The wage earner, John J~, married Maria P~ in Ryczywol, Poland on July 11, 1940. Several
                  months later, he left Poland for the United States. Maria, then as now a Polish citizen,
                  stayed in Poland. Mr. J~ was inducted into the United States Army in 1942, and remained
                  in the service after the war. During 1948 he was stationed in California.
               
               On July 16, 1948 Mr. J~ filed a complaint for divorce in a Nevada state court, alleging
                  that he had been a bona fide resident of Nevada for more than six weeks. In an accompanying
                  affidavit, Mr. J~ averred that he had attempted to locate Maria through correspondence,
                  as well as other unspecified means, but had been unsuccessful. He further stated that
                  Maria's last "address" to his knowledge was Rozgona, Poland. On the strength of this
                  affidavit, the Nevada court ordered publication of a summons in the Reno Evening Gazette,
                  finding that this was "the newspaper most likely to give notice to defendant [Maria]
                  of the pendency of the suit." The court also directed that copies of the summons and
                  complaint were to be mailed to Maria, addressed only to Rosgona [sic], Poland. Maria
                  has since stated that she did not receive the summons and complaint and had no knowledge
                  of the divorce proceedings until 1950.
               
               A divorce decree dissolving the marriage was issued on September 14, 1948. On the
                  same day, Mr. J~ married Ruth H~. Shortly thereafter Mr. J~ and Ruth returned to his
                  military base in California.
               
               Mr. J~ applied for retirement insurance benefits on April 4, 1978. Ruth submitted
                  an application for wife's benefits on January 10, 1983. On October 11, 1983 Maria
                  also filed for wife's benefits, alleging that her marriage to Mr. J~ was never legally
                  ended. You have asked for our assistance in determining the validity of the Nevada
                  divorce for purposes of adjudicating Maria's claim.
               
               Pursuant to section 216(h) (1) (A) of the Social Security Act, the determination of
                  whether the wage earner and Maria remained married, notwithstanding the Nevada divorce
                  decree, is to be based on the laws of the state in which Mr. J~ was domiciled at the
                  time of Maria's application. You have found that the state of domicile in this case
                  is California. Therefore, California law governs the outcome.
               
               Under California law, and consistent with the constitutional principle of full faith
                  and credit, the validity of a divorce decree is determined by the laws of the state
                  in which it was obtained. In Re Estate of Grimble, 42 Cal.App.3d 741, 117 Cal.Rptr. 125 (1974); Jones v. Jones, 182 Cal.App.2d 80, 5 Cal.Rptr. 803 (1960); see Williams v. North Carolina, 325 U.S. 226, 65 S.Ct. 1092 (1945). However, "[a] divorce decree is not entitled
                  to obligatory recognition and enforcement under the full faith and credit clause of
                  the federal Constitution unless it is rendered by a court having jurisdiction over
                  the Subject matter and the parties" (emphasis in original). 6 Witkin, Summary of California Law, "Husband and Wife" 71 (8th ed.). Where jurisdiction is
                  in doubt, a California court may reexamine the jurisdictional bases asserted by the
                  court of its sister state. Leff v.  Leff, 25 Cal.App.3d 630, 102 Cal.Rptr. 195 (1972), citing Williams  v. North Carolina, cited above. GC opinion re Nathan  N. Carroll, May 12, 1978.1/ In our opinion a reexamination of the circumstances of this case
                  would result in a finding that the Nevada court had no jurisdiction and that, consequently,
                  the divorce decree is invalid.
               
               In a divorce action, as in any judicial proceeding, due process requires a method
                  of notice reasonably calculated to afford the interested parties the opportunity to
                  appear and be heard. Milliken v.  Meyer, 311 U.S. 457, 61 S.Ct. 339 (1940). If the means of notification used is not designed
                  to apprise those concerned of the pendency of an action, the court entertaining that
                  action does not acquire personal jurisdiction and any resulting decree lacks binding
                  effect. GC opinion re Harold Eidelbus, June 13, 1984, citing Mullane v. Central Hanover Bank and  Trust Company, 339 U.S. 306, 70 S.Ct. 652 (1950). A decree of divorce rendered by a court devoid
                  of jurisdiction for want of adequate notice can be impeached collaterally even when
                  the record purports to show jurisdiction. Williams v. North Carolina, cited above. The notification procedures in this case did not satisfy minimal constitutional
                  requirements.
               
               The Reno Evening Gazette, an English language newspaper of limited circulation, was
                  not an appropriate vehicle for conveying notice of the divorce proceedings to Maria.
                  Service of process by publication has long been constitutionally suspect. Mullane  v. Central Hanover Bank and Trust Company, cited above. Publication in this local paper was plainly not an effective means
                  of notifying the Polish-speaking defendant, Maria, who had never been to the United
                  States, let alone Reno, Nevada.
               
               Nor was the deficient notification cured by the expedient of mailing a copy of the
                  summons and complaint to Maria, addressed only to the Polish town of Rozgona. Service
                  by mail is not inadequate per se, but it will suffice only when preceded by a diligent
                  attempt to ascertain the exact whereabouts of the defendant. Donel,  Inc. v. Badalian, 87 Cal.App.3d 327, 150 Cal. Rptr. 855 (1978); accord Mullane v. Central Hanover Bank and Trust Company, cited above. In this case there was no factual showing that Mr. J~ had made a good
                  faith effort to locate his wife. The mere recitation in the affidavit that unspecified
                  attempts to locate Maria were unsuccessful is not sufficient, nor is facial compliance
                  with the Nevada statute concerning process. Donel, Inc. v. Badalian, cited above, citing Stern v. Judson, 163 Cal. 726, 127 P.. 38 (1912). Certainly, there is no indication that Maria tried
                  to conceal her place of residence or otherwise avoid service of process. Under these
                  circumstances, the California courts would conclude that notice was inadequate, that
                  Maria was not given a fair opportunity to contest the divorce, and that, therefore,
                  the Nevada court lacked personal jurisdiction, rendering the divorce decree invalid.2/
               
               The Nevada decree is also vulnerable on other and independent grounds:
               "It is a well established rule that jurisdiction to grant a divorce rests upon bona
                  fide domicile. When neither party is domiciled within the state, no divorce can validly
                  be granted and all proceedings, as well as the judgment, are void. Stated another
                  way, a decree of divorce rendered in one state may be impeached and denied recognition
                  in another upon the ground that neither of the parties had domicile at the divorce
                  forum, and this is true notwithstanding the recital in the decree from the other state
                  of the jurisdictional fact of domicile or residence. See: Beale, Conflict of Laws, vol. 1, 74.3, 111.1 and cases cited therein; Goodrich, Conflict of Laws, 2nd Ed. 123; Rest., Conflict of Laws, 111; 9 Cal. Jur. 815, 817."
               
               Johnson v. Johnson, 259 Cal.App.2d 139 66 Cal. Rptr. 172, 176 (1968), quoting Crouch v. Crouch, 28 Cal.2d 243, 169 P.2d 897, 900 (1946); accord Williams  v. North Carolina, cited above; Latterner v. Latterner, 51 Nev. 285, 274 P. 194 (1929) (jurisdiction to award divorce decree dependent upon
                  bona fide residence). In reviewing a collateral attack on jurisdiction due to lack
                  of domicile, a court may consider evidence apart from the record, including evidence
                  of extrinsic fraud. GC opinion re Nathan N. Carroll, cited above. The evidence on file in this case warrants a finding that Mr. J~ was
                  never actually domiciled in Nevada. ..
               
               Recent statements by Mr. J~ indicate that he did not even satisfy the minimal residential
                  requirements of Nevada. Then, as now, Nevada required the plaintiff in a divorce action
                  to have resided in the state for at least six weeks prior to filing suit. NCL 9460;
                  accord Nevada Revised Statutes (NRS) 125.020. The complaint in this case alleges that
                  Mr. J~ had resided in Nevada for more than six weeks prior to commencement of the
                  action on July 16, 1948. Mr. J~ statements to SSA belie this allegation. On December
                  20, 1984 he stated that he did not begin his residence in Nevada until July 15, 1948,
                  just one day before the com- plaint was filed. It is also noteworthy that he was only
                  able to stay in Nevada by drawing on 90 days of accumulated military leave. Had he
                  come to Nevada six weeks prior to July 16, 1948, this leave would have been exhausted
                  by late August or the first week of September at the latest. However, the record shows
                  that he was in Nevada through September 14, 1948. Presented with this evidence demonstrating
                  non-compliance with the six-week residency requirement, the California courts would
                  not honor the Nevada decree. See Johnson v. Johnson, cited above.
               
               Even if the statutory residency requirements had been met, the decree would not be
                  valid because jurisdiction attaches only when physical residence is combined with
                  a genuine intention to remain indefinitely within the state. E.g., Presson v. Presson, 38 Nev. 203, 147 P. 1081 (1915). There is no evidence, aside from the bare allegation
                  in the complaint, that Mr. J~ ever really considered staying in Nevada beyond the
                  minimum time required to process his divorce. In a statement dated April 5, 1985,
                  he indicated that he thought of Maryland as his state of residence until 1949. In
                  addition, nothing in the file indicates that Mr. J~ lingered in Nevada after the divorce
                  for so much as 24 hours, or that he ever returned to that state to resume residence.
                  We believe the California courts would refuse to uphold the Nevada decree on the basis
                  of the very suspect record with respect to residence and domicile.
               
               Finally, you inquire whether Maria is estopped from con- testing the divorce because,
                  although she became aware of the decree in 1950, she took no action to have it set
                  aside. A divorce judgment void for want of jurisdiction may be vacated at any time
                  unless the equitable defenses of estoppel or laches apply. 24 Am. Jur.2d, "Divorce
                  and Separation" 486. Since there is no evidence that Maria relied upon the divorce
                  to her advantage (e.g., by remarrying or accepting alimony), she would not be estopped
                  from challenging the decree. Id. at 488.
               
               Nor could laches be invoked to forestall an attack on the divorce. Laches consists
                  of failure by the plaintiff to assert her rights in a timely fashion, resulting in
                  some detriment or prejudice to the defendant. See, e.g., Rouse v. Underwood, 242 Cal.App.2d 316, 51 Cal. Rptr. 437 (1966). The period of delay in this case was
                  extreme, approximately 35 years having elapsed from the date Maria learned of the
                  divorce until she alleged its invalidity in connection with her application for wife's
                  benefits.3/ However, the delay was not prejudicial to Mr. J~. The primary action he
                  took in reliance upon the divorce was his attempted marriage to Ruth on the same day
                  the decree was handed down. Where, as here, remarriage occurred "soon after the divorce
                  and at a time when the other party to the decree could not have been expected to seek
                  relief, . . the delay does not cause sufficient injury to warrant the application
                  of the doctrine of laches." 24 Am. Jur.2d, "Divorce and Separation," at 492. Moreover,
                  laches is an equitable defense, sustainable only when appropriate under the particular
                  circumstances of the case at hand. An equity court reviewing the facts here would
                  be strongly influenced by the disabilities resulting from Maria's residence in Poland.
                  Her presumptive difficulty in comprehending and gaining access to the American legal
                  system would weigh heavily in favor of allowing her to challenge the divorce even
                  at this late date.
               
               For these reasons, we think that the California courts would permit Maria to attack
                  the decree and that such an attack would succeed because the Nevada court lacked personal
                  and subject matter jurisdiction.
               
               1/ Note, however, that a collateral attack on jurisdictional grounds is not permissible
                  where the defendant participated in the divorce proceedings, was accorded a full opportunity
                  to contest jurisdictional issues, and where a collateral attack would not be allowed
                  in the courts of the state in which the decree was issued. Aldabe  v. Aldabe, 209 Cal.App.2d 453, 26 Cal. Rptr. 208 (1962). Collateral attack would be available
                  here since Maria did not appear in the divorce proceedings.
               
               2/ Our conclusion that the court did not acquire personal jurisdiction is not based
                  on Maria's failure to actually receive notification. Where the plaintiff has made
                  a genuine effort to locate the defendant, service by mail is effective even if notice
                  is never received. GC opinion re. Andrea Cardinale, D-15909, December 13, 1972, citing Hubert v. Hubert, 78 Cal.App.2d 498, 178 P.2d 15 (1947).
               
               3/ The file does contain a memorandum, dated May 29, 1950, drafted by a United States
                  military officer and addressed to the "Air Attache, U.S. Embassy, Warsaw, Poland,"
                  which suggests that Maria may have attempted to dispute the divorce soon after she
                  learned of the judgment.
