(a) An individual who is divorced from the decedent or whose marriage to the decedent has been annulled is not a surviving spouse unless, by virtue of a subsequent marriage, the individual is married to the decedent at the time of death. A decree of separate maintenance that does not terminate the status of husband and wife is not a divorce for purposes of this section.

(b) For purposes of Parts 1, 2, 3, and 4 of Article 2 [Sections 62-2-101 et seq., 62-2-201 et seq., 62-2-301 et seq., and 62-2-401 et seq.] and of Section 62-3-203, a surviving spouse does not include:

(1) an individual who obtains or consents to a final decree or judgment of divorce from the decedent or an annulment of their marriage, which decree or judgment is not recognized as valid in this State, unless they subsequently participate in a marriage ceremony purporting to marry each to the other, or live together as husband and wife at the time of the decedent’s death;

(2) an individual who, following an invalid decree or judgment of divorce or annulment obtained by the decedent, participates in a marriage ceremony with a third person;

(3) an individual who was a party to a valid proceeding concluded by an order purporting to terminate all marital property rights or confirming equitable distribution between spouses unless they are living together as husband and wife at the time of the decedent’s death; or

(4) an individual claiming to be a common law spouse who has not been established to be a common law spouse by an adjudication commenced before the death of the decedent or within the later of eight months after the death of the decedent or six months after the initial appointment of a personal representative; if the action is commenced after the death of the decedent, proof must be by clear and convincing evidence.

(c) A divorce or annulment is not final until signed by the court and filed in the office of the clerk of court.
