Contesting a Will in California
The deadline, the grounds, the no-contest-clause risk, and your first step. Verified against the cited statute.
This is legal information, not legal advice. Contest-a-Will Navigator is a self-help research and document-preparation tool. It is not a law firm, does not represent you, and using it creates no attorney-client relationship. Will contests are litigation with strict, unforgiving deadlines and real risk. Verify every detail against your state's current statutes and court rules, and consult a licensed probate attorney before acting.
The deadline verified
⏰ 120 days after the will is admitted to probate
Once a will is admitted to probate, an interested person generally has 120 days from that order to file a Petition to Revoke Probate. Before the will is admitted, you can object at the probate hearing. Minors and incapacitated persons without a guardian get an extended window.
Missing a will-contest deadline almost always ends the case permanently, even when the will is genuinely defective. Treat the date as hard.
No-contest (in terrorem) clause in California
🛡️ Enforced only against a direct contest brought WITHOUT probable cause
California enforces a no-contest clause against a "direct contest" only when it is brought without probable cause. Probable cause exists if the facts you know at filing would make a reasonable person believe the contest has a reasonable likelihood of success. A good-faith contest backed by real evidence generally does not trigger forfeiture — but this is a fact-specific call best confirmed with a probate litigator.

Grounds to contest a will in California
California recognizes the same core grounds used across the U.S. You need a valid legal ground — being unhappy with your share is not enough.
- 🧠 Lack of testamentary capacity — The will-maker did not understand what they owned, who their natural heirs were, or the act of making a will.
- 🕸️ Undue influence — Someone in a position of trust overpowered the will-maker's free choice.
- 🎭 Fraud — The will-maker was deceived into signing or into its terms.
- 📝 Improper execution / formalities — The will was not signed and witnessed the way state law requires.
- ✍️ Forgery — The signature or the document itself is fake.
- 🗑️ Revocation / a later will — A newer valid will or codicil replaced this one, or the will was revoked.

Who can contest & the first step
Standing: only an "interested person" — typically an heir who would inherit if the will were invalid, or a beneficiary under a prior will — can contest in California.
File where: Superior Court of California (Probate Division) for the county where the estate is being administered
First step: File objections at the probate hearing if the will is not yet admitted, or a Petition to Revoke Probate (with written grounds) within 120 days if it has been admitted.
🚨 Get a probate attorney before you file if any of these are true
- The estate is large or complex (real estate in several states, a business, trusts).
- There is a no-contest clause AND your state may enforce it — losing can mean losing your inheritance.
- Your grounds are capacity or undue influence (these need medical experts and discovery).
- You suspect forgery (you will need a handwriting/questioned-document expert).
- The deadline is near, unclear, or may have passed.
- Honestly: almost every contested will involves litigation. A free or low-cost consult is worth it before you commit.
