You have asked our assistance in determining whether Genevieve G~ is entitled to Social
                  Security benefits on the account of he former husband, Vito M~ . We conclude that
                  Ms. G~ is not entitled to such benefits.
               
               We understand that Genevieve G~ and the wage earner, Vito M~ , were married in Wayne
                  County, Michigan on November 9, 1940. They were divorced in 1950. The Circuit Court
                  of Wayne County entered an interlocutory divorce decree on May 3, 1950. Under the
                  terms of that decree, the divorce became final six months from the day of entry. The
                  parties were thus finally divorced on November 3, 1950.
               
               On November 12, 1981, Ms. G~ applied for benefits on Vito M~'s account. Because they
                  had been married for less than ten years, her application was denied and her subsequent
                  request for reconsideration was also denied. Ms. G~ subsequently petitioned the circuit
                  court to change the decree's entry date to May 17, 1950. Ms. G~ advised the Court
                  and the Social Security Administration that she sought this change solely for the
                  purpose of qualifying for Social Security benefits on her husband's account. Her petition
                  was not contested and on June 2, 1983, the court entered a decree, nunc pro tunc,*
                  changing the date as requested.
               
               Notwithstanding the circuit court decree, we conclude that Ms. G~ is not entitled
                  to benefits upon Vito M~'s account because she does not satisfy the ten year marriage
                  requirement. As we have stated in prior opinions, the Secretary is not bound by a
                  state court judgment deciding family status questions where the judgment does not
                  meet each of four criteria set forth by the Sixth Circuit Court of Appeals in Gray v. Richardson, 474 F.2d 1370 (6th Cir. 1973). G~, RA V (H~) to ARC, Programs V, 7/8/82; F~ ,~ ,
                  RA V (H~) to Director, Insurance Programs Branch V, 3/30/82. The Gray criteria are: 1) the state court has jurisdiction over the issue; 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.
               
               Two of the Gray criteria are not met in this case. First, it appears that the issue was not genuinely
                  contested before the state court and second, the court decision is not consistent
                  with the law enunciated by the highest court in the State of Michigan.
               
               A nunc pro tunc entry, in practice, is an entry made now of something which was actually
                  previously done, to have effect as of the former date. Its office is not to supply
                  omitted action by the court, but to supply an omission in the record of action really
                  had, but omitted through inadvertence or mistake.
               
               Magoun v. Walker, 286 Mich. 686, 282 N.W.2d 868 (1938); quoting Perkins v. Hayward, 132 Ind. 95, 31N.E. 670 (1892); Freeman v. Hulbert, 230 Mich. 455; 203 N.W. 158, 160 (1925), People v. Gregory, 174 N.W. 2d 905 (1969). Thus, in Freeman v. Hulbert, supra, the Michigan Supreme Court ruled that the nunc pro tunc entry of an order
                  was appropriate where the trial judge had authorized the administrator of an estate
                  to hire counsel but the order had not been recorded. The Court emphasized that its
                  role was not to "supply now some judicial action omitted." Rather, its action merely"
                  perfect[ed] of record action heretofore judicially had." Id. at 159. Similarly, in Far- mer v. Farmer, 200 Neb. 308; 263 N.W.2d 664----[1978), the Nebraska Supreme Court upheld an order
                  nunc pro tunc to correct a decree in which the petitioner's name was inadvertently
                  typed in place of respondent's. In contrast, in Magoun v. Walker, supra, the Michigan Supreme Court denied the nunc pro tunc entry of an order which
                  would have corrected errors in the "return of service" of notice to redeem land after
                  a tax sale. There, the court reasoned that since the return did not meet statutory
                  requirements an amended return could not relate back "and make good that which was
                  not good on October 28, 1930." Id. at 869.
               
               In divorce cases a judgment nunc pro tunc is usually used if the "entry of the decree
                  has been omitted or delayed through inadvertence or mistake, or the decree has otherwise
                  not been properly entered." Vioglavich  v. Vioglavich, 317 N.W.2d 633, 637 (1982). The Michigan Supreme Court has strictly limited the
                  use of the nunc pro tunc judgment as a method of changing the effective date of a
                  divorce. In Tiedman v. Tiedman, 255 N.W.2d 632 (1977), for example, the Court refused to enter such judgment, nunc
                  pro tunc. There, during court proceedings, the divorce court judge indicated that
                  he was satisfied that all requirements had been met and that "upon presentation" he
                  would sign the judgment of divorce. After the court appearance but before the judgment
                  was signed, the husband died. The Court refused to enter the judgment, nunc pro tunc,
                  effective the date of the court appearance because judgment had not actually on been
                  entered that day.
               
               In Saunders v. Smith, 272 N.W.2d 174 (1978) the Michigan supreme court again refused to alter the effective
                  date for entry of a divorce decree. There, on the date of the court hearing, the trial
                  judge agreed that the divorce judgment would be "given immediate effect" even though
                  the written judgment had not been prepared. One of the parties died before the written
                  judgment was entered. The Court of Appeals affirmed a nunc pro tunc entry of judgment
                  effective the date of trial, reasoning that the judge had actually entered judgment
                  at that time. The Michigan Supreme Court reversed and stated that since the judge's
                  oral statement was to be followed by signing of a written judgment, the divorce could
                  not be effective until the judgment was signed. Saunders  v. Smith, 289 N.W.2d 925 (1979).
               
               Underlying these decisions is the principle that entry of a judgment nunc pro tunc
                  is designed to correct errors to reflect what actually occurred. It may not be used
                  to alter or amend an existing judgment nor to change the date that judgment was actually
                  entered.
               
               Courts in other jurisdictions have reached similar results. See  White v. White, 203 Neb. 782, 280 N.W. 2d 78 (1979) ("The proper function of an order nunc pro tunc
                  is to correct the record which has been made so it will truly reflect the action really
                  had. The order must conform to and be no broader in its terms than the judgment or
                  decree actually entered."); Strawser v. Strawser, 126 Wis.2d 485, 377 N.W.2d 196 (1985) ("A court's nunc pro tunc authority is thus
                  limited to rectifying what might be termed 'mechanical errors' in our judicial system.")
               
               In this case, Ms. G~ has not claimed that the May 3, 1950 date on her divorce decree
                  was in error. Instead, Ms. G~ has attempted to change the court's decree through the
                  entry of a nunc pro tunc order. Such change is precluded by state law as set forth
                  in the decisions of the state supreme court. Ms. G~ is thus not entitled to benefits
                  on Mr. M~ 's account because she fails to satisfy the ten year marriage requirement.
               
               * Although the decree reads "non pro tunc," we assume that this was simply an error
                  in drafting and has no significance.
