Premarital or postmarital agreements are generally contracts that persons enter into in contemplation of marriage or after marriage, and which establish the property and support rights of the persons during the marriage and in the event of divorce. Practically speaking, these agreements accomplish three objectives. First, they set forth what property each person is bringing into the marriage (which is characterized as separate property). Second, they determine how property acquired during the marriage is characterized. And third, the parties can make an agreement with regard to the issue of spousal support.
