificate of Marriage”, California Department of Public Health, January
                  2012, available at http://www.cdph.ca.gov/certlic/birthdeathmar/Documents/CourtOrderDelayed MarriagePAMPHLET-(01-13)-MERGED.pdf (last visited Nov. 7, 2013).  To do so, the petitioner
                  must submit a certified copy of the Order Establishing Fact of Marriage, the completed
                  Court Order Delayed Certificate of Marriage, and pay a $20 fee. Id. Once the request has been received and evaluated, estimated at approximately 6 weeks,
                  the Office of Vital records sends the petitioner a postcard notifying him or her that
                  the request was accepted. Id. Additional time is necessary for processing the registration. Id. 
               “California law provides, with limited exceptions, that an individual can only be
                  married to one person at a time.” Seaton v. Seaton, 133 Cal. Rptr. 3d 50, 52 (Cal. Ct. App. 2011) (citing Cal. Fam. Code § 2201). California
                  Family Code section 2201 provides: “(a) A subsequent marriage contracted by a person
                  during the life of a former husband or wife of the person, with a person other than
                  the former husband or wife, is illegal and void from the beginning, unless: [¶] (1)
                  the former marriage has been dissolved or adjudged a nullity before the date of the
                  subsequent marriage.”
               
                California, like most jurisdictions, employs the presumption that once a marriage
                  has been shown to exist, it is presumed to be legal and valid, even if it is a second
                  marriage. E.g., Vargas v. Superior Court, 88 Cal. Rptr. 281 (Cal. Ct. App. 1970). This presumption is said to be one of the
                  strongest presumptions known to the law.  Marsh v. Marsh, 250 P. 411 (Cal. Ct. App. 1926). Even a bigamist may be estopped from questioning
                  the validity of a second marriage. See 32 Cal. Jur. 3d Family Law § 79 (citing Rediker v. Rediker, 221 P.2d 1 (Cal. 1950) (holding that a person who sought a foreign divorce and remarried
                  was estopped from later asserting the invalidity of the foreign divorce to avoid obligations
                  to the second spouse); In finding that the plaintiff was estopped from asserting the
                  invalidity of a divorce because he had aided and counseled the defendant in getting
                  it so that she would marry him, the court in R~ notes that “To hold otherwise protects
                  neither the welfare nor the morals of society but, on the contrary, such holding is
                  a flagrant invitation to others to attempt to circumvent the law, cohabit in unlawful
                  state and when tired of such situation, apply to the courts for a release from the
                  indicia of the marriage status.” R~, 221 P.2d at 7 (quoting Harlan v. Harlan, 161 P.2d 490 (Cal. Ct. App. 1945)). In re Marriage of R~, 187 Cal. Rptr. 887 (Cal. Ct. App. 1982) (holding that a person who participates in
                  a formal marriage ceremony with a second person knowing that the second person had
                  not obtained a final divorce is estopped from asserting the invalidity of marriage
                  to the second person to avoid spousal support)). POMS GN 00305.175 similarly recognizes that a party may be estopped to deny the validity of the termination
                  of a marriage if she remarried or otherwise accepted or acted in recognition that
                  the termination was valid (e.g., knew of the termination of marriage and allowed it
                  to stand unchallenged for many years). 
               
               The validity of a second marriage arises as soon as the second marriage is proved,
                  and even where there is no proof regarding termination of the first marriage. Luckett v. La Tour, 9 P.2d 886 (Cal. Ct. App. 1932) (holding that “[e]ven without evidence of the divorce
                  proof of the second marriage would raise the presumption that it was valid and the
                  burden of proving the contrary was upon the appellant”). “The basis of the presumption
                  as applied to a subsequent marriage is a policy decision that a person entering into
                  a subsequent marriage will be presumed not to have committed bigamy.” 32 Cal. Jur.
                  3d Family Law § 74 (citing Estate of S~, 507 P.2d 78 (Cal. 1973), and Patillo v. Norris, 135 Cal. Rptr. 210 (Cal. Ct. App. 1976)). The presumption in favor of the second
                  marriage is stronger where there are children born of the later marriage, and increases
                  as time passes. 55 Corpus Juris Secondum Marriage § 55 (collecting cases).  
               
               California’s policy decision to presume the validity of the second marriage has significance
                  for any party seeking to prove the continuation of the first marriage. “The presumption
                  of the validity of the second marriage displaces the presumption of continuance of
                  the first relation.” 32 Cal. Jur. 3d Family Law § 78; see, e.g., M~, 250 P. at 413 (noting that “[i]t has been held time and again by the supreme court
                  of this state that mere proof of a prior marriage and the continued life of both spouses
                  is not sufficient to make a case against a second ceremonial marriage, that there
                  must be a further showing that the first marriage has not been set aside by judicial
                  decree”). “[T]he burden is cast upon the party asserting guilt or immorality to prove
                  the negative—that the first marriage had not ended before the second marriage.” M~, 250 P. at 413 (internal citation omitted); see also Estate of S~, 507 P.2d at 83 (relying on Estate of S~, 201 P.2d 539 (Cal. 1949) and V~, 88 Cal. Rptr. 281). Because of the strength of this presumption, courts have generally
                  required a high degree of proof to overcome it. See In re H~’s Estate, 160 P. 548 (Cal. 1916); Moran v. Superior Court, 100 P.2d 1096 (Cal. Ct. App. 1940). 
               
               A search of the public records in jurisdictions where the insured resided could rebut
                  the presumption that the second marriage was valid. See, e.g., Estate of S~, 201 P.2d at 541 (stating that, “had an annulment [of the first marriage] been secured[,]
                  the existence of such a decree would have been discovered in the search of [such]
                  records”); see also V~, 88 Cal. Rptr. at 283 (citing Cal. Evid. Code §§ 604, 606, 663) (holding that no search
                  need be performed in jurisdictions other than those where the decedent resided or
                  was domiciled); accord Cal. Evid. Code § 605. Other “cogent and compelling” evidence
                  could also rebut the presumption. See V~, 88 Cal. Rptr. at 285 (relying on rebuttal evidence such as decedent’s continued cohabitation
                  with his first wife).
               
               California law also provides that a court may enter an order of dissolution of a marriage
                  retroactively, i.e., “nunc pro tunc,” Nunc pro tunc means “now for then” in Latin. It is a phrase applied to acts allowed to be done
                  after the time when they should have been done, with a retroactive effect. Black’s
                  Law Dictionary 964 (5th ed. 1979). if it determines that by “mistake, negligence,
                  or inadvertence, the judgment has not been signed, filed and entered.” Cal. Fam. Code
                  § 2346(a). The history of nunc pro tunc dissolution of marriages in California is set forth in In re H~ Estate, 182 P.2d 253 (Cal. Dist. Ct. App. 1947). As the H~ court explained, when enacted by the California Legislature in 1935, the purpose
                  of then-Civil Code Section 133 (now Family Code Section 2346), was to “validate otherwise
                  void marriages and thus relieve the parties to such marriages from the stigma and
                  other consequences of bigamous relationships into which they might innocently fall
                  by reason of oversight or neglect to have a final decree entered. Mere entry of the
                  nunc pro tunc judgment acts retroactively to restore them to the status of single persons and at
                  the same time gives them and their later acquired spouses legal married status.” Id. at 553; see also Hurst v. Hurst, 39 Cal. Rptr. 162, (Cal. Dist. Ct. App. 1964) (“entry of a final decree of divorce
                  nunc pro tunc usually has as its purpose the validation of a marriage which would otherwise be
                  bigamous”). Section 2346(b) provides that the court may act on its own motion or upon
                  the motion of either party to the proceeding. Upon entry of judgment, the parties
                  have the same rights that they would have had if the dissolution of marriage had been
                  entered on the date when it originally could have been entered. Cal. Fam. Code. §
                  2346(d); see also POMS PR 06205.006 (specifically PR 03-015) (discussing prior California law, and explaining rationale
                  for nunc pro tunc entry of judgment).
               
               Although unpublished, the case of In re Marriage of L~, 2006 WL 697905 (Cal. Dist. Ct. App. March 20, 2006), is helpful for analyzing how
                  a California court would view Claimant’s current marital status.  Based on the advice
                  of the clerk of the court that she would automatically be divorced six months after
                  she served her husband with process, the appellant in L~ did not complete the necessary steps to obtain a final judgment of dissolution of
                  marriage to her first husband. Id. at *1. Upon realizing the oversight, appellant obtained a dissolution, but she had already
                  remarried. Id. When appellant and her second husband began having marital trouble, he sought to annul
                  the marriage on the ground that appellant had been married to her first husband at
                  the time of her second marriage. Id. at *2. The appellant then sought an ex parte application to have the dissolution of marriage entered nunc pro tunc to a date before her second marriage, which the court granted. Id. A court subsequently granted the second husband’s request to nullify the marriage,
                  explicitly disregarding the nunc pro tunc dissolution. Id. at *2.  In reversing the judgment of nullity, the Court of Appeals found that “[a]s established
                  by long-standing case law, a nunc pro tunc dissolution judgment should be considered by a court in evaluating an annulment petition,
                  even when the nunc pro tunc judgment was obtained after the filing of an annulment action by a subsequent spouse.” Id. at *5 (collecting cases). 
               
               DISCUSSION
               Here, Claimant has reached age 62, rendering her potentially entitled to spouse’s
                  or divorced spouse’s benefits; however, she has not sustained her burden of proof
                  for the remaining elements of either benefit on the NH’s account. Under California
                  law, Claimant cannot show that she is presently married to the NH. Even if the Claimant
                  has a good faith belief that she is presently married to the NH, she is not cohabitating
                  with him, so she cannot meet the regulatory requirement for a deemed marriage. See
                  20 C.F.R. § 404.346.
               
               See 20 C.F.R. §§ 404.330, 404.346. Alternatively, Claimant cannot show either that
                  she was married to the NH for 10 years or is presently unmarried; thus, she cannot
                  meet the requirement for divorced spouse benefits. See 20 C.F.R. § 404.331. 
               
               Claimant apparently maintains that the 2012 Court Order Delayed Certificate of Marriage
                  means that her 1973 confidential marriage to the NH continues to exist. Based on the
                  factual background provided and the law as it existed in 1973, the California court
                  appears to have properly found that the NH and Claimant entered into a confidential
                  marriage as Claimant contends. As the POMS reflects, the agency has previously issued
                  opinions pertaining to the validity of confidential marriages in California. See POMS PR 05405.006 California. In PR 86-006, issued on February 13, 1986, the agency held that a couple
                  who exchanged vows in a ceremony presided over by an acquaintance who claimed to be
                  a self-ordained minister could meet the requirements to establish a confidential marriage
                  in accordance with California Civil Code section 4213 even though they had not obtained
                  a marriage license, were not issued a marriage certificate, and for whom no civil
                  record of marriage existed. As PR 86-006 found, as long as there is credible evidence
                  that the parties held themselves out as married prior to the confidential marriage
                  ceremony, “a confidential marriage can be made out despite the dubious credentials
                  of the officiating minister or the failure of this clergyman to issue a marriage certificate.” As
                  PR 86-006 further noted, “Section 4200 of the Civil Code provides that noncompliance
                  with procedural requirements such as these ‘by others than a party to a marriage does
                  not invalidate it.’”  Similarly, PR 82-004, issued on March 19, 1982, found that a
                  confidential marriage solemnized in a private ceremony performed under section 4213
                  was neither void nor voidable despite the parties having allegedly misrepresented
                  that they were living together as husband and wife prior to the marriage. Here, Claimant’s
                  1970 surname change to B~ indicates that the parties were likely cohabitating and
                  presenting themselves as married prior to their alleged confidential marriage ceremony
                  in 1973. 
               
               PR 87-013, issued on August 14, 1987, concluded that although the participants in
                  a confidential marriage ceremony had misrepresented that they had both obtained the
                  age of consent prior to entering a confidential marriage pursuant to Civil Code Section
                  4213, voluntary cohabitation after attaining the age of consent negated any defects
                  in the marriage ceremony. Therefore, the agency held that because the marriage was
                  not legally terminated prior to the number holder’s death, the claimant (and not the
                  number holder’s subsequent wife) was his widow under California law and, consequently,
                  for purposes of Social Security benefits. This case is, however, distinguishable from
                  the instant matter because the number holder in PR 87-013 could have obtained a divorce
                  and in not doing so, knowingly entered into a bigamist marriage that was void or voidable
                  (based on the unclear timing of the separation and subsequent marriage and birth of
                  an additional offspring, the second wife could have also been aware that she was entering
                  into a bigamist marriage). Further, here, unlike in Opinion B, Claimant has not sufficiently
                  proven that the NH has not sought to terminate the marriage or alternatively that
                  a court would not enter a nunc pro tunc divorce as discussed in the text.
               
               However, Claimant misunderstands the legal significance of that court order. 
               Claimant maintains that her 1973 marriage continues to exist because neither party
                  sought dissolution of this marriage. Claimant provided notices from November and December
                  2012 from the three counties in which the NH was believed to have domiciled since
                  1973, all stating that no records were found for a divorce between Claimant and the
                  NH occurring between March 1973 and March 1983. The NH does not claim to have sought
                  a divorce; rather, he claims that he relied on advice that a divorce was not necessary. Claimant’s
                  theory that the marriage continues fails for two reasons: First, while the court order
                  establishes the fact of the 1973 marriage, Claimant has failed to show that she properly
                  registered the court ordered marriage. If the marriage is not registered with the
                  state, neither she nor the NH will be afforded an opportunity to initiate an action
                  to dissolve the marriage (e.g., a nunc pro tunc divorce). Notably, a search of divorce records prior to the 2012 court order (as
                  Claimant provided here) could not provide information about whether the NH sought
                  or obtained a dissolutation after that order.
               
               Second, Claimant has not supplied any evidence to refute the strong presumption that
                  her subsequent marriages were valid and she would be estopped (prevented) from doing
                  so under California law based on her conduct in remarrying three more times. See 32 Cal. Jur. 3d Family Law § 79 (collecting cases); POMS GN
                     
                     00305.175. Any argument that Claimant would make regarding putative spouse status would similarly
                  not refute the strong presumption that her subsequent marriages were valid, most notably
                  her current marriage to K2~.
               
               Further, Claimant admitted being separated from the NH for over 30 years, and having
                  entered into and ending several marriages before she sought the Court Order Delayed
                  Certificate of Marriage. She, thus, obtained a legal benefit from not having the 1973
                  confidential marriage registered – ease of remarriage – and could not credibly claim
                  lack of knowledge with respect to divorce proceedings. Because Claimant divorced several
                  times before marrying the NH, she was aware and knowledgeable of divorce proceedings. California
                  courts will look to the equities and entirety of circumstances in making determinations
                  on the existence or continuation of marriages. See Estate of S~, 201 P.2d at 540 (“In any particular case, the question must be determined, like any
                  other question of fact, upon a consideration of the attending facts and circumstances,
                  and such inferences as fairly and reasonably flow therefrom.”). Were Claimant to assert
                  any current spousal rights under California law in relation to the NH, a California
                  court would likely conclude that her marriage to the NH ended in 1980 when she married
                  M! and could order a formal nunc pro tunc dissolution of Claimant’s marriage to the NH. See Cal. Fam. Code § 2346. 
               
               In sum, a California court is unlikely to consider Claimant and the NH currently married
                  and would not find her eligible to inherit from the NH’s intestate estate. Claimant
                  and the NH provided consistent statements regarding their separation and each has
                  subsequently remarried. Claimant’s subsequent marriages are presumptively valid under
                  California law and Claimant has not submitted any contrary evidence; rather, she has
                  submitted valid marriage and divorce records for all of her other marriages. Her 1980
                  marriage to M~ (which lasted 9 years and produced biological offspring) served to
                  effectively terminate her marriage to the NH and her 2005 marriage to K2~ continues
                  to date. Similarly, the NH is still married to the spouse he married in 1985 and,
                  as set forth above, the law provides a strong presumption that parties acting in good
                  faith are not bigamists. 
               
               CONCLUSION
               Claimant bears the burden of establishing all eligibility requirements. As such, because
                  Claimant failed to rebut the presumption that her marriage to the insured ended at
                  the latest when she married M~ in October 1980 and that her 2005 marriage to K2~ remains
                  valid, she is not entitled to spouse’s or divorced spouse’s benefits on the NH’s record. See 20 C.F.R. §§ 404.330, 404.331, 404.345, 404.346.
