Postnuptial agreements have gained popularity among married couples in recent years. A postnuptial agreement refers to a legal agreement between two parties that is entered into after marriage and deals with a variety of matters such as the division of assets, spousal support, and custody of children. Synonyms for the term 'postnuptial' include 'midnuptial,' 'postmarital,' and 'post-wedding.' These agreements are essential for couples with assets, liabilities, or children. They provide a written document that clarifies the rights, obligations, and expectations of each spouse. Moreover, they help couples avoid costly and time-consuming legal battles in case of an eventual separation or divorce.
