Prenuptial agreements (entered into prior to marriage) and postnuptial agreements (entered into after marriage) are legally enforceable contracts between spouses-to-be (prenups) and spouses in an intact marriage (postnups).
Full disclosure of the assets of both spouses is required. Marriage alone is considered adequate consideration for a prenup, but postnups require that there be other, legally sufficient consideration. The content of prenups and postnups can vary widely, but commonly includes provisions for division of property and spousal support in the event of divorce or the death of one party. However, they generally do not regulate issues related to the children of the marriage.
