Marital contracts are an excellent option for preserving your marriage because they can be signed before and during your marriage to your spouse. Premarital or prenuptial agreements are agreements made between spouses that will become effective once marriage occurs. Both parties must sign these. Generally, prenuptial agreements cover things like property rights and obligations. Prenup agreements usually seek to protect what will happen to these assets if separation, death, or divorce occurs. In addition, premarital agreements can include provisions for making wills, trusts, or other arrangements. Basically, pretty much anything that a couple could conceivably fight about during a marriage can be pre-decided in a prenuptial agreement. Even deciding whom the pets will go to in a cohabitation agreement if a separation occurs can be determined. A postnuptial agreement can be signed after you and your spouse is already married. These contracts are used to either establish agreements or change those initially established under a prenuptial agreement.
