A postnuptial agreement (sometimes called a “postnup”) is a written contract created by spouses after they are legally married or have entered a civil union. Like a prenup, it defines how assets, debts, spousal support, and even infidelity consequences will be handled in the event of separation, divorce, or death.
According to IRS Publication 504 (Divorced or Separated Individuals), marital agreements that meet state law requirements are generally recognized for federal tax purposes as well (IRS.gov).
Common reasons my clients request a post nuptial agreement form in 2025:
Every state except two now recognizes postnups to some degree. The American Bar Association and Uniform Law Commission’s Uniform Premarital and Marital Agreements Act (2012) has been adopted in whole or part by more than 30 states, making enforcement far more predictable.
| State | Postnups Generally Enforceable? | Key Requirement |
|---|---|---|
| Florida | Yes | Full financial disclosure + fair and reasonable (Fla. Stat. §61.079) |
| California | Yes | 7-day waiting period + independent counsel strongly recommended (Fam. Code §1615) |
| Texas | Yes | Voluntary + not unconscionable (Tex. Fam. Code §4.102) |
| New York | Yes | Must be in writing, notarized, and fair (DRL §236B) |

My completely free downloadable postnuptial agreement template Word and postnuptial agreement sample PDF contains:
ARTICLE 3 – SEPARATE PROPERTY
3.1 The parties agree that all property listed in Schedule A (Husband’s Separate Property) and Schedule B (Wife’s Separate Property) shall remain the sole and separate property of the owning spouse, including any appreciation, income, or proceeds derived therefrom, regardless of whether title is held jointly for convenience.
ARTICLE 7 – INFIDELITY CONSEQUENCE (OPTIONAL)
7.1 In the event either party engages in sexual infidelity during the marriage, the non-breaching party shall receive 70% of the marital estate in any subsequent divorce proceeding, provided the infidelity is proven by preponderance of evidence.
Florida courts are friendly to postnups but require:
In my practice, I see the same fatal errors:
If your combined net worth is under $1 million and you have no complex business interests or children from prior relationships, my free postnuptial agreement template—when properly completed, notarized, and accompanied by full disclosure—can be a cost-effective solution.
If your situation involves seven-figure assets, trusts, international property, or recent infidelity, spend the $2,500–$7,500 for custom drafting. It’s the best insurance policy you’ll ever buy.
