Prenuptial agreements have a reputation as documents that protect the wealthier spouse at the other’s expense. A well-made agreement can do the opposite. It can protect the partner who plans to step back from work to raise children, the one bringing student debt into the marriage, and the one with children from a prior relationship, as well as the one who owns a business.
Whether an agreement actually protects both people depends on how it’s made: full financial disclosure, enough time, separate legal advice and terms each person understands. In Virginia, those safeguards also determine whether a court will enforce it.
What Virginia Law Requires
Virginia follows the Premarital Agreement Act, Va. Code §§ 20-147 through 20-155. The key rules:
| Requirement | What it means |
| In writing and signed by both (§ 20-149) | Oral promises don’t count. The agreement becomes effective when the couple marries |
| Broad permitted content (§ 20-150) | Property rights, division on divorce or death, spousal support, life insurance, choice of law and other lawful matters |
| Voluntary signing (§ 20-151) | An agreement signed under pressure or coercion can be unenforceable |
| Disclosure or written waiver (§ 20-151) | An unconscionable agreement can be set aside if the challenger didn’t receive fair disclosure and didn’t waive it in writing |
| Changes after marriage (§ 20-153) | Only by a written agreement signed by both spouses |
Under § 20-151, a court, not a jury, decides whether an agreement is unconscionable. Child support is treated differently from property and spousal support: courts keep the authority to set support in the child’s best interests, so provisions limiting child support generally won’t control.
Common Myths
“Prenups are only for the wealthy”
Many couples who benefit from an agreement aren’t wealthy. One partner may own a small business, expect an inheritance, carry significant student loans, or want to preserve assets for children from a prior relationship.
“Asking for one means you don’t trust each other”
The conversation often does the opposite. Working through income, debt, saving and spending before marriage reveals expectations that otherwise surface for the first time in a crisis. The agreement records those decisions so there’s less room for conflicting memories later.
“Once it’s signed, every term is guaranteed”
Not necessarily. Terms signed under pressure, without disclosure, or that leave one spouse in an unconscionable position can be challenged. A careful process is what makes the agreement durable.
How an Agreement Can Protect Both People
Complete disclosure
Each partner should share accurate information about income, real estate, investments, retirement accounts, business interests and debts. Attaching schedules of assets and debts to the agreement creates a record of what each person knew. Hiding an asset can undermine the agreement and the relationship.
Separate lawyers
Virginia doesn’t require each party to have a lawyer, but separate counsel is the strongest protection for both. Each lawyer can explain how the language affects their client’s rights and help negotiate changes. This guide to choosing a prenuptial agreement lawyer covers what to look for.
Specific terms rather than vague promises
Clear provisions about premarital debts, a future mortgage, retirement contributions and support are easier to apply years later than general statements of intent.
When Earnings Are Unequal
A large income gap doesn’t make an agreement unfair, but the terms should account for what happens if one partner reduces paid work to raise children, support the other’s career, or manage the household. That decision can cost years of earnings, retirement savings and career progress.
Consider a couple where one partner earns $150,000 and the other earns $55,000 and plans to leave work for several years after having children. A balanced agreement might address spousal support if the marriage ends, contributions to the lower earner’s retirement during those years, or ownership of savings built up in that period. Waiving all support in that situation, with no adjustment for time out of the workforce, is the kind of term most likely to be challenged later.
Separate vs. Marital Property in Virginia
Without an agreement, Virginia divides property under its equitable distribution statute, Va. Code § 20-107.3, which classifies property as separate, marital or part of each. Property owned before marriage, gifts and inheritances generally start as separate, while property acquired during the marriage is generally marital. Equitable distribution doesn’t mean an automatic 50/50 split, and the lines blur easily. Separate funds deposited into a joint account, or marital money used to pay down a premarital mortgage, can create mixed property that is hard to untangle.
A prenuptial agreement can set these rules in advance: whether a premarital home’s increase in value stays separate, how contributions to it are credited, and whether an inheritance remains separate even if used for shared expenses. Keeping account statements, deeds and business valuations from the date of marriage makes those terms easier to apply.
Protecting a Business
For business owners, an agreement can address whether the business and its growth remain separate, how a spouse’s work in the business is recognized, and how the business would be valued. This piece on how a prenuptial agreement can protect a business goes into more detail.
Start the Conversation Early
Raise the subject months before the wedding, not weeks. That leaves time to exchange records, ask questions, get independent advice and negotiate changes. An agreement presented days before the ceremony invites claims that it wasn’t signed voluntarily.
- Agree on the reasons for the agreement: separating premarital debts, protecting a business, providing for children, or planning for a career break.
- Exchange financial information with supporting documents.
- Get separate legal advice and review every provision without rushing.
- Sign well before the wedding.
- Revisit the agreement after major changes such as children, a move or a new business. Virginia also allows spouses to make a marital agreement after the wedding under § 20-155.

Frequently Asked Questions
Is a prenuptial agreement enforceable in Virginia?
Yes, if it is in writing, signed by both parties and signed voluntarily. A court can refuse to enforce an unconscionable agreement if the challenging party didn’t receive fair disclosure and didn’t waive it in writing.
Can a Virginia prenup waive spousal support?
Spousal support is a permitted subject under Va. Code § 20-150, but a waiver that leaves one spouse in an unconscionable position is the type of term most often challenged.
Can we sign a prenup after we’re married in Virginia?
Yes. Virginia allows marital agreements after the wedding under § 20-155, and they take effect when signed.
