Virginia Prenuptial Agreement: What It Covers and What Makes It Enforceable

A Virginia prenuptial agreement is a written contract signed by two people before they marry that sets their own rules for property, debts, and spousal support if the marriage later ends. The Premarital Agreement Act at Code of Virginia §§ 20-147 through 20-155 governs these contracts and gives couples broad authority to replace the state’s default divorce rules with terms of their own choosing.¹ The signatures have to happen before the wedding, but the agreement itself only takes legal effect once the marriage actually occurs.

What You Can Put in a Virginia Prenup

Code of Virginia § 20-150 lays out a broad menu of subjects the agreement can cover. The reach is wider than most people expect.

Property rights in any asset, whenever and wherever acquired. You can designate a family business, an investment portfolio, or a future inheritance as one spouse’s separate property regardless of how Virginia would otherwise classify it.²
Who has authority to buy, sell, lease, or mortgage specific assets during the marriage.²
How assets get divided on separation, divorce, or the death of a spouse.
Spousal support, including modification or complete waiver, subject to one override discussed below.²
Life insurance death benefits and the creation of wills or trusts to carry out the agreement’s terms.²
Responsibility for pre-existing debts like student loans or credit card balances, and the handling of debt taken on during the marriage.
Which state’s law governs the agreement if the couple relocates.²
Any other matter, including personal rights and obligations, as long as the terms don’t violate public policy or criminal law.²

One quirk of Virginia law worth knowing: the agreement is enforceable without consideration.¹ Ordinary contracts require each side to give up something of value, but a prenup holds simply because both parties signed it before the marriage.

The appreciation issue is a big reason business owners sign prenups. Under the default rules, growth in the value of separate property stays separate if it comes from market forces alone, but any portion attributable to a spouse’s personal effort during the marriage becomes marital property subject to division.³ A spouse who grows a company from $200,000 to $2 million during the marriage could watch a substantial share of that appreciation get reclassified. The prenup lets you lock the classification in writing instead of leaving it to a judge years later.

What a Prenup Cannot Do

A prenup cannot waive or limit a child’s right to financial support. Virginia courts keep full authority over child support based on statutory guidelines, and no private contract between parents can override that. Custody and visitation terms are also unenforceable, because courts decide those issues based on the child’s circumstances at the time of separation rather than what two people agreed to years earlier.⁴

Any provision that would require illegal conduct or impose a criminal penalty is void. The catch-all authority in § 20-150 explicitly excludes those terms.²

Lifestyle clauses that try to regulate personal behavior during the marriage, such as infidelity penalties, social media restrictions, or household duty rules, are generally unenforceable in Virginia. Couples sometimes include them as aspirational language, but counting on a court to honor them is a mistake.

What Makes the Agreement Hold Up

Virginia asks for very little in the way of formalities, but it gives the signer two separate paths to invalidate the agreement later. Both need to be closed off while the ink is still wet.

Writing and Signatures

The agreement must be in writing and signed by both parties.¹ That is the full statutory requirement. Notarization is not required, but having both signatures notarized is standard practice because it makes it much harder for either side to later claim they didn’t actually sign. Each party should keep a signed original.

Voluntary Execution

The agreement is unenforceable if the person challenging it can prove they did not sign voluntarily.⁵ This is a standalone ground, meaning the agreement can be thrown out on this basis alone even if everything else looks fine. Handing a fiancé a prenup the night before the wedding, or pairing it with threats about canceling the ceremony, is exactly the kind of pressure courts examine. The further ahead of the wedding the signing happens, the harder a coercion argument becomes.

Unconscionability Plus Inadequate Disclosure

The second path to invalidation requires the challenger to prove two things together: that the agreement was unconscionable at the time of signing, and that they were not given fair and reasonable disclosure of the other party’s finances.⁵ Both elements have to be present. A lopsided agreement will survive if both parties went in with full knowledge of each other’s finances, and incomplete disclosure won’t sink an agreement whose terms are reasonable on their face.

A party can voluntarily waive the right to disclosure in writing.⁵ If that waiver is in place, the other side can’t later complain about not knowing enough. Relying on a waiver is still risky, because it tends to invite closer scrutiny of whether the overall deal was unconscionable.

The Spousal Support Safety Net

Even a validly executed waiver of spousal support can be overridden in one specific situation. If enforcing the waiver would leave one spouse eligible for public assistance at the time of separation or divorce, the court can order the other spouse to provide enough support to keep the disadvantaged spouse off public assistance, regardless of what the prenup says.⁵

Timing and Separate Lawyers

Virginia’s statute does not require each party to hire a separate attorney, but independent counsel on both sides is one of the strongest shields against a future challenge. A single lawyer representing both parties has a conflict of interest, and a one-sided arrangement leaves the unrepresented party with a ready-made argument that the signing wasn’t truly informed or voluntary.

Timing carries almost as much weight as the terms themselves. There is no statutory deadline for how far in advance the agreement must be signed, but last-minute presentation is one of the most common reasons these contracts get thrown out. Signing weeks or months before the wedding takes the “I felt trapped” argument off the table.

The Retirement Account Trap

This is where prenups most often fall short of what the parties thought they accomplished. Virginia law lets you include retirement account provisions in a prenup, but federal law has its own rules that override the contract on this point.

Employer-sponsored plans like 401(k)s and pensions are governed by the Employee Retirement Income Security Act. Under ERISA, a surviving spouse has automatic rights to plan benefits, and those rights can only be waived by a “spouse.” At the time a prenup is signed, the parties aren’t married yet, so a prenuptial waiver of retirement benefits is not a valid spousal waiver under federal law.⁶

To make the waiver stick, the parties need a second step after the wedding. The spouse giving up benefits must sign a written consent that identifies an alternate beneficiary or payment form, witnessed by a plan representative or a notary.⁶ The practical approach is to put a retirement waiver in the prenup and then confirm it through a postnuptial agreement or plan-specific waiver form once the marriage happens. Skip that second step and the prenup clause is essentially decorative.

If the marriage ends and retirement assets have to be divided, the plan won’t accept the prenup as a distribution order. A court must issue a Qualified Domestic Relations Order that meets the plan’s requirements and the standards in 29 U.S.C. § 1056. The prenup can establish the formula for how much each spouse receives, but the actual transfer takes a separate court order.

Changing or Canceling the Agreement After the Wedding

A prenuptial agreement is not permanent. Under Code of Virginia § 20-153, the parties can amend or completely revoke the agreement at any time after the marriage, but only through a new written agreement signed by both spouses.⁷ As with the original, no consideration is needed to make the change binding.

Verbal modifications don’t count. If one spouse casually agrees during the marriage to change a term, that conversation carries no legal weight unless it’s reduced to a signed writing. Virginia also allows married couples to enter entirely new marital agreements under § 20-155, following the same rules that apply to premarital agreements. The main difference is that a marital agreement takes effect immediately upon signing rather than waiting for a future event.⁸

Putting Together the Financial Disclosure

Because inadequate disclosure is one of the two paths to invalidation, the financial documentation is not optional. Each party should compile a complete picture of their finances and attach it to the agreement as a formal exhibit.

Real estate: current market values and outstanding mortgage balances for every property owned.
Financial accounts: recent statements for bank accounts, brokerage accounts, 401(k) plans, and IRAs.
Business interests: profit and loss statements and a current valuation for any business either party owns.
Income documentation: at least two years of tax returns and recent pay stubs.
Debts: student loans, credit card balances, car loans, and any other outstanding obligations.

This information gets organized into disclosure schedules that become part of the final contract. Gathering everything typically takes two to four weeks. A spouse who later discovers hidden assets or understated debts has a strong argument for throwing out the entire agreement, so complete and honest disclosure at the outset is the single most effective thing you can do to make the prenup hold up.
