QUESTION PRESENTED
               D~ (Claimant) filed an application for widow’s insurance benefits on the record of
                  the deceased number holder (NH) C~. The Claimant alleges a common-law marriage to
                  the NH beginning in April 2009 and ending with the NH’s death on December XX, 2021,
                  in the District of Columbia. The couple separated in February 2019. You asked whether
                  a valid common-law marriage existed between the NH and the Claimant under District
                  of Columbia law such that the Claimant is the NH’s widow under Title II of the Social
                  Security Act (Act).
               
               ANSWER
               We believe District of Columbia courts would find that the Claimant has proven by
                  a preponderance of the evidence that she was in a valid common-law marriage with the
                  NH under District of Columbia law from April 2009 until the NH’s death on December
                  XX, 2021. Once a valid common-law marriage exists, it may be terminated only by death
                  or divorce. Thus, the couple’s separation in 2019 did not terminate their valid common-law
                  marriage. Accordingly, we believe there is support for the agency to find that the
                  Claimant is the NH’s widow for purposes of determining her entitlement to widow’s
                  insurance benefits on the NH’s record.
               
               BACKGROUND
               The NH died on December XX, 2021, domiciled in the District of Columbia.[1] On October XX, 2022, the Claimant filed an application for widow’s insurance benefits
                  as the NH’s widow. You stated that she alleged a common-law marriage with the NH from
                  April 2009 until the NH’s death on December XX, 2021. They lived together in the District
                  of Columbia until they separated in February 2019, at which time the Claimant moved
                  to Pennsylvania and the NH stayed in the District of Columbia.
               
               In support of her common-law marriage claim, the Claimant completed the Form SSA-754
                  Statement of Marital Relationship in November 2022 and provided a few documents. She
                  was living in Pennsylvania. She reported that she and the NH began living together
                  as spouses in April 2009 in the District of Columbia. She stated that they lived together
                  continuously in the District of Columbia as spouses for almost ten years from April
                  2009 until February 2019 when they separated. When they began living together, they
                  told each other that they loved one another, they understood they would be together
                  forever, and the NH always introduced her as his wife. She reported that they did
                  a lot of things that married people did such as filing joint tax returns for the years
                  2014 through 2018. The Claimant provided IRS documents confirming that for the 2016
                  and 2017 tax periods, the NH and the Claimant filed tax returns jointly as a married
                  couple. Documents from their landlord in 2009 indicate that the Claimant and the NH
                  had been living together at a property in the District of Columbia for fifteen years.
                  The Claimant had a prior spouse who died in August 2004.
               
               The Claimant identified three of her relatives and one of the NH’s relatives who knew
                  of their relationship but stated that his sister may not want to answer questions
                  because they were not speaking to her. She also reported that their separation in
                  2019 was due to his family. Two of the Claimant’s relatives provided marital statements
                  to the agency supporting the Claimant’s common-law marriage with the NH. None of the
                  NH’s relatives provided statements.[2]
               G~, the Claimant’s sister, completed the Form SSA-753 Statement Regarding Marriage.
                  She described herself as the NH’s sister-in-law and stated she had known him for 28-29
                  years. She would visit the couple often. The NH attended all family events. To her
                  knowledge, the NH and the Claimant were generally known as a married couple and she
                  considered them to be a married couple. She reported that the Claimant cooked, cleaned,
                  washed clothes, and shopped for the entire household and took care of the NH, who
                  had cerebral palsy. She reported that she heard the NH and the Claimant refer to each
                  other as spouses and that this was always how they described their relationship. She
                  believed that they maintained a home and lived together continuously as a married
                  couple in the District of Columbia from 2009 to 2020 when they separated. She stated
                  that even after they separated, the Claimant continued to do things for the NH.
               
               E~, another one of the Claimant’s sisters, completed the Form SSA-753 Statement Regarding
                  Marriage. She described herself as the NH’s sister-in-law and reported knowing the
                  NH for 24 years. To her knowledge, the NH and the Claimant were generally known as
                  a married couple and she considered them to be a married couple because of how long
                  they were together, the fact that the NH called her his sister-in-law, and the fact
                  that they lived together at her house and her mother’s house. She heard the NH and
                  the Claimant refer to one another as spouses whenever they were together and stated
                  that he always called her his sister-in-law. She believed that the Claimant and the
                  NH maintained a home and lived together continuously as a married couple in the District
                  of Columbia from 2009 until 2019.
               
               ANALYSIS
               A. Federal Law: Entitlement to Widow(er)’s Insurance Benefits as a Widow(er)[3]
               Under Title II of the Act, a claimant may be entitled to widow(er)’s insurance benefits
                  on a deceased insured individual’s record if, among other requirements, the claimant
                  is the widow(er) of the insured individual and their marriage relationship lasted
                  at least nine months before the insured individual died.[4] See 42 U.S.C. §§ 402(e), (f), 416(a)(2), (c), (g); 20 C.F.R. § 404.335.
               
               The agency will find a claimant to be an insured individual’s widow(er) if the courts
                  of the State in which the insured individual was domiciled at the time of death would
                  find that the claimant and the insured individual were validly married at the time
                  the insured individual died, or if, under application of that State’s intestate succession
                  laws, the claimant would be able to inherit a spouse’s share of the insured individual’s
                  personal property. See 42 U.S.C. § 416(h)(1)(A); 20 C.F.R. §§ 404.344, 404.345. It
                  is our understanding that the NH was domiciled in the District of Columbia when the
                  NH died on December XX, 2021. Therefore, we look to the District of Columbia law to
                  determine if the Claimant is the NH’s widow.
               
               B. State Law: Validly Married under District of Columbia Law at the Time of the NH’s
                     Death
               1. District of Columbia Law and the Claimant’s Common-Law Marriage to the
                     NH
               a. Elements of a Common-Law Marriage
               “The District of Columbia has long recognized common-law marriages.” Coates v. Watts,
                  622 A.2d 25, 27 (D.C. 1993). Under District of Columbia law, the elements of a common-law
                  marriage are:
               
               1. an express mutual agreement, which must be in words of the present tense, to be
                  permanent partners with the same degree of commitment as the spouses in a ceremonial
                  marriage,
               
               2. followed by cohabitation. In re Estate of Jenkins, 290 A.3d 524, 528 (D.C. 2023);
                  Gill v. Nostrand, 206 A.3d 869, 875 (D.C. 2019).
               
               The agreement to be married “must be consummated by cohabitation if it is to result
                  in a marriage.” U.S. Fidelity & Guaranty Co. v. Britton, 269 F.2d 249, 251 (D.C. Cir.
                  1959). However, “living together, by itself, is not a common-law marriage.” Cerovic
                  v. Stojkov, 134 A.3d 766, 776 (D.C. 2016). While there is no set formula required
                  for the agreement, the exchange of words must unambiguously indicate that an agreement
                  was being entered into to become spouses as of the time of the mutual consent. Coates
                  v. Watts, 622 A.2d 25, 27 (D.C. 1993). The agreement must be in the present-tense;
                  an agreement to be married in the future is insufficient.[5] Gill, 206 A.3d at 875; Coates, 622 A.2d at 27. Further, the agreement must be mutual,
                  which means that if only one party to the purported common-law marriage believes they
                  are married, but the other party does not, a common-law marriage cannot be established.
                  Gill, 206 A.3d at 881.
               
               b. Burden of Proof: Preponderance of the Evidence
               The burden is on the proponent to prove the essential elements of a common-law marriage
                  by a preponderance of the evidence.[6] Cerovic, 134 A.3d at 774-775; Coates, 622 A.2d at 27. The preponderance of the evidence
                  standard means that the court must determine who has the most competent evidence.
                  In re E.D.R., 772 A.2d 1156, 1160 (D.C. 2001). It means “evidence which is of greater
                  weight and more convincing than the evidence presented in opposition to it; that is
                  evidence which is as a whole shows that the fact sought to be proved is more probable
                  than not.” Id. (quoting Black’s Law Dictionary). “Whether a common-law marriage exists
                  is largely a factual determination.” Mesa v. U.S., 875 A.2d 79, 83 (D.C. 2005). In
                  terms of the type of evidence offered to meet this burden, the parties may provide
                  direct evidence of their common-law marriage in the form of the parties’ testimony
                  and documents, such as property deeds and tax records. Mesa, 875 A.2d at 83. Testimony
                  by the parties is the best evidence of the present-tense express mutual agreement
                  to be married.[7] Gill, 206 A.3d at 875. However, the mutual agreement “may be inferred from the character
                  and duration of cohabitation, or from other circumstantial evidence such as testimony
                  by relatives and acquaintances as to the general reputation regarding the parties’
                  relationship.” Gill, 206 A.3d at 875; Mesa, 875 A.2d at 83. Such an inference may
                  then be rebutted by direct evidence that there was in fact no present agreement to
                  be married. Mesa, 875 A.2d at 83.
               
               2. Application of the Elements of the Common-Law Marriage to the Claim
               a. Mutual Agreement to be Married
               As stated, District of Columbia case law requires an express mutual agreement to be
                  permanent partners with the same degree of commitment as the spouses in a ceremonial
                  marriage. In re Estate of Jenkins, 290 A.3d at 528; Gill, 206 A.3d at 875. Here, there
                  is no information indicating that the parties had an agreement to marry in the future
                  or that the agreement to be married was not mutual. We believe District of Columbia
                  courts would find direct evidence of a present-tense mutual agreement to be married
                  in the form of the Claimant’s statements and the IRS documents showing that they presented
                  themselves as married on their tax returns. The Claimant reported on the SSA Form-754
                  that she and the NH began living together as spouses in April 2009 in the District
                  of Columbia and they lived together continuously for almost ten years from April 2009
                  until February 2019 when they separated. When they began living together, they told
                  each other that they loved one another, they understood they would be together forever,
                  and the NH always introduced her as his wife. The Claimant reported that they did
                  a lot of things that married people did such as filing joint tax returns for the years
                  2014 through 2018. The Claimant provided IRS documents confirming that for the 2016
                  and 2017 tax periods, the NH and the Claimant filed tax returns jointly as married.
                  Documents from their landlord in 2009 indicate that the Claimant and the NH had been
                  living together at a property in the District of Columbia for fifteen years even prior
                  to 2009.
               
               Additionally, their ten years (plus) of cohabitation and reputation as being married,
                  as attested to by the Claimant’s sisters, supports a mutual agreement to be married.
                  Both sisters reported that the NH and the Claimant were generally known as a married
                  couple, they believed them to be a married couple, and they heard them refer to one
                  another as spouses. They also reported that the NH and the Claimant lived together
                  continuously as a married couple from 2009 until 2019. Sister G~ reported that the
                  Claimant cared for the NH, who had cerebral palsy, and that she did all of the chores
                  for the household.
               
               Given these statements and documents, we believe District of Columbia courts would
                  find a preponderance of the evidence supports this required element of a mutual agreement
                  to be married for a common-law marriage.
               
               b. Cohabitation
               As noted, District of Columbia case law requires that the couple live together following
                  their mutual agreement to be married. In re Estate of Jenkins, 290 A.3d at 528; Gill,
                  206 A.3d at 875. Here, the Claimant’s statements, the sisters’ statements, and the
                  landlord’s records corroborate their years of cohabitation in the District of Columbia
                  from at least April 2009 to February 2019. We believe District of Columbia courts
                  would find a preponderance of the evidence supports this required element of cohabitation
                  for a common-law marriage.
               
               c. Summary: Valid Common-Law Marriage Terminated by the NH’s Death
               In summary, this is not a claim involving conflicting evidence or deficient evidence
                  as to a particular required element. We believe District of Columbia courts would
                  find that uncontroverted statements from the Claimant and her two sisters, the longevity
                  of their relationship, the IRS documents showing they presented their marital status
                  as married filing jointly, and the landlord documents confirming cohabitation in 2009
                  constitutes competent evidence establishing that it was more probable than not that
                  the NH and the Claimant were common-law married under the District of Columbia law.
               
               Finally, we note that the Claimant and the NH separated in 2019 and lived apart until
                  the NH’s death in 2021. Once established, “a common law marriage may be legally terminated
                  only by divorce or death of a spouse.” Cerovic, 134 A.3d at 781 (citing Hoage v. Murch
                  Bros. Constr. Co., 50 F.2d 983, 984 (D.C. 1931)); see also Lee v. Lee, 201 A.2d 873,
                  875 (D.C. 1964) (declaring an attempted ceremonial marriage void because an earlier
                  common-law marriage had not been dissolved). Thus, similar to other States that recognize
                  common-law marriage, there is no common-law divorce under the laws of the District
                  of Columbia. See Phillips v. The Dow Chemical Co., 186 S.W.3d 121, 127 (Tex. App.
                  – Houston [1st Dist.] 2005, no pet.) (“Texas recognizes common-law marriage but does
                  not recognize common-law divorce or annulment.”); see also Estate of Claveria v. Claveria,
                  615 S.W.2d 164, 167 (Tex. 1981) (common-law marriage, like a ceremonial marriage,
                  can terminate only by death or divorce). Therefore, although they separated in 2019,
                  in the absence of any evidence of a divorce, the Claimant’s common-law marriage with
                  the NH did not terminate until the NH’s death in 2021.
               
               CONCLUSION 
               We believe District of Columbia courts would find that the Claimant has proven by
                  a preponderance of the evidence that she was in a valid common-law marriage with the
                  NH under the District of Columbia law from April 2009 until the NH’s death on December
                  XX, 2021. Once a valid common-law marriage exists, it may be terminated only by death
                  or divorce. Thus, the couple’s separation in 2019 did not terminate their valid common-law
                  marriage. Accordingly, we believe there is support for the agency to find that the
                  Claimant is the NH’s widow for purposes of determining her entitlement to widow’s
                  insurance benefits on the NH’s record.
