How to Contest a Will in California

Something feels wrong. Maybe the will your mother left behind cuts out the child who spent years caring for her. Maybe your father, who spent decades building a business, suddenly left everything to someone he met only months before he died. Or maybe the signature on the document just does not look right. Whatever raised the alarm, one thing is clear: you are not ready to accept the will as written without asking some hard questions.

You are not alone. Will contests are more common than people expect, and California law provides legitimate pathways to challenge a will that does not reflect a testator’s true wishes. But this process has strict rules, tight deadlines, and real consequences for getting it wrong. This guide walks you through what contesting a will in California actually involves, from whether you have standing to sue to what happens if the matter goes to trial.

What Does It Mean to Contest a Will in California?

Contesting a will means filing a formal legal challenge asking the court to declare the will, or a portion of it, invalid. It is not the same as disputing how an executor is managing an estate, and it is not a complaint about receiving less than you expected. A will contest goes to the heart of whether the document itself is legally valid.

Will contests take place inside the probate process. They are adversarial proceedings where evidence is gathered, witnesses are deposed, and a judge ultimately decides whether the will stands. California courts presume that a will is valid, which means the burden of proof generally falls on the person challenging it. This is a serious undertaking that requires solid factual support from the outset.

Who Can Contest a Will in California?

Not everyone has the right to bring a will contest. Under California Probate Code § 48, only an “interested person” has legal standing to file. California courts have further held, in cases such as Estate of Weber, 229 Cal.App.3d 22 (1991), that a contestant must have a pecuniary interest in the proceedings, meaning a real financial stake in the outcome.

Interested persons who typically have standing include:

  • Beneficiaries named in the current will
  • Beneficiaries named in a prior version of the will
  • Heirs who would inherit under California’s intestate succession laws if no valid will existed, such as a spouse, children, siblings, or parents
  • Creditors with claims against the estate

People who were financially dependent on the deceased may have standing only if they qualify as heirs, beneficiaries, or creditors. Being a close friend, a longtime neighbor, or even a devoted caregiver does not automatically give you standing. If you do not fall into one of the above categories, the court will likely dismiss your contest regardless of your personal connection to the deceased.

What Are the Legal Grounds to Contest a Will in California?

California courts recognize specific legal grounds on which a will can be challenged. The burden of proving those grounds at trial is governed by Probate Code § 8252. General dissatisfaction with the outcome is not sufficient. The recognized grounds are:

Lack of Testamentary Capacity

For a will to be valid, the person creating it, the testator, must have been of sound mind at the time of signing. California Probate Code § 6100.5 sets out the mental requirements. The testator must have been able to:

  • Understand the nature of making a will
  • Know the general extent of their property
  • Recognize who their natural heirs are
  • Understand how the will distributes property

Medical records showing dementia, psychosis, or similar conditions around the time the will was signed can be powerful evidence. Advanced age, forgetfulness, or unusual behavior alone does not establish incapacity under California law.

Undue Influence

This is one of the most frequently raised grounds in California will contests. Undue influence occurs when someone in a position of trust, such as a caretaker, a romantic partner, or a new acquaintance, uses that relationship to pressure or manipulate the testator into changing their will so that it reflects the influencer’s wishes rather than the testator’s own.

California defines undue influence as “excessive persuasion that causes another person to act or refrain from acting by overcoming that person’s free will and results in inequity” (Welfare and Institutions Code § 15610.70, incorporated by Probate Code § 86). A presumption of undue influence, which shifts the burden of proof to the alleged influencer, arises when the challenger shows that the influencer had a confidential relationship with the testator, actively participated in procuring the will’s preparation or execution, and would benefit unduly from the result. Rice v. Clark (2002) 28 Cal.4th 89, 96–97.

Fraud

A will procured by fraud is invalid. This covers situations where the testator was deceived into signing a document, for example, told it was something other than a will, or where the testator was given false information that directly changed what the will said.

Improper Execution

California has formal requirements for signing a will. Under Probate Code § 6110, a valid will must be in writing, signed by the testator (or by another person in the testator’s presence and at their direction), and witnessed by at least two people who were both present at the same time and who understood that they were witnessing the execution of a will. A will that fails to meet these requirements can be invalidated on procedural grounds alone.

The exception is a holographic will, one entirely in the testator’s own handwriting and signed by them, which does not require witnesses under Probate Code § 6111. But even holographic wills can be contested on capacity or undue influence grounds.

Forgery

If someone fabricated the testator’s signature or altered the document after it was signed, those portions, or the entire will, may be invalidated. Forensic document analysis is often used in these cases.

Revocation

A previously revoked will is not valid. Under Probate Code § 6120, a will can be revoked by a later will, by a written revocation, or by physical destruction with the intent to revoke. If someone admits a revoked will to probate, that is a proper ground for contest.

What Are the Deadlines for Contesting a Will in California?

The timing rules in California will contests are unforgiving. Missing a deadline can permanently end your right to challenge the will, regardless of how strong your case might be.

Before Probate Is Opened

If a petition to admit the will to probate has been filed but the court has not yet granted probate, any interested person can file a written objection before the hearing date. Under Probate Code § 8003, petitioners must give at least 15 days’ notice before the hearing. In many California counties, hearings are typically scheduled 30 to 60 days after the petition is filed, although timing varies by county. Once the will is admitted at the hearing, the contest window shifts to the post-probate deadline. Do not wait for a “better moment” because if you miss the hearing without filing a written objection, that opportunity is gone.

After Probate Is Granted

Once the court admits the will to probate, Probate Code § 8270 gives interested persons 120 days to file a petition asking the court to revoke that order. The 120-day clock begins on the date the will is admitted to probate. This deadline does not stop for personal circumstances, and it does not get extended for any reason other than very narrow exceptions allowed by statute. It simply expires.

What Is the Process for Contesting a Will in California?

Once you have confirmed standing, grounds, and timing, the procedural steps for a will contest generally go as follows:

  1. File a written objection or petition with the probate court in the county where the deceased lived. The document must clearly state the legal grounds for your challenge.
  2. Serve a summons on all required parties. Under Probate Code § 8250 for pre-probate contests or § 8271 for post-probate contests, you must serve all heirs, beneficiaries, and the personal representative. Respondents generally have 30 days to file a written response after service.
  3. Conduct discovery. Both sides gather evidence through depositions, medical record subpoenas, financial records, witness interviews, and document analysis. This is often the most time-consuming phase.
  4. Attend a mandatory settlement conference. California courts require parties to attempt settlement before going to trial. Many will contests resolve at this stage.
  5. Proceed to trial if no settlement is reached. The proponent of the will bears the burden of proving it was properly executed, while the contestant bears the burden on grounds such as incapacity, undue influence, or fraud under Probate Code § 8252(a).
  6. Receive a court ruling. The court will either admit the will to probate, reject it, or invalidate specific provisions. If the will is rejected, the estate passes under a prior valid will or, if none exists, according to California’s intestate succession laws under Probate Code § 6400 et seq.

 

What About No-Contest Clauses?

Many California wills contain no-contest clauses, provisions designed to disinherit any beneficiary who challenges the will. These clauses are enforceable in California, but only within limits set by Probate Code § 21311. A no-contest clause can only be triggered against a “direct contest” filed without probable cause.

What does probable cause mean here? It means that at the time you file, the facts you know would lead a reasonable person to believe there is a realistic chance the court will grant the relief you are requesting. If you have solid evidence, such as medical records showing incapacity, witness statements about pressure, or forensic analysis of a signature, you can file a contest despite the no-contest clause without risking disinheritance. The clause is meant to stop frivolous challenges, not well-founded ones.

Worth noting, the same principle applies in trust contests. In Meiri v. Shamtoubi (2022) 81 Cal.App.5th 606, a beneficiary who waited too long to file her trust contest lost her inheritance, not because her claims were found to be without merit, but because the court found her filing was a direct contest without probable cause under the trust’s no-contest clause. It is a sharp reminder that timing and probable cause matter together, not just separately.

Key Takeaways

  • You must have legal standing, meaning a financial interest in the estate, to file a will contest in California.
  • You must have valid legal grounds, such as lack of capacity, undue influence, fraud, or improper execution.
  • Deadlines are strictly enforced. Once a will is admitted to probate, you generally have only 120 days to file a contest under California Probate Code § 8270.
  • Many wills include no-contest clauses, but California limits their enforcement under Probate Code § 21311. A well-supported contest filed with probable cause is protected.
  • A will contest is a formal legal proceeding, not simply telling the court you disagree with the outcome.

Frequently Asked Questions

Can a child contest a parent’s will in California?

Yes. A child who would inherit under California’s intestate succession laws has standing to contest a parent’s will. The child must still have valid legal grounds. Simply being left out of the will is not sufficient on its own.

How much does it cost to contest a will in California?

Will contests can be expensive. Costs include attorney fees, court filing fees, deposition costs, and fees for medical or forensic witnesses. The total depends heavily on how contested the matter is and whether it settles before trial. Many will contest attorneys handle these cases on a contingency or hybrid fee basis.

Can a will be contested after assets are distributed?

It becomes significantly more complicated once distribution has occurred. In most cases, once the 120-day window closes and assets are distributed, recovery requires separate civil litigation. This is why acting quickly matters so much.

What happens if a will contest is successful?

If the court invalidates the will, the estate passes either under a prior valid will or, if none exists, according to California’s intestate succession laws under Probate Code § 6400 et seq. The court may also invalidate specific provisions while leaving the rest of the will intact.

Do I need an attorney to contest a will in California?

Technically, no, but practically, yes. Will contests involve procedural rules, evidentiary standards, and statutory deadlines that are difficult to manage without legal training. A missed deadline or a poorly drafted petition can end your case before it has a chance to be heard.

What if the will is part of a living trust?

Many California estates are administered through revocable living trusts rather than through probate. If the deceased used a trust, you may need to contest the trust instrument rather than or in addition to the will. Trust contests follow different procedural rules, including different notice requirements and deadlines. The grounds for challenging a trust, however, are often the same.
