How to Discuss and Draft a Postnuptial Agreement With Your Spouse

Postnups: A Smart Move, Not a Sign of Trouble

Many couples assume that if they didn’t sign a prenup, it’s too late to create a marital agreement. Not true. A postnuptial agreement in Florida allows spouses to define financial expectations, responsibilities, and protections—after marriage.

And while the legal side matters, the conversation matters even more. Talking about a postnup with your spouse requires care, respect, and clarity.

What Is a Postnuptial Agreement?

A postnuptial agreement (or “postnup”) is a legally binding contract made between spouses after they’re already married. Like a prenup, it outlines how assets, debts, income, and property will be treated during the marriage and in the event of divorce or death.

  • Both spouses must enter into it voluntarily
  • There must be full and fair disclosure of financial information
  • The agreement cannot violate public policy or be grossly unfair

Why Consider a Postnuptial Agreement?

Couples pursue postnups for a variety of reasons:

  • One spouse starts or sells a business
  • There’s a change in income, assets, or inheritance
  • You’re blending families and want clarity for children
  • You want to clarify financial boundaries or responsibilities
  • To strengthen the marriage after past conflict or infidelity

Contrary to common belief, a postnup can be a tool for relationship trust—not division.

What to Include in a Florida Postnup

  • Division of property and debt
  • Spousal support (alimony) in case of divorce
  • Estate planning protections
  • Responsibility for business income or liabilities
  • Guidelines for savings, spending, and asset growth

Frequently Asked Questions

Is a postnup legally valid in Florida?

Yes—if it meets Florida’s requirements for fairness, disclosure, and voluntary agreement. It must be in writing and signed by both spouses.

Can a postnup include child custody or child support?

No. Child-related matters are determined by the court at the time of separation or divorce, based on the child’s best interest—not prior agreements.

What if my spouse thinks a postnup means I don’t trust them?

Approach it as a financial planning tool, not a relationship test. Focus on fairness, transparency, and protection for both parties.

How is a postnup different from a prenup?

They’re very similar in content, but a prenup is signed before marriage, and a postnup is signed after. The same legal standards generally apply.

Do we each need a lawyer to create a postnup?

It’s strongly recommended. Independent legal counsel helps ensure both parties fully understand the terms, which protects enforceability.
