Prenuptial Agreements: Drafting Enforceable Provisions and Common Reasons for Invalidity

By Marquez Law

Prenuptial agreements are not limited to wealthy couples. They can clarify how you and your future spouse will own, manage, and divide property and address rights if the marriage ends or either spouse dies. A useful agreement must reflect the parties’ intentions while complying with Florida law. Unclear provisions, incomplete financial information, or evidence of pressure can create an enforcement dispute.

At Marquez’ Law, I prepare and review prenuptial agreements based on each client’s finances and goals. I have offices in Orlando and West Palm Beach, Florida, and serve Orange, Osceola, Seminole, Palm Beach, and Broward counties. Contact me today to discuss your agreement.

What Makes a Prenuptial Agreement Enforceable?

Florida’s Uniform Premarital Agreement Act applies to agreements between prospective spouses made in contemplation of marriage and intended to take effect upon marriage. The statute requires the agreement to be in writing and signed by both parties. The marriage itself supplies the required consideration.

Florida’s statute does not generally require witnesses, notarization, or separate attorneys. Additional formalities may be prudent, and provisions affecting rights at death may implicate probate requirements. Independent advice can also help demonstrate that the agreement was understood and voluntarily signed.

Important drafting and execution practices include:

  • Complete financial information: Each party should provide fair and reasonable disclosure of assets, income, business interests, and financial obligations. Attached schedules can document the disclosure.

  • Voluntary execution: Neither person should sign because of fraud, duress, coercion, or overreaching. Starting early allows sufficient time for disclosure, review, and negotiation.

  • Clear written provisions: The agreement should identify covered property and explain the parties’ rights without relying on vague or contradictory language.

  • Separate review: Although not an absolute statutory requirement, separate attorneys can explain how the terms affect each person and recommend revisions.

  • Proper signatures and records: Both parties must sign the agreement and should retain complete copies and the associated disclosures.

No particular number of weeks or months before the wedding guarantees enforceability. Signing shortly before the ceremony is not automatically invalid, but timing and surrounding conduct may become relevant to voluntariness.

What May a Prenuptial Agreement Cover?

Florida law permits prospective spouses to address a broad range of financial and personal matters. An agreement may govern:

  • Rights and obligations concerning property owned before or acquired during the marriage itself.

  • Management, sale, transfer, use, or disposition of property.

  • Distribution of property upon separation, divorce, death, or another specifically identified event.

  • Establishment, modification, waiver, or elimination of spousal support.

  • Wills, trusts, and other arrangements used to carry out the agreement.

  • Ownership and disposition of life-insurance death benefits.

  • The law governing interpretation of the agreement.

  • Other personal rights and obligations that do not violate Florida public policy or a criminal law.

A prenuptial agreement does not necessarily bind a third-party creditor that was not part of the contract. It also cannot adversely affect a child’s right to support. Parenting plans and time-sharing decisions remain subject to the child’s best interests when the issue arises.

I draft prenuptial and postnuptial agreements with provisions tailored to the parties’ property, businesses, estate-planning concerns, and potential support obligations.

Common Reasons for Invalidity

The person challenging enforcement bears the burden of proving a statutory ground. Under Florida law, a premarital agreement may be unenforceable if that person proves:

  • The agreement was not signed voluntarily.

  • The agreement resulted from fraud, duress, coercion, or overreaching.

  • The agreement was unconscionable when signed, and the required financial-disclosure conditions were not satisfied.

For the third ground, the challenging party must establish that the agreement was unconscionable when executed and, before signing, that the party did not receive fair and reasonable financial disclosure, did not voluntarily and expressly waive further disclosure in writing, and lacked adequate knowledge of the other party’s property or financial obligations.

This standard is more specific than asking whether the agreement later appears unequal. A substantial difference in wealth or an uneven allocation of property does not, by itself, automatically invalidate the agreement. The court evaluates unconscionability as a matter of law under the statutory test.

Evidence of voluntariness may include timing, access to legal advice, opportunity to negotiate, threats to cancel the wedding, and the circumstances surrounding execution. No single fact necessarily controls.

Provisions a Court May Decline to Enforce

Some provisions may be restricted even if the rest of the agreement remains enforceable. A premarital agreement cannot waive or reduce a child’s right to support. Although parents may state their intentions regarding parenting, they cannot legally bind a future court to custody or time-sharing terms that do not serve the child’s best interests. If an agreement modifies or eliminates spousal support and that provision would make one party eligible for public assistance at separation or divorce, the court may require support to the extent necessary to avoid that eligibility.

Terms that violate public policy or a law imposing criminal penalties are also impermissible. Whether an unenforceable term affects the entire agreement may depend on the wording, applicable law, and whether the agreement contains an effective severability provision.

Protecting Property and Financial Expectations

A prenuptial agreement may identify separate property, define how future income or appreciation will be treated, and establish rules for jointly acquired property. It may also address business interests, real estate, retirement assets, inheritances, and responsibility between the spouses for specified obligations.

The agreement does not prevent creditor disputes or replace estate-planning documents. Later conduct, such as commingling funds or changing title, may also affect property. Coordinating deeds, beneficiary designations, wills, trusts, and business documents can reduce inconsistencies.

After marriage, the parties may amend, revoke, or abandon a premarital agreement only through a written agreement signed by both. Because circumstances and assets change, periodic review may help confirm that related documents remain consistent with the agreement.

A carefully prepared prenuptial agreement can establish financial expectations and reduce uncertainty, but enforceability depends on the language, disclosure, execution, and surrounding circumstances.
