Whether you call it a Prenuptial Agreement, a Prenup, or a Premarital Agreement, it is a contract between you and your future spouse that determines your financial rights and obligations if your marriage ends as a result of divorce or death.
Talking about a Prenuptial Agreement helps you and your fiancé openly discuss how you and your fiancé will handle your finances during your marriage.
It is best to discuss these issues as far in advance of your wedding as possible. You do not want to be talking about who pays for what and who will have ownership of which bank account when it is time to be talking about the menu for your wedding day.
If you decide that it is too close to your wedding date to start the conversation about a Prenuptial Agreement, you can wait and agree to work on a Postnuptial Agreement. It is a similar document that is signed after you are married.
