QUESTION 
               You asked whether claimant R~ (Claimant), the surviving domestic partner of the number
                  holder, J~ (NH), is entitled to payment of surviving spouse benefits.
               
               SHORT ANSWER 
               Yes. Claimant and NH entered into a valid domestic partnership in Oregon. Under Hawaii
                  law, this domestic partnership conferred rights permitting Claimant to inherit intestate
                  from NH to the same extent as a surviving spouse. Accordingly, the agency deems Claimant
                  to be the NH’s surviving spouse for purposes of entitlement to surviving spouse benefits.
               
               SUMMARY OF EVIDENCE 
               On February XX, 2008, Claimant and NH became registered domestic partners in the State
                  of Oregon, as evidenced by their filed Declaration of Domestic Partnership. Based
                  on information provided by the H~ D~ Office, the NH and Claimant resided in W~, Hawaii,
                  since October 2011. The NH died in H~, Hawaii on July XX, 2014, according to a Certificate
                  of Death issued by the Hawaii Department of Health.
               
               APPLICABLE LAW 
               Federal Law 
               To be entitled to survivor’s benefits under Title II of the Social Security Act (Act),
                  a claimant must establish that she or he is the widow or widower of an individual
                  who died fully insured.[5] See Social Security Act §§ 202(e),(f), 216(c)(1),(g)(1); 20 C.F.R. § 404.335. Under Section 216(h)
                  of the Act, 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.[6] Social Security Act § 216(h)(1)(A)(i). However, even if the claimant was not married
                  to the insured individual, the agency will deem the claimant to be the insured individual’s
                  widow or widower if, under the laws of the State where the insured individual had
                  a permanent home, the claimant would be able to inherit a surviving spouse’s share
                  of the insured individual’s personal property if he or she died without leaving a
                  will. Social Security Act § 216(h)(1)(A)(ii); 20 C.F.R. § 404.345. Under such circumstances,
                  the agency will treat the couple’s relationship as a marital relationship. See id.
               In addition to establishing that she or he is the insured’s widow or widower under
                  the laws described above, to recover surviving spouse benefits, the claimant must
                  show that she or he meets one of the following conditions: (1) his or her relationship
                  to the insured as wife or husband lasted for at least 9 months immediately before
                  the insured died; (2) his or her relationship to the insured as wife or husband did
                  not last for at least 9 months but another qualifying condition is satisfied; (3)
                  he or she and the insured had a child together; or (4) in the month before marrying
                  the insured, he or she was entitled to or could have been entitled to certain benefits
                  or payments. See Social Security Act §§ 202(e),(f); 20 C.F.R. § 404.335.
               
               Hawaii Law
               In 2011, the Hawaii Legislature amended the Hawaii Revised Statutes to allow individuals
                  to enter into civil unions effective January 1, 2012. Haw. Rev. Stat. ch. 542B.[7] To be eligible, the individuals must (1) not already be a partner in another civil
                  union or a spouse in a marriage; (2) be at least eighteen years old; and (3) not be
                  related by blood to the other partner. Haw. Rev. Stat. § 572B-2; see also § 572B-3 (listing family relationships where a civil union would be void). Partners
                  to a civil union in Hawaii receive the same rights, benefits, protections and responsibilities
                  as spouses that are married under Hawaii law. Haw. Rev. Stat. § 572B-9.
               
               Furthermore, partners to a civil union have “spouse-like” inheritance rights. A partner
                  to a civil union is included in the definition or use of the term “spouse” and “other
                  terms that denote the spousal relationship, as those terms are used throughout the
                  laws of the State.” Haw. Rev. Stat. § 572B-11. Thus, civil union partners inherit
                  the same as spouses. See Haw. Rev. Stat. § 560:2-102 (providing for the inheritance rights of a decedent’s
                  “spouse”).
               
               Hawaii law recognizes non-marital legal unions formed in other jurisdictions and treats
                  them like civil unions entered into in Hawaii as long as the union (1) satisfies civil
                  union eligibility requirements under Hawaii law; (2) was validly formed in another
                  jurisdiction in accordance with its laws; and (3) can be documented. Haw Rev. Stat.
                  § 572B-10.
               
               Oregon Law 
               In 2007, the Oregon State Legislature enacted the Oregon Family Fairness Act, allowing
                  same-sex couples to enter into 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).[8] To enter into a domestic partnership, individuals must file a Declaration of Domestic
                  Partnership that (1) states each person is at least 18 years old and capable of entering
                  into a domestic partnership; (2) states at least one of the individuals resides in
                  Oregon; (3) provides a mailing address; (4) states each individual consents to the
                  jurisdiction of Oregon courts for any proceeding related to the partners’ rights and
                  obligations; and (5) indicates each individual’s name after domestic partnership.
                  Or. Rev. Stat. § 106.325. Both partners must sign and notarize the declaration. Id. Individuals cannot enter into a domestic partnership if either person is married
                  or in another domestic partnership with a different person, or if the parties are
                  related by blood as first cousins or closer. Or. Rev. Stat. § 106.315(1).
               
               ANALYSIS 
               Claimant and NH entered into an Oregon domestic partnership over six years before
                  the NH’s death on July XX, 2014. The relationship therefore exceeded the nine-month
                  duration requirement for surviving spouse benefits. See 20 C.F.R. § 404.335(a)(1); POMS GN 00210.004.
               
               Claimant resided with the NH in Hawaii at the time he died. Accordingly, to determine
                  Claimant’s entitlement to surviving spouse benefits, the agency will look to Hawaii
                  law. If, under the laws of Hawaii, Claimant would be able to inherit intestate from
                  the NH to the same extent as a surviving spouse, then the agency will deem Claimant
                  to be the NH’s widower. See Social Security Act § 216(h)(1)(A)(i); 20 C.F.R. § 404.345.
               
               Under Hawaii law, since January 1, 2012, partners to a civil union receive the same
                  rights as married couples, including the right to inherit to the same extent as a
                  surviving spouse. See Haw. Rev. Stat. § 572B-9; Haw. Rev. Stat. § 572B-11 (providing that a party to a
                  civil union is included in any definition or use of terms that denote a spousal relationship);
                  Haw. Rev. Stat. § 560:2-102 (providing for intestate succession for surviving spouses);
                  see also POMS GN 00210.004 (noting Hawaii civil unions provide for spousal inheritance rights).
               
               Hawaii will recognize a legal union formed in another jurisdiction – and treat it
                  the same as a Hawaii civil union – as long as the relationship (1) satisfies Hawaii’s
                  civil union eligibility requirements; (2) was validly formed in another jurisdiction;
                  and (3) can be documented. Haw. Rev. Stat. § 572B-10. Here, as set forth below, Claimant’s
                  Oregon domestic partnership satisfies the requirements to be recognized under Hawaii
                  law, such that Claimant could inherit to the same extent as a surviving spouse if
                  the NH died intestate.
               
               The Domestic Partnership Satisfied Hawaii’s Civil Union Requirements
               Hawaii’s civil union requirements are included in the requirements to enter into a
                  domestic partnership in Oregon.[9] Therefore, since the Claimant and NH attested to their compliance with Oregon’s requirements
                  when they entered into their domestic partnership,[10] their relationship similarly satisfied Hawaii’s civil union requirements.
               
               The Domestic Partnership Was Validly Formed Under Oregon Law 
               Claimant and NH entered into a domestic partnership in Oregon on February XX, 2008,
                  soon after Oregon’s domestic partnership law became effective. See 2007 Oregon Laws Ch. 99 (H.B. 2007), §§ 1-9. As required under Oregon law, they filed
                  a signed and notarized Declaration of Domestic Partnership, and a County Clerk thereafter
                  signed the form and registered the partnership. See Or. Rev. Stat. § 106.325. Therefore, the couple entered into a valid domestic partnership
                  under Oregon Law.
               
               The Domestic Partnership Was Documented 
               Claimant provided the agency with a certified copy of his Declaration of Domestic
                  Partnership, which is the operative legal document establishing his domestic partner
                  relationship with the NH.[11] Claimant, therefore, has documentation of the domestic partnership.
               
               CONCLUSION 
               Hawaii will recognize a domestic partnership entered into in Oregon as long as the
                  union (1) meets Hawaii’s civil union eligibility requirements; (2) was validly entered
                  into under Oregon laws; and (3) can be documented. Here, the domestic partnership
                  between the NH and Claimant satisfied these requirements. Accordingly, under Hawaii
                  law, Claimant would be entitled to inherit to the same extent as a surviving spouse
                  if NH died intestate. The agency therefore deems Claimant to be the NH’s spouse, entitling
                  him to surviving spouse benefits.
