What the rule says
California law protects spouses who marry into a relationship after the other spouse already has a will in place. Under California Probate Code §§ 21610–21612, when a person executes a will and later marries, the new spouse is entitled to a share of the deceased spouse's estate equal to what they would have received under intestacy — unless one of three statutory exceptions applies.
The omitted spouse takes:
- A one-half interest in the community property and quasi-community property that belonged to the decedent - A share of the decedent's separate property equal to what they would have received under intestate succession (one-third to all, depending on what other relatives survive)
This protection exists because the law presumes that a will executed before marriage did not anticipate the spouse and that the decedent likely would have provided for the new spouse if they had updated the will.
The three exceptions
The omitted-spouse share does not apply if any of the following is true:
1. The omission was intentional and the will or other evidence demonstrates that intent. A will that says "I am leaving nothing to any future spouse" or that names a specific future spouse and disinherits them satisfies this exception. 2. The decedent provided for the spouse outside the will. Life insurance, beneficiary designations on retirement accounts, joint titling of property, or transfers during life can all qualify, and the statute says the provision must appear from "statements of the decedent or from the amount of the transfer or other evidence." 3. The spouse waived the right to share in the estate through a valid written agreement — typically a premarital agreement or postmarital agreement. The waiver must meet the requirements of Cal. Probate Code §§ 140–147.
If any one of these applies, the spouse takes only what the will provides (which may be nothing).
What this means in practice
The rule protects a common situation: a person executed a will years before remarrying, never updated it, and then died without their current spouse appearing anywhere in the document. California treats this as an oversight and corrects it by giving the spouse an intestate share — unless evidence shows the omission was intentional or the spouse was provided for some other way.
The rule does not protect a current spouse who is named in the will but receives less than the intestate share would have given them. Omitted-spouse protection only addresses spouses who do not appear in the will at all (or who are mentioned only as "my future spouse" without a substantive provision).
Practical consequences:
- A surviving spouse who married into a household where the will pre-dates the marriage often qualifies for a substantially larger share than the will alone would provide. - An executor administering an estate must check the will's date against the marriage date and analyze whether one of the three exceptions applies before distributing. - Litigation can arise when the will is silent on intent and a beneficiary under the will argues that lifetime gifts or insurance proceeds satisfy the "provision outside the will" exception.
What you can do about it
The cleanest way to handle the issue is to update the will after marriage. A new will (or a codicil) executed after the marriage that addresses the spouse explicitly — whether by including or by deliberately disinheriting them — eliminates ambiguity.
If you do not want a future spouse to inherit, a premarital agreement that includes a written waiver of inheritance rights is the most reliable mechanism. A waiver embedded in a properly executed premarital or postmarital agreement is enforceable under California Probate Code §§ 140–147.
Who this affects most
This rule is most relevant for:
- Californians who marry without revisiting their estate plan - Blended families where adult children from a prior relationship may dispute the omitted-spouse share - Estates where the will pre-dates the marriage by a significant period and no clear evidence of intentional omission exists
The omitted-spouse rule is a default protection. Documenting your actual intent — whether to provide for the new spouse or not — replaces the default with your choice.
