This memorandum responds to your request for our opinion about the effect of a court
                  order setting aside a divorce decree under Oklahoma law. Specifically, you ,asked
                  the following questions:
               
               1. Does a state district court have the authority to set aside a divorce?
               2. What is the effect of an order setting aside a divorce decree?
               3. Is claimant Lu A. F~ considered to have been lawfully divorced from August 1998
                  through December 1998?
               
               4. Is claimant Lu A. F~ entitled to widow's benefits on the record of her first husband,
                  Richard F~, for any time prior to February 1999?
               
               5. Was Lu A. F~ lawfully married to William M~, her second husband, at the time of
                  his death and entitled to the lump sum death payment on his record?
               
               Based on our review of applicable State laws, it is our opinion that the District
                  Court of Mayes County, Oklahoma, had the authority to set aside the August 1998 divorce
                  decree of Lu A. F~ and William M~ and that the order vacating the divorce was effective
                  the date it was rendered. Because the order vacating the divorce decree stated that
                  the divorce was set aside, vacated, and held for naught, the divorce was reordered
                  a nullity, as if the parties had never been divorced, Because Lu A. F~ and William
                  M~ were essentially never divorced, Lu A. F~ did not qualify for widow's benefits
                  on Richard F~'s record. However, Lu A. F~ is entitled to the lump sum death payment
                  on the record of William M~ because she was lawfully married to him at the time of
                  his death and living in the same household with him at the time of his death.
               
               In June 1958, Lu A. B~ married Richard F~, and the two remained married until Richard
                  F~'s death in June 1977. In November 1980, Lu A. F~ married William M~. In January
                  1989, Lu A. F~ and M~ divorced. Pursuant to a court order, the divorce was Set aside
                  in March 1989. Lu A. F~ and M~ remained married until August 1998, when they divorced
                  a second time. In September 1998, Lu A. F~, age 60, applied for aged widow's benefits
                  on the record of her first husband, Richard F~. In December 1998, Lu A. F~ and M~
                  agreed to set aside their August 1998 divorce decree and the District Court for Mayes
                  County, Oklahoma vacated the August 1998 divorce decree. In February 1999, William
                  M~ died.
               
               Your first question asks whether the District Court has the authority to set aside
                  a divorce decree. Oklahoma law provides two ways to vacate or set aside a court order.
                  First, the parties can agree to set aside a divorce decree under the Oklahoma Marriage
                  and Family Code. Okla. Stat. Ann. Tit. 43 §133 provides:
               
               When a decree of divorce has been issued by a district or superior court said court
                  is hereby authorized to dissolve said decree at any future time, in or out of the
                  term wherein the decree was granted, provided that both parties to the divorce action
                  file a petition, signed by both parties, asking that said decree be set aside and
                  held for naught. And further provided that both parties seeking to have the decree
                  set aside shall make proof to the court that neither one has married a third party
                  during the time since the issuance of the decree of divorce.
               
               Second, under the Oklahoma Code of Civil Procedure, a district court can vacate or
                  modify its own judgments or orders when certain circumstances exist, such as fraud
                  by a party, or mistake, neglect, or omission by the clerk. Okla. Star. Ann. lit. 12,
                  §1031. Oklahoma law further provides that a court may correct, open modify or vacate
                  a judgment or a party can file a motion to vacate within thirty days after a judgment,
                  decree, or appealable order is filed. Okla. Star. Ann. Tit. 12 §1031.1
               
               The information shows that in December 1998 the District Court of Mayes County, Oklahoma
                  set aside the above-mentioned August l1, 1998, divorce decree. Under Title 43, §133
                  of the Oklahoma Marriage and Family Code, the District Court had the authority to
                  do this. Because the Court had the authority to set aside the divorce decree under
                  Okla. Star. Ann. Tit. 43 §133, and because there is no evidence that grounds were
                  sufficient for the parties to proceed under Title 12 §1031, or §1031.1, no further
                  discussion of Title 12 § 1031 or § 1031.1 is necessary.
               
               The second question you asked involves the effect of an order setting aside the divorce
                  decree. Title 43 §133 of the Oklahoma Marriage and Family Code states that upon agreement
                  of the parties, a divorce decree can be set aside and held for naught. The December
                  1998 order which set aside the divorce decree stated, "That. the decree of divorce
                  filed on the 11th day of August, 1998 shall be and hereby is set aside, vacated, and
                  held for naught, the relationship of husband and wife is hereby reinstated between
                  the parties hereto." The term to vacate means to "annul; to set aside; to cancel or
                  rescind; to render an act void." Meekins v. Department of Institutions, Social and Rehabilitative Services, 554 P.2d 872, 875 (Okla. Ct. App. 1976)(citing
                  Black's Law Dictionary.). Vacation is a remedy used when the parties believe some
                  error makes the continued existence of an order undesirable. Id. In Meekins, the court found that to vacate something is to destroy it, to eliminate it, to render
                  it a nullity. When Lu A F~ and William M~ agreed to vacate the divorce decree, they
                  intended to render the divorce a nullity, as if it never occurred. Therefore, Lu A.
                  F~ and William M~ were never divorced. Based on the caselaw defining the term vacate,
                  our opinion is that the order setting aside the divorce decree rendered the August
                  1998 divorce a nullity, so that Lu A. F~ and William M~ were effectively never divorced.
                  See also, In the Matter of the Estate of Pugh, 281 P.2d 937, 939 (OK 1955) (Joint petition and request of both parties vacated
                  the divorce decree and restored them to their former marital status and restored the
                  property rights between them as they existed prior to the granting of the divorce).
                  In response to your third question therefore, Lu A. F~ was not lawfully divorced from
                  William M~ from August 1998 through December 1998.
               
               You also asked whether there had been ,my subsequent changes to legal precedents on
                  this matter since the early 1970's. The information you submitted refers to Okla.
                  Stat. Ann. Tit. 12 § 1031, the provision under the code of civil procedure which provides
                  for vacation and modification of court orders. This law is still in effect. However,
                  as noted above, this law does not apply in this ease because the parties have not
                  alleged fraud, or mistake by the clerk, but instead wish to set aside the divorce
                  decree by agreement, as contemplated by Title 43 of the Oklahoma Marriage and Family
                  Code. The material you submitted also referred to Okla. Stat. Ann. Tit. 12 §1288.
                  In 1989, this statute was renumbered as part of Title 43 of the Oklahoma Marriage
                  and Family Code.
               
               Your next question asks whether Lu A. F~ is entitled to widow's insurance benefits
                  on the record of her first husband, Richard F~, for any of the months prior to February
                  1999. Once the District Court issued an order vacating the August 1998 divorce between
                  Lu A. F~ and William M~, the effect of the order was to render the divorce a nullity.
                  If the divorce is considered a nullity, Lu A. F~ and William M~ were effectively never
                  divorced. If Lu A. Fire was never divorced from William M~. she could not quality
                  as F~'s widow for insurance benefits under the Social Security Act (the Act). Entitlement
                  to "widow's insurance benefits" is governed by the Act which provides, in pertinent
                  part:
               
               "(e)(1) The widow (as defined in section 216(c)) and every surviving divorced wife
                  (as defined in section 216(d)) of an individual who died a fully insured individual,
                  if such widow or such surviving divorced wife-
               
               (A) is not married (B)(i) has attained age 60, or (ii) has attained age 50 but has
                  not attained age 60 and is under a disability (as defined in section 223(d) which
                  began before the end of the period specified in paragraph (4) (C)(i) has filed application
                  for widow's insurance benefits ... and, (D) is not entitled to old-age insurance benefits
                  or is entitled to old age insurance benefits each of which is less than the primary
                  insurance amount as determined after application of subparagraphs (B) and (c) of paragraph
                  (2)) of such deceased Individual shall be entitled to a widow's insurance benefit
                  ..... "42 U.S.C. §402(e)(I)(emphasis added).
               
               By operation of the order setting aside the divorce decree, Lu A. F~ was not divorced
                  from, but married to William M~ at the time of her application for benefits in September
                  1998. Therefore, she cannot qualify for widow's benefits on the record of Richard
                  Fire, her first husband, because she had remarried by the time she had come to claim
                  them.
               
               Finally, you ask whether Lu A. F~ is entitled to a lump sum death payment on the record
                  of William M~. The Social Security Act provides two ways for a widow to establish
                  entitlement to a "lump sum death payment." First, a widow can get a lump sum death
                  payment if she was living in the same household with the deceased at the time the
                  death of the insured. 42 U.S.C. §402(i). Second, a widow can receive a lump sum death
                  payment if she is entitled to widow's benefits under subsection (e) of the Act. 42
                  U.S.C. §402(i)(1). In the application for the lump sum death payment, Lu A. F~ stated
                  that she was living in the same household as William M~ at the time of his death.
                  Because Lu A. F~ had been living in the same household at the time of William M~'s
                  death, Lu A. F~ would be entitled to the lump sum death payment under §402(i) of the
                  Act. Therefore, it is our opinion that Lu A. F~ is entitled to the lump sum death
                  benefit on the record of William M~,
