Prenuptial agreements are contracts created by couples who want to determine how their assets will be divided if they ever get divorced. Prenuptial agreements are executed before the date of marriage. It is important that excessive pressure is not exerted to obtain the signature of either party on the prenuptial agreement, or it may render the agreement invalid. It is also important to execute the prenup well before the date of the marriage to avoid a claim of duress.
Postnuptial agreements are contracts created by couples executed after the date of marriage. Similar to a prenuptial agreement, a postnuptial agreement establishes how assets will be divided in the event of a divorce or legal separation and the amount (if any) of spousal support that one spouse will pay to the other if the marriage ends.
