Your memorandum of September 1, 1982, requested our opinion as to whether Louella
                  W~ meets the definition of legal widow of S.T. W~, the deceased number holder who
                  died on July 6, 1972, while domiciled in Mississippi.
               
               The facts as contained in the file indicate that in July 1972 Orean W~ was awarded
                  mother's benefits based on her February 20, 1953, ceremonial marriage to S.T. W~ in
                  Lawrence County, Mississippi. Mr. W~ and Orean were living together when he died;
                  they had thirteen children. On her application for mother's benefits, Orean stated
                  that the deceased wage earner (DWE) had a prior marriage to Louella which ended in
                  divorce several years before his marriage to Orean.
               
               On May 17, 1982, Louella W~ filed an application for widow's benefits and submitted
                  proof of her ceremonial marriage to S.T. W~ on January 12, 1941, in Lawrence County,
                  Mississippi. She stated that she and Mr. W~ separated in 1942 and she thought Mr.
                  W~ had secured a divorce; however, when she searched the Jefferson Davis County, Mississippi,
                  records, a divorce decree could not be located.
               
               Louella W~ stated that she lived in Jefferson Davis County and in Lawrence County
                  in Mississippi. Orean W~ and S.T. W~ 's sister, Pauline P~, stated that Mr. W~ lived
                  in New Hebron, Lawrence County, from his birth until 1958 when he moved to Hattiesburg,
                  Forrest County, Mississippi. No other places of residence are alleged. The number
                  holder's mailing address was shown as a rural route in Hattiesburg, Forrest County,
                  Mississippi; however, his place of residence at death was shown as Lamar County, Mississippi.
               
               A search of the court records for Lawrence County, Lamar County, Jefferson Davis County,
                  and Forrest County for the years 1941 through 1972 revealed no divorce for S.T. and
                  Louella W~. A record was located in Jefferson Davis County showing that S.T. W~ filed
                  a divorce action against Louella W~ in May 1949. The cause (Case No. 3323) was dismissed
                  without prejudice on May 22, 1950. No other record could be found.
               
               Your memo queries whether, under Mississippi law, the presumption of the validity
                  of the last marriage is rebutted by the finding that no divorce occurred at any place
                  of residence on either Louella W~ or the number holder during their life times; or,
                  whether the ruling in Alma L. Blackwell v. Flemming, (U.S. District Court, Southern District of Mississippi, CCH 14,118 (5/01/61)), prevents
                  a rebuttal of said presumption because of the possibilities of error on the part of
                  officials in recording all proceedings or in searching the records, or of a refutation
                  of the certificate of the preacher who performed the number holder's first marriage.
               
               It is our opinion that the ruling in Blackwell does not preclude a rebuttal of the presumption of the validity of the last marriage.
                  This presumption is very strong and can be rebutted only by proof so cogent and conclusive
                  as to fairly preclude any other result; however, the holding in Blackwell appears to have been based on a finding that the first wife was estopped by her conduct
                  from rebutting the presumption of the validity of the last marriage. Blackwell is not, however, characteristic of the holdings in cases in which the validity of
                  the last marriage is at issue absent reasons for estoppel.
               
               In the 1980 case of Smith v. Weir, 387 So.2d 761, the Mississippi Supreme Court addressed the presumption of the validity
                  of the last marriage and considered the degree of proof necessary to rebut the presumption,
                  at 763-764:
               
               Where there is proof of a marriage ceremony, the law will presume the capacity of
                  the parties, consent of the parties, and all essentials to the validity of the marriage.
                  The presumption was early recognized by this court in Hull v. Rawls, 27 Miss. 471 (1854), and has been consistently applied ever since.
               
               The rule of law was perhaps best stated in Anderson-Tully Co. v. Wilson, 221 Miss.
                  656, 74 So.2d 735' (1954) as follows:
               
               It is well-established that when a person has entered into several successive marriages,
                  a presumption arises in favor of the validity of the second or last marriage. And
                  this presumption of validity is applicable to a subsequent common-law marriage, as
                  well as to a subsequent ceremonial marriage. A~., 14 A.L.R.2d 7, 19; 55 C.J.S. Marriage
                  §43, pp. 887-892, 896. A subsequent marriage in fact raises the presumption that a
                  former marriage has been terminated by divorce or by the death of a prior spouse.
                  These presumptions are based upon public policy. The burden of adducing evidence to
                  the contrary rests on the party who attacks it. 55 C.J.S. [Marriage, §43], pp. 890-891.
                  Of course this presumption can be rebutted by evidence excluding the possibility of
                  a divorce or death of a prior spouse, 14 A.L.R.2d 45, but that burden of proof is
                  a difficult one: "It has been declared that, an existing marriage being shown, the
                  presumption of its validity is so strong that proof of a former subsisting marriage,
                  in order to be sufficient to overcome this presumption, must be so cogent and conclusive
                  as to fairly preclude any other result." (221 Miss. at 662, 74 So.2d at 737).
               
               In Pigford Bros. Construction Co. v. Evans, 225 Miss. 411, 83 So.2d 622 (1955) ... the court in considering the kind of proof
                  necessary to overcome the presumption stated:
               
               The practical course of proof in such a case would be to show where each party to
                  the prior marriage had resided up to the time of the second marriage, and then to
                  procure from the clerk of the proper court in each such county a certificate of search
                  showing that no divorce or annulment had been granted by the court of which he is
                  clerk. (225 Miss. at 421, 83 So.2d at 625).
               
               See also, In re Estate of Erwin, 317 So.2d 55 (1975); Ramphrey v. Ramphrey, 243 Miss. 184, 137 So.2d 902 (1962). We consider the Smith v.  Weir, supra, holding to be controlling as to the degree of proof necessary to rebut the
                  presumption of the validity of the last marriage in Mississippi.
               
               The facts in the record indicate that subsequent to their 1941 marriage and prior
                  to the wage earner's later marriage in 1953, Louella W~ lived in Lawrence and Jefferson
                  Davis Counties. During the same time period, the wage earner lived in Lawrence, Forrest,
                  and Lamar Counties. Apparently, at no point in time during the period in question,
                  was the whereabouts of either Louella or S.T. W~ unknown. A search of the records
                  in Lawrence, Lamar, Jefferson Davis and Forrest Counties has revealed no final divorce.
                  It is noted that the strong suggestion of the court was that it was best to procure
                  certificates of search showing that no divorce or annulment was granted; however,
                  in this claim, report of record searches would appear to be in compliance with the
                  court's guidelines.
               
               Nonetheless, we do not find that Louella W~ is entitled to benefits on the account
                  of S.T. W~. Although we concluded that Louella W~ has produced evidence sufficient
                  to rebut the presumption of the validity of the last marriage, we further conclude
                  that Louella W~ is estopped from asserting her claim under the Mississippi Supreme
                  Court's holding in Tillman v. Williams, 403 So.2d 880 (1981). In Tillmann the court did not apply the doctrine of estoppel to prevent a husband from inheriting
                  from his wife even though they had separated 15 to 20 years before the wife's death
                  and the husband had moved his abode to an adjoining county. The court declined to
                  apply estoppel against the husband's petition inasmuch as there was no evidence of
                  any attempt of remarriage or disclaimer of marriage by either party during the years
                  of separation or that either attempted to obtain a divorce.
               
               The Tillman court clarified earlier holdings made in Walker v. Mathews, 191 Miss. 489, 3 So.2d 820 (1941) and In Re Marshall's Will, 243 Miss. 472, 138 So.2d 482 (1962), where there appeared a sentence indicating
                  that "desertion or abandonment is held to estop a spouse from inheriting from the
                  other." The Tillman court noted that the Mississippi legislature had not seen fit to enact any legislation
                  on the abandonment question, therefore, inheritance statutes were to be strictly construed
                  absent a clear desertion and abandonment of the marriage relation.
               
               In Walker, supra, the surviving wife had engaged in a marriage ceremony with another man, and
                  her deceased husband also had married another. There was a clear abandonment of the
                  marriage relation.
               
               In Rowell v. Rowell, 251 Miss. 472, 170 So.2d 267 (1964), the court held that even an adulterous affair
                  did not amount to desertion "in the absence of a statute or showing of a bigamous
                  marriage."
               
               In Baugh v. Brimage, 242 Miss. 459, 135 So.2d 701 (1961), a surviving husband was held estopped to inherit
                  from his deceased wife's estate when he had entered into a bigamous marriage and was
                  living with still another woman with whom he had several children.
               
               In Re Marshall's Will, supra, the surviving wife lived with various men after leaving her husband. Furthermore,
                  the husband, prior to his death, had married another woman. The abandonment of the
                  marriage relationship was clear.
               
               It is our opinion that the assertions contained in the decedent's 1949 Bill for Divorce
                  to the effect that Louella had deserted him in 1943 and Louella's statement that she
                  thought they were divorced would tend to indicate that Louella W~ presumed that she
                  was single and had abandoned the marriage relation. On the basis of her abandonment
                  of the marriage relation you would be warranted in finding that Louella W~ is estopped
                  from asserting her claim as the widow of S.T. W~. If, however, Louella W~ were able
                  to produce evidence tending to indicate that she had not abandoned the marriage relation
                  (for example, records showing her status as married, records indicating S.T. W~ as
                  her husband, representation to third parties that Louella was currently married to
                  S.T. W~) she then would not be estopped from asserting her claim as the widow of S.T.
                  W~.
