Virginia Postnuptial Agreement: Requirements and Enforcement

A Virginia postnuptial agreement is a written contract signed by spouses who are already married that sets the rules for their property, debts, spousal support, and inheritance rights during the marriage or if it ends. Virginia enforces these agreements under the same statute that governs prenuptial agreements, and they take effect the moment both spouses sign.¹ Done correctly, the agreement replaces Virginia’s equitable distribution guesswork with terms the spouses chose themselves.²

The Statute Behind It

Virginia regulates postnuptial agreements through the Premarital Agreement Act, Code sections 20-147 through 20-155.³ Section 20-155 extends every rule from the premarital framework to agreements between people who are already married.¹

One question that trips up postnuptial agreements in other states does not apply here. Virginia’s statute says a marital agreement is enforceable without consideration.⁴ Neither spouse has to give up something new to make the contract binding. The mutual promises are enough.

What Makes a Postnuptial Agreement Enforceable

Three questions decide whether a Virginia court will enforce the agreement: Was it signed? Was the signing voluntary? And was it either fairly disclosed or at least not unconscionable?

Writing and Signatures

The agreement must be in writing and signed by both spouses.⁴ Virginia does not require notarization, but most couples notarize anyway. The notary’s seal confirms the identity of each signer and makes the document self-authenticating if it ends up in court. Without that, a spouse who later wants out can challenge whether the signatures are genuine, and the argument is much harder to beat back without a notary in the room.

Voluntariness

If a spouse proves they signed under coercion, threats, or without mental capacity, the court can void the agreement.⁵ Voluntariness tends to draw more scrutiny in the postnuptial setting than in the premarital one. Spouses already share a household, finances, and often children, and that creates pressure that a court can read as duress. The strongest protection against a later challenge is simple: each spouse hires their own attorney, reviews the document independently, and signs without a deadline hanging over the discussion.

Disclosure and Unconscionability

A challenger has to prove two things to knock out the agreement on these grounds: the terms were unconscionable when signed, and they did not receive fair and reasonable disclosure of the other spouse’s finances.⁵ Both have to be present. An unfair agreement backed by full disclosure can still stand, and spotty disclosure paired with reasonable terms can also survive.

Virginia does let a spouse voluntarily waive, in writing, the right to further financial disclosure.⁵ Relying on that waiver is risky. The safer approach is a full exchange of tax returns, bank and investment statements, business valuations, and debt schedules. Any factual statements written into the agreement itself carry a legal presumption of accuracy, which helps the disclosing spouse if the agreement is later attacked.

What You Can Put in the Agreement

Virginia gives spouses wide latitude. The statute authorizes agreements covering:

How each spouse’s property is classified, managed, and divided, whether acquired before or during the marriage
The right to buy, sell, mortgage, lease, or otherwise control specific assets
What happens to property on separation, divorce, or death
Whether spousal support will be paid, and if so, how much and for how long
Commitments to make or maintain wills and trusts that carry out the agreement
Ownership and beneficiary designations for life insurance policies
Which state’s law governs the agreement
Any other matter that does not violate public policy or a criminal statute⁶

Property Classification

Without an agreement, Virginia courts sort assets into separate property (owned before the marriage or received by gift or inheritance) and marital property (acquired during the marriage).² A postnuptial agreement lets spouses draw those lines themselves. A business launched during the marriage can be fixed as one spouse’s separate property. A pre-marriage house can be converted into shared marital property. Writing it down matters, because years of commingled funds often blur the line to the point where a court has to sort it out, and the sorting may surprise both of you.

Spousal Support

Spouses can waive support entirely, set a fixed amount and duration, or define the triggers that start and stop payments. One detail is easy to miss: for agreements signed on or after July 1, 2018, a court can still modify the support terms based on a material change in circumstances unless the agreement expressly states the amount or duration is non-modifiable.⁷ If you want the numbers locked in, the document has to say so.

Elective Share and Estate Rights

Virginia gives a surviving spouse a statutory right to claim a share of the deceased spouse’s augmented estate, regardless of what the will says.⁸ A postnuptial agreement can waive the elective share, the homestead allowance, exempt property, and the family allowance, in whole or in part. The waiver has to be in writing and signed by the spouse giving up the rights, and the same voluntariness and disclosure defenses apply.⁹ This is the clause that makes postnuptial agreements so useful in blended families, where each spouse wants children from a prior marriage to inherit specific assets.

Debt Allocation

You can spell out which spouse is responsible for a business loan, a student loan, or specific credit card balances. That allocation binds the two of you. It does not bind outside creditors. A bank that lent to one spouse can still pursue that spouse under the loan documents, no matter what the postnuptial agreement says. The practical value here is making sure the non-borrowing spouse does not absorb the obligation in a divorce property division.

Retirement Accounts

Retirement accounts need special handling because federal law overrides the state contract. Under ERISA, a spouse must personally consent in writing, witnessed by a notary or plan representative, to waive survivor benefits in most employer-sponsored plans.¹⁰ A general waiver tucked into a postnuptial agreement does not satisfy ERISA on its own. The waiving spouse has to sign the plan administrator’s own consent form. Skip that step and the plan pays out according to its rules, not your agreement.

What Virginia Courts Will Not Enforce

Some terms will not survive judicial review no matter how carefully drafted.

Child custody and visitation. Virginia judges decide custody based on the best interests of the child, and no agreement between parents can override that standard.¹¹ A postnuptial agreement that tries to fix the parenting schedule in advance will not bind the court.

Child support. Virginia calculates support under statutory guidelines, and the guideline amount carries a legal presumption of correctness. A court can only deviate after making written findings explaining why the guideline would be unjust.¹² A clause capping or waiving child support will not hold.

Divorce incentives. Provisions that reward a spouse financially for filing for divorce can be struck down as contrary to public policy, which the statute’s content section expressly protects.⁶ Infidelity clauses that impose financial penalties for cheating sit in a gray area. Virginia has moved toward no-fault divorce, and some courts are reluctant to attach monetary consequences to marital misconduct. These clauses are not automatically void, but do not count on enforcement.

Changing or Revoking the Agreement

Virginia lets spouses amend or revoke a postnuptial agreement at any time, but only through a new written agreement signed by both spouses.¹³ Oral agreements to change the terms have no legal effect, even when both spouses clearly intended the change. The amendment or revocation needs no additional consideration.

Treat the document as something that gets revisited. New business, inheritance, retirement, a big change in income: each of those is a reason to pull the agreement back out and update it. An outdated agreement can cause as many problems as none at all.

After You Sign

Both spouses should sign in front of a notary. Each should keep an original in a secure place like a fireproof safe or a bank safe-deposit box, and copies should go to each spouse’s attorney and financial planner so the estate plan, beneficiary designations, and retirement paperwork stay aligned. If the agreement covers real estate, consider recording it with the circuit court clerk in the county where the property sits; Virginia allows writings authorized by law to be recorded in the deed books, which puts future buyers and creditors on notice.¹⁴

The most common failure point comes after the ink dries. The agreement sets the plan, but each affected account has its own paperwork. Retirement beneficiary forms have to be updated. Life insurance policies may need new beneficiaries. ERISA waiver forms have to be filed directly with plan administrators. Finish those follow-ups and the agreement does what you drafted it to do.
