A prenuptial agreement in Virginia must be in writing and signed by both parties, is enforceable without consideration, and takes effect upon marriage. Virginia Code § 20-149 sets those formalities, and § 20-151 sets the two grounds on which a court will refuse to enforce one: that a party did not execute it voluntarily, or that the agreement was unconscionable when signed and that party was neither given fair and reasonable disclosure of the other's property and financial obligations nor expressly waived that disclosure in writing.
That second ground is narrower than most people assume, and the distinction matters: an agreement being one-sided is not by itself enough to void it. Unconscionability has to be paired with a disclosure failure. Which is precisely why full financial disclosure, documented at the time, is the single most important thing you can do to make a Virginia prenup survive a later challenge.
A well-drafted premarital agreement protects what matters most to each spouse going into a marriage — business interests, separate property, family wealth, professional practices, and estate-planning intentions. It removes uncertainty from the most stressful financial questions a relationship can face and, in the unlikely event of divorce, replaces years of contested litigation with a contract the parties chose together.
Randall J. Borden has drafted and reviewed premarital and postnuptial agreements for Northern Virginia clients for more than thirty years. The practice serves clients in Fairfax, Loudoun, Prince William, Arlington, and Alexandria — from straightforward agreements between couples with modest separate property to sophisticated documents protecting professional practices and multi-generational wealth.
What a Premarital Agreement Can Do in Virginia
Under the Virginia Premarital Agreement Act (Va. Code §§ 20-147 et seq.), a premarital agreement can address:
- The rights and obligations of each party in property of either or both spouses;
- The right to buy, sell, lease, transfer, exchange, mortgage, or otherwise manage and control property;
- The disposition of property upon separation, marital dissolution, death, or other event;
- The modification or elimination of spousal support (within limits);
- The making of a will, trust, or other arrangement to carry out the agreement;
- The ownership rights in and disposition of the death benefit from a life-insurance policy;
- The choice of law governing the agreement;
- Any other matter not in violation of public policy or criminal law.
What a Premarital Agreement Cannot Do
Virginia law does not permit a premarital agreement to adversely affect the right of a child to support. Custody and child-support provisions are decided by the court based on the child’s best interests at the time of dissolution, not by an agreement signed years earlier.
When a Prenuptial Agreement Makes Sense
- One or both parties bring significant separate property into the marriage;
- One party owns a business or professional practice;
- There are children from a prior marriage to protect;
- One party expects significant inheritance;
- One party has significant debt the other wants to protect against;
- The parties want certainty around separate vs. marital property going forward;
- A second marriage where each party wants estate-planning certainty;
- Significant income or earning-capacity asymmetry.
Requirements for an Enforceable Virginia Prenup
For a premarital agreement to be enforceable in Virginia, it must be:
- In writing and signed by both parties;
- Entered into voluntarily — without coercion or duress;
- Not unconscionable when signed;
- Preceded by fair and reasonable disclosure of property and financial obligations, or signed with knowing waiver of that disclosure.
An agreement signed under time pressure — for instance, the day before the wedding — is at risk of being challenged on duress grounds. Best practice is to begin discussions and document drafting months before the wedding.
Independent Counsel for Each Spouse
An enforceable premarital agreement requires both parties to enter the contract with full understanding of what they are giving up. The best way to demonstrate that — and to insulate the agreement from later challenge — is for each spouse to have independent counsel review and advise on the document. We routinely draft on behalf of one spouse and refer the other to independent counsel.
Postnuptial Agreements
A postnuptial agreement is an agreement entered into during the marriage rather than before. Common reasons include:
- Reconciliation after a period of separation;
- One spouse’s receipt of a substantial inheritance;
- Changes in business ownership or career;
- Estate-planning clarity;
- Establishing separate-property treatment of assets acquired during the marriage.
Postnuptial agreements are scrutinized more strictly than premarital agreements because the parties are already married and the consideration analysis is different. Drafting carefully matters.
Drafting That Will Hold Up
A premarital agreement is only as valuable as its enforceability. Common drafting mistakes that result in unenforceable agreements:
- Inadequate financial disclosure exhibits;
- Last-minute presentation (duress);
- One spouse without independent counsel;
- Provisions that are unconscionable on their face;
- Attempts to bind child-support or custody;
- Vague or contradictory provisions;
- Failure to address what happens upon death versus dissolution;
- No sunset or review provision in marriages of very long duration.
Schedule a Premarital Agreement Consultation
The best time to draft a premarital agreement is months before the wedding — not weeks. Call 703-385-8722 or request a private consultation. All consultations are confidential.
What Virginia law lets you put in a prenuptial agreement
Under Virginia Code § 20-150, parties to a premarital agreement may contract about:
- The rights and obligations of each party in any of their property
- The right to manage and control property
- The disposition of property on separation, dissolution of the marriage, death, or any other event
- Spousal support — including modifying or eliminating it
- Making a will or trust to carry out the agreement
- The ownership rights in and disposition of a life insurance death benefit
- The choice of law governing interpretation of the agreement
- Any other matter, including personal rights and obligations, not in violation of public policy or a statute imposing a criminal penalty
Child support is not among them. Section 20-150 enumerates what parties may settle and support for a child is not on that list. Separately, a Virginia court asked to decide child support applies the statutory guideline in its own right. So a prenup can settle what the two of you owe each other; it cannot settle what you owe a child.
Why Virginia prenups fail
In practice, challenges cluster around a handful of avoidable failures.
Inadequate disclosure. Section 20-151 pairs unconscionability with a disclosure failure, so incomplete disclosure is what converts a harsh agreement into an unenforceable one. Attach schedules of assets, debts and income, and keep the drafts that show what was exchanged and when.
Signing under pressure. An agreement produced days before a wedding invites the argument that it was not executed voluntarily. Time is your friend here; a prenup negotiated months ahead is considerably more durable than one signed at the rehearsal dinner.
No independent review. Virginia does not require each party to have their own attorney, but an agreement where one side had counsel and the other had none is a far easier target. Independent review is cheap insurance.
Vague drafting. Terms that do not define what happens to a business founded during the marriage, to appreciation on separate property, or to a jointly bought home tend to produce exactly the litigation the agreement was meant to prevent.
Who actually benefits from one
Prenups are not only for the wealthy. They do the most work where there is something specific to protect or clarify: a business or professional practice, an interest in a family enterprise, an expected inheritance, substantial premarital retirement savings, significant student or business debt one party does not wish to share, children from a prior relationship whose inheritance you want to secure, or a second marriage later in life where both parties arrive with established estates. They are also useful where one spouse will step back from a career — agreeing in advance how that is recognized avoids arguing about it a decade later.
Prenuptial agreement questions
Does a Virginia prenup have to be notarized?
Section 20-149 requires that the agreement be in writing and signed by both parties. Proper execution and acknowledgment is nevertheless the safer course, and it matters to how easily the agreement is later proved and incorporated, so this is not a corner worth cutting.
Do we each need our own lawyer?
Virginia does not require it. But an agreement where only one party had counsel is markedly easier to attack on voluntariness, so independent review is strongly advisable for the party who did not draft it.
Can a prenup waive spousal support?
Yes. Section 20-150 expressly permits parties to modify or eliminate spousal support. Whether such a term survives challenge still depends on voluntariness and disclosure.
Can we decide custody in advance?
No, not bindingly. Virginia courts decide custody on the child's best interests at the time of the dispute, and parents cannot contract that authority away.
How late can we sign one?
It must be before the marriage — it becomes effective upon marriage. Signing shortly before the wedding is legally possible but strategically poor, because proximity to the ceremony is the classic basis for a voluntariness challenge.
Can a prenup be changed later?
Yes, by a written agreement signed by both parties. Couples already married who want similar terms need a postnuptial agreement rather than a prenup.
Will a court enforce it if it seems unfair?
Unfairness alone is not the test. Under § 20-151 the agreement must have been unconscionable when executed and accompanied by a failure of disclosure without a written waiver, or else not voluntarily executed.
