Quick Answer
To contest a will in California you must have standing as an interested person, file within a short statutory window, and prove a recognized ground such as undue influence, lack of capacity, fraud, or improper execution. Losing can carry real consequences, including forfeiture of an inheritance under a no contest clause when the challenge was brought without probable cause.
Key Takeaways
- A beneficiary who receives proper notice of trust administration generally has 120 days to bring a trust contest.
- Once a will is admitted to probate, a petition to revoke probate generally must be filed within 120 days of that order.
- California limits enforcement of no contest clauses to direct contests brought without probable cause, plus narrow categories of other claims.
- California recognizes a presumption of undue influence where a person in a confidential relationship who actively participated in procuring the document receives an undue benefit.
- Testamentary capacity in California is a relatively low standard, and a diagnosis alone does not establish incapacity.
Who Can Contest
Only an interested person has standing. That generally means someone who would inherit if the challenged document were invalid, either under a prior will or trust or under California’s intestate succession rules. It also includes creditors of the estate in limited circumstances.
A neighbor who feels the distribution was unfair has no standing. A disinherited child usually does, because they would take a share under intestacy if the will fell.
The Grounds
Undue Influence
This is the most frequently asserted ground. California defines it as excessive persuasion that overcomes another person’s free will and results in inequity. Courts examine the vulnerability of the person who signed, the influencer’s apparent authority, the tactics used, and whether the outcome was equitable.
A presumption of undue influence arises where someone in a confidential relationship with the decedent actively participated in preparing the document and received an undue benefit from it. When that presumption applies, the burden shifts to the beneficiary to disprove it, which is a meaningful advantage for the contestant.
Typical fact patterns involve a late-in-life caregiver who isolates the person from family, arranges the meeting with the drafting attorney, and receives a substantially increased share in an amendment signed weeks before death.
Lack of Testamentary Capacity
California asks whether the person understood the nature of the act, understood generally the nature and extent of their property, and remembered their relatives and the people who would naturally be objects of their bounty.
The bar is lower than many contestants expect. A dementia diagnosis does not establish incapacity, because capacity is measured at the moment of signing and lucid intervals are recognized. Medical records, contemporaneous observations, and the drafting attorney’s notes carry substantial weight.
Fraud
Fraud in the inducement involves misrepresentations that caused the person to sign, such as false statements about a family member’s conduct. Fraud in the execution involves deceiving the person about the nature of the document itself.
Improper Execution
California requires a formal will to be in writing, signed by the person making it, and witnessed by two people present at the same time who understood the document was a will. A holographic will, one written entirely in the person’s own handwriting and signed, is valid without witnesses. Execution defects are among the cleanest grounds because they turn on documentary proof rather than intent.
Revocation and Later Documents
A will can be revoked by a later will, by a codicil, or by physical destruction with intent to revoke. Disputes often center on whether a later amendment was validly executed or whether an earlier document was properly revoked.
The Deadlines
Probate deadlines are unforgiving.
For a will, once the court admits it to probate, an interested person generally has 120 days from that order to petition to revoke probate. Someone who did not receive notice may have a longer window in narrow circumstances.
For a trust, the trustee’s notification under Probate Code section 16061.7 starts a 120-day clock. A beneficiary who wants to contest must file within that period or generally lose the right entirely.
These windows are short enough that anyone who receives a notice from a trustee should treat it as time-sensitive. Getting the document reviewed by a California probate attorney matters more here than in most other areas of civil practice, because the deadline is measured in weeks rather than years.
No Contest Clauses
Many California wills and trusts contain a clause stating that anyone who challenges the document forfeits their inheritance. California has substantially narrowed how these operate.
Under current law, a no contest clause is enforceable against a direct contest only when the contest was brought without probable cause. Probable cause exists if, at the time of filing, the facts known to the contestant would cause a reasonable person to believe a reasonable likelihood of success existed after further investigation.
The clause can also be enforced against a pleading challenging a transfer of property on the ground it was not the transferor’s, or against a creditor’s claim, but only if the instrument expressly provides for it.
The practical effect is that a contestant with genuine evidence of undue influence usually is not risking forfeiture. A contestant filing on suspicion alone is.
How the Process Runs
Will and trust contests proceed in the probate division and follow a litigation path resembling ordinary civil cases. The contestant files a petition, the proponent responds, and discovery follows.
Discovery in these cases tends to concentrate on a specific set of sources: medical records covering the period around execution, the drafting attorney’s file and notes, financial records showing transfers during the same window, caregiver records, and communications among family members.
Depositions of the drafting attorney and the witnesses to the signing are often decisive. So are the decedent’s own physicians.
Trials in probate matters are generally decided by a judge rather than a jury, though limited jury rights exist for certain claims. Many contests resolve through mediation, since the litigation costs come out of the same estate everyone is fighting over.
If You Lose
Three consequences follow an unsuccessful contest.
The document stands as written and distribution proceeds accordingly. If a no contest clause applies and the court finds no probable cause, the contestant may forfeit whatever they would otherwise have received. And the contestant bears their own attorney fees, which in a contested probate matter can be substantial.
A losing contestant may also face a fee award in narrow circumstances, though California does not generally shift fees in probate contests absent a statutory or contractual basis.
Appealing an Adverse Ruling
Probate orders are appealable, but appeal is not a second trial. An appellate court reviews for legal error and does not reweigh the evidence or reassess witness credibility. Factual findings supported by substantial evidence stand even if the appellate court might have decided differently.
The deadline is strict. A notice of appeal in California is generally due within 60 days of service of notice of entry of judgment, with an outer limit of 180 days. Anyone considering the step should look closely at the grounds for appealing a California court ruling before assuming an unfavorable outcome can be revisited.
Frequently Asked Questions
Can I contest a will before the person dies?
No. A will has no legal effect until death and can be changed at any time before then. Concerns about a living person’s vulnerability are addressed through other mechanisms, including conservatorship proceedings and elder abuse claims.
What if I was left out entirely?
California permits disinheritance of adult children. Being excluded is not itself a ground for contest. There are narrow exceptions for omitted spouses and children born or adopted after the document was executed, who may take a statutory share unless the omission was intentional.
How much does a will contest cost?
Costs depend on the discovery required. Cases turning on execution defects can be relatively contained. Undue influence cases requiring medical records review, multiple depositions, and consultants on capacity run considerably higher. Weighing the likely cost against the size of the disputed share is the first practical question.
Does a trust avoid all of this?
A trust avoids the probate administration process but not contests. Trusts can be challenged on the same grounds as wills, and the 120-day notification deadline applies. Trust contests are common and follow a similar evidentiary path.
What is the difference between a will contest and a claim against a trustee?
A contest challenges the validity of the document itself. A breach of trust claim accepts the document and alleges the trustee mismanaged assets, self-dealt, or failed to account. These claims have different deadlines and different remedies, and a beneficiary sometimes has both.
