We are responding to your request for an opinion as to whether Oklahoma would recognize
                  a Mexican divorce obtained by the husband or whether the wife would be estopped to
                  deny the divorce. For the reasons stated below, we believe that although Oklahoma
                  would not recognize the divorce, the wife would be estopped to deny the divorce.
               
               According to the facts provided, on November 11, 1964, Donald L. M~, through his attorney,
                  petitioned for divorce in Juarez, Mexico, from his wife, Vada E. M~. Neither Donald
                  nor Vada M~ lived in Mexico. The court notified Vada E. M~ of the divorce proceeding
                  in early November, 1964. The Juarez court granted the divorce on December 5, 1964.
                  Vada M~ neither contested nor appealled the divorce. The record indicates that Donald
                  M~ has remarried and lives in Oklahoma. Vada M~ lived in Virginia and has not remarried.
               
               Your request mentioned a February 4, 1972, opinion from this office on Herbert G.
                  S~, ~. That opinion states that Oklahoma would not recognize a Mexican divorce when
                  the plaintiff does not reside in Mexico. The opinion relied on an Oklahoma Supreme
                  Court decision, Kirk  v. Kirk 238 P.2d 808 (1951). Our research reveals no subsequent decision which would overrule
                  Kirk. Therefore, Oklahoma would not recognize the M~ divorce because Donald M~ never resided
                  in Mexico.
               
               Although the divorce is invalid under Oklahoma law, Vada M~ may be estopped from denying
                  its validity. Vada M~ was notified that Donald M~ had filed for divorce and she did
                  not contest it. Further she did not appeal the divorce decree. In Kirk, discussed above, the defendant wife never knew of the divorce proceeding.
               
               It is an accepted principal of equity that a person may be precluded from attacking
                  the validity of a foreign divorce decree if, under the circumstances, it would be
                  inequitable for that person to do so. Restatement (Second) Conflict of Laws, ยง74(1971).
                  Our research has found no Oklahoma case which has decided the question of whether
                  a spouse would be estopped from denying an invalid Mexican divorce because of the
                  passage of time. Oklahoma has recognized the doctrine of estopped in connection with
                  divorce proceedings in other situations. See Martin v. Martin 511 P.2d 1097,1100 (Okla. Supreme Court, 1973); Smith et al. v. Smith 242 P.2d 436, 438 (Okla. Supreme Court, 1952).
               
               This is our opinion that Vada E. M~ would be estopped from denying the validity of
                  the Mexican divorce. Vada knew of the divorce and made no effort to contest it. Further,
                  twenty-two years have passed since the divorce and Donald has remarried. It would
                  be inequitable to allow Vada to contest it now.
