QUESTION PRESENTED
               Issue: Whether D~ W~ (the claimant) is the widow of D~ B~, the deceased number holder
                  (NH), for purposes of the entitlement to widow’s benefits under title II of the Social
                  Security Act (Act). The claimant presented evidence of a marriage ceremony in California
                  prior to the State’s legal recognition of same-sex marriages. The claimant also presented
                  an Oregon Public Employee Benefit Board (PEBB) Affidavit of Domestic Partnership document.
                  You asked if the agency could find the claimant and the NH were legally married in
                  the California ceremony. If not, could the agency find the couple had a common law
                  marriage in California or Oregon? If no marriage can be found, could the agency deem
                  the couple as married based on their Oregon PEBB Affidavit of Domestic Partnership?[1]
               
               BRIEF ANSWER
               No the claimant is not the NH’s widow based on the marriage ceremony held in California
                  prior to the State’s legal recognition of same-sex marriages. In addition, neither
                  California nor Washington permit common law marriage, so the claimant cannot be considered
                  the NH’s widow on that basis. Finally, we believe the courts of Oregon would find
                  that claimant cannot inherit as NH’s widower under Oregon law based on the Oregon
                  PEBB Affidavit of Domestic Partnership document. Accordingly, we believe the agency
                  would be justified in finding claimant is not NH’s widow or deemed widow under title
                  II and therefore is not entitled to widow’s benefits on NH’s earnings record.
               
               SUMMARY OF FACTS
               In May 2001, before California law recognized same-sex marriages, the claimant alleges
                  that she and the NH participated in a ceremonial marriage officiated by Reverend R~
                  G~, a minister of the United Churches of Religious Science in Santa Rosa, Sonoma County,
                  California. The claimant provided a certificate of marriage with the date of the ceremony,
                  which she had notarized in Sonoma County, California on November X, 2014. The claimant
                  also provided an Oregon PEBB Affidavit of Domestic Partnership document signed on
                  November XX 2005.
               
               In July 2010, the NH died in Oregon. Her death certificate lists Oregon as her place
                  of domicile, and describes her marital status as never married. The claimant then
                  applied for surviving spouse benefits in Oregon. The claimant stated that her marriage
                  was not legally recognized in California. She also said that she and the NH planned
                  to register “with the state as domestic partners,” but did not do so because her daughter,
                  and then the NH, became sick and both died.
               
               DISCUSSION
               I. Applicable Law 
               A. Federal Statute and Regulation 
               A claimant may be entitled to widow’s insurance benefits if she is the widow of an
                  individual who died fully insured and she and the insured were married for at least
                  nine months immediately prior to the insured’s death.[2] Act § 202(e)(1); 20 C.F.R.
                  § 404.335(a); Program Operations Manual System (POMS) RS 00207.001A.1.b.1. A claimant can establish that she is the widow of an insured individual if the
                  courts of the State where the insured was domiciled when she died would find that
                  the claimant and insured were validly married. If the claimant was not validly married,
                  we must examine if the claimant has the same status as a widow with respect to taking
                  the insured individual’s personal property through State intestacy laws. Act § 216(h)(1)(A);
                  20 C.F.R. §§ 404.335(a), 404.345; POMS GN 00305.001A.2.a; POMS RS 00207.001A.1.a.1.
               
               Thus, if there is no valid marriage, but the claimant alleges a non-marital legal
                  relationship (NMLR), such as a domestic partnership or civil union, as the basis for
                  entitlement, the agency may deem the claimant and NH married if: (1) the NMLR is valid
                  in the State where it was established; and (2) the State of the NH’s domicile recognizes
                  the NMLR as equivalent to a marriage, or because under State intestacy law, the parties
                  to the NMLR can inherit a spouse’s share of the of each other’s personal property,
                  should one party die. Act § 216(h)(1)(A); 20 C.F.R. § 404.345; cf. POMS GN 00210.004A; POMS GN 00305.005 (determining marital status).
               
               B. Oregon Law
               In May 2014, the United States District Court for the District of Oregon declared
                  unconstitutional Oregon’s previous ban on in-state same-sex marriages and non-recognition
                  of out-of-state same-sex marriages. Geiger v.
                     Kitzhaber, 994 F. Supp. 2d 1128 (D. Or. 2014). Thus, as of the date of the court’s order, Oregon
                  began issuing same-sex marriage licenses and recognizing out-of-state same-sex marriages.[3]
               
               In 2007, the Oregon State Legislature enacted the Oregon Family Fairness Act, allowing
                  same-sex couples to enter into registered domestic partnerships effective February
                  4, 2008. See 2007 Oregon Laws Ch. 99 (H.B. 2007), §§ 1-9 (codified at Or. Rev. Stat. §§ 106.300-106.340).
                  These domestic partnerships “extend benefits, protections and responsibilities to
                  committed same-sex partners and their children that are comparable to those provided
                  to married individuals and their children by the laws of this state.” Or. Rev. Stat.
                  § 106.305(5); see also Or. Rev. Stat. § 106.340. As a result, Oregon domestic partnerships convey spousal
                  inheritance rights. Or. Rev. Stat. § 106.340; see also POMS GN 00210.004.D. Thus, if an Oregon domestic partnership meets the criteria in Or. Rev. Stat. §
                  106.325, the agency can find the registered domestic partnership qualifies as marital
                  relationships for SSA benefits purposes. POMS GN 00210.004D.
               To enter into a registered domestic partnership under Oregon law, individuals must
                  file a Declaration of Domestic Partnership on which each individual shall: (1) state
                  that she or he is at least 18 years old and capable of entering into a domestic partnership;
                  (2) state whether the individual resides in Oregon; (3) provide a mailing address;
                  (4) state that she or he consents to the jurisdiction of Oregon courts for any proceeding
                  related to the partners’ rights and obligations; and (5) indicate the individual’s
                  name after domestic partnership. Or. Rev. Stat. § 106.325. Both partners must sign
                  and notarize the declaration. Id.
               
               C. California
               Historically, same-sex marriage first became legal in California on June 16, 2008,
                  when the California Supreme Court held that a State law barring same-sex marriages
                  was contrary to the State Constitution. See In re Marriage Cases, 43 Cal. 4th 757 (Cal. 2008). However, same-sex marriages were
                  again barred beginning November 5, 2008, after the passage of Proposition 8, a State
                  constitutional amendment. See Strauss v. Horton, 46 Cal. 4th 364, 397-98 (Cal. 2009). On August 4, 2010, the United States District
                  Court for the Northern District of California held that Proposition 8 was unconstitutional.
                  See Perry v.
                     Schwarzenegger, 704 F. Supp.2d 921, 1004 (N.D. Cal. 2010). The United States Court of Appeals for
                  the Ninth Circuit imposed a stay pending appeal, and later affirmed the district court’s
                  decision. See Perry v. Brown, 671 F.3d 1052, 1096 (9th Cir. 2012); Perry v. Schwarzenegger, 2010 WL 3212786 (9th Cir. Aug. 16, 2010). On June 26, 2013, the United States Court
                  of Appeals for the Ninth Circuit lifted its stay. See Perry v. Brown, 725 F.3d 968 (9th Cir. 2013).
               
               California also has various requirements that must be met before a marriage is valid
                  under State law. Cal. Fam. Code §§ 300 et seq. In part, the parties must obtain a
                  marriage license from a county clerk, consent and solemnize the marriage as provided
                  by law, and register the license with the country recorder.[4] Cal. Fam. Code §§ 300(a)-(b).
                  A marriage license issued by a county clerk does not become a marriage certificate
                  until it is registered with the county recorder. Id. at § 300(b).
               
               II. Analysis
               A. Oregon Would not Recognize an Invalid California Marriage
                     
               When considering whether two individuals were spouses for the entitlement to survivor
                  benefits, the agency looks to the laws of the State where the insured individual was
                  domiciled when he or she died. Because the NH was domiciled in Oregon at the time
                  of her death, we apply Oregon law to determine if she and the claimant were spouses.
                  20 C.F.R. § 404.335(a) (referencing 20 C.F.R. § 404.345).
               
               Oregon recognizes any marriage that is valid in the State it was entered into. Garret,
                  449 P.2d at 858. The claimant and the NH participated in a ceremonial marriage in
                  California in 2001, seven years before same-sex marriage first became legal in California.
                  See In re Marriage Cases, 53 Cal. 4th 757 (Cal. 2008). On June 26, 2015, the United States
                  Supreme Court held that all same-sex couples may exercise the fundamental right to
                  marry under the United States Constitution. See
                     Obergefell
                     v. Hodges, 576 U.S. ---, 135 S. Ct. 2584, 2604-05 (2015). The Court held State laws invalid
                  to the extent they exclude same-sex couples from civil marriage on the same terms
                  and conditions as opposite-sex couples. Id., 135 S. Ct. at 2605. Pursuant to Harper v.
                     Va.
                     Dept of
                     Taxation, 509 U.S. 86, 94-98 (1993), the agency should give Obergefell full retroactive effect in all cases still open on direct review and as to all events,
                  regardless of whether such events predate or postdate Obergefell. As a result, the agency considers state-law same-sex-marriage bans, whether based
                  on state constitutional or statutory provisions or on case law, void and ineffective.
                  See POMS GN 00210.002A (stating the agency will recognize a valid same-sex marriage as of the date of the
                  marriage, including during periods when the number holder’s state of domicile did
                  not recognize same-sex marriages).
               
               Therefore, while we cannot consider a state’s ban on same-sex marriage as invalidating
                  a marriage, we still must consider whether a marriage that occurred prior to the date
                  same-sex marriage became legal in California otherwise satisfies the criteria for
                  a valid California marriage, and thus could be recognized by Oregon.
               
               In California, a marriage is valid only if the parties obtain a marriage license from
                  a county clerk, consent and solemnize the marriage as provided by law, and register
                  the license with the county recorder. Cal. Fam. Code §§ 300(a)-(b). A marriage license
                  issued by a county clerk does not become a marriage certificate until it is registered
                  with the county recorder. Id. at § 300(b). Here, the claimant and the NH consented
                  and had a ceremony in Santa Rosa, California; received a document that purports to
                  be a “marriage certificate” (herein after “souvenir certificate”) from the officiant
                  of their ceremony (Reverend R~ G~), and later notarized the souvenir certificate in
                  Sonoma County, California.[5] As Santa Rosa is located in Sonoma County, there must
                  be evidence that a marriage license was obtained from a Sonoma county clerk and registered
                  with the county recorder, at the time of their marriage. Although the souvenir certificate
                  was notarized in Sonoma County, California, on November X, 2014, there is no evidence
                  that a license was obtained from a county clerk or registered.[6] Thus, the marriage
                  is not valid under California law and therefore the courts of Oregon would not recognize
                  it as valid under Oregon law.
               
               B. Oregon Public Employee Benefit Board Affidavit of Domestic Partnership
                     
               Because the claimant and NH did not enter into a valid marriage, we must examine whether
                  the Oregon PEBB Affidavit of Domestic Partnership, signed by the Claimant and the
                  NH, established a registered domestic partnership under Oregon law for basis of entitlement
                  to social security benefits. An Oregon domestic partnership that meets the criteria
                  in Or. Rev. Stat. § 106.325 qualifies as equivalent to a marital relationships under
                  Oregon law and thus for SSA benefits purposes. POMS GN 00210.004D
               To enter into a domestic partnership under Or. Rev. Stat. § 106.325,[7] individuals
                  must file a Declaration of Domestic Partnership on which each individual shall:
               
               a) state that she or he is at least 18 years old and capable of entering into a domestic
                  partnership;
               
               b) state whether the individual resides in Oregon;
               c) provide a mailing address;
               d) state that she or he consents to the jurisdiction of Oregon courts for any proceeding
                  related to the partners’ rights and obligations;
               
               e) indicate the individual’s name after domestic partnership;
               f) sign the form with a declaration that representations made on the form are true,
                  correct and contain no material omissions of fact to the best knowledge and belief
                  of the individual; and
               
               g) have a notary public acknowledge the individual’s signature.
               Here, the Oregon PEBB domestic partnership document provided by the claimant does
                  not comply with all of the criteria for a Declaration of Domestic Partnership required
                  by Or. Rev. Stat. § 106.325. In particular, it does not appear to be on the requisite
                  form required by the Oregon Health Authority pursuant to Or. Rev. Stat. § 106.320.
                  Instead, it is on an Oregon PEBB form.[8]
               
               Or. Rev. Stat. §106.325(1), and (2), a document of Domestic Partnership must be filed
                  with a county clerk and registered. Once registered, the county clerk will return
                  a copy of the registered form and a Certificate of Registered Domestic Partnership
                  to the partners. The document claimant provided does not appear to have been filed
                  or registered with a county clerk. In addition, the requirements in Or. Rev. Stat.
                  §106.325(3) and (4,) contemplate a formal dissolution of the domestic partnership,
                  with the consent of the court. The document the claimant supplied the agency merely
                  requires a statement of termination of the domestic partnership with “payroll” or
                  their “personal representative.” Finally, the signatures are not notarized, as required
                  by Or. Rev. Stat. § 106.325(5)(g). Thus, although claimant and NH had a domestic partnership
                  for PEBB purposes, it does not meet the criteria of a registered domestic partnership
                  under Oregon domestic partnership law at Or. Rev. Stat. §106.325. Therefore, the claimant
                  cannot inherit as NH’s spouse under Oregon and thus SSA find a deemed marriage for
                  purposes widow’s benefits.
               
               CONCLUSION
               The claimant is not the NH’s widow based on the marriage ceremony held in California
                  prior to the State’s legal recognition of same-sex marriages. In addition, neither
                  California nor Washington permit common law marriage, so the claimant cannot be considered
                  the NH’s widow, based on a same-sex common law marriage. Further, we believe the courts
                  of Oregon would find that claimant cannot inherit as NH’s widower under Oregon law
                  based on the Oregon PEBB Domestic Partnership document as it is not equivalent to
                  a registered domestic partnership under Oregon domestic partnership law at Or. Rev.
                  Stat. §106.325. Thus, the agency cannot find a deemed marriage based on the PEBB Domestic
                  Partnership. Accordingly, we believe the agency is justified in finding that claimant
                  is not NH’s widower or deemed widower under Title II and therefore Claimant is not
                  entitled to WIB on NH’s earnings record.

               [1] You did not ask whether claimant could be deemed the widow of the NH based on
                  their Oregon PEBB Affidavit of Domestic Partnership document. However, we will also

               [2] In addition to establishing that she is the widower of the insured, the claimant
                  must establish he meets the other criteria for entitlement to widower’s benefits.
                  See 20 C.F.R. § 404.335. You have not asked, and we have not analyzed, whether the
                  claimant meets these other requirements.

                  NH entered into a common law marriage in California.
               
               [5] Pursuant to POMS GN 00301.050 Evaluating the Validity of Documents and Records,
                  souvenir certificates may “[l]ack of a state or county seal or certification” and
                  “are not acceptable as preferred evidence of… marriage.”
               
               [6] As previously explained, infra, California did not permit same-sex marriage at
                  this time. However, the couple could have entered into a California domestic partnership.
                  Beginning January 2000, California permitted any two same-sex individuals to enter
                  a registered domestic partnership if (1) neither person had an ongoing marriage or
                  domestic partnership with someone else; (2) the individuals were not related by blood;
                  (3) both individuals were at least 18 years of age; and (4) both individuals were
                  capable of consenting to the domestic partnership. Cal. Fam. Code § 297(b); see POMS
                  GN 00210.004(D)(5). Registered domestic partners in California have the same rights, protections,
                  benefits, responsibilities, obligations, and duties “as are granted to and imposed
                  upon spouses.” Cal. Fam. Code § 297.5(a). An individual in a registered domestic partnership
                  has a right to inherit intestate from the other partner the same as a surviving spouse.
                  Cal. Fam. Code § 297.5(c). California’s domestic partnership requirements and benefits,
                  which are comprehensive, are substantially similar to Oregon’s. Compare Or. Rev. Stat.
                  §§ 106.315 & 106.340, and Cal Fam. Code § 297.5. Therefore, Oregon would recognize
                  a validly formed California domestic partnership for inheritance purposes.
               
               [7] In addition to these criteria, individuals are precluded from entering a domestic
                  partnership when: (1) either party had another partner or spouse living at the time
                  of the domestic partnership; (2) the parties were first cousins or any nearer kin
                  to each other; or (3) either party was incapable of consenting to the contract for
                  want of age or understanding. Or. Rev. Stat. §106.315. Here, it appears that the claimant
                  and the NH were not precluded from entering a domestic partnership for any of these
                  reasons.
               
               [8] The website for the Oregon PEBB (which contracts for and administers health benefits
                  for eligible state employees), contemplates that a registered domestic partnership
                  under State law differs from one “by affidavit.” According to the PEBB website: Our
                  benefit program accommodates two types of domestic partnership: by affidavit and by
                  registered certificate.
               
               1. Domestic partnership by affidavit is established between two individuals of same
                  or opposite sex when they attest on a PEBB affidavit to the relationship as described
                  in our Summary Plan Description.
               
               2. Domestic partnership by registered certificate is established between two individuals
                  of the same sex by Oregon Revised Statute.
               
               https://www.oregon.gov/oha/pebb/Benefits/domestic-partners.pdf(last visited on March 31, 2020). Thus it appears that a domestic partnership for
                  purposes of Oregon PEBB is different We have found no case law stating that an Oregon
                  PEBB domestic partnership is equivalent to a domestic partnership formed pursuant
                  to Or. Rev. Stat. § 106.325. With respect to the criteria in from a domestic partnership
                  under the Oregon domestic relationship law at Or. Rev. Stat. § 106.325.
