Prenuptial Agreements, sometimes referred to as “Prenups” are employed for at least two distinct and separate purposes. First, they define what will occur should a marriage be dissolved. Secondly, they define what will occur should one marriage partner predecease the other while married. Some agreements incorporate one of these purposes and some both. A postnuptial agreement is a very similar document but it is executed after the marriage takes place as opposed to before the marriage.
