What is the fate of a man's wife who was arrested five years ago, and whose family was informed of his death five days after his arrest, without knowing his true fate, and is she entitled to marry after obtaining a death certificate for him?

If there is clear evidence of a man's death, even if it is reported by a single trustworthy individual, his wife observes the waiting period (iddah) of widowhood and can remarry after its completion. However, if the news of death is unreliable, coming from untrustworthy informants, his death is not confirmed, and the wife remains bound to him until she is certain of his death, as the default assumption is the continuation of life. If the wife is harmed by her husband's prolonged absence, she may refer the matter to a judge to separate them.
