Prenuptial Agreements in Virginia: The Rules, the Costs, and How to Get One

You are engaged, or close to it, and somewhere between picking a venue and finalizing the guest list, the word "prenup" came up. Maybe one of you owns a home. Maybe there is a business, or student debt, or a first marriage in the rearview mirror. You want to know what Virginia asks of you, what it costs, and whether the online route people keep mentioning is real.

The short version is reassuring. Virginia's Premarital Agreement Act, in effect since 1985, requires only that a prenup be in writing and signed by both partners, and it takes effect on marriage under Va. Code § 20-149. That is a light bar on paper. What follows is what "valid" and "enforceable" mean in practice, how Virginia divides property when there is no agreement, what the whole thing costs, and how couples across the state, from Fairfax to Hampton Roads, get a prenup in Virginia done.

Are prenups valid in Virginia?

Yes. Virginia recognizes premarital agreements under its Premarital Agreement Act, part of Title 20 of the Code of Virginia. The state adopted the framework in 1985, and it applies to any prenup signed in contemplation of marriage.

The formal requirements are short. Under Va. Code § 20-149, the agreement must be in writing and signed by both partners, and it becomes effective when you marry. Virginia does not require a notary. It does not require witnesses. It does not require consideration, meaning neither partner has to give up something of value in exchange for signing, the way you would in a typical contract. The signatures and the writing are what the statute asks for.

That does not mean formality is pointless. Notarizing your signatures is worth doing even though the law does not demand it, because a notarized signature is straightforward evidence that both partners signed of their own free will, which is the first thing a court looks at if the agreement is ever challenged. More on that next.

Virginia is one of the 29 states, plus the District of Columbia, that built its law on the Uniform Premarital Agreement Act, though Virginia made its own changes to the enforcement standard. You can see how it compares to other states in our state-by-state guide.

What makes a Virginia prenup enforceable?

Signing is one thing. Holding up years later, if a marriage ends and one partner wants out of the agreement, is another. This is where Virginia's law gets specific, and where couples should pay attention.

A Virginia court will not enforce a prenup on one of two grounds, laid out in Va. Code § 20-151. The first is involuntary signing: the challenging partner proves they did not sign the agreement voluntarily. The second is a combination. The agreement was unconscionable when it was signed, and the challenging partner was not given a fair and reasonable disclosure of the other partner's property and finances, and did not voluntarily and in writing waive the right to that disclosure.

Unconscionable is a legal way of saying so one-sided or unfair at the time of signing that a court treats the terms as beyond what the law will enforce. Under § 20-151, whether an agreement is unconscionable is decided by the court as a matter of law, not left to a jury.

Here is a detail that sets Virginia apart. The Uniform Premarital Agreement Act, which many states adopted, includes a third prong asking whether the challenging partner had, or reasonably could have had, adequate knowledge of the other's finances. Virginia dropped that third prong. The state's test rests on two pillars: voluntary signing, and, for the unconscionability path, fair disclosure or a written waiver of it. That makes disclosure and voluntariness the two things a Virginia couple should get right.

The practical takeaway is clear. Both partners should exchange a full picture of what they own and owe, and both should sign with enough time and understanding that no one could later claim they were pressured. For a deeper look at how these factors play out, see what makes a prenup enforceable.

How does Virginia divide property without a prenup?

If you skip a prenup and the marriage later ends, Virginia does not leave the outcome to chance. It applies equitable distribution under Va. Code § 20-107.3, the rule that a judge divides marital property based on what is fair in context, weighing a list of statutory factors, rather than splitting everything automatically down the middle.

This matters because "equitable" doesn't always mean "equal." Virginia is an equitable distribution state, not a community property state, so there is no statutory presumption that marital property gets divided 50/50. A judge weighs factors such as each partner's monetary and non-monetary contributions to the marriage and to the property, the length of the marriage, the circumstances that led to its end, and the debts and liabilities of each spouse. The result is whatever the court decides is fair given those facts.

For couples, that is the core reason a prenup exists. Without one, a judge you have never met applies a multi-factor statute to your assets. With one, you and your partner decide in advance what counts as separate and what counts as shared. You can read more about the default rules in what happens if you don't have a prenup.

What can a Virginia prenup cover?

Virginia gives couples wide latitude. Under Va. Code § 20-150, a prenup can address the rights and obligations each partner has in their property, the right to buy, sell, manage, or control property, and what happens to property on separation, divorce, or death. It can settle spousal support, the making of a will or trust, the disposition of a life insurance death benefit, and which state's law will govern the agreement.

In short, most of the financial and property questions a couple might want to answer in advance are on the table.

There is one boundary worth naming. A Virginia prenup cannot fix child support for a future child, and it cannot control custody. A Virginia court decides child support under the state's guidelines and keeps the final say, because those decisions turn on the child's best interests at the time, not on a document the parents signed years earlier. This limit is confirmed by the Virginia State Bar's guidance in its June 2023 Virginia Lawyer article on premarital agreements. You can put nearly everything else in writing; a child's support and custody stay with the court.

How much does a prenup cost in Virginia?

Cost is often the real question behind the research, and Virginia is not a cheap legal market. Because each partner should have their own view of the agreement, the traditional route means two attorneys, and the hourly math runs twice.

Northern Virginia family law attorneys commonly bill $275 to $500 an hour. When each partner retains their own lawyer, the couple's total commonly lands between $2,900 and $12,400, depending on how complex the assets are and how many rounds of edits the agreement goes through. For context, the Clio 2025 Legal Trends Report puts the average Virginia attorney rate, across all practice areas, at roughly $380 an hour. Family law work in the Northern Virginia corridor tends to sit at the higher end of that range.

There is another path. First offers a flat-fee online option built to Virginia's law, with online notarization included, so the cost is fixed for the couple rather than climbing with the clock.

How do you get a prenup in Virginia?

The mechanics are more approachable than most couples expect. Getting a prenup in Virginia comes down to a handful of steps, each tied to what the statute asks for.

Nothing in Virginia law requires either partner to hire an attorney, and nothing requires the agreement to be produced any particular way. That is what makes a flat-fee online prenup a legal, enforceable path in Virginia, as long as both partners disclosed, both signed voluntarily, and the terms are not unconscionable.

Frequently asked questions

Are prenups enforceable in Virginia?

Yes. Virginia's Premarital Agreement Act requires a prenup to be in writing and signed by both partners, and it takes effect when you marry. A court will set one aside only if the challenging partner proves they did not sign voluntarily, or that it was unconscionable when signed and they got neither fair disclosure nor a written waiver of it.

Does a Virginia prenup have to be notarized?

No. Virginia's Premarital Agreement Act requires only that the agreement be in writing and signed by both partners; it does not require notarization or witnesses. Notarizing is still worth doing, because a notarized signature is straightforward evidence that both partners signed voluntarily, which is the first thing a Virginia court examines.

Do both people need a lawyer for a prenup in Virginia?

No. Nothing in Virginia's Premarital Agreement Act requires either partner to be represented by an attorney for a prenup to be valid. What the statute tests is whether each partner signed voluntarily and whether each was given a fair and reasonable disclosure of the other's finances.

How much does a prenup cost in Virginia?

Hiring attorneys commonly runs $2,900 to $12,400 for the couple, billed at Northern Virginia rates of $275 to $500 an hour, since each partner needs their own attorney. With First, a Virginia prenup is a flat fee for the couple, completed online, with online notarization included.

Can I do a Virginia prenup online?

Yes. Nothing in Virginia law treats an agreement differently because of how it was produced. What matters is that both partners disclosed their finances, both signed voluntarily, the terms are not unconscionable, and the agreement was drafted to Virginia law.

When should we sign a prenup in Virginia?

As early as you reasonably can. Virginia has no statutory waiting period, but timing is one of the clearest signals a court reads when someone argues they did not sign voluntarily. Signing months ahead, after both partners have read it and had a real chance to ask questions, removes that argument.
