As decades pass, financial circumstances evolve and a premarital contract drafted years earlier may no longer reflect a couple’s current reality. Under Virginia law, prenuptial agreements are not permanent, unchangeable documents. Spouses have specific legal mechanisms to modify, amend, or terminate an existing premarital agreement after marriage, provided the statutory requirements are met.
Statutory framework for Virginia premarital agreements
Premarital contracts in Virginia are governed by the Virginia Uniform Premarital Agreement Act. A prenuptial agreement becomes effective upon marriage and remains legally binding indefinitely unless one of three things happens: the agreement includes a sunset clause that causes it to expire, the spouses execute a written amendment or revocation after marriage, or a court determines the agreement is unenforceable during divorce proceedings.
Expiration through sunset clauses
Some prenuptial agreements include a built-in expiration mechanism. A sunset clause provides that the agreement, or specific provisions within it, will terminate automatically after a designated event occurs. Common examples include a time-based expiration on a specific anniversary, provisions that phase out upon the birth or adoption of a child, and financial thresholds that adjust or terminate certain terms once the marital estate reaches a defined net worth. When the triggering event occurs, the contract expires without requiring further court action, and standard Virginia equitable distribution and spousal support statutes apply in any subsequent divorce.
Amending or revoking a prenuptial agreement after marriage
If there is no sunset clause, spouses who wish to change or cancel their agreement must do so voluntarily through a formal post-marriage amendment or revocation. An amendment or revocation must be in writing and signed by both parties. Several requirements apply. The change cannot be made through oral promises or informal messages. Both spouses must sign voluntarily, free from duress or coercion. Importantly, Virginia law does not require new financial consideration to validate a post-marital amendment, meaning one spouse does not need to pay the other or trade an asset to make the change enforceable.
Grounds for challenging enforceability in court
When spouses disagree on whether an agreement should remain in effect, one party may challenge its validity during divorce proceedings. Under Va. Code section 20-150, a premarital agreement is unenforceable if the challenging spouse proves either that they did not sign voluntarily, or that the agreement was unconscionable when executed and the challenging spouse was not provided a fair and reasonable financial disclosure before signing and did not voluntarily waive their right to that disclosure in writing.
