How to Contest a Will in California

How to contest a will in California: the grounds, who has standing, the deadline after a will is admitted, care custodian rules, and no-contest clauses.

By Settled Editorial

A will contest is a formal legal challenge to a will after a family member believes the document does not reflect the decedent's real wishes. Contesting a will in California is possible, but it is not a way to reargue how someone chose to divide their property. The challenge has to rest on a specific legal ground, the person bringing it has to have standing, and the window to act can be short. This guide covers the grounds, who can file, where and when, the special California rules for caregivers and drafters, no-contest clauses, and what the process involves.

Most California wills are never contested. But when the circumstances raise real concern, a caregiver who appeared late and took most of the estate, a signing during serious illness, or a signature that does not look right, a contest may be the right path. If you are weighing one, Settled's free California estate assessment can help you organize the facts before you talk to a lawyer.

What a Will Contest Is (and Is Not)

A will contest asks the court to declare that the will, or part of it, is invalid. If the challenge succeeds, the contested will is set aside, and the estate passes either under an earlier valid will or, if there is none, under California's intestate succession rules. A contest is the wrong tool when the real complaint is that you expected more, that you dislike the distribution, or that the personal representative is administering the estate poorly. That last problem is handled by objecting to the representative or the accounting, not by attacking the will. A contest often turns on whether California's signing rules were followed; for the full requirements, see the California will requirements guide.

Who Can Contest a Will in California

Only an interested person can contest a will, meaning someone with a financial stake, a person who would inherit more if the will were thrown out. The most common contestants are:

  • Heirs at law. People who would inherit under California's intestate succession statute if there were no valid will. Under the California Probate Code, that group starts with the surviving spouse or registered domestic partner and children, then extends to parents, siblings, and more distant relatives depending on who survives.
  • Beneficiaries under a prior will. If an earlier will left you more than the current one, you have a stake in setting the later will aside.
  • Beneficiaries named in the contested will, usually when an earlier document treated them better.

Friends, distant relatives who would not inherit under intestacy, and charities not named in any version of the will generally lack standing. The test is simple: would you be better off financially if the will were declared invalid? If not, the court will not hear your challenge.

The Grounds for Contesting a Will

California recognizes a handful of grounds for invalidating a will. The person bringing the contest usually carries the burden of proof. A will admitted to probate is presumed valid, and the contestant has to overcome that presumption with evidence. Vague suspicion is not enough.

1. Lack of Testamentary Capacity

California requires the testator to be of sound mind when the will is signed. Sound mind means the testator understood, at the moment of signing:

  1. That they were making a will to dispose of their property at death
  2. The general nature and extent of what they owned
  3. The people who would naturally inherit from them, such as a spouse and children
  4. How the will distributed the property among those people

Capacity is measured at the exact time of signing, not before or after. A diagnosis of dementia does not automatically prove incapacity, because a person with cognitive decline can have a lucid interval and validly sign during it. To win on this ground, a contestant usually relies on medical records from around the signing date, testimony from doctors and caregivers, and observations from people who saw the testator near that time.

2. Undue Influence

Undue influence is the most commonly alleged ground and one of the hardest to prove. It applies when someone in a position of trust used pressure or control that overpowered the testator's free will, so the will reflects the influencer's wishes rather than the testator's own. Ordinary persuasion, even forceful persuasion, is not enough.

California statute defines undue influence as excessive persuasion that overcomes another person's free will and results in inequity, and it lists factors a court weighs, including the victim's vulnerability, the influencer's apparent authority, the tactics used, and whether the outcome was inequitable. (Source: Welf. & Inst. Code section 15610.70.) In practice, courts also look for a confidential relationship between the testator and the beneficiary, combined with activity by that beneficiary in getting the will made and a result that favors them.

Common red flags include a caregiver or new companion who appeared shortly before the will changed, a testator isolated from family, an unexplained shift from an earlier estate plan, and a beneficiary who chose the drafting attorney or sat in on the signing.

3. Fraud, Forgery, or Duress

Fraud means the testator was deliberately deceived in a way that changed the will. Two forms come up: fraud in the execution, where the testator was tricked about what the document was (told they were signing a power of attorney when it was actually a will), and fraud in the inducement, where false information changed a gift (a lie that a child had abandoned or stolen from them). Forgery is a separate claim that the signature on the will is not the testator's, or that the document was fabricated, and it usually requires a forensic document examiner to compare the disputed signature against known samples. Duress covers threats or coercion that force the testator to sign against their will.

4. Improper Execution

A California will is only valid if it was signed the way the Probate Code requires. A formal witnessed will must be in writing, signed by the testator (or by someone else in the testator's presence and at the testator's direction), and signed by at least two witnesses, each of whom was present at the same time and witnessed the signing or the testator's acknowledgment of the will. (Source: Cal. Prob. Code sections 6100-6113.) California does recognize a holographic will, one whose material provisions and signature are in the testator's own handwriting, even without witnesses, so an unwitnessed handwritten will is not automatically invalid here. A contest on this ground argues that a formality was missed: only one witness signed, the witnesses were not present together, or a typed document was never properly witnessed and does not qualify as holographic.

5. Revocation

A will can also be attacked as no longer operative because the testator revoked it. California allows revocation by a later will or codicil that revokes the earlier one expressly or by inconsistency, and by a physical act such as burning, tearing, canceling, or destroying the document with intent to revoke. (Source: Cal. Prob. Code sections 6120-6124.) If a valid later will exists, the earlier document should not govern. Divorce is a related trigger: a California dissolution generally revokes gifts and appointments to the former spouse unless the will says otherwise.

Care Custodians and Drafters: A California Presumption

California has an unusual protection worth knowing. A gift in a will to certain people is presumed to be the product of fraud or undue influence and is treated as void unless the presumption is rebutted. These disqualified transferees include the person who drafted the document, a care custodian of a dependent adult who is the subject of the gift, and people closely connected to them. (Source: Cal. Prob. Code sections 21380-21392.) The law carves out exceptions, for example gifts to a spouse, domestic partner, or close relative, and gifts reviewed by an independent attorney who counsels the testator and signs a certificate. If a caregiver or the drafting attorney is a major beneficiary, this presumption can be a powerful part of a contest, so raise it with a California probate litigator.

Where and When You File

A California will contest is filed in the Superior Court, probate division, for the county where the decedent lived at death. The clerk of that court is where the original will is lodged, and where the petition to administer the estate is filed, so a contest travels with the probate case in that county.

Timing matters, and there are two paths. You can object to a will before it is admitted by filing an objection or a competing petition in response to the petition for probate. You can also act after a will is admitted. California sets a limited window to petition to revoke the probate of a will after it has been admitted, commonly measured as 120 days from the order admitting the will (a shorter period can apply to a person who was actually served with notice). (Source: Cal. Prob. Code sections 8250-8270.) Because the exact deadline and how it is measured depend on notice and the posture of the case, confirm the current deadline for your situation before you rely on any date. Do not wait. Building a contest takes time to gather records, locate witnesses, and retain an expert, and once the deadline passes the right to contest is generally lost for good.

No-Contest (In Terrorem) Clauses

Some wills include a no-contest clause, also called an in terrorem clause, that tries to disinherit any beneficiary who challenges the will. A typical version reads: if any beneficiary contests this will, that person's share is forfeited. The purpose is to scare beneficiaries out of litigating.

California limits how far these clauses reach. A no-contest clause is enforceable only against a direct contest (a challenge on grounds such as forgery, lack of capacity, undue influence, fraud, duress, revocation, or improper execution) that is brought without probable cause. (Source: Cal. Prob. Code sections 21310-21315.) Probable cause means a reasonable person, knowing the facts available when the contest was filed, would think the challenge had a reasonable likelihood of success. So a beneficiary with a genuine, well-supported ground can generally contest a California will without automatically forfeiting their gift, while a weak or speculative challenge can trigger forfeiture. The stakes are real, so have the clause and your evidence reviewed by a licensed California attorney before you file.

The Process, Step by Step

  1. Consult a probate litigator. Will contests are litigation, not routine estate paperwork. Find a California attorney who handles contested probate, and have them assess standing, grounds, and the deadline first.
  2. File your challenge. Either object before the will is admitted, or petition to revoke probate within the applicable window after admission, stating the grounds and naming the personal representative and beneficiaries.
  3. Discovery. Both sides exchange evidence: depositions of the drafting attorney, the attesting witnesses, caregivers, and family; subpoenas for medical and financial records; and expert reports on capacity or handwriting.
  4. Mediation and settlement. Many contests settle. A negotiated redistribution often costs far less than a trial and lets the family keep some control over the result.
  5. Trial. If the case does not settle, it goes to trial in the probate department. The contestant presents the challenge and must overcome the presumption that the will is valid.

What a Contest Costs and Whether It Is Worth It

Will contests are expensive and slow. Even a fairly clean case can take a year or more and run well into five figures in attorney fees, plus costs for experts, depositions, and records, and relatives often end up testifying under oath about a loved one's mental state and private affairs. For estate expenses generally, see the California probate costs guide, and for how a contest stretches the calendar, the California probate timeline guide. Before filing, weigh a few questions honestly:

  • Do you have standing? Would you actually inherit more if the will were set aside?
  • Do you have a real ground? Is there evidence of incapacity, undue influence, fraud, forgery, duress, or a signing defect, not just disappointment?
  • Is there a no-contest clause, and do you have probable cause for a direct contest?
  • Is the likely recovery worth the cost and the family strain, and could a settlement or mediation resolve it faster and for less?

If the answers point to a legitimate claim, move quickly. The window after a will is admitted is unforgiving, and the evidence is easiest to gather early.
