FLORIDA PRENUPTIAL AGREEMENT ATTORNEYS A prenuptial agreement is a contract that you sign with your future spouse that details how your assets will be divided in the event that your marriage ends in divorce. Without a prenuptial agreement, you will either have to come to an agreement with your spouse about the division of your marital assets or have a judge decide for you. Either scenario can be acrimonious, expensive, and time-consuming. For this reason, it’s advisable for anyone getting married to enter into a prenuptial agreement.
