Florida Prenuptial & Postnuptial Agreement

A prenuptial agreement (prenup) is a written contract signed before marriage that outlines how assets, debts, and certain financial issues will be handled if the marriage ends in divorce or death.

A strong prenup can address:

Property Division

How premarital and marital assets will be classified and divided.

Debt Allocation

Responsibility for student loans, business liabilities, or other financial obligations.

Business Ownership

Protection for family businesses, professional practices, or investment interests.

Spousal Support (Alimony)

Agreements regarding modification, limitation, or waiver of alimony, subject to Florida law.

Thinking Attorney note: enforceability depends on proper disclosure and voluntary execution. Process matters as much as the document itself.

What Is a Postnuptial Agreement?

A postnuptial agreement (postnup) is similar to a prenup but signed after the marriage has already begun.

Couples often consider postnuptial agreements when:

• One spouse starts or acquires a business
• There is a significant inheritance
• Financial circumstances change
• The couple reconciles after marital strain
• Asset protection becomes a priority

Postnuptial agreements must meet legal standards for fairness and full disclosure to remain enforceable.

What Makes a Florida Prenup or Postnup Enforceable?

Florida courts evaluate marital agreements carefully. Common enforceability considerations include:

Full Financial Disclosure

Each party should provide fair and reasonable disclosure of assets and liabilities.

Voluntary Execution

The agreement must not be signed under coercion or duress.

Proper Timing

Last-minute agreements presented immediately before a wedding can create challenges later.

Clear and Unambiguous Terms

Vague provisions often lead to litigation instead of protection.

A properly structured agreement anticipates potential disputes and addresses them clearly.

What Cannot Be Included in a Florida Prenup?

Certain issues cannot be predetermined in a marital agreement, including:

• Child custody determinations
• Child support waivers

Florida courts retain authority over child-related issues based on the child’s best interests at the time of any dispute.

When Should You Consider a Marital Agreement?

Prenuptial and postnuptial agreements are especially worth considering when:

There Is Significant Premarital Property

Real estate, investments, retirement accounts, or inherited wealth.

One Party Owns a Business

Protecting business continuity can be critical.

There Are Children From a Prior Relationship

Clarity in estate and property planning reduces conflict later.

Income Levels Differ Significantly

A structured agreement can provide predictability for both spouses.
