Here's the short answer: marriage doesn't cancel a trust outright. But most states, including California, have "omitted spouse" laws designed to protect a new spouse if your trust wasn't updated to reflect the marriage. That means an outdated trust can still be legally valid and still get overridden in part, by statute.
This article breaks down how omitted spouse rules work, how community property changes the picture, the difference between revocable and irrevocable trusts, and what to actually do about it.
Key Takeaways
- Marriage doesn't cancel a trust, but omitted-spouse laws can still give a new spouse a share
- Community property states like California treat marital earnings differently from pre-marriage assets
- Revocable trusts can be amended anytime; irrevocable trusts generally cannot
- Update your trust soon after marriage to avoid a later probate fight
What Happens to a Living Trust When You Get Married?
California law assumes that if you got married after signing your trust, you probably intended to provide for your new spouse, unless you said otherwise. This concept is sometimes called "revocation by operation of law," though that phrase is a bit misleading.
Your trust isn't voided. Instead, a specific statute steps in to fill the gap.
Under California Probate Code section 21610, a spouse left out of a trust executed before the marriage can claim:
- One-half of the community property belonging to the deceased spouse
- One-half of any quasi-community property
- A separate-property share equal to what they'd get under intestate succession, capped at half the separate property
This protection has important exceptions. It does not apply if:
- Your trust explicitly states you intended to exclude a future spouse
- You made another provision for them outside the trust
- They waived their rights in writing
Timing matters here. Courts distinguish between trusts signed before the marriage (where omission looks like an oversight) and trusts signed after (where omission looks intentional). That distinction can make or break a spouse's claim in probate court.
Revocable vs. Irrevocable Trusts: Why It Matters After Marriage
Not all trusts respond to marriage the same way, and the difference comes down to one word: revocable.
Revocable Trusts Adapt With Your Life
Most homeowners use a revocable living trust because it can change with them. Under California Probate Code section 15400, a trust is revocable by default unless the document says otherwise. Section 15402 lets you amend it using the same procedure as revocation. That means you can:
- Add your spouse as a beneficiary
- Update successor trustee designations
- Change property terms as your life changes
Irrevocable Trusts Stay Put
An irrevocable trust generally can't be modified once it's finalized, according to Nolo's overview of irrevocable trusts. Marriage has little to no direct legal effect on its terms. If you have one, getting married doesn't open the door to changes. People who want flexibility for life events like marriage usually choose a revocable structure instead.
Community Property vs. Separate Property: The Marriage Factor
Who owns an asset depends on where you got married and when you acquired it.
Separate property includes anything you owned before marriage or received individually as a gift or inheritance (California Family Code section 770).
Community property covers what you and your spouse acquire during the marriage while living in a community property state (California Family Code section 760).
Nine states follow community property rules, per the IRS's 2024 Publication 555:
- Arizona
- California
- Idaho
- Louisiana
- Nevada
- New Mexico
- Texas
- Washington
- Wisconsin
Here's the practical impact: assets you put into a trust before marriage typically stay separate property. Assets earned during the marriage may be community property regardless of what the trust document says, unless there's a valid transmutation agreement changing that character.
In California specifically, this gets complicated fast if a trust isn't properly funded. If a home purchased during marriage never gets retitled into the trust correctly, community property rules can override what the trust intended.
Does an Existing Trust Protect You If You Don't Update It?
Technically, yes. Practically, not always.
Your trust remains legally valid even if you never touch it after marriage. But "valid" doesn't mean "unchallengeable." An outdated trust that omits a new spouse can be contested in probate court under the omitted spouse statutes covered earlier.
That contest process defeats the entire point of having a trust:
- Litigation costs pile up fast
- Disputes can drag on for months or years
- In some cases, the estate ends up in full probate anyway
There's also a funding problem. Even a well-written trust doesn't protect assets that were never legally transferred into it.
If a home or bank account earned during marriage was never retitled, community property claims can override the trust's stated terms regardless of what the document says on paper.
How to Update Your Living Trust After Getting Married
Updating a trust after marriage is usually simpler and less expensive than starting over. Focus on these items:
- Amend the trust language: State clearly whether your spouse is included or intentionally excluded
- Update successor trustees: Many people still list a parent or sibling named before the wedding
- Revise beneficiaries: Align the trust with your current intentions, not your pre-marriage plan
- Weigh a prenup or postnup: Clarify separate versus community property when the trust alone cannot A Licensed Document Assistant can prepare the paperwork from your instructions. An LDA cannot advise you on whether to include or exclude a spouse, or on prenup strategy—those choices are yours, or an attorney's if the situation is complex. For California homeowners who already have a trust, an amendment is generally far less costly than a full rewrite. HomeTrust, operated by Marco Mariani (California LDA #231) in San Diego County, prepares amendments that update successor trustees, beneficiaries, and property provisions after marriage. Marco has prepared more than 10,000 California trusts since 1992. Most amendment and new-trust document preparation is completed in 1 to 3 business days. If you need a new trust instead:
- Individual trust package: starting at $409 / settlor plus recording and notary fees per Settlor
- Joint trust for couples: $618 plus notary and recording fees
Frequently Asked Questions
What happens if you have a trust and then get married?
Your trust generally remains valid, but omitted spouse laws in many states may grant your new spouse a share of the estate if the trust wasn't updated to reflect the marriage.
Does getting married automatically cancel a living trust?
No. Marriage doesn't cancel a trust outright, but it can trigger legal protections for a spouse who was left out of the document.
Can I keep my trust exactly as it was before marriage?
Possibly, if the trust clearly states your intent to exclude a future spouse. Courts scrutinize this language closely, so verify it still holds after you marry.
Is a living trust considered marital property in a divorce?
It depends. Assets in the trust may be separate or community property based on when and how they were acquired. A divorce may require dividing any community property portion.
Do I need a new trust after marriage, or can I amend my old one?
A revocable trust can typically be amended rather than recreated, which saves both time and cost compared to starting over.
How soon after marriage should I update my living trust?
As soon as possible. Waiting raises the risk of disputes, unintended distributions, and a later probate court challenge.
