What Should Be in a Prenup in Florida? Complete 2026 Checklist

A Florida prenuptial agreement must be in writing, signed by both parties, and executed voluntarily with fair financial disclosure to be enforceable under Fla. Stat. § 61.079. Florida adopted the Uniform Premarital Agreement Act (UPAA) effective October 1, 2007, establishing clear requirements for what couples can include in their prenup. The agreement becomes effective upon marriage and can address property rights, alimony, debt allocation, business interests, and estate planning, but cannot determine child custody or child support, which remain subject to court determination under Fla. Stat. § 61.13.

Key Facts: Florida Prenuptial Agreements

What to Include in a Prenup in Florida: Essential Clauses

Florida law permits couples to address eight categories of rights in a prenuptial agreement, including property division, alimony, estate planning, and any other matter not violating public policy or criminal law. Under Fla. Stat. § 61.079(3), parties can contract for the rights and obligations of each spouse in any property, regardless of when or where acquired. The statute explicitly allows couples to establish, modify, waive, or eliminate spousal support, making alimony provisions among the most common prenup clauses in Florida.

Property Division Provisions

Florida prenuptial agreements should clearly define what constitutes separate property versus marital property, overriding default equitable distribution rules under Fla. Stat. § 61.075. Without a prenup, Florida courts presume equal distribution of marital assets, which includes all property acquired during marriage, retirement benefits accrued during marriage, and any appreciation of nonmarital assets resulting from marital efforts. A prenup allows couples to designate specific assets as separate property regardless of when acquired or how titled.

Key property clauses to include:

• Identification of all premarital assets with current valuations
• Classification of future acquisitions as marital or separate property
• Treatment of property appreciation during marriage
• Protection against commingling of separate assets
• Real estate ownership and disposition rights
• Vehicle, bank account, and investment classifications
• Inheritance and gift treatment during marriage

Alimony and Spousal Support Terms

Florida couples can waive, limit, or guarantee alimony in a prenuptial agreement, making spousal support one of the most negotiated provisions. Under the 2023 alimony reform (SB 1416), Florida eliminated permanent alimony and capped durational alimony at 35% of the difference between the parties net incomes. A prenup supersedes these statutory guidelines when properly executed. Courts honor alimony waivers unless the waiving spouse would become dependent on the state, or there is proof of duress or fraud during signing.

Common alimony structures in Florida prenups include:

• Complete waiver of all spousal support rights
• Guaranteed minimum payment amounts (for example, $20,000 lump sum upon divorce)
• Scaled approach based on marriage duration (no alimony if marriage lasts fewer than 5 years, formula-based support for longer marriages)
• Cost-of-living adjustments for long-term marriages
• Waiver of durational alimony while preserving bridge-the-gap support

Important limitation: Florida courts have held that waivers of temporary alimony during the divorce process may violate public policy and be unenforceable. Temporary support remains within the court's discretion during dissolution proceedings.

Debt Allocation and Liability Protection

Florida prenuptial agreements can allocate responsibility for debts brought into the marriage and those incurred during the marriage. Under equitable distribution principles, marital debts are typically divided between spouses upon divorce. A prenup allows couples to specify that each party remains solely responsible for their premarital debts, including student loans (average $32,000 nationally), credit card balances, vehicle loans, and other financial obligations. The agreement should address how new debts incurred during marriage will be handled.

Debt provisions should specify:

• Premarital debt responsibility for each party
• Student loan allocation and payment obligations
• Credit card debt treatment during marriage
• Mortgage and home equity loan responsibilities
• Business debt protection for non-owner spouse
• Tax liability allocation and indemnification

Business Interest Protection

Entrepreneurs and business owners should include comprehensive business protection clauses in their Florida prenup. Under the 2024 amendments to Fla. Stat. § 61.075, marital interests in a closely held business are now specifically defined as marital assets, and enterprise goodwill must be distributed between parties. Without a prenup, business appreciation during marriage becomes subject to equitable distribution, potentially forcing a sale or buyout to satisfy a former spouse's claim.

Business protection provisions should address:

• Classification of the business as separate property
• Treatment of business growth and appreciation during marriage
• Exclusion of enterprise and personal goodwill from division
• Protection of business partners from divorce claims
• Spouse's waiver of any management rights or ownership interest
• Buyout provisions if business interest is subject to division
• Valuation methodology for business assets

Retirement Account Protection

Retirement accounts are vulnerable in Florida divorce unless protected by a prenuptial agreement. Under Fla. Stat. § 61.075, vested and nonvested retirement benefits accrued during marriage constitute marital property subject to equitable distribution. Without a prenup, courts typically divide the marital portion using the coverture fraction method, requiring a Qualified Domestic Relations Order (QDRO) for 401(k)s, pensions, and similar qualified plans. A prenup can state that all retirement contributions remain the separate property of the account holder, eliminating the need for a QDRO.

Retirement provisions should cover:

• 401(k) and pension account classification as separate property
• IRA and Roth IRA treatment (note: QDROs do not apply to IRAs)
• Employer stock options and restricted stock units
• Deferred compensation plans
• Social Security benefits (cannot be waived by contract)
• Military retirement benefits
• Compensation for waiving retirement claims through other assets

Life Insurance and Beneficiary Designations

Florida prenuptial agreements can require spouses to maintain life insurance policies with specific beneficiaries, even after divorce. Under Fla. Stat. § 61.079(3)(d), parties can contract regarding the ownership, purchase, and disposition of life insurance policies. This is particularly important for couples with children from prior relationships, as it ensures death benefits pass to intended heirs rather than being subject to statutory elective share claims.

Life insurance clauses should specify:

• Required policy amounts and coverage terms
• Beneficiary designation requirements during marriage
• Changes to beneficiaries upon divorce
• Prohibition on policy cancellation without consent
• Health insurance maintenance obligations
• Waiver of claims to cash value in whole life policies

Intellectual Property and Digital Assets

Modern Florida prenups should address intellectual property, cryptocurrencies, and digital assets. Under Florida law, intellectual property developed during marriage using marital efforts or resources may become partially marital property. If a spouse contributes to building a business brand, editing content, or investing marital funds into equipment, courts may find their involvement creates a marital interest in otherwise separate intellectual property.

Digital and IP provisions should address:

• Patents, copyrights, and trademarks owned before marriage
• Intellectual property created during marriage
• Social media accounts and influencer brand value
• Cryptocurrency holdings and future acquisitions
• NFTs and other digital collectibles
• Online business revenue streams
• Royalty and licensing income treatment

Estate Planning Integration

Florida prenuptial agreements can waive or modify statutory inheritance rights, including the elective share that entitles a surviving spouse to 30% of the decedent's estate under Fla. Stat. § 732.2065. Under Fla. Stat. § 61.079(3), couples can contract for disposition of property upon death, making prenups essential for blended families and estate planning. Homestead waiver requires two witnesses under Florida law to be enforceable.

Estate provisions should include:

• Elective share waiver or modification
• Homestead rights waiver (requires two witnesses)
• Life estate and remainder interest designations
• Trust beneficiary provisions
• Protection of inheritances for children from prior marriages
• Funeral and burial expense responsibilities

What Cannot Be Included in a Florida Prenup

Florida law prohibits certain provisions in prenuptial agreements, and including unenforceable terms may jeopardize the entire agreement. Under Fla. Stat. § 61.079(4), a prenup cannot adversely affect a child's right to support. Courts retain exclusive authority to determine child custody based on best interests at the time of separation.

Prohibited Provisions

Florida Prenup Execution Requirements

For a Florida prenuptial agreement to be enforceable under Fla. Stat. § 61.079, specific execution requirements must be met. The agreement must be in writing and signed by both parties. While notarization is not technically required, Florida attorneys strongly recommend having the document notarized with two adult witnesses to prevent future challenges to authenticity.

Financial Disclosure Requirements

Florida law requires fair and reasonable financial disclosure before signing unless the right is explicitly waived in writing. Under Fla. Stat. § 61.079(7), a prenup is unenforceable if the challenging party proves they were not provided fair disclosure, did not waive disclosure in writing, and did not have adequate knowledge of the other party's finances. Full disclosure includes all assets, debts, income sources, and financial obligations.

Financial disclosure should include:

• Bank and investment account balances
• Real estate holdings with current valuations
• Business ownership interests and estimated values
• Retirement account balances
• Outstanding debts and liabilities
• Income from all sources
• Expected inheritances (optional but recommended)
• Tax returns for previous 2-3 years

Timing Considerations

Florida courts scrutinize prenups signed close to the wedding date for signs of duress or coercion. Best practice requires presenting the agreement at least 30 days before the wedding to allow adequate review time. Agreements signed within days of the ceremony face heightened scrutiny, with courts examining whether the signing party had meaningful opportunity to consult counsel and negotiate terms.

Independent Legal Counsel

While not legally required for validity, both parties having separate attorneys significantly strengthens enforceability. Florida judges are more likely to uphold agreements when each partner had independent counsel review the terms. Even if one party pays for the other's attorney, having separate legal advisers demonstrates fairness and undermines future claims of inadequate understanding.

Grounds for Invalidating a Florida Prenup

Under Fla. Stat. § 61.079(7), Florida prenuptial agreements are presumed valid, placing the burden on the challenging spouse to prove invalidity. Courts may invalidate a prenup if execution was involuntary, if fraud, duress, coercion, or overreaching occurred, if the agreement was unconscionable (shockingly unfair) when signed combined with inadequate disclosure, or if terms violate public policy.

Common Challenge Scenarios

Florida courts have invalidated prenups in these circumstances:

• Signing under extreme time pressure (days before wedding)
• Hidden assets or materially false financial disclosure
• Significant power imbalance without independent counsel
• Terms leaving one spouse destitute while other remains wealthy
• Language barriers without adequate translation
• Mental incapacity or intoxication at signing
• Threats to cancel wedding without signature

Modifying or Revoking a Florida Prenup

After marriage, Florida couples can amend, revoke, or abandon their prenuptial agreement only through a written agreement signed by both parties under Fla. Stat. § 61.079(6). No additional consideration beyond the signatures is required for the modification to be enforceable. Couples may also convert their prenup to a postnuptial agreement with different terms, or create a new postnuptial agreement that supersedes the original prenup.

Sunset clauses represent another modification approach. Some couples include provisions stating the prenup expires after a certain number of years (commonly 10-15 years) or upon a specific event like the birth of a child. Once the sunset clause triggers, the agreement terminates and default Florida law applies.

Florida Alimony Reform Impact on Prenups (SB 1416)

Governor DeSantis signed SB 1416 into law effective July 1, 2023, eliminating permanent alimony and restructuring durational alimony in Florida. While this reform significantly impacts divorce outcomes, a valid prenuptial agreement supersedes statutory alimony guidelines. Couples with existing alimony provisions in their prenup maintain those contractual terms regardless of the new law.

Key 2023 alimony changes:

Durational alimony under SB 1416 cannot exceed 35% of the difference between the parties' net incomes, and terminates upon remarriage or death. A prenup can establish different terms, including guaranteed minimum payments or complete waivers.

Special Considerations for Florida Prenups

Commingling Prevention

Separate property can lose its protected status if commingled with marital assets during the marriage. A Florida prenup should include specific anti-commingling provisions and procedures for maintaining separate property status. Best practices include maintaining separate bank accounts for premarital assets, documenting the source of funds for major purchases, keeping detailed records of separate property transactions, and using a dedicated business account for entrepreneurial income.

Appreciation of Separate Property

Under Fla. Stat. § 61.075, appreciation of nonmarital assets resulting from marital efforts becomes marital property subject to division. Active appreciation (from spouse's work) differs from passive appreciation (market forces). A prenup can specify that all appreciation remains separate property regardless of cause, or establish formulas for dividing only active appreciation.

Military Families

Military families face unique considerations in Florida prenups. While military retirement benefits can be addressed, the Uniformed Services Former Spouses Protection Act (USFSPA) governs federal treatment. A prenup can waive claims to military retirement, but the service member must ensure compliance with both Florida law and federal requirements. Military personnel stationed in Florida satisfy the 6-month residency requirement under Fla. Stat. § 61.021 even if their home of record is another state.

Frequently Asked Questions

Does Florida require notarization for a prenup to be valid?

Florida does not legally require notarization for prenuptial agreement validity under Fla. Stat. § 61.079, but attorneys strongly recommend it. A notarized prenup with two adult witnesses prevents future challenges to signature authenticity and demonstrates voluntary execution. The cost for notarization is typically $10-$25 per signature, a minimal investment protecting an agreement worth potentially millions.

Can I waive alimony completely in a Florida prenup?

Yes, Florida law explicitly permits complete alimony waivers in prenuptial agreements under Fla. Stat. § 61.079(3)(c). Courts honor these waivers unless the waiving spouse would become dependent on state assistance, or if duress or fraud occurred during signing. However, temporary alimony during divorce proceedings cannot be waived, as courts retain discretion over support during dissolution.

What happens if my Florida prenup is ruled invalid?

If a Florida court invalidates a prenuptial agreement, default state law applies to property division and alimony. Under Fla. Stat. § 61.075, marital property is subject to equitable distribution starting from a presumption of equal division. Alimony follows SB 1416 guidelines, with durational alimony capped at 35% of the income difference. Assets classified as separate in the invalid prenup become subject to court classification.

How much does a Florida prenuptial agreement cost?

Florida prenuptial agreement costs typically range from $1,500 to $10,000 depending on complexity, with average costs between $2,500 and $5,000 for standard agreements. Simple prenups protecting modest assets cost less, while agreements involving business valuations, multiple properties, or complex estate planning require more attorney time. Each party should have independent counsel, potentially doubling legal costs.

Can I include infidelity clauses in my Florida prenup?

Florida courts generally do not enforce infidelity or lifestyle clauses in prenuptial agreements because they address personal conduct rather than financial matters. While couples sometimes include these provisions, courts treat them as unenforceable. Focus prenup terms on property division, alimony, and other financial matters that courts consistently uphold under Fla. Stat. § 61.079.

How soon before my wedding should I sign the prenup?

Florida attorneys recommend presenting a prenuptial agreement at least 30 days before the wedding, with 60-90 days being optimal. Agreements signed within days of the ceremony face scrutiny for duress or coercion. Courts examine whether the signing party had meaningful time to review terms, consult independent counsel, and negotiate changes. Last-minute signatures suggest pressure rather than voluntary execution.

Does my prenup survive if we move to another state?

Florida prenuptial agreements generally remain enforceable if you relocate, but each state applies its own law to determine validity and interpretation. Florida's UPAA adoption provides consistency with the 28 other UPAA states. Include a choice-of-law provision specifying Florida law governs interpretation, which most states will honor. If moving is likely, consult with an attorney in your new state to verify enforceability.

Can a prenup protect my business from my spouse?

Yes, a Florida prenup can fully protect business interests from division upon divorce. Under the 2024 amendments to Fla. Stat. § 61.075, closely held business interests and enterprise goodwill are specifically defined as marital assets subject to distribution. A prenup can classify the business as separate property, exclude goodwill from division, prevent spouse from acquiring ownership interest, and protect business partners from divorce claims.
