Postnuptial Agreements in Florida: Understanding the Basics

Postnuptial agreements, also known as postnups or marital agreements, are legal documents that are similar to prenuptial agreements. The main difference between the two is that prenuptial agreements are signed before the wedding, while postnuptial agreements are signed after the marriage has already taken place.

In Florida, postnuptial agreements are recognized under the Uniform Premarital Agreement Act. This act allows couples to create legal documents that outline how their property and assets will be divided in the event of a divorce or separation.

Why Consider a Postnuptial Agreement?

There are several reasons why couples may want to consider a postnuptial agreement:

1. Protecting Assets: A postnuptial agreement can be used to protect assets that were acquired before the marriage or during the course of the marriage. This can include real estate, investments, and other valuable assets.

2. Business Interests: If one or both partners own a business, a postnuptial agreement can help protect those business interests in the event of a divorce.

3. Debt Management: A postnuptial agreement can also be used to outline how debts will be managed in the event of a divorce.

4. Financial Planning: A postnuptial agreement can also be used as a tool for financial planning and estate planning.

Requirements for a Valid Postnuptial Agreement in Florida

In order for a postnuptial agreement to be valid in Florida, it must meet certain requirements:

1. The agreement must be in writing and signed by both parties.

2. Both parties must make full and complete financial disclosures.

3. The agreement must be entered into voluntarily and without coercion.

4. The agreement must be fair and reasonable at the time it is signed.

5. Both parties must have had the opportunity to consult with an attorney.

If any of these requirements are not met, the agreement may not be enforceable in court.

Enforcing a Postnuptial Agreement in Florida

If a postnuptial agreement meets all of the requirements and is properly executed, it can be enforced in court. However, it is important to note that courts may still review the agreement to ensure that it is fair and reasonable when it is being enforced.

Additionally, if one party believes that the agreement is invalid, they may challenge it in court. This can be a lengthy and expensive process, so it is important to ensure that the agreement is properly executed and meets all of the necessary requirements.


Postnuptial agreements can be a valuable tool for protecting assets and managing financial planning in a marriage. However, it is important to ensure that the agreement is properly executed, meets all of the necessary requirements, and is fair and reasonable at the time it is signed. If you are considering a postnuptial agreement in Florida, it is recommended that you consult with an experienced family law attorney to ensure that your rights are protected.
