A prenuptial agreement (“prenup” for short) is a written contract created by two people before they are married. A prenup typically lists all of the property each person owns (as well as any debts) and specifies what each person’s property rights will be after the marriage.

Contrary to popular opinion, prenups are not just for the rich. While prenups are often used to protect the assets of a wealthy fiancé, couples of more modest means are increasingly turning to them for their own purposes.
