The dowry is due to the wife upon a valid marriage contract (art. 52), and there is no minimum or maximum limit (art. 53). Anything lawfully capable of being an obligation may serve as dowry, whether money, work, or a benefit, so long as it does not conflict with the husband's authority (art. 54). If no dowry is named or the naming is invalid, a dowry of the like (mahr al-mithl) is due (art. 55).
The full dowry is confirmed by actual consummation, by valid seclusion (khalwa), or by the death of either spouse (art. 61).
If the wife is divorced before consummation or valid seclusion, she is entitled to half the named dowry, and if she received more than half he may recover the excess (art. 63). If no dowry was named, she is entitled to a gift (mut'a) set by the judge, not exceeding half of a dowry of the like (art. 64). The whole dowry or the gift is forfeited if the separation occurs due to the wife before consummation or valid seclusion (art. 65).
