✓ Verified September 2026

To contest a will in California, you file in the probate court within a fixed window and prove one of a short list of legal grounds. This guide gives the California answer in plain English, and it starts with the deadline, because that is the fact that ends more cases than any other. All facts are from California law, verified as of September 2026.

Contest a Will in California: At a Glance

Here are the California facts that decide whether you can contest a will in California:

Deadline to contest 120 days after the will is admitted to probate to file a petition to revoke probate (Cal. Prob. Code § 8270(a)). Before admission, a contest may be filed at any time up to and including the hearing on the petition for probate (Cal. Prob. Code § 8250(a)). Exception: a person who was a minor or was incompetent with no guardian or conservator when the will was admitted may petition at any time before entry of the order for final distribution (Cal. Prob. Code § 8270(b)). Once a summons on a revocation petition is served, respondents have 30 days to answer (Cal. Prob. Code § 8271).
What starts the clock Two separate clocks. (1) Pre-probate contest: the clock runs to the hearing date on the petition for probate — the contest must be filed at or before that hearing (§ 8250(a)). (2) Post-probate contest: the 120 days runs from the date the court enters the order admitting the will to probate (§ 8270(a)) — not from the date of death, not from notice of the death, and not from the Notice of Petition to Administer Estate. Note that § 8270 relief is unavailable to a person who was already a party to a will contest or who had actual notice of a will contest in time to have joined it.
Who can contest Any “interested person” (Cal. Prob. Code §§ 8250(a), 8270(a)), defined at Cal. Prob. Code § 48 as an heir, devisee, child, spouse, registered domestic partner, creditor, beneficiary, or any other person having a property right in or claim against the estate that may be affected by the proceeding; any person having priority for appointment as personal representative; and a fiduciary representing an interested person. This includes intestate heirs who would take if the will fell, beneficiaries under a prior will who would receive more if the current will were set aside, and named executors. Yes — creditors of the estate are expressly within § 48. The court may determine standing according to the particular purposes of, and matter involved in, any proceeding (§ 48(b)).
No-contest clause YES, but only narrowly — enforced with a probable-cause exception. Cal. Prob. Code § 21311(a) provides a no contest clause shall be enforced ONLY against: (1) a direct contest brought without probable cause; (2) a pleading challenging a transfer of property on the ground it was not the transferor’s property at the time of transfer (only if the clause expressly so provides); and (3) the filing of a creditor’s claim or prosecution of an action based on it (only if the clause expressly so provides). “Probable cause exists if, at the time of filing a contest, the facts known to the contestant would cause a reasonable person to believe that there is a reasonable likelihood that the requested relief will be granted after an opportunity for further investigation or discovery” (§ 21311(b)). “Direct contest” is defined at § 21310(b) (forgery, lack of due execution, lack of capacity, menace/duress/fraud/undue influence, revocation, disqualification of a beneficiary under §§ 6112, 21350, or 21380). The current scheme applies to instruments that became irrevocable on or after January 1, 2001 (§ 21315). California also eliminated the former pre-filing “safe harbor” declaratory relief procedure.
What the filing is called Before the will is admitted: a written “Contest of Will” / “Objection to Probate of Will” filed with the court, stating the objections in writing and signed (Cal. Prob. Code § 8250(a)); the contestant may also file a Demurrer or Motion to Strike (§ 8251). After admission: a “Petition to Revoke Probate of Will,” which must include written grounds of opposition, filed under Cal. Prob. Code § 8270; a summons then issues to the personal representative and to the known heirs and devisees (§ 8271). Both are filed in the probate department of the Superior Court where the estate is being administered. Related Judicial Council forms: DE-111 (petition for probate) and DE-160/DE-161; there is no statewide Judicial Council form for the contest itself, so it is a pleading prepared by the party.
Court The Superior Court of California for the county of the decedent’s domicile at death (or, for a non-resident, the county where property is located) — specifically the Probate Department/Division of that Superior Court (Cal. Prob. Code §§ 7050, 7051, 7052). There is no separate “surrogate’s court” in California; probate is a department of the unified Superior Court.
Jury trial NO. Cal. Prob. Code § 825: “Except as otherwise expressly provided in this code, there is no right to a jury trial in proceedings under this code.” Cal. Prob. Code § 8252(b) directs that “The court shall try and determine any contested issue of fact that affects the validity of the will.” California will contests are bench trials decided by a probate judge. (California abolished the former statutory jury right for will contests; § 825 was added by Stats. 1999, ch. 175, § 1, effective January 1, 2000.)
Typical cost UNVERIFIED as a total case range — no official California court or State Bar publication states a typical total. Verified component figures: California trust and probate litigation attorneys commonly bill hourly, with reported rates from 300 to 1500 per hour depending on county and experience, and contingency fee agreements in will and trust contests commonly reported in the 30 to 50 percent range of the amount recovered. Note these are private-firm reported figures, not government data, and California attorney fees are fully negotiable. Separately, statutory compensation for ordinary services in the underlying probate (not the contest) is fixed by Cal. Prob. Code § 10810 at 4 percent of the first 100000 of the estate’s appraised value, 3 percent of the next 100000, 2 percent of the next 800000, 1 percent of the next 9000000, and 0.5 percent of the next 15000000; a will contest is “extraordinary services” compensated separately at the court’s discretion under Cal. Prob. Code § 10811. Anyone budgeting a contest should get a written fee estimate from a licensed California attorney.

The Deadline to Contest a Will in California

⚠ Deadline to contest a will in California: 120 days after the will is admitted to probate to file a petition to revoke probate (Cal. Prob. Code § 8270(a)). Before admission, a contest may be filed at any time up to and including the hearing on the petition for probate (Cal. Prob. Code § 8250(a)). Exception: a person who was a minor or was incompetent with no guardian or conservator when the will was admitted may petition at any time before entry of the order for final distribution (Cal. Prob. Code § 8270(b)). Once a summons on a revocation petition is served, respondents have 30 days to answer (Cal. Prob. Code § 8271).. The clock starts at Two separate clocks. (1) Pre-probate contest: the clock runs to the hearing date on the petition for probate — the contest must be filed at or before that hearing (§ 8250(a)). (2) Post-probate contest: the 120 days runs from the date the court enters the order admitting the will to probate (§ 8270(a)) — not from the date of death, not from notice of the death, and not from the Notice of Petition to Administer Estate. Note that § 8270 relief is unavailable to a person who was already a party to a will contest or who had actual notice of a will contest in time to have joined it.. Missing it usually ends the case regardless of how strong the grounds are.

The window is short in some states and long in others, and it is measured from a specific event rather than from the day you learned about the will. That is why the first thing to find out is the date the will was admitted and whether you received formal notice. If the deadline has not run, everything else on this page is available to you.

If it has, the remaining options are narrow and usually involve proving you never got the notice the law required.

Grounds to Contest a Will in California

Cal. Prob. Code § 8252(a) lists the grounds the contestant must prove: lack of testamentary intent, lack of testamentary capacity (§ 6100.5), undue influence, fraud, duress, mistake, and revocation (§ 6120). Menace is also a ground (§ 6104 — a will or any part procured by duress, menace, fraud, or undue influence is invalid as to that part).

Improper execution / lack of due execution under § 6110 (signed by the testator and witnessed by two persons present at the same time) is contested by opposing the proponent’s proof, since the proponent bears that burden. Forgery is litigated as lack of due execution / fraud. Common companion claims: financial elder abuse and the presumptions of fraud or undue influence under §§ 21380–21392.

Who has to prove what: Split by issue under Cal. Prob. Code § 8252(a): the PROPONENT of the will has the burden of proof of due execution; the CONTESTANT has the burden of proof of lack of testamentary intent or capacity, undue influence, fraud, duress, mistake, or revocation. Standard is preponderance of the evidence (Cal. Evid. Code § 115 default).

Presumption shifting: under California case law a presumption of undue influence arises, shifting the burden to the proponent, when the contestant shows (1) a confidential relationship between the alleged influencer and the testator, (2) the influencer’s active participation in procuring the will’s preparation or execution, and (3) an undue benefit to the influencer. Separately, Cal. Prob.

Code § 21380 creates a statutory presumption of fraud or undue influence for donative transfers to the drafter of the instrument, a care custodian of a dependent adult transferor (if executed during the care period or within 90 days before or after it), a fiduciary who transcribed the instrument, and persons related to or associated with them.

That presumption is rebuttable only by CLEAR AND CONVINCING evidence (§ 21380(b)) — and is CONCLUSIVE (not rebuttable at all) as to a transfer to the drafter or persons related to/associated with the drafter. A beneficiary who fails to rebut bears all costs of the proceeding including reasonable attorney’s fees (§ 21380(d)). “Undue influence” is defined by Cal. Welf. & Inst. Code § 15610.70, incorporated into probate matters by Cal.

Prob. Code § 86.

Who Can Contest a Will in California

Any “interested person” (Cal. Prob. Code §§ 8250(a), 8270(a)), defined at Cal. Prob. Code § 48 as an heir, devisee, child, spouse, registered domestic partner, creditor, beneficiary, or any other person having a property right in or claim against the estate that may be affected by the proceeding; any person having priority for appointment as personal representative; and a fiduciary representing an interested person.

This includes intestate heirs who would take if the will fell, beneficiaries under a prior will who would receive more if the current will were set aside, and named executors. Yes — creditors of the estate are expressly within § 48. The court may determine standing according to the particular purposes of, and matter involved in, any proceeding (§ 48(b)).

Being unhappy with the will is not standing; losing something because of it is. Check the earlier will and the intestate rules for California before filing, because they decide whether you are an interested person.

No-Contest Clauses in California

YES, but only narrowly — enforced with a probable-cause exception. Cal. Prob.

Code § 21311(a) provides a no contest clause shall be enforced ONLY against: (1) a direct contest brought without probable cause; (2) a pleading challenging a transfer of property on the ground it was not the transferor’s property at the time of transfer (only if the clause expressly so provides);

and (3) the filing of a creditor’s claim or prosecution of an action based on it (only if the clause expressly so provides).

“Probable cause exists if, at the time of filing a contest, the facts known to the contestant would cause a reasonable person to believe that there is a reasonable likelihood that the requested relief will be granted after an opportunity for further investigation or discovery” (§ 21311(b)).

“Direct contest” is defined at § 21310(b) (forgery, lack of due execution, lack of capacity, menace/duress/fraud/undue influence, revocation, disqualification of a beneficiary under §§ 6112, 21350, or 21380). The current scheme applies to instruments that became irrevocable on or after January 1, 2001 (§ 21315). California also eliminated the former pre-filing “safe harbor” declaratory relief procedure.

The Steps to Contest a Will in California

Step one is the deadline check above. Step two is evidence: the medical records around the signing date, the names of the witnesses, the drafting lawyer’s file, and the financial records that show who benefited. Step three is the filing — Before the will is admitted: a written “Contest of Will” / “Objection to Probate of Will” filed with the court, stating the objections in writing and signed (Cal. Prob.

Code § 8250(a)); the contestant may also file a Demurrer or Motion to Strike (§ 8251). After admission: a “Petition to Revoke Probate of Will,” which must include written grounds of opposition, filed under Cal. Prob. Code § 8270; a summons then issues to the personal representative and to the known heirs and devisees (§ 8271).

Both are filed in the probate department of the Superior Court where the estate is being administered. Related Judicial Council forms: DE-111 (petition for probate) and DE-160/DE-161; there is no statewide Judicial Council form for the contest itself, so it is a pleading prepared by the party.. Step four is discovery and, in most cases, a settlement conference; the small minority that reach trial are decided by the judge.

Settling Instead of Fighting

YES. California permits negotiated resolution of will contests. Mediation and other ADR are widely used in California probate departments, and several superior courts operate probate ADR or settlement conference programs; under Breslin v. Breslin (2021) 62 Cal.App.5th 801, a probate court may order interested parties to mediation and parties who receive notice and fail to participate may be bound by the result.

A mediated settlement is enforceable if it satisfies Cal. Code Civ. Proc. § 664.6 (written agreement signed by the parties, or an oral stipulation before the court). Compromise or settlement of a claim or matter in the estate by the personal representative requires court authorization or approval under Cal. Prob. Code §§ 9830–9839.

Where a settlement affects a minor or an incapacitated or unborn/unascertained beneficiary, court approval is required under Cal. Prob. Code §§ 3500–3505 and the guardian ad litem provisions of Cal. Prob. Code § 1003. Family settlement agreements among all competent adult interested parties are recognized, but distributions departing from the will still need to be reflected in the court’s distribution order.

Other California rules: Several. (1) NO ante-mortem/pre-death will validation — the California Probate Code contains no living-probate procedure, so a will can only be challenged after the testator’s death. (2) NO contemporaneous self-proving affidavit at execution, unlike many states; instead, an uncontested will may be proved on the evidence of a single subscribing witness, including by affidavit of a subscribing witness with a photographic copy of the will attached (Cal.

Prob. Code § 8220), and if no subscribing witness is available the will may be proved by proof of handwriting plus other evidence (§ 8221). Once a contest is filed, that shortcut is unavailable and live proof of due execution is required.

(3) Harmless error rule — a will not executed in compliance with § 6110(c)(1) is still valid if the proponent establishes by CLEAR AND CONVINCING evidence that the testator intended the document to be the will at the time of signing (Cal. Prob. Code § 6110(c)(2)). (4) Holographic wills are valid without witnesses if the signature and material provisions are in the testator’s own handwriting (Cal. Prob. Code § 6111).

(5) California Statutory Will — a fill-in form will authorized by Cal. Prob. Code §§ 6240–6243. (6) Interested witness presumption — a devise to a subscribing witness creates a rebuttable presumption of duress, menace, fraud, or undue influence (Cal. Prob. Code § 6112(c)); the will itself remains valid. (7) Capacity standard is codified and comparatively low (Cal. Prob. Code § 6100.5), and the Due Process in Competence Determinations Act (Cal.

Prob. Code §§ 810–812) supplies the general mental-function framework. (8) Statutory disqualification of certain beneficiaries under §§ 21380–21392, with the conclusive presumption against drafters noted above. (9) No safe-harbor declaratory relief procedure to test a no contest clause before filing — repealed effective January 1, 2010.

(10) An action to establish a claim based on financial elder abuse can survive independently of the will contest and may reach a defendant personally.

The Evidence That Wins or Loses a Will Contest

Capacity cases turn on the weeks around the signing: the medical chart, prescriptions, a dementia diagnosis, and what the drafting lawyer and the witnesses saw that day. A will signed in a lawyer’s office with two disinterested witnesses and a self-proving affidavit is hard to attack; a will signed at a kitchen table with the main beneficiary present is not.

Undue influence cases turn on the relationship — who drove the parent to the appointment, who chose the lawyer, who was in the room, and whether the new will departed sharply from earlier ones and from what the parent said to other people.

Improper execution is the narrowest ground and the cleanest: California sets exact witness and signature rules, and a will that misses them fails regardless of what the signer intended. Before you contest a will in California, gather the prior wills, the medical releases, and the names of everyone at the signing.

Most of that evidence has to be requested formally once the case is filed, and the deadline does not wait for it.

What to Expect When You Contest a Will in California

A will contest is a lawsuit about the document, not about fairness. When you contest a will in California, the court asks whether the person who signed it had capacity, signed it freely, and signed it correctly. It does not ask whether the split was reasonable. That is why the strongest cases rest on medical records and witness accounts from the weeks around the signing.

Most families who contest a will in California settle. Courts encourage it, many states have family settlement rules that let the heirs agree to a different division, and a settlement avoids the cost and delay of trial. The deadline, the grounds, and the no-contest clause above are the three facts that set your bargaining position before any of that begins.

You don’t have to do this alone

If you are settling a loved one’s estate in California, your state’s probate court self-help center and free legal-aid offices can walk you through the process at no cost. For an active probate or a deadline, talk to a licensed probate attorney in your state.

Key Takeaways: Contest a Will in California

  • The deadline is everything: the window to contest a will in California closes on a fixed schedule, and the court cannot reopen it for a late but valid claim.
  • Grounds are specific: you contest a will in California on capacity, undue influence, fraud, duress, or bad execution, never on unfairness alone.
  • Standing first: only an interested person can contest a will in California; check whether you inherit under the prior will or the intestate rules.
  • Read the no-contest clause: whether the state enforces it decides how much risk it takes to contest a will in California.
  • Evidence is medical and financial: records, witnesses to the signing, and the drafting lawyer’s file decide most cases when you contest a will in California.
  • Settlement is common: most families who contest a will in California settle before trial, often through the state’s family settlement rules.
  • Find the admission date: the day the will was admitted is the day the clock to contest a will in California usually starts.

  • Notice defects are a lifeline: if you never got the required notice, you may still contest a will in California after the ordinary deadline.
  • Self-proved wills are harder: a will with a notarized witness affidavit raises the bar to contest a will in California on execution grounds.

  • Mediation is usually offered: many courts require a settlement conference before anyone who chooses to contest a will in California sees a judge.

Quick Answers: Contest a Will in California

What does it cost to contest a will in California?

Contested cases commonly run into five figures, and some lawyers take strong cases on contingency. Compare the cost to the amount you would gain if the will fails.

Can you contest a will in California after probate closes?
