A more thorough explanation:

The Uniform Premarital Agreement Act is a law that helps make sure prenuptial agreements are consistent from state to state. This means that people who are getting married can choose a state to make their prenuptial agreement in, and the agreement will be valid in other states too. The law also covers important issues related to marriage, such as how property will be divided and who will take care of any children.

For example, let's say that John and Jane are getting married in California, but they plan to move to New York after the wedding. They want to make a prenuptial agreement to decide how their property will be divided if they ever get divorced. Thanks to the Uniform Premarital Agreement Act, they can make the agreement in California and it will still be valid in New York.

The law also treats postnuptial agreements and premarital agreements the same way. This means that if John and Jane decide to make an agreement after they get married, it will have the same requirements and principles as their prenuptial agreement.
