A marriage contract is governed by which of the following?

A marriage contract is primarily governed by state law. This is because marriage, as a legal institution, is regulated at the state level in the United States. Each state has its own laws concerning the formation, duration, and dissolution of marriage, as well as the rights and responsibilities that come with it. State statutes outline the requirements for obtaining a marriage license, the legal age for marriage, and the grounds for divorce, among other things.

While religious beliefs and local regulations might influence marriage practices or the ceremonies themselves, they do not typically dictate the legal rights and responsibilities outlined in a marriage contract. Furthermore, the federal government does provide some overarching laws regarding marriage, particularly in areas like tax filing or equality rights, but it does not govern marriage contracts directly. Therefore, the accurate authority governing marriage contracts is the state.
