The following shall be considered dead for all purposes including the division of the estate among the heirs:
(1) A person on board a vessel lost during a sea voyage, or an aircraft which is missing, who has not been heard of for four [(4)] years since the loss of the vessel or aircraft;
(2) A member of the armed forces who has taken part in armed hostilities, and has been missing for four [(4)] years;
(3) A person who has been in danger of death under other circumstances and whose existence has not been known for four [(4)] years; and
(4) If a married person has been absent for four [(4)] consecutive years, the spouse present may contract a subsequent marriage if he or she has a well-founded belief that the absent spouse is already dead. In case of disappearance, where there is a danger of death[, under] the circumstances hereinabove provided, an absence of only two [(2)] years shall be sufficient for the purpose of contracting a subsequent marriage. However, in any case, before marrying again, the spouse present must institute summary proceeding[s] as provided in the Family Code and in the rules for declaration of presumptive death of the absentee, without prejudice to the effect of reappearance of the absent spouse[;]
