Lastly, in order a party to successfully maintain an action to nullify a final judgment,
                        all indispensable parties must be joined in the action. See La. Code of Civ. Proc.
                        Ann. art. 641. “An indispensable party is one whose interests in the subject matter
                        are so interrelated, and would be so directly affected by the judgment, that a complete
                        and equitable adjudication of the controversy cannot be made unless they are joined
                        in the action.” Candler v. Candler, 556 So. 2d 261, 263 (La. Ct. App. 1990). Accordingly,
                        in actions to nullify a divorce judgment, a former spouse’s current spouse and any
                        other parties whose interest the annulment would affect should be joined in the action.
                        See id. (reversing the trial court’s annulment of the divorce judgment because the
                        former wife sued the former husband, but failed to join the former husband’s present
                        wife as an indispensable party).
                     
                     Here, this means that I~ and NH’s estate would be indispensable parties. However,
                        the Judgment of Annulment states that NH’s estate did not make an appearance and makes
                        no mention of I~ being joined as a party to the annulment action. Without further
                        information that I~ and NH’s estate were properly joined in this annulment action,
                        we are unable to determine if the Judgment is consistent with Louisiana law.
                     
                     C. SSR 83-37c: The Agency is Not Bound by the Judgment of Annulment
                           BecauseIt is Unclear whether Claimant Obtained a Valid Annulment of her
                           Divorce from NH under Louisiana Law and it is Unclear whether the Annulment
                           was Genuinely Contested
                     Claimant relies solely upon the Judgment of Annulment to support her claim that she
                        was validly married to NH at the time of his death under Louisiana law and thus, NH’s
                        widow under the Act for purposes of obtaining widow’s benefits on NH’s record. Social
                        Security Ruling (SSR) 83-37c instructs the agency on how to consider a state court
                        order. See SSR 83-37c, 1983 WL 31272, at *3 (adopting Gray v. Richardson , 474 F.2d
                        1370 (6th Cir. 1973)); see also POMS GN 00305.065(B)(4). The agency is generally not bound by a state court’s determination if it involves
                        a proceeding to which the agency was not a party. See SSR 83-37c. However, state court
                        determinations of domestic relations matters are entitled to deference and bind the
                        agency if the following four factors are satisfied (Gray factors) :
                     
                     1. an issue in a claim for Social Security benefits was previously adjudicated by
                        a state court of competent jurisdiction;
                     
                     2. the issue was genuinely contested before the state court by parties with opposing
                        interests;
                     
                     3. the issue falls within the general category of domestic relations law; and
                     4. the resolution by the state trial court is consistent with the law enunciated by
                        the highest court in the state.
                     
                     SSR 83-37c. Thus, we consider whether the Judgment of Annulment binds the agency,
                        and even if it does not, whether it would be reasonable for the agency to defer to
                        this state court order as evidence to support Claimant’s claim for benefits on NH’s
                        account as NH’s widow. See Hanson v. Astrue, 733 F.Supp.2d 214, 218 (D. Mass. 2010)
                        (“It would not be inconsistent with [SSR 83-37c] for the Commissioner to follow a
                        state adjudication even though fewer than all the conditions were met, subject to
                        bounds of reason and good faith.”).]
                     
                     1. First and Third Gray Factors 
                     The Judgment of Annulment, which declares NH’s 1996 divorce from Claimant an absolute
                        nullity, satisfies the first and third Gray factors because Louisiana district courts
                        are courts of competent jurisdiction in the domestic relations matters of marital
                        status and in particular over an action to annul a marriage if one or both of the
                        parties are domiciled in Louisiana, which is an issue in this claim for survivor’s
                        benefits. See La. Code Civ. Proc. Ann. art. 10(A)(6). Accordingly, the first and third
                        Gray factors were met.
                     
                     2. Second Gray Factor
                     However, we do not have sufficient information to know whether the Judgment of Annulment
                        meets the second criteria of being genuinely contested. Although the Judgment of Annulment
                        nullifies NH’s divorce from Claimant, NH died on December XX, 2018, prior to Claimant’s
                        petition for nullity. See George v. Sullivan , 909 F.2d 857, 861 (6th Cir. 1990) (a
                        court order did not bind the Commissioner and was not genuinely contested where no
                        evidence was presented or any material controversy resolved). Moreover, the Judgment
                        of Annulment states that NH’s estate did not appear, and it is unclear whether NH’s
                        estate or I~ were properly joined in the action such that parties of opposing interest
                        genuinely contested the issue. Thus, the agency cannot determine whether the second
                        Gray factor was met.
                     
                     3. Fourth Gray Factor
                     Lastly, we must determine whether the Judgment of Annulment met the fourth Gray factor.
                        The Fifth Circuit’s test for determining when a state court order binds the agency
                        generally places an emphasis upon the fourth Gray factor.[[4] ] See Warren v. Sec’y of Health & Human Servs., 868 F.2d 1444, 1446-47 (5th Cir.
                        1989); Garcia v. Sullivan, 883 F.2d 18, 19-20 (5th Cir. 1989). In order to determine
                        whether the Judgment of Annulment meets the fourth Gray factor, we must determine
                        whether the Judgment of Annulment is consistent with Louisiana law.
                     
                     Under narrow circumstances as outlined above, Louisiana law allows for the annulment
                        of final divorce judgments, even after the death of a party. However, as the Louisiana
                        Supreme Court has recognized, there is “a presumption as to the regularity of judicial
                        proceedings” as well as “a strong public policy against disturbing or declaring invalid
                        a judgment of divorce, especially after a long period of time where the marital status
                        of innocent parties who relied on the validity of that judgment would be disturbed,
                        and more particularly where a decree would render innocent parties guilty of bigamy
                        . . . .” Wilson, 59 So. 2d at 453.“[E]very presumption will be indulged in favor of
                        a judgment that is collaterally attacked.” Id. at 455. Thus, “[i]n order to prevail,
                        plaintiff must therefore establish with certainty the invalidity of the judgment which
                        he attacks.” Id. at 453. As explained above, in order for a party to maintain an action
                        to nullify a divorce after death, the party must prove the grounds for annulment by
                        “exceptionally strong and convincing proof.” See Patton, 86 So. 2d at 58.
                     
                     As we have addressed in detail above, here, the Judgment of Annulment does not state
                        the basis of the nullification as a vice of form or a vice of substance. Thus, we
                        are unable to determine if the Judgment of Annulment was properly entered based on
                        a vice of form or vice of substance.
                     
                     Further, in light of her 2015 application for benefits on NH’s record as his divorced
                        spouse at which time she inconsistently asserted to the agency they were divorced
                        and provided the Judgment of Divorce, we believe that we cannot rely on the Judgment
                        of Annulment. First, given her actions in filing for divorced spouse’s benefits in
                        2015, there is a strong possibility that a Louisiana court would find that she voluntarily
                        acquiesced to the Judgment of Divorce, thus precluding an annulment action based on
                        vice of form. Additionally, we believe there is a strong possibility that a Louisiana
                        court would find that her action was time barred under Louisiana law given her knowledge
                        of the divorce in 2015, four years prior to her action to annul the divorce until
                        2019. See Patton, 86 So. 2d at 58 (plaintiff’s action brought in 1948 to annul the
                        divorce judgment based on a vice of substance due to fraud was barred by the one-year
                        prescriptive period since she knew of the divorce at least as of 1931 and knew that
                        the ex-husband had remarried).
                     
                     Additionally, the agency does not have any of the supportive documents Claimant may
                        have presented to the Court in support of her 2019 petition to nullify the 1996 Judgment
                        of Divorce. The Judgment of Annulment does not explain that the court applied the
                        proper standard of “exceptionally strong and convincing proof” and found evidence
                        sufficient to overcome the strong presumptions and strong policies outlined above
                        as to final divorce judgments. This is of particular concern in a case such as this
                        where the divorce had been obtained 23 years prior, NH remarried I in 2003, and Claimant
                        presented the Judgment of Divorce to the agency to support her claim for divorced
                        spouse’s benefits on NH’s record. Further suspect is that Claimant did not initiate
                        the annulment action until after NH’s death and until after she was denied divorced
                        spouse’s benefits because their marriage did not meet the 10-year marriage duration
                        requirement. As the Louisiana Supreme Court explained, “where the status of another
                        would be seriously impaired if the judgment of divorce was to be set aside . . . in
                        dealing with the equities, we are bound to give consideration to the second marriage
                        which was contracted in good faith of the judgment under attack and also scrutinize
                        the motives which prompted plaintiff to seek the annulment of the judgment after her
                        former husband’s death.” Wilson, 59 So. 2d at 453. Claimant’s motives are questionable
                        in light of her applications for benefits on NH’s record and the timing of her action
                        to annul their divorce.
                     
                     Because the basis for the nullification is unknown, it is unclear whether Claimant
                        met her burden of exceptionally strong and convincing proof, and it is unknown whether
                        I~ and NH’s estate were joined as indispensable parties, it is not possible to determine
                        whether the Judgment of Annulment is consistent with Louisiana law.
                     
                     4. Summary: Judgment of Annulment Does Not Bind the Agency
                     In applying SSR 83-37c and the Gray factors, we believe that the Judgment of Annulment
                        does not bind the agency, nor should the agency defer to such Judgment because we
                        have concerns about its validity and are unable to determine whether the Judgment
                        is consistent with Louisiana law.
                     
                     Conclusion
                     Based on the Judgment of Annulment and the information available to the agency regarding
                        Claimant’s application for divorced spouse’s benefits in 2015, we believe there is
                        legal support for the agency to find that Claimant has not proven a valid annulment
                        of her 1996 divorce from NH under Louisiana law. Consequently, Claimant has not proven
                        that she (and not I~) had a valid marriage to NH under Louisiana law at the time of
                        his death. See 42 U.S.C. § 416(h)(1)(A)(i); 20 C.F.R. 404.345. For this same reason,
                        Claimant also has not proven a right to inherit a spouse’s share under Louisiana intestate
                        succession law.[[5] ] See 42 U.S.C. § 416(h)(1)(A)(ii); 20 C.F.R. § 404.345. Therefore, Claimant has
                        not proven the requisite marital relationship with NH for widow’s benefits on his
                        record. See 20 C.F.R. §§ 404.335(a), 404.345.
