Question Presented
               Should the agency consider parties to a Washington state domestic partnership to be
                  spouses for purposes of survivor’s benefits where the insured died while domiciled
                  in Oregon?
               
               Short Answer
               Yes. The agency could consider the claimant to be the number holder’s (NH) spouse
                  based on the Washington domestic partnership. Here, where the domestic partnership
                  laws of Oregon and Washington are substantially similar, and both provide for spousal
                  inheritance rights, Oregon policy would not prevent recognition of this validly formed
                  Washington domestic partnership. Thus, because the claimant can inherit as the NH’s
                  spouse under Oregon law, the agency should consider the claimant and the NH as married
                  for benefits purposes when the NH passed away while domiciled in Oregon.
               
               Background
               On June XX, 2015, K~ (claimant) and B~ (NH) filed for and were issued a certificate
                  of state registered domestic partnership by the State of Washington. There is no evidence
                  that their domestic partnership was not validly formed. Thereafter, the couple moved
                  to Oregon together, but never married or registered as an Oregon domestic partnership.
                  They continued to reside together in Oregon until the NH’s death in December 2018.
                  The claimant now seeks survivor’s benefits.
               
               Applicable Law
               Federal Law
               An individual must establish a marital relationship with the NH in order to be entitled
                  to widow’s or widower’s benefits. 42 U.S.C. § 402(e)-(f); 20 C.F.R. § 404.335. Where
                  there is a non-marital legal relationship rather than a marriage, the agency determines
                  whether the non-marital legal relationship qualifies as a marital relationship using
                  the intestacy laws of the state of the NH’s domicile when he or she died. 42 U.S.C.
                  § 416(h)(1)(A)(i); 20 C.F.R. § 404.345. If, under state law, a claimant could inherit
                  a spouse’s share of the NH’s personal property if the NH died without leaving a will,
                  the agency treats the couple’s non-marital legal relationship as a marital relationship
                  for purposes of determining entitlement to benefits. 20 C.F.R. § 404.345. In this
                  case, the NH was domiciled in Oregon at the time of death; therefore, Oregon state
                  law governs.
               
               Oregon Law
               Oregon began recognizing domestic partnerships in 2008. Or. Rev. Stat. § 106.300 et
                  seq. Domestic partnerships are allowed except when (1) either party has another partner
                  or spouse living at the time of the domestic partnership; (2) the parties are first
                  cousins or any nearer kin to each other; or (3) either party is incapable of consenting
                  to the contract for want of age or understanding. Id. § 106.315. Oregon law grants
                  couples registered as domestic partners the same survivor benefits as married couples.
                  Id. § 106.340(1). A surviving spouse is entitled to a share of the deceased spouse’s
                  estate when the spouse dies intestate. Or. Rev. Stat. §§ 112.025, 112.035. Oregon
                  registered domestic partnerships thus qualify as marital relationships for SSA benefits
                  purposes. POMS GN 00210.004D.
               There is no explicit provision in Oregon law either recognizing or rejecting out-of-state
                  registered domestic partnerships. However, as a general principle of Oregon law, “a
                  marriage which is recognized as valid in the state where it was performed will be
                  recognized in Oregon.” Garrett v. Chapman, 449 P. 2d 856, 858 (1969). There is a potential
                  exception to that rule “where the policy of this state dictates a different result
                  than would be reached by the state where the marriage was performed.” Id. Thus, when
                  considering the validity of marriages formed in other states, the question is whether
                  any Oregon policy would prevent recognition of the marriage.
               
               Washington Law
               Beginning in July 2007, Washington state began permitting couples to enter into state
                  registered domestic partnerships where certain requirements are met. Wash. Rev. Code
                  §§ 26.60.010, 26.60.030. Similar to Oregon’s domestic partnership law, a Washington
                  state domestic partnership is only permitted where the individuals are not already
                  married to or in a state registered domestic partnership with someone else; are of
                  age and capable of consenting; and are not closely related. Id. The parties of a state-registered
                  domestic partnership are treated the same as married spouses and have the same inheritance
                  rights under intestacy law. Id. §§ 11.04.015(1); 26.60.015. Thus, the agency will
                  deem Washington state-registered domestic partners married for the purposes of Title
                  II benefits. See POMS GN 00210.004D.
               Analysis
               While the claimant and the NH neither married nor entered into a domestic partnership
                  in Oregon, Oregon courts would likely recognize a Washington state domestic partnership
                  as a marriage for the purposes of applying intestate laws. Oregon case law is replete
                  with challenges to the marital status of decedents in intestate proceedings, including
                  challenges involving out-of-state marriages. In such cases, Oregon courts have undertaken
                  an analysis of whether there was valid marriage under the law of the state where the
                  marriage occurred and, if so, whether Oregon policy would dictate a different result
                  See, e.g., Garrett, 449 P.2d at 856 (considering whether an Idaho marriage was valid
                  under the laws of Idaho and Montana and whether Oregon policy would dictate a contrary
                  finding).
               
               Accordingly, an Oregon court would likely recognize the claimant and NH’s out-of-state
                  domestic partnership. As Washington’s domestic partnership law is substantially similar
                  to Oregon’s domestic partnership law, it does not appear that Oregon policy would
                  prevent recognition of this validly formed Washington domestic partnership. Compare
                  Wash. Rev. Code §§ 26.60.015, 26.60.030, with Or. Rev. Stat. §§ 106.315 & 106.340.
                  Because Oregon would likely recognize this domestic partnership for inheritance purposes,
                  the agency may treat the couple’s relationship as a marital relationship for purposes
                  of determining entitlement to benefits.
               
               Conclusion
               The agency could deem the claimant and NH as married based on their Washington-registered
                  domestic partnership because, we believe that the Oregon courts would recognize such
                  a relationship allows for intestate inheritance rights as a spouse. Accordingly, you
                  could find the claimant is entitled to survivor’s benefits on the NH’s record.
