Contesting a Will in California

The 120-Day Filing Window

California Probate Code § 8270 gives you 120 days from the date the court admits a will to probate to file a will contest petition. Missing that window can bar your challenge. If you did not receive required notice, a separate notice-based rule may affect your deadline; get advice promptly rather than assuming the standard period is extended.

This is tighter than many states. Texas allows two years. California gives you four months from admission to probate; check promptly whether any notice-based rule affects your deadline.

The practical implication: if a parent or family member has recently died and you suspect something is wrong with their will, start monitoring the probate court in the county where they lived. You can search the Los Angeles, San Francisco, or relevant county superior court's online probate case index for free.

Who Has Standing to Contest

California restricts will contests to people with a direct financial stake in the outcome. You qualify if you are:

• Named as a beneficiary in the current will or a prior version
• An heir who would inherit under California's intestacy laws if the will were thrown out
• A creditor of the estate with an outstanding debt

Friends, non-adopted stepchildren, and distant relatives who wouldn't inherit under intestacy generally cannot bring a challenge. This is consistent with most states, but California courts enforce standing requirements aggressively — the court will dismiss your petition before reaching the merits if you can't show a pecuniary interest.

Legal Grounds That Actually Work

California recognizes four primary grounds for contesting a will:

Lack of testamentary capacity. The testator must have understood the nature of the will, known the extent of their property, and recognized the people who would naturally expect to inherit. A dementia diagnosis alone doesn't invalidate a will — California courts recognize lucid intervals, meaning someone with Alzheimer's could execute a valid will during a period of clarity. You need medical records from around the exact date of signing, not just a general diagnosis.

Undue influence. California law does not treat every beneficiary witness as automatically invalidating a will. An interested witness can trigger a statutory presumption affecting that gift, and the result depends on the will's witnesses and whether the presumption is rebutted. This is particularly relevant in caregiver situations where a late-life companion or aide inherits most of the estate.

Fraud or forgery. Someone deceived the testator about the document's contents or forged the signature. Handwriting evidence may be used to examine the original document — so preserving the physical will matters.

Improper execution. California requires the testator's signature and two witnesses who watched the signing or heard the testator acknowledge it. Unlike some states, California does not require notarization for a standard witnessed will.

California's No-Contest Clause Rules

This is where California differs significantly from states like Florida (where no-contest clauses are unenforceable) or Indiana.

Under Probate Code § 21311, California enforces no-contest clauses — but only for three specific types of challenges: direct contests to the validity of the instrument, challenges to property transfers, and challenges to the creation of a trust. And even then, the clause is only enforceable if the contestant lacks "probable cause."

If you have probable cause — meaning a reasonable person in your position would believe the grounds for your challenge are supported by credible evidence — the no-contest clause cannot be used to strip your inheritance. This is a significant protection, but it means you need to build your evidentiary case before filing, not after.

What a California Will Contest Costs

California follows the American Rule: each side pays their own attorney's fees. Estate litigation attorneys in the state typically charge $350–$700 per hour, with initial retainers of $5,000–$15,000 depending on the complexity of the case. A straightforward contest that settles at mediation might cost $15,000–$30,000 in total legal fees. A case that goes to trial can run $50,000–$150,000 or more.

One exception to the each-side-pays rule: if your challenge benefits the estate as a whole (for example, by removing a corrupt executor or exposing a forged will), the court can order your fees paid from the estate.

The Mediation Step

California courts can order mediation before a will contest proceeds to trial. When the court orders it, parties must participate as directed. Mediation can resolve disputes at a fraction of trial costs.

Even without a court order, voluntary mediation is worth pursuing early. A skilled probate mediator can help families reach a compromise that preserves relationships and avoids the public exposure that comes with courtroom litigation — probate filings are public record in California.

Community Property Complications

California is a community property state, which adds a layer of complexity to will contests. A surviving spouse automatically owns half of all community property regardless of what the will says. The will can only dispose of the decedent's separate property and their half of community property.

This means a surviving spouse challenging a will may actually have stronger standing than in common-law property states. If the will attempts to give away community property that the surviving spouse rightfully owns, that provision is void on its face — no will contest needed for that portion.
