Postnuptial Agreement Lawyer
Delina Yasmeh drafts postnuptial agreements for California couples whose financial picture has changed since the wedding, calibrated to the heightened-duty standard the courts apply between spouses.
Get Started →What most married entrepreneurs don't realize about California law.
A postnuptial agreement is a property agreement entered into after marriage. California is a community property state, so income earned during the marriage, and assets purchased with that income, are presumed to belong equally to both spouses regardless of who earned the money or whose name is on the account. A postnup lets married couples modify those defaults by written contract.
Courts apply heightened scrutiny to postnups that prenups do not face. Because spouses already owe each other a fiduciary duty, any transaction between them is presumed to result from undue influence if it advantages one over the other. That heightened-duty framework is the reason Delina declines a meaningful share of the postnup engagements that come in. It is also the reason a properly drafted postnup carries weight where a poorly drafted one will not survive the first challenge.
For couples where one spouse's business has grown materially, where a sale or inheritance has shifted the asset profile, or who never executed a prenup and want a property framework now, the postnup is the way to opt out of the default characterization with terms the couple chooses. The standard for enforcement is high: full and accurate disclosure, genuinely independent counsel for the non-drafting spouse, voluntary execution, and adequate, documented consideration where one spouse waives a property right.
Unlike a prenup, a postnup is entered without the wedding-as-consideration framework that supports premarital agreements, so the record has to be cleaner. Delina builds that record into every engagement, and where the dynamics signal an agreement that will not hold, she declines and explains why.
What Delina's postnuptial agreements address.
Business Appreciation Going Forward
If one spouse's business has grown materially since the wedding, the appreciation attributable to community labor is reallocated under California's characterization framework. A postnup is the way to opt out of that default with explicit characterization going forward, provided the agreement clears the heightened-duty bar the courts apply between spouses.
Liquidity Events & Inheritance
A business sale, a major liquidity event, an inheritance, or a windfall changes the asset profile in ways the default characterization no longer fits. Delina drafts agreements that handle the shifted picture, with the tracing analysis California family law requires where prior commingling has to be unwound or accepted going forward.
The Heightened-Duty Standard
Spouses owe each other a fiduciary duty, so any transaction that advantages one over the other is presumed to result from undue influence. The spouse asserting the agreement carries the burden of rebutting that presumption with clear and convincing evidence of full disclosure, separate counsel, voluntariness, and adequate consideration. Delina builds that record into every engagement.
When the Firm Declines
Where one spouse is pushing the other toward an agreement that would not survive an undue-influence challenge, where the consideration on the disadvantaged side is illusory, or where the timing is driven by an event that signals coercion, Delina declines and explains why. Drafting an agreement that fails enforcement does not protect anyone.
Amending an Existing Prenup
An amendment to a prenuptial agreement during the marriage is itself a postnuptial agreement subject to the heightened-duty framework. Where the original prenup no longer fits the situation, Delina drafts the amendment with the cleaner record the post-wedding standard requires.
LLC Formation in Parallel
Where a spouse is starting or acquiring a business mid-marriage and wants the appreciation kept separate, the post-marital LLC formation and the postnup run together, with the operating agreement spousal consent and the postnup characterization aligned before either is executed.
What most people want to know.
How long after marriage can you get a postnuptial agreement in California?
There is no statutory deadline. Couples can execute a valid postnuptial agreement at any point during the marriage, as long as both spouses have independent legal counsel, make full and accurate financial disclosure, and sign voluntarily with adequate consideration on the disadvantaged side. Courts look more carefully at postnups executed during periods of marital distress, so the earlier and the calmer, the better the record.
Is a postnuptial agreement legally binding in California?
Yes, when properly executed, but the standard is higher than for a prenup. Because spouses already owe each other a fiduciary duty, any transaction between them that advantages one over the other is presumed to result from undue influence. The agreement is enforceable only where the drafting record rebuts that presumption with full disclosure, independent counsel, voluntariness, and adequate consideration. A poorly drafted postnup will not survive the first challenge.
Why does a postnuptial agreement need a cleaner record than a prenup?
Spouses owe each other a fiduciary duty that does not apply between fiances before marriage, so the courts apply heightened scrutiny to anything signed after the wedding. The disclosures must be more thorough, the consideration on the disadvantaged side must be substantive rather than nominal, the independent counsel must be genuinely independent, and the timing must allow meaningful review with no event in the relationship driving it. That is why the standard postnup engagement runs six to ten weeks.
Do you need a lawyer for a postnuptial agreement?
Yes. California courts scrutinize agreements between spouses closely because of the marital fiduciary relationship. An agreement drafted without genuinely independent counsel for both spouses is vulnerable to challenge on grounds of undue influence or inadequate disclosure. Delina strongly recommends actual representation rather than waiver for postnups, and represents one spouse in each engagement while coordinating with independent counsel for the other.
