You have requested an opinion on whether DNA testing of genetic material provided
                  by the deceased wage earner's parents is sufficient to establish paternity under Illinois
                  law so that Leticia N. S~ (Leticia) can be considered the wage earner's child for
                  child's insurance benefit purposes. See 42 U.S.C. § 416(h)(2)(A); 20 C.F.R. § 404.355(b)(2). For the reasons stated herein,
                  we advise that you undertake additional development to eliminate any brother of the
                  wage earner, Robert R. O~ (Robert), as possible father of Leticia. If Robert had no
                  brothers, or if he had brothers but the possibility that one of them fathered Leticia
                  can be eliminated, we believe that, based on the DNA test results and the additional
                  information you provided, an Illinois court would find Robert was Leticia's father.
               
               C~
               In 1987, Robert began dating Lorie B. S~, a.k.a. Lorie C~ (Lorie). On July 11, 1990,
                  Leticia was born. Leticia's birth certificate does not identify a father. The couple
                  dated until 1991. On October 9, 2001, Robert died without marrying Lorie. At the time
                  of his death, Robert was domiciled in Illinois.
               
               On October 21, 2001, Lorie filed an application for surviving child's benefits on
                  Leticia's behalf. In April of 2002, Robert's parents, Lorie, and Leticia were tested
                  by Genetica DNA Laboratories, Inc. The resulting DNA analysis did not exclude Robert's
                  parents as paternal grandparents of Leticia. The analyst, Elizabeth P~, M.D., Ph.D.,
                  certified that the estimated probability of grandparentage by Robert's parents, as
                  compared to an untested, unrelated couple of the North American Hispanic population,
                  was 99.95%.
               
               On May 1, 2002, Robert's mother, Beatrice O~ (Beatrice) wrote a letter stating that
                  she and her husband recognized Leticia as Robert's daughter and that they sent Leticia
                  clothing every month.
               
               ANALYSIS
               If the wage earner is deceased, the Social Security Administration (SSA) applies the
                  intestacy laws for the state where the deceased wage earner had a permanent home at
                  the time of death. 20 C.F.R. § 404.355(b)(1). Here, Robert was domiciled in Illinois
                  at the time of his death. Therefore, Leticia can be eligible for surviving child's
                  benefits on Robert's account only if she could inherit Robert's property as his child
                  under Illinois law governing intestate succession. 42 U.S.C. § 416(h)(2)(A). Illinois
                  intestacy law requires illegitimate children who seek to inherit from their deceased
                  fathers to provide authenticated copies of proper court orders of paternity. 755 ILCS
                  5/2-2(h). However, under Social Security regulations, the child is not required to
                  obtain an adjudication of paternity. 20 C.F.R. § 404.355(b)(2). Rather, the SSA adjudicator
                  determines paternity using the state's standard. Under Illinois law, Leticia would
                  have to prove paternity by “clear and convincing evidence.” 755 ILCS 5/2-2(h).
               
               The Illinois Parentage Act of 1984 makes DNA testing of the alleged father admissible
                  to establish paternity. 750 ILCS 45/11. If the test shows that the alleged father
                  is not excluded and that the combined paternity index is at least 500 to 1, the court
                  presumes paternity. 750 ILCS 45/11(f)(4). This presumption may be rebutted by clear
                  and convincing evidence. Id. Absent a presumption of paternity, Illinois law requires clear and convincing evidence
                  of paternity. 755 ILCS 5/2-2(h).
               
               However, the Illinois Parentage Act of 1984 does not address use of grandparent DNA
                  to establish the presumption of paternity. Although such grandparent DNA test results
                  may constitute evidence Illinois courts would consider when determining paternity,
                  they do not, standing alone, establish that Leticia is Robert's natural child. In
                  the Matter of the Estate of Lukas, 508 N.E.2d 368, 372 (1st Dist. 1987) (at hearing, expert testimony was presented
                  regarding use of paternal grandmother's blood test results to establish her decedent
                  son was child's father). Although probative because of the high probability percentage,
                  the results demonstrate only that Leticia is biologically linked to the alleged paternal
                  grandparents' family. They do not rule out the possibility that another male member
                  of Robert's family, such as a brother, could be the natural father. See Memorandum from OGC Region V to SSA-MOS, Does Posthumous Genetic Testing Based on
                  the DNA of the Deceased Numberholder's Relatives Establish Paternity Under Michigan
                  State Law?, Jeffrey W~, page 5, (May 25, 2000) (explaining that DNA testing of paternal
                  relatives only demonstrates child's biological link to putative paternal family, but
                  it does not rule out possibility that one of deceased's male relatives fathered child).
               
               Here, the claim is bolstered somewhat by Robert and Lorie's four-year relationship
                  and Beatrice's statement that she and her husband recognized Robert as Leticia's father.
                  However, there is also evidence that detracts from that conclusion, such as the lack
                  of Robert's identification as father on Leticia's birth certificate. Moreover, no
                  evidence was presented that Robert ever acknowledged paternity or contributed to the
                  child's support. Taking such factors into consideration, in order to meet the “clear and convincing” legal standard to prove paternity, it is advisable that additional evidence be collected,
                  such as statements from Robert's brother(s), if any, and Lorie, ruling out such brother(s)
                  as Leticia's father.
               
               You also asked, if paternity was established, what would be the appropriate date of
                  entitlement. For purposes of entitlement to surviving child's benefits, Leticia would
                  be considered Robert's child for inheritance purposes as of the date of his death.
                  See Warren-Boynton State Bank v. Wallbaum, 528 N.E.2d 640, 643 (Ill. 1988) (stating that “heirs” in the technical sense of the word are always determined at the time of the testator's
                  death).
               
               CONCLUSION
               Under Illinois law, it is unlikely the “clear and convincing” evidence standard proving paternity has been met. Therefore, it is recommended that
                  additional documentation be obtained to rule out any likelihood that a brother of
                  Robert fathered Leticia. If additional evidence eliminates the possibility that a
                  brother is Leticia's father, it is likely that an Illinois court would then determine
                  that Robert was Leticia's father. Therefore, it is our opinion that Leticia can be
                  considered Robert's child for the purpose of receiving surviving child's benefits
                  on Robert's account if adequate non-genetic evidence, as described above, is obtained.
