Prenuptial and postnuptial agreements are no longer exclusive to celebrities or people with high net worth. Whether it is a young couple or a group with a high financial potential, in Florida, couples depend on such legal tools to define expectations and ensure asset preservation. Still, the question arises how legal these agreements are. The solution is in their drafting, disclosure, and implementation.
These agreements can greatly influence what a divorce will provide, whether they are signed before marriage (a prenup) or following the exchange of vows (a postnup).
Understanding Prenuptial & Postnuptial Agreements in Florida
A prenuptial agreement is a document signed before marriage that sets out how the assets, debts, and perhaps spousal support will be managed in the event of divorce. A postnuptial arrangement, on the other hand, is a signed agreement after the couple has already gotten married.
Both of them are enforceable under Florida law, however, under certain circumstances only. According to the Florida Uniform Premarital Agreement Act (UPAA), which governs prenups, these agreements must be:
- In writing
- Voluntarily signed by both parties
- Made with full and fair disclosure of financial information
Postnuptial agreements are not governed by the UPAA, but Florida courts treat them with similar scrutiny. They are enforceable under contract law, so long as both parties agreed freely, without fraud, duress, or coercion.
Why Couples Choose These Agreements
People enter such agreements for several reasons:
- To safeguard the assets acquired before marriage
- To establish what constitutes marital and non-marital property
- To forego or restrict alimony
- In order to ease the process of divorce when dividing assets
42% of U.S. adults believe prenups are a smart financial planning tool, up from just 3% in the early 2000s. Millennials are the fastest-growing group requesting prenups, especially in states like Florida, where property values and personal business interests often complicate divorces.
Enforceability in Florida Courts
Florida courts do honor prenuptial and postnuptial agreements, but enforcement depends on several factors:
1. Voluntariness
A prenup or postnup must be entered into voluntarily. If one party proves they were pressured into signing it, the agreement can be invalidated. Courts consider factors like timing, legal representation, and mental capacity.
2. Full Financial Disclosure
Both parties must fully disclose their assets and debts before signing. Failure to do so could render the agreement unenforceable. For example, if one spouse hides a business or investment account, the court may throw out the agreement.
3. Fairness at the Time of Signing
An agreement that is grossly one-sided or unconscionable may not hold up in court. Florida judges examine whether the terms were fair when the contract was signed—not just at the time of divorce.
4. Proper Execution
The agreement must be signed and in writing. Oral agreements will not be enforced, no matter how detailed or agreed-upon they were in conversation.
Statute Governing Postnuptial Agreements
Postnuptial agreements are governed under Florida contract law, rather than a specific statute like prenups. However, the principles of contract fairness and equity still apply. For a postnup to be enforceable:
- It must be supported by consideration (e.g., mutual promises or concessions)
- Each party should have the opportunity to consult independent legal counsel
- Full disclosure of assets and liabilities is crucial
While there is no singular Florida statute titled “postnuptial agreements,” case law over the years has built a strong precedent for their enforceability when properly executed.
Can a Prenup or Postnup Be Voided in Florida?
Yes, Florida courts can void a prenup or postnup under specific conditions:
- Lack of voluntary consent: If the agreement was signed under duress or coercion.
- Inadequate disclosure: If one party hide assets or failed to disclose debts.
- Unconscionability: If the agreement is so unfair it shocks the conscience of the court.
- Invalid provisions: If it tries to pre-determine child custody or support (which must be decided based on the child’s best interests at the time of divorce).
For instance, a prenup that states one parent will receive full custody, regardless of circumstances, will likely be rejected.
Florida Courts’ Current Stance
Over the past decade, Florida courts have increasingly favored upholding prenups and postnups when all legal standards are met. However, every situation is unique. Judges maintain discretion and carefully analyze agreements, especially those that appear one-sided or where there is a significant power imbalance between spouses.
Final Thoughts
Prenuptial and postnuptial agreements can bring clarity, protection, and peace of mind to both spouses. But for these contracts to hold up in Florida courts, they must be entered into freely, fairly, and transparently. From disclosure and fairness to proper execution, the law prioritizes both parties’ rights.
