QUESTION PRESENTED
               You asked whether C~ (claimant) is entitled to widower’s benefits and a lump-sum death
                  payment (LSDP) on the record of the deceased number holder (NH), J~, based on a California
                  domestic partnership. The NH was domiciled in Indiana when he died.
               
               SHORT ANSWER
               Yes. We believe that the Indiana courts would recognize a California domestic partnership
                  as a relationship conveying the same inheritance rights as a “spouse.” Therefore,
                  the agency could deem the couple as married for purposes of determining the claimant’s
                  entitlement to benefits under Title II of the Social Security Act (Act)
               
               SUMMARY OF EVIDENCE
               The claimant and the NH entered into a domestic partnership in California on November
                  XX, 2002. They lived in California until approximately June 2013, after which they
                  moved to Indiana. The NH was domiciled in Indiana when he died on March XX, 2015.
                  The claimant sought payment of surviving spouse benefits and a LDSP shortly thereafter.
               
               APPLICABLE LAW
               
               To be entitled to survivor’s benefits under Title II of the Act, a claimant must,
                  among other things[1] , establish that she or he is the widow or widower of an individual who died fully
                  insured. See 42 U.S.C. § 402(e),(f), 416(c)(1),(g)(1); 20 C.F.R. § 404.335. To be entitled to
                  the LSDP under Title II of the Act, a claimant must establish that she or he is the
                  widow or widower of an individual who died fully or currently insured, and was living
                  in the same household as the insured at the time of his or her death. See 42 U.S.C. §§ 402(i), 416(c); 20 C.F.R. § 404.390. The agency will find a claimant
                  to be the widow or widower of an insured individual if the courts of the State in
                  which the insured individual resided at the time of his or her death would find that
                  the claimant was validly married to the insured individual when the death occurred.
                  42 U.S.C. § 416(h)(1)(A)(i).
               
               In addition, the agency uses the term “NMLR” to describe a variety of legal relationships
                  for two individuals who are not considered married, but are provided with some or
                  all of the rights that could be associated with a marriage. POMS GN 00210.004. The claimant and the number holder had an NMLR by virtue of registering a domestic
                  partnership in California. Id. The agency will consider a claimant to be a NH’s spouse for benefit purposes when
                  the state of the NH’s domicile would allow the claimant to inherit a spouse’s share
                  of the NH’s personal property should the NH die without leaving a will. 42 U.S.C §
                  416(h)(1)(A)(ii); 20 C.F.R. § 404.345.
               
               
               California law allows two adults of the same sex to register a domestic partnership
                  with the Secretary of State. Cal. Family Code § 297(a)-(b). Registered domestic partners
                  have “the same rights, protections, and benefits . . . as are granted to and imposed
                  upon spouses.” Cal. Family Code § 297.5(a). “A surviving registered domestic partner,
                  following the death of the other partner, shall have the same rights, protections,
                  and benefits . . . as are granted to and imposed on a widow or a widower.” Cal. Family
                  Code § 297.5(c). Thus, a domestic partner inherits a spousal share when the other
                  partner dies without a will. Cal. Probate Code § 6401 (intestate share of surviving
                  spouse); POMS GN 00210.004(D).
               
               
               Indiana does not have a domestic partnership or civil union statute. POMS GN 00210.004(D). The Indiana Code once provided that “[a] marriage between persons of the same
                  gender is void in Indiana even if the marriage is lawful in the place where it is
                  solemnized.” Ind. Code § 31-11-1-1(b). However, this provision was held unconstitutional
                  and Indiana has permitted same-sex marriage since October 2014. See Baskin v. Bogan, 12 F. Supp. 3d 1144, 1162 (S.D. Ind. 2014), aff’d, 766 F.3d 648 (7th Cir. 2014), cert.
                     denied, 135 S. Ct. 316 (2014).
               
               ANALYSIS
               As stated above, the agency will consider a claimant to be a NH’s spouse for benefit
                  purposes when the courts of the state of the NH’s domicile would allow the claimant
                  to inherit a spouse’s share of the NH’s personal property should the NH die without
                  leaving a will. 42 U.S.C § 416(h)(1)(A)(ii); 20 C.F.R. § 404.345. Here, since the
                  NH was domiciled in Indiana at the time of his death, we look to the laws of Indiana
                  to determine the claimant’s relationship as the NH’s widower. And since the claimant
                  and the NH entered into a domestic partnership in California, it is necessary to determine
                  whether Indiana would allow the claimant to inherit as the NH’s spouse based on their
                  California domestic partnership.
               
               Based on our review of Indiana and California law, we believe it is likely that Indiana
                  would recognize the inheritance rights of domestic partners conferred by California’s
                  domestic partnership law, which includes the right to inherit a spousal share when
                  a person dies intestate. See Cal. Family Code § 297.5(c); Cal. Probate Code § 6401. The Court of Appeals of Indiana,
                  in a case involving the termination of a California registered domestic partnership
                  (RDP), affirmed the trial court’s recognition of the California RDP on comity grounds.
                  Gardenour v. Bondelie, 60 N.E.3d 1109, 1117 (Ind. Ct. App. 2016), transfer
                     denied[2] , 83 N.E.3d 1218 (Ind. 2017) (citing Mason v. Mason, 775 N.E.2d 706, 709 (Ind. Ct. App. 2002)). While the Gardenour court concerned the parental rights and obligations of registered domestic partners
                  under Cal. Family Code § 297.5(d), the court applied its reasoning generally to all
                  of the rights and obligations set forth in Cal. Family Code § 297.5. Gardenour, 60 N.E.3d at 1116-1117. Thus, the reasoning in Gardenour is readily applicable to a domestic partner’s right to inherit a spousal share under
                  Cal. Family Code § 297.5(c).
               
               The appellate court in Gardenour found no error in the trial court’s determination that the “couple’s RDP was the equivalent
                  of marriage.” Id. at 1117; see also id. at 1118 (“California law makes clear a RDP is identical to marriage”). In so holding,
                  the court rejected as “outdated” the claim that “recognition of a same-sex marriage
                  is contrary to Indiana public policy,” given recent federal jurisprudence regarding
                  same-sex marriage. Id. at 1117-18 (citing Obergefell v.
                     Hodges , 135 S. Ct. 2584, 2608 (2015); Baskin , 766 F.3d at 657). Significantly, the appellate court noted that Ind. Code § 31-11-1-1(b)[3] , which stated a same-sex marriage is void in Indiana even if lawful in the state
                  where it is celebrated, was struck down as unconstitutional. Gardenour, 60 N.E.3d at 1118. The appellate court also reasoned that a refusal to “recognize
                  California RDPs as the equivalent of marriage” could “allow individuals to escape
                  the obligations California imposes upon domestic partners.” Id.
               
               In the instant case, we believe that Indiana courts would likely find, consistent
                  with Gardenour, that the claimant’s California RDP was the equivalent of marriage and that it would
                  recognize the RDP as a spousal relationship under the principle of comity. The Gardenour court explicitly held that recognizing same-sex marriage was not against Indiana
                  public policy.
                     Id. at 1117-18. Thus, we believe that Indiana would give effect to the California domestic
                  partnership and allow the claimant to inherit a spousal share.
               
               CONCLUSION
               The claimant and the NH had a valid California domestic partnership which gave the
                  claimant the same rights as a widower under California law. Given the appellate court’s
                  holding in Gardenour, we believe the courts of Indiana likely would recognize the claimant’s California
                  domestic partnership and give effect to the spousal inheritance rights afforded by
                  California law to registered domestic partners. Thus we believe the agency could find
                  Claimant to be the NH’s spouse for purposes of determining the claimant’s entitlement
                  to benefits under Title II of the Act..
