A prenuptial agreement is enforceable in Virginia, and it is far more ordinary than most couples expect. Under the Virginia Premarital Agreement Act, two people who are planning to marry can decide in advance how their property, debts, and spousal support will be handled if the marriage ever ends. The agreement takes effect the moment you marry. What trips couples up is not whether prenups are allowed in the Commonwealth. It is understanding what a prenup can actually control, and what makes one hold up years later when it matters.
I am Miles Franklin, and I help couples across Stafford, Fredericksburg, and Spotsylvania put these agreements together the right way. This guide walks through what Virginia law permits, what it does not, and the two specific reasons a judge can set a prenup aside.
TL;DR
- Prenups are valid in Virginia under the Premarital Agreement Act (Va. Code § 20-147 and following). They must be in writing and signed by both people, and they take effect upon marriage.
- A prenup can settle property rights, debt, spousal support, and estate matters. It cannot decide child custody, visitation, or child support.
- A Virginia judge can set a prenup aside for only two reasons: you did not sign it voluntarily, or it was unconscionable and you never received or waived a fair financial disclosure.
- A one-sided agreement is not automatically invalid. Fairness alone is not the test.
- Couples who marry can sign a postnuptial agreement instead, which works the same way but takes effect immediately.
Are prenuptial agreements enforceable in Virginia?
Yes. Virginia has recognized prenuptial agreements since 1985, when the General Assembly adopted the Premarital Agreement Act. The Act governs every premarital agreement signed in the Commonwealth on or after July 1, 1986. Under Virginia Code § 20-149, the agreement must be in writing and signed by both parties, it is enforceable without consideration, and it becomes effective upon marriage.
That last point matters. A prenup is a contract you sign before the wedding, but it does nothing until you actually marry. If the wedding never happens, the agreement never takes effect. Once you are married, the terms you agreed to are binding, and a court will enforce them unless the person challenging the agreement can prove one of the narrow exceptions discussed below.
What is a prenuptial agreement under Virginia law?
A prenuptial agreement, which Virginia law calls a premarital agreement, is a contract between two people made in contemplation of marriage and effective upon marriage. In plain terms, it is a written plan for how you and your future spouse will handle money and property, both during the marriage and if it ends through divorce or death.
People sometimes assume a prenup is only about divorce. It is not. A well-drafted agreement also coordinates with your estate plan, protects a family business, and spells out who is responsible for debts each person brings into the marriage. It removes uncertainty, which is the opposite of what most people fear when they hear the word “prenup.”
What a Virginia prenup can and cannot control
Virginia Code § 20-150 lists what couples may put in a premarital agreement. The list is broad when it comes to property and finances, and it has firm limits when it comes to children. The table below shows the line Virginia draws.
| A Virginia prenup CAN address | A Virginia prenup CANNOT decide |
|---|---|
| What property stays separate and what becomes marital | Child custody or visitation |
| How property and debt are divided at separation, divorce, or death | Child support |
| Spousal support: defining it, capping it, or waiving it | Anything illegal or against public policy |
| Wills, trusts, and life-insurance death benefits | Day-to-day lifestyle terms a court will not enforce |
| Which state’s law governs the agreement |
The limits on the right side are not arbitrary. Anything touching your children is off the table because those rights belong to the child, not to the parents. A Virginia court always decides custody and visitation according to the best interests of the child, and it always retains authority to set or revise child support under the state guidelines. You cannot bargain those decisions away before a child is even born, and a clause that tries to will simply be ignored.
You should also leave out the “lifestyle” provisions you may have seen online, such as rules about chores, weight, or social media. Virginia courts will not enforce them, and including them can make the rest of the agreement look less serious.
What makes a Virginia prenup get thrown out?
This is the question I get most often, and the answer surprises people: a prenup does not fail just because it is one-sided. Under Virginia Code § 20-151, the spouse challenging the agreement has to prove one of only two things.
First, that they did not sign it voluntarily. This is where a last-minute prenup gets dangerous. If one person is handed an agreement days before the wedding, with guests already arriving and no time to read it or talk to a lawyer, a judge may find the signature was the product of pressure rather than free choice.
Second, that the agreement was unconscionable when it was signed and the financial disclosure was inadequate. This is a combined test, and both parts have to be met. The challenger must show the agreement was unconscionable, and that before signing they were not given a fair and reasonable disclosure of the other person’s property and debts, did not waive that disclosure in writing, and could not reasonably have known about those finances on their own.
One detail matters to anyone worried about a fight later: in Virginia, whether an agreement is unconscionable is decided by the judge as a matter of law, not by a jury, and statements made in the agreement itself are presumed to be true. That is exactly why honest, complete financial disclosure at signing is the single best protection a prenup can have.
The requirements for a valid prenuptial agreement
Pulling the rules together, a prenuptial agreement in Virginia needs to meet a short list of formal requirements to be enforceable. None of them are complicated, but skipping any one of them creates a problem.
- In writing. Oral promises about property are not enforceable as a prenup. The agreement has to be a written document.
- Signed by both parties. Both future spouses must sign. Notarization is not strictly required by statute, but I recommend it, because it removes any later argument about whether a signature was genuine.
- No consideration needed. Unlike most contracts, a prenup does not require an exchange of money or property to be valid. Virginia law makes a premarital agreement enforceable without consideration.
- Signed voluntarily, with real disclosure. Each person should understand the other’s finances and have genuine time to review the agreement and consult their own attorney.
The thread running through all of this is time. The further ahead of the wedding you sign, the stronger the agreement. Giving each person their own lawyer and several weeks to review the terms is the most reliable way to keep a prenup from being challenged as involuntary later.
Can you write your own prenup in Virginia?
You can, but I would caution against it. Nothing in Virginia law requires an attorney to draft a premarital agreement, so a do-it-yourself or template prenup is technically possible. The trouble is that the parts most likely to be challenged later, voluntariness and financial disclosure, are also the parts a template cannot manage for you.
When each person has independent counsel, it becomes very hard for either spouse to later claim they did not understand the agreement or were pressured into it. That is not a sales pitch; it is the practical reason courts give more weight to agreements where both sides were represented. A prenup is one document where trying to save money up front often costs far more if the agreement is contested during a divorce.
Prenuptial vs. postnuptial agreements in Virginia
If you are already married, you have not missed your chance. Virginia Code § 20-155 lets married couples sign a postnuptial agreement that settles the same rights as a prenup, under the same standards. The main difference is timing: a postnuptial agreement takes effect immediately when you sign it, rather than waiting on a wedding.
| Prenuptial agreement | Postnuptial agreement | |
|---|---|---|
| When you sign it | Before the marriage | During the marriage |
| When it takes effect | Upon marriage | Immediately on signing |
| What it can cover | Property, debt, spousal support, estate terms | The same matters |
| Common use | Protect premarital assets, set expectations | Address changes after marriage or a new business |
One Virginia-specific point worth knowing: if you sign a separation or property settlement agreement and then reconcile, the agreement is automatically canceled unless it expressly says otherwise. That rule, also in § 20-155, catches couples off guard, so it is worth addressing directly in any agreement signed while a marriage is on uncertain ground.
Why couples actually get prenups
A prenup is not a prediction that a marriage will fail. In my experience, the couples who sign them are usually the ones taking marriage most seriously, because they are willing to have an honest conversation about money before the wedding rather than during a crisis. A premarital agreement is most useful when one or both people are bringing real assets, debts, or obligations into the marriage.
Common situations include a second marriage where one spouse wants to protect an inheritance for children from a first marriage, a business owner who does not want a future divorce to disrupt the company, a couple where one person carries significant premarital debt, or partners with very different income or asset levels who simply want clear expectations. In every one of these, the agreement protects both people, not just the wealthier one. If your plans involve an estate plan or future spousal support questions, a prenup lets you settle them on your own terms instead of leaving them to a court later.
Frequently Asked Questions
Are prenuptial agreements enforceable in Virginia?
Yes. Virginia enforces prenuptial agreements under the Premarital Agreement Act. The agreement must be in writing and signed by both parties, and it becomes effective upon marriage. A court will uphold it unless the challenging spouse proves it was signed involuntarily, or that it was unconscionable and made without fair financial disclosure.
What cannot be included in a prenup in Virginia?
A Virginia prenup cannot decide child custody, visitation, or child support, because those rights belong to the child and remain with the court under the best-interests standard. It also cannot require anything illegal or contrary to public policy, and courts will not enforce personal lifestyle clauses such as rules about chores or appearance.
How much does a prenuptial agreement cost in Virginia?
The cost depends on how complex your finances are. A straightforward agreement between two people with simple assets takes far less work than one involving a business, multiple properties, or blended-family estate planning. Whatever the figure, it is modest compared with the cost of litigating those same issues in a contested divorce. I am happy to give you a clear quote during a consultation.
Can I write my own prenup in Virginia?
You are allowed to, but it is risky. Virginia does not require an attorney to draft a premarital agreement, yet the issues that most often void a prenup, voluntariness and full financial disclosure, are exactly what a template cannot handle. Having each spouse work with their own attorney makes the agreement much harder to challenge later.
Can a prenup be changed after we are married?
Yes. You can amend a prenuptial agreement in writing if both spouses agree, or you can sign a postnuptial agreement under Virginia Code § 20-155, which settles the same matters and takes effect immediately. Any change should be made in writing and signed by both parties, just like the original.
Does signing a prenup mean we are planning to divorce?
No. A prenup is a planning tool, not a forecast. It works much like insurance or an estate plan: you prepare for a possibility you hope never arrives. Most couples find that the honest financial conversation involved in creating one actually strengthens the marriage going in.
