Premarital agreements also known as prenuptial agreements, also apply to family law. Couples structure their financial affairs in a prenuptial agreement if they want to manage their assets apart from their spouse or provide for children from a previous marriage, or if they have different levels of assets or income. Prenuptial agreements are a good way to protect spouses from liability for the other’s debts, and it may also minimize tension if a marriage is later terminated, by knowing in advance the financial rights of each party.
