You have asked for advice on whether a valid marriage still exists between the claimant,
                  Tomasa R~, and the number holder, Amado R~ ("NH"); whether the New York Family Court
                  had jurisdiction to declare their subsequent Cuban divorce void; and thus whether
                  Tomasa R~ is the widow of Amado R~. As we understand the facts of this case, Tomasa
                  R~ contends that she remained the legal wife of Amado R~ until he died because the
                  Cuban divorce was fraudulent. Based on the factual record presented to us, Tomasa
                  has not provided clear and convincing evidence that the Cuban divorce is invalid.
               
               FACTUAL BACKGROUND
               Tomasa R~, formerly Tomasa Maria J~, had two children with Amado R~ in Cuba: Amado
                  Lazaro and Rosalba R~ (Ex. 5). Both Tomasa and NH were natives of Cuba, and according
                  to Tomasa they had an agreement to get married so they could bring their children
                  to the United States. Tomasa came to Brooklyn some time in 1956 and Amado came shortly
                  after. Tomasa and NH were married in New York, N.Y. on September 22, 1957 in a ceremony
                  solemnized by clergyman, Reverend Antonio G~ (Ex. 7). Tomasa and NH listed Brooklyn
                  as the place of their residence (Ex. 7).
               
               Tomasa and NH separated some time around 1960, and NH returned to Cuba while Tomasa
                  remained in New York (Ex. 5). The record contains a Cuban Divorce Decree dated May
                  25, 1960 (Ex. 1). The decree identifies Tomasa, represented by "Solicitor Francisco
                  Rodriguez," as the plaintiff (Ex. 1). NH's statement to the Social Security Administration
                  ("SSA") explains that Tomasa was living in Brooklyn at the time of the divorce but
                  sent power of attorney to Cuba (Ex. 3). Leonor, NH's third wife, similarly told the
                  SSA that Tomasa signed away power to NH in order for him to obtain the divorce from
                  her (Ex. 13). Yet, in Tomasa's request for hearing Tomasa maintained that she is the
                  legal wife of NH (Ex. 9). Tomasa denied receiving any divorce papers (Ex. 2). She
                  claims that the divorce was fraudulent and denied any knowledge of the proceeding
                  and signing her name to any consent or acknowledgment of the divorce action (Ex. 5).
               
               On or about December 31, 1960, NH married Isabel R~, formerly Isabel P~, in Cuba (Ex.
                  4). They remained married for approximately twenty one years until NH brought a divorce
                  action in Elizabeth, N.J. and the Honorable John P. W~ ordered that the marriage be
                  dissolved on September 16, 1982 (Ex. 4). Isabel remarried on March 18, 1983 to Jose
                  H~ and is still legally married to him (Ex. 12). She does not receive, nor is she
                  entitled to, any benefits on NH's record (Ex. 12).
               
               The record indicates that in 1963, subsequent to NH's marriage to Isabel, Tomasa instituted
                  a proceeding for support against NH under Article 4 of the Family Court Act (Ex. 8).
                  In this proceeding the Family Court of the State of New York issued an Order of Support,
                  finding NH legally chargeable with the support of "Wife, Tomasa R~." The Order further
                  directed that NH's "Alleged Cuban Divorce is Void" (Ex. 8). According to Tomasa, it
                  was not until she filed for this Order of Support that she became aware of the fraudulent
                  divorce proceedings (Ex. 5).
               
               The State of New Jersey Certificate of Marriage contained in the file demonstrates
                  that NH was then married a third time on December 7, 1984 to Leonor Maria R~ (now
                  Leonor R~) in Elizabeth, N.J. (Ex. 10). NH died in Miami, Florida on April 27, 2002
                  (Ex. 11). The Certificate of Death acknowledges that NH was a Florida resident at
                  that time (Ex. 11). In her statement to the SSA, Leonor certified that she and NH
                  were married and living together up until the day NH passed away (Ex. 13).
               
               After NH's death, Tomasa applied for surviving spouse benefits on NH's record (Ex.
                  14). On or about November 29, 2002 the SSA notified Tomasa that she was not entitled
                  as a wife because of NH's subsequent marriages, and she was not entitled as a divorced
                  wife because she did not meet the duration of marriage (Ex. 14). Upon reconsideration,
                  that determination was affirmed, reiterating that the divorce has been proven and
                  that the marriage did not last for the requisite ten years (Ex. 14). Still, Tomasa
                  maintains that she is the legal wife of NH, entitled to widow's benefits.
               
               ANALYSIS
               In examining widow's benefit claims, the SSA must look to the laws of the state where
                  the wage earner was domiciled at the time of his death to determine whether claimant
                  qualifies as the wage earner's widow. Social Security Act, 42 U.S.C. § 416(h)(1)(A)
                  (2004). In this case, NH apparently was domiciled in Florida at the time of his death.
                  As such, we must determine whether Florida would recognize the existence of a valid
                  marriage between Tomasa and NH.Under Florida law, the validity of a marriage is determined
                  by the law of the state in which the marriage was contracted. See Smith v. Anderson, 821 So.2d 323, 325 (Fla. Dist. Ct. App. 2002). Thus, according to Florida law, the
                  marriage between Tomasa and NH will be considered valid if it is valid under the law
                  of New York, where the marriage occurred.
               
               1. The Presumption of Validity Attaching to the Amado-Leonor Marriage:
               The record indicates that NH had two other marriages subsequent to his marriage to
                  Tomasa. NH married his third wife, Leonor, in New Jersey in 1984 and remained married
                  to her until he died in 2002. Both Florida and New York recognize a strong presumption
                  in favor of holding the last of subsequent ceremonial marriages valid. See Grabois v. Jones, 89 F.3d 97, 100 (2d Cir. 1996); In re Lee's Estate, 360 So.2d 1111, 1111 (Fla. Dist. Ct. App. 1964). See also Seidel v. Crown Industries, 517 N.Y.S.2d 310, 311 (N.Y. App. Div. 1987) (stating that the presumption in favor
                  of validity of the last marriage is stronger than the presumption that the prior marriage
                  continued); Grace v. Grace, 162 So.2d 314, 317 (Fla. Dist. Ct. App. 1964)(describing the presumption as so great
                  that in the absence of competent proof to the contrary, it is to be assumed that the
                  previous marriage has been dissolved either by death or legal action). This presumption
                  operates to effectuate "a particular public policy such as upholding legitimacy, favoring
                  the participation in the decedent's estate of one who lived with him as his spouse,
                  and preserving the validity of a marriage where no strong public policy would be served
                  by doing otherwise." See Dolan v. Celebrezze, 381 F.2d 231, 237 (2d Cir. 1967). Accordingly, NH's marriage to Leonor is presumptively
                  valid under New York law, and she appears to be the legal widow of NH.
               
               However, it is well established that a marriage is void if contracted by a person
                  whose spouse by a former marriage is living and that former marriage has not legally
                  been dissolved. See Gonzalez v. Gonzalez, 228 N.Y.S.2d 4, 5 (N.Y. Sup. Ct. 1962). Thus, the presumptive validity of the Amado-Leonor
                  marriage may be rebutted if Tomasa provides evidence which, when weighted collectively,
                  establishes with reasonable certainty the fact of the absence of a divorce. See Teel v.
                     Nolen Brown Motors, Inc., 93 So.2d 874 (Fla. 1957). Since the file contains a Cuban divorce decree,
                  Tomasa must provide sufficient evidence to prove the Cuban divorce invalid in order
                  to demonstrate that she is the widow of NH.
               
               2. Effect of the New York Family Court's Determination:
               A judgment in rem is res judicata as to all the world with regard to the res that is determined therein. Presbrey v.
                     Presbrey, 179 N.Y.S.2d 788, 792 (N.Y. App. Div. 1958). In a matrimonial action there is a
                  marital res subject to in rem jurisdiction, therefore a judgment determining marital
                  status subsists as a judicial declaration and is binding on the whole world. Id. at 792. The record indicates that in 1963 the Family Court of the State of New York
                  issued an Order of Support, finding NH legally chargeable with the support of "Wife,
                  Tomasa R~." The Order further directs that NH's "Alleged Cuban Divorce is Void." On
                  its face, the Family Court's decision appears to be a judicial declaration of a subsisting
                  marriage between NH and Tomasa, which rests upon a foundation of an invalid divorce.
               
               a. Issue of Subject-Matter Jurisdiction
               In this case, there is a question as to whether the Family Court had jurisdiction
                  to determine that the divorce is void, and thus whether that court's finding is binding
                  on an Administrative Law Judge deciding Tomasa's entitlement to widow's benefits.
                  The Family Court, formerly known as the Domestic Relations Court, was established
                  and the Legislature conferred such jurisdiction upon it as was essential to permit
                  it to oblige the support of a wife by a husband who had neglected to support her.
                  See N.Y. Const. of 1894, art. VI, § 18 (1925, repealed 1962); N.Y. Dom. Rel. Ct. Act.
                  § 91 (L. 1933, c. 482, as amended); N.Y. Const. art. VI, §§ 13 and 32 (1961, amended
                  2001, effective 2002). In the exercise of its limited jurisdiction the Family Court
                  is authorized to determine whether the parties are husband and wife, but such determination
                  is incidental to the exercise of any jurisdiction. Loomis v. Loomis, 42 N.E.2d 495, 496 (N.Y. 1942). For that limited purpose the court has jurisdiction
                  of the subject matter of the marriage. Consequently, New York law does not recognize
                  a Family Court's pronouncement of marital status as a "decree of a court of competent
                  jurisdiction rendered on the merits," and such a determination is not binding on the
                  parties in a subsequent action outside the Family Court in which there is directly
                  involved the question of whether the same marriage exists or has been terminated.
                  Id. at 496.
               
               In Loomis, the Court of Appeals of New York held that a determination by the Domestic Relations
                  Court of the marital status of the parties is a preliminary matter to exercising or
                  declining jurisdiction and is not binding on the parties in a subsequent action in
                  the Supreme Court where the existence of a valid marriage is directly involved because
                  there is no identity of jurisdiction or cause of action. Id. at 496 (explaining that one is incidental, the other primary, and that one is for
                  support only, the other for an adjudication of marital status). Similarly, the Family
                  Court's direction that the "Cuban Divorce is Void" should not be binding in a subsequent
                  administrative hearing wherein it will be determined whether Tomasa is the legal widow
                  of NH. The Family Court's decision was only incident to its finding that NH was responsible
                  for supporting Tomasa. Thus, the preliminary matter of the marital status in Family
                  Court is not res judicata.
               
               Since the jurisdiction to determine the subject of marriage, where the validity of
                  such marriage is a primary issue, lies exclusively in the Supreme Court, the Family
                  Court's finding is not determinative and Tomasa can rely on it only as evidence. See Graves v. Graves, 675 N.Y.S.2d 843, 846 (N.Y. Sup. Ct. 1998)(stating the New York Supreme Court has
                  exclusive subject matter jurisdiction over divorce actions).
               
               b. Issue of Failure to Include an Indispensable Party
               Assuming arguendo that a court is unconvinced by subsection (a) supra, and avers the
                  Family Court's decision should be res judicata for public policy reasons such as consistency, an additional defect remains in such
                  an assertion. The noncompulsory nature of the court's judgment regarding marital status
                  is evident with an acknowledgment that Isabel, NH's second wife to whom he was married
                  at the time of the proceeding, was not a party to the action.
               
               It is well-known that a court may always consider whether there has been a failure
                  to join a necessary party. See First Nat. Bank v. Shuler, 47 N.E. 262, 264 (N.Y. 1897); Matter of Lezette v. Bd. of Educ., 319 N.E.2d 189, 195 (N.Y. 1974). Necessary parties are those persons who might be
                  "inequitably affected by a judgment in the action." N.Y. C.P.L.R. 1001 (M~ 2005).
                  With regard to necessary parties, the N.Y. C.P.L.R. 3001 provides that an action for
                  a declaration of legal relations serves a legitimate purpose only where all persons
                  who are interested in or might be affected by enforcement of such rights and legal
                  relations are parties to the action and have the opportunity to be heard. N.Y. C.P.L.R.
                  § 3001 (M~ 1991)(derived from N.Y. C.P.A. of 1920 § 473). This insures fairness to
                  third parties who should not be "embarrassed by judgments purporting to bind their
                  rights or interest where they have had no opportunity to be heard." First Nat.
                     Bank, 47 N.E. at 264.
               
               New York Courts have held that, where in an action by one spouse for a judgment declaring
                  that a foreign divorce decree is null and void, it appears that subsequent to the
                  procurement of the divorce the defendant married a third person, such third person
                  must be joined as a party defendant, since that person is an indispensable party without
                  whom no effective judgment can be rendered. See, eg., Cominos
                     v. Cominos, 258 N.Y.S.2d. 545, 545 (N.Y. App. Div.), app. dismissed, 213 N.E.2d 687, 687 (N.Y.
                  1965); Bard v. Bard, 228 N.Y.S.2d 294, 294 (N.Y. App. Div. 1962); Varrichio v. Varrichio, 53 N.Y.S.2d 326, 326 (N.Y. App. Div.), app. denied, 56 N.Y.S.2d 527, 527 (N.Y. App.
                  Div. 1945).
               
               Here, NH was married to Isabel at the time of the Family Court's proceeding. Although
                  the court's declaration of the nullity of the Cuban divorce related primarily to the
                  marital status of NH and Tomasa, it also necessarily implied that the Amado-Isabel
                  marriage was void, thus affecting the rights and legal relation of Isabel. Consequently,
                  Isabel was a necessary and indispensable party without whom no effective judgment
                  regarding marital status could have been rendered. Accord
                     Bard, 228 N.Y.S.2d at 296; see also First Nat. Bank, 47 N.E. at 264 (stating that the rule requires that without the presence of all
                  persons whose rights may be affected by the judgment there cannot be a final and complete
                  determination of the controversy). The fact that Isabel was not a party to the action
                  confirms that the court's finding of a surviving marriage is not binding in Tomasa's
                  administrative hearing concerning her eligibility for widow's benefits. It is, thus,
                  our opinion that the ALJ may form his own conclusion with respect to whether a marriage
                  subsists or whether the Cuban Divorce is valid.
               
               3. Recognition of the Cuban divorce decree
               In determining whether Tomasa is the legal widow of NH, the issue of marital status
                  is complicated by the contradictory evidence regarding the divorce. Tomasa contends
                  that she was separated from NH for over 39 years, but was never served with divorce
                  papers. However, NH submitted proof of the Cuban divorce when he applied for Social
                  Security benefits. The first question to be determined is the extent to which recognition
                  must be accorded the Cuban divorce decree in a New York court. Secondly, the possibility
                  that the divorce may have been fraudulently obtained must be considered.
               
               a. The Doctrine of Comity
               New York courts will generally accord recognition to the judgments rendered in a foreign
                  country under the doctrine of comity which is the equivalent of full faith and credit
                  given by the courts to judgments of our sister States. See, e.g.,
                     Greschler v. Greschler, 414 N.E.2d 694, 697 (N.Y. 1980); see, generally, Restatement (Second) of Conflict of Laws § 98 (1971); Robert A. L~, American Conflicts
                  Law § 84, at 169-171 (3d ed. 1968). A party who properly appeared in a foreign divorce
                  action is precluded from attacking the validity of the foreign judgment in a collateral
                  proceeding brought in the New York courts, absent some showing of fraud in the procurement
                  of the judgment or some showing that recognition of the judgment would violate a strong
                  public policy of the State. See Greschler, 414 N.E.2d at 697-698.
               
               In the case at bar, Tomasa has failed to adduce evidence demonstrating that the Cuban
                  court did not have personal jurisdiction over her. The record includes the translation
                  of the Cuban Decree which indicates that Tomasa was the plaintiff and was represented
                  by Solicitor Francisco Rodriguez. Thus, her appearance, through an attorney, in the
                  divorce action gave the Cuban court jurisdiction to grant the divorce unless such
                  appearance was unauthorized. Accordingly, the ALJ would recognize the Cuban divorce
                  decree under the doctrine of comity unless Tomasa can demonstrate fraud or a violation
                  of public policy. See Bourbon v.
                     Bourbon, 751 N.Y.S.2d 302, 304 (N.Y. App. Div. 2002).
               
               b. Demonstrating Fraud
               The Social Security Act authorizes the Commissioner to adopt reasonable and proper
                  rules and regulations regarding the nature and extent of proof and evidence necessary
                  to establish the right to benefits. 42 U.S.C. § 405(a) (2006). SSA regulations clearly
                  identify a claimant's responsibilities for proffering convincing evidence to fulfill
                  eligibility requirements for benefits. 20 C.F.R. §§ 404.704, 404.708 (2006). In deciding
                  whether evidence is convincing, the SSA will look to whether "information contained
                  in the evidence agrees with other available evidence, including our records." 20 C.F.R.
                  § 404.708(f) (2006).
               
               Here, the record contains evidence of a valid divorce between NH and Tomasa as well
                  as NH's subsequent marriages. This evidence conflicts with Tomasa's claim that she
                  is the widow of NH as well as the determination of the Family Court that the Cuban
                  divorce is void. Since Tomasa bears the ultimate burden of proving that she is entitled
                  to benefits as NH's widow, it is her obligation to provide clear and convincing evidence
                  that the divorce is invalid on the ground of fraud. Here, the evidence is inconclusive.
                  Tomasa has not produced any records which tend to show that she did not bring the
                  divorce suit or that her power of attorney was unauthorized. Tomasa, therefore, has
                  not carried her burden of proof. Consequently, if no further evidence is submitted,
                  the presumption of validity attaching to NH's marriage with Leonor will continue,
                  New York courts will give recognition to the divorce decree, and Tomasa cannot receive
                  benefits as NH's widow.
               
               4. Divorced Wife's Benefits
               Section 202(e) of the Social Security Act provides that widow's insurance benefits
                  may be paid to a divorced wife. Social Security Act, 42 U.S.C. § 402e (2006). An applicant
                  for a surviving divorced spouse's insurance benefit must meet several requirements:
                  she must have been validly married to a fully insured worker for a period of at least
                  ten years immediately preceding a final divorce; must have attained age 60, or have
                  attained age 50 and be under a disability; and must also be unmarried. 42 U.S.C. §§
                  402(e), 402(b)(1), 416(d)(1) (2006).
               
               It is evident that Tomasa R~ is ineligible for divorced wife's benefits. Although
                  she meets the second two requirements - she is 85 years of age and has never been
                  remarried - the duration requirement has not been met. The divorce occurred in 1960,
                  less than three years after Tomasa and NH married. Since the marriage subsisted for
                  less than ten years, Tomasa cannot receive divorced wife's benefits on NH's account.
               
               In conclusion, on our understanding of the current factual record, Tomasa cannot be
                  entitled to widow's benefits on NH's account because she has not proven through clear
                  and convincing evidence that she is the legal wife of NH. See Seidel
                     v. Crown Industries, 517 N.Y.S.2d 310, 311 (N.Y. App. Div. 1987). A further development of the facts
                  may establish that the Cuban divorce is void. However, Tomasa bears the burden of
                  proof and if no further evidence is provided she has not met her burden.
