When it comes to a legal agreement between couples prior to marriage, often referred to as a "marriage settlement," there are several synonyms. Some of these include prenuptial agreement (often shortened to "prenup"), premarital agreement, matrimonial agreement, and antenuptial agreement. Regardless of the term used, the purpose of such an agreement remains the same: to outline the division of assets and property, and establish provisions for spousal support in the event of divorce. These agreements can be particularly important for individuals with substantial assets or for couples entering marriage with children from previous relationships.
