Postnuptial Agreement: What Cannot Be Included in a Postnuptial Agreement

The postnuptial agreement is a contract between spouses that can address property division, debt allocation, and some financial matters during a marriage or in the event of divorce. However, certain provisions are not permissible or are heavily restricted under U.S. law. Understanding these limitations helps couples create a valid, enforceable agreement that stands up in court. This article outlines the key topics generally not allowed or enforceable in postnuptial agreements and explains why they are treated differently from other terms.

Provisions That Violates Public Policy Or The Law

Postnuptial agreements cannot include terms that require illegal acts or that promote illegal conduct. Any clause that compels fraud, wrongdoing, or noncompliance with the law is void and may render the entire agreement unenforceable. Courts will not honor provisions that conflict with criminal statutes or policy concerns. This includes any instruction to facilitate wrongdoing or evade legal obligations.

Child-Related Provisions And Decisions

In most states, provisions about custody, visitation, or child support are not fully binding. Postnuptial agreements cannot legitimately waive or cap a parent’s obligation to support a child or restrict a court’s ability to make custody determinations based on the child’s best interests. Courts may consider such terms but will not be bound by them if they conflict with a child’s welfare. Provisions attempting to prearrange or preclude future child support or custody arrangements are commonly deemed unenforceable or subject to independent review.

Specifically, while parents can outline preferences or expectations, the final decision on child-centered issues remains with the court, guided by current circumstances and accounting for best interests, safety, and well-being. Agreements that attempt to lock in specific custody or support terms often face strong scrutiny and may be disregarded.

Waivers Of Statutory Rights Without Adequate Consideration And Disclosure

Some states allow waivers of certain rights, such as spousal support or marital property rights, but only with appropriate disclosure and meaningful consideration. Provisions that attempt to waive or limit statutory rights without full financial disclosure, independent legal advice, and genuine mutual agreement may be invalid. Courts look for fair negotiation, informed consent, and lack of coercion when evaluating enforceability.

Future Rights To Social Security Or Pension Benefits

Postnuptial agreements cannot guarantee or predetermine future Social Security or pension benefits in a way that violates federal rules or creates inequitable results. While couples can negotiate the division of retirement accounts and benefits earned during the marriage, provisions that promise specific Social Security outcomes or that rely on speculative future changes may be challenged. Clarity and compliance with retirement-plan rules are essential.

Unconscionable Or Unreasonable Provisions

Provisions that are grossly unfair at the time of signing may be unenforceable. A court can refuse to enforce a postnuptial clause if it is one-sided, oppressive, or entered under duress. The reasonableness of terms, especially regarding property division and support, matters. Courts assess factors such as income disparity, assets, and the overall balance of the agreement.

Unclear Or Incomplete Agreements

Ambiguity can doom enforceability. Provisions must be clear, specific, and complete with respect to the assets, debts, and the intended treatment of property. Vague language about “all marital assets” or “fair division” without specifics is risky. Proper drafting reduces the chance that a clause will be misinterpreted or challenged later.

Non-Disclosure Or Silence About Violent Or Abusive Conduct

Courts may scrutinize provisions seeking to conceal misconduct, abuse, or coercive behavior. While parties can mutually agree on certain privacy aspects, agreements cannot be used to conceal illegal or harmful actions. Clauses attempting to silence a spouse about abuse or to circumvent protections may be deemed invalid and unenforceable.

Jurisdiction-Specific Limitations

Postnuptial enforcement varies by state. Some states impose stricter requirements on voluntary execution, independent legal counsel, or notarization, while others emphasize equitable outcomes. It is essential to tailor the document to the governing state’s laws and to include clauses that satisfy local standards for enforceability. Consulting a family-law attorney familiar with the relevant jurisdiction improves the odds of a durable agreement.

Best Practices To Avoid Invalid Provisions

• Full Financial Disclosure: Each party should disclose assets, debts, incomes, and other relevant financial information.
• Independent Legal Advice: Both spouses should have separate lawyers to review the agreement and ensure informed consent.
• Voluntary Signing: The agreement should be entered into without coercion, threats, or pressure.
• Written And Signed: Ensure the document is in writing, signed, and dated, with witnesses or a notary if required by state law.
• Clear Language: Use precise terms for property, spousal support, and debts to reduce ambiguity.
• Regular Updates: Revisit and revise the agreement after major life changes to keep terms current and enforceable.

What To Include Instead Of Prohibited Provisions

To create a robust postnuptial agreement, focus on permissible topics such as the division of marital property, debt allocation, handling of premarital assets, and the treatment of income earned during the marriage. Consider detailing how future inheritances, investment gains, or business interests will be managed. By anchoring the document in permissible, actionable terms, couples can achieve clarity and protection without running afoul of legal restrictions.
