QUESTION
               You asked whether a parent-child relationship exists between Claimant, J~, and the
                  Number Holder (NH), D~, for purposes of establishing Claimant’s entitlement to child’s
                  insurance benefits on NH’s account?[1]
               SHORT ANSWER
               Yes. Claimant is entitled to child’s insurance benefits on NH’s account because a
                  parent-child relationship existed under Hawaii law. NH received Claimant into her
                  home and openly held Claimant out as her child.

               LEGAL STANDARDS
               Federal Law
               Under the Social Security Act (Act), every unmarried minor child of an insured individual
                  who is entitled to old-age or disability insurance benefits is entitled to child’s
                  insurance benefits. Social Security Act § 202(d)(1); 42 U.S.C. § 402(d)(1). To receive
                  child’s insurance benefits, however, the applicant must qualify as the insured individual’s
                  “child,” as defined by section 216(e), and be dependent on the insured individual
                  at the time she filed her application. See id.; 20 C.F.R. § 404.350.
               
               In determining whether a claimant qualifies as the child of the insured individual,
                  the Commissioner applies the law governing the devolution of intestate personal property
                  by the courts of the State in which such insured individual was domiciled at the time
                  of application. Social Security Act § 216(h)(2)(A), 42 U.S.C. § 416(h)(2)(A); 20 C.F.R.
                  § 404.355(a)(1). An applicant who satisfies the requirements of section 216(h)(2)(A)
                  of the Act is also deemed dependent upon the insured individual. 20 C.F.R. § 404.361(a)
                  (“If you are the insured’s natural child, as defined in § 404.355, you are considered
                  dependent upon him or her”);[2] Social Security Ruling (SSR) 77-2c (“where state intestacy law provides that a child
                  may take personal property from a father’s estate, it may reasonably be thought that
                  the child will more likely be dependent during the parent’s life...”).
               
               NH was domiciled in Hawaii at the time Claimant filed her application for benefits.
                  Accordingly, Hawaii intestacy law determines Claimant’s relationship with NH, and
                  thus, her entitlement to child’s insurance benefits.
               
               Hawaii Law 
               Hawaii’s Uniform Probate Code (UPC) provides that children may inherit intestate from
                  their parents, regardless of the parents’ marital status. See Haw. Rev. Stat. § 560:2-114.
                  The UPC also provides that the parent and child relationship may be established under
                  Hawaii’s Uniform Parentage Act (UPA) (Hawaii Revised Statutes, chapter 584). Id.
               
               Pursuant to Hawaii’s UPA, a man is presumed to be the natural father[3] of a child if he “receives the minor child into his home and openly holds out the
                  child as his natural child.” Haw. Rev. Stat. § 584-4(a)(4). The UPA extends this presumption
                  to determining the existence of a mother and child relationship. See Haw. Rev. Stat.
                  § 584-21 (“Any interested party may bring an action to determine the existence or
                  nonexistence of a mother and child relationship. Insofar as practicable, the provisions
                  of this chapter applicable to the father and child relationship shall apply.”); see
                  also Child Support Enforcement Agency v. Doe, 125 P. 3d 461, 471 (Haw. 2005) (by enacting
                  section 584-21, “the legislature has ensured that mothers will be subject to the same
                  enforcement procedures and statutory privileges applied to fathers”).
               
               Public Policy
               In Doe v. Doe, the Hawaii Supreme Court held that the “fundamental purpose” of chapter
                  584 is to “protect the rights and ensure the obligations of parents of children born
                  out of wedlock.” Doe v. Doe, 52 P. 3d 255, 261-62 (Haw. 2002) (internal citation omitted).
                  Thus, the Court explained that “the UPA and, by extension, chapter 584 are largely
                  concerned with establishing a means by which to identify the person (usually the father)
                  against whom these rights may be asserted. In short, it is to ensure that every child, to the extent possible, has an identifiable legal
                     father.” Id. (internal citation omitted) (emphasis added). The Court specifically identified the
                  right to intestate succession as one which chapter 584 intended to provide and determined
                  that the purpose of the UPA is to establish a second legal parent to whom the child
                  may turn for inheritance and support. Id.
               “Holding Out”
               In Inoue v. Inoue, the Hawaii Intermediate Court of Appeals applied section 584-4(a)(4)
                  to determine that a wife was estopped from challenging her husband’s status as the
                  child’s presumed father, even though he was not the biological father. 185 P. 3d 834,
                  842 (Haw. Ct. App. 2008). In that case, the presumed father attended prenatal appointments
                  with the mother, assumed primary child care responsibilities after the mother returned
                  to work, lived with the child from the time of birth, participated in the child’s
                  medical care, established an education account for the child, and held the child out
                  to his family as his own. Id. at 836-37.[4] Based on these facts, the Court concluded that the presumed father “held out” the
                  child as his own, as defined in section 584-4(a)(4). Id. at 842.
               
               Here, NH’s relationship with Claimant is supported by different facts than in Inoue.
                  The Inoue court was concerned with presumed parenthood only to the extent that it
                  strengthened the argument in favor of estoppel, and concluded without analysis that
                  there was evidence of “holding out.” Id. at 842. Thus, Inoue should not be interpreted
                  as establishing the minimum showing for presumed parenthood under section 584-4(a)(4).
                  We are not aware of any Hawaii case in which a court has evaluated what threshold
                  degree of evidence would constitute “openly hold[ing] out the child as [a] natural
                  child” for purposes of presumed parenthood.
               
               However, in California, another state that has adopted the UPA, courts have articulated
                  several factors guiding a determination of presumed parentage based on “holding out.”
                  California’s “holding out” provision and public policy mirror that of Hawaii.[5] Therefore, it is reasonable for us to believe that a Hawaii court would look to California
                  case law for guidance.
               
               In Charisma R., the California Court of Appeal found a presumption of parentage even
                  though the petitioner had only lived with and shared in the child’s care for about
                  three months. Id. at 366-67, 374. The Court found petitioner to be the presumed mother because she
                  was present at the child’s birth, gave the child a hyphenated last name that included
                  her name, and she held herself out as the child’s parent in public announcements.
                  Id.
               Similarly, in S.Y. v. S.B., 201 Cal. App. 4th 1023 (Cal. Ct. App. 2011), the California
                  Court of Appeal upheld the finding of presumed parentage of S.Y., where S.Y. encouraged
                  S.B. to adopt a child with the understanding they would raise the child together;
                  S.Y. voluntarily accepted the rights and obligations of parenthood after the child
                  was born; and no other person claimed to be the child’s second parent. Id. at 1037.
                  Additionally, in E.C. v. J.V., 202 Cal. App. 4th 1076 (Cal. Ct. App. 2012), the California
                  Court of Appeal stressed that, in determining presumed parentage, the State looks
                  at the presumed parent’s commitment to the child’s well-being, as opposed to the presumed
                  parent’s relationship with the biological mother. Id. at 1085.
               
               ANALYSIS
               NH and T~ were married in Canada in July 2006, and remarried in Hawaii in December
                  2013.[6] NH was present at Claimant’s birth, NH shares a surname with Claimant, and NH reported
                  providing emotional support to Claimant since her birth. For instance, NH only began
                  contributing to Claimant’s financial support in 2013. NH listed Claimant as her dependent
                  on her federal tax return for tax year 2013. Furthermore, in 2013, NH began attending
                  Claimant’s parent-teacher conferences and began participating in decisions regarding
                  Claimant’s education and medical care.
               
               Of even greater significance, NH began living with Claimant in October 2013. Therefore,
                  a Hawaii court would likely find that NH “received” Claimant into her home, and “openly
                  held” Claimant out as her child.
               
               Finally, finding NH to be Claimant’s presumed parent is consistent with Hawaii’s public
                  policy. The facts do not indicate that any other individual has taken an active role
                  as Claimant’s second parent. Therefore, Hawaii public policy favors a determination
                  that a parent-child relationship exists between Claimant and NH, as this result ensures
                  that Claimant has the benefit of two parents committed to her welfare. See Doe, 52
                  P. 3d at 261-62.
               
               CONCLUSION
               Under Hawaii law, NH is Claimant’s natural parent and Claimant could inherit intestate
                  from her. As the NH’s natural child, Claimant is deemed dependent on her. Claimant
                  is therefore entitled to child’s insurance benefits on NH’s account under section
                  216(h)(2) of the Act.
