Florida Postnuptial Agreement Overview
Florida recognizes postnuptial agreements under general contract law principles and the fiduciary duty standard between married spouses. The Florida Supreme Court addressed the enforceability of postnuptial agreements in Casto v. Casto (1987), establishing that such agreements are valid when they meet the requirements for fairness, full disclosure, and voluntary execution.
Florida is an equitable distribution state under Florida Statutes Section 61.075, where marital assets and liabilities are distributed equitably between the spouses. Without a postnup, a Florida court considers a range of statutory factors including the contribution of each spouse, the economic circumstances of each party, and the length of the marriage. A postnuptial agreement allows couples to define these terms privately.
Florida courts apply the fiduciary duty standard to postnuptial agreements, meaning spouses must deal with each other in the utmost good faith. The Casto decision established that postnups must be free from fraud, deceit, duress, coercion, or overreaching. Given Florida's large retirement community and prevalence of second marriages, postnuptial agreements are commonly used to protect inheritance rights and manage blended family finances.

Florida Postnuptial Agreement Legal Requirements
Florida postnuptial agreements must meet the Casto v. Casto standards for fairness, voluntariness, and full financial disclosure, supplemented by the fiduciary duty between spouses.
Important: Florida Execution Requirements
Florida courts apply the Casto v. Casto standard to postnuptial agreements, requiring that they be free from fraud, deceit, duress, coercion, or overreaching. Both spouses must provide full financial disclosure and act with the utmost good faith. Independent legal counsel is strongly recommended for both parties.
Formal Requirements
- Written Agreement: Florida requires the postnuptial agreement to be in writing — oral agreements between spouses are not enforceable
- Both Spouses Must Sign: The agreement must be signed by both spouses to be valid under Florida law
- Voluntary Execution: Both spouses must sign voluntarily without duress, coercion, or undue influence
- Full Financial Disclosure: Both spouses must provide complete and accurate disclosure of all assets, debts, income, and financial obligations
- Not Unconscionable: The agreement must not be so one-sided as to be unconscionable under Florida law
What Can Be Addressed
- Rights and obligations in property owned by either or both spouses
- Disposition of property upon separation, divorce, or death
- Spousal support (alimony) terms, modifications, or waivers
- Life insurance, estate planning, and inheritance provisions
- Debt allocation and responsibility for financial obligations
- Any other matter not in violation of Florida public policy or criminal law
Florida Postnup Enforceability Rules
Under the Casto v. Casto standard, Florida courts enforce postnuptial agreements that are fair, voluntary, and supported by full financial disclosure. The fiduciary duty between spouses requires the utmost good faith and fair dealing. Florida courts have generally been supportive of well-drafted postnuptial agreements, particularly those involving second marriages and blended families.
Spousal Support Waiver
Permitted — Florida courts enforce spousal support provisions in postnuptial agreements, including waivers, provided the agreement meets the Casto standards for fairness and voluntariness
Consideration Requirement
Florida does not require separate consideration for postnuptial agreements — the mutual promises within the agreement are sufficient
Unconscionability Standard
Courts evaluate unconscionability under the Casto framework, examining whether the agreement was fair when executed and whether enforcement would produce unjust results
