Prenuptial and antenuptial (not anti although it seems that way) agreements are the same thing. They are different names for a document that sets out the terms of dissolution of a marriage when there is a death or divorce. If you signed one of these prior to your marriage, let me know. That document should control the terms of the dissolution of the marriage. The law has changed several times in this area and there are some technical requirements and loopholes, so it is important that a lawyer examine any premarital agreements.
