Few legal disputes are as personal as a fight over a loved one’s estate. A sibling discovers that their father’s trust was amended months before his death, leaving most of his Noe Valley home to a new spouse. A daughter in Elk Grove learns that her mother’s caregiver is now the primary beneficiary of a will signed during a hospital stay. In both cities, the questions are similar: Was this really what my parent wanted, and what can I do about it?
This article explains how will and trust contests work in California, with particular attention to the issues families face in San Francisco and the Sacramento region, including who can sue, what must be proven, and the deadlines that control everything.
Key Takeaways
- Only “interested persons,” typically heirs and beneficiaries, can contest a will or trust.
- Common grounds include lack of capacity, undue influence, fraud, and improper execution.
- California presumes undue influence in certain transfers to drafters, caregivers, and related parties.
- Deadlines are short, often 120 days, and missing them can end a claim permanently.
- No-contest clauses are enforceable in limited situations, and probable cause can protect a challenger.
Who Can Bring a Contest?
California Probate Code section 48 defines an “interested person” broadly to include heirs, beneficiaries, and others with a property right or claim against the estate that may be affected by the proceeding. In practical terms, contests are usually brought by children, spouses, or beneficiaries named in an earlier version of the estate plan who would receive more if the challenged document were invalidated.
Standing matters. A person who would receive nothing even if the contest succeeded generally cannot bring it.
Grounds for Challenging a Will or Trust
Lack of testamentary capacity
Under Probate Code section 6100.5, a person lacks capacity to make a will if they could not understand the nature of the act, the nature and situation of their property, or their relationships with family members whose interests are affected. Medical records, physician testimony, and witness accounts are central evidence. Diagnoses alone are not decisive. A person with early dementia may still have capacity on a particular day.
Undue influence
Undue influence occurs when someone uses excessive persuasion to overcome a person’s free will. California’s definition, referenced in Probate Code section 86, looks at the vulnerability of the person, the influencer’s apparent authority, the tactics used, and the fairness of the result. Evidence often includes isolation from family, control over finances, and sudden changes to longstanding plans.
Statutory presumption
Probate Code section 21380 presumes that certain transfers are the product of fraud or undue influence, including transfers to the person who drafted the instrument, to a care custodian of a dependent adult in some circumstances, and to certain related individuals. The beneficiary must then prove by clear and convincing evidence that the transfer was not the product of fraud or undue influence. This presumption is a powerful tool in caregiver cases.
Fraud and forgery
Fraud occurs when a person is deceived into signing a document or into making particular gifts. Forgery cases often involve handwriting experts and close examination of signatures.
Improper execution
A formal California will generally must be signed by the testator and two witnesses under Probate Code section 6110. Handwritten holographic wills are valid if the signature and material provisions are in the testator’s handwriting under Probate Code section 6111. Errors in execution can make a document vulnerable.
Deadlines That Cannot Be Missed
Timing is often the most important factor in a contest.
- Wills: After a will is admitted to probate, Probate Code section 8270 generally allows 120 days to file a petition to revoke the probate.
- Trusts: When a trust becomes irrevocable, the trustee must send a notice under Probate Code section 16061.7. Under section 16061.8, a contest must generally be filed within 120 days after service of that notice, or 60 days after a copy of the trust terms is delivered if requested during the 120-day period, whichever is later.
Once these periods expire, challenges are usually barred. Anyone who receives a trustee notice should treat it as a starting gun.
No-Contest Clauses
Many estate plans include a no-contest clause that disinherits a beneficiary who challenges the document. Under Probate Code section 21311, these clauses are enforced against a direct contest only if the contest was brought without probable cause, along with certain property ownership and creditor claims if the clause expressly covers them. Probable cause exists when the facts known to the contestant would cause a reasonable person to believe there is a reasonable likelihood the requested relief will be granted after further investigation. An experienced attorney can help evaluate this risk before filing.
San Francisco Considerations
Estate disputes in San Francisco often involve extraordinarily valuable real estate, from Victorian homes to condominiums in South Beach, along with significant investment portfolios and tech equity. Blended families and late-in-life marriages are common sources of conflict. Probate matters are heard in San Francisco Superior Court at the Civic Center Courthouse on McAllister Street. Families facing these disputes frequently turn to probate attorneys in San Francisco who understand both the local court and the valuation issues that come with high-cost property.
Sacramento Region Considerations
The Sacramento area has a large population of retirees in communities such as Roseville, Folsom, Carmichael, and Elk Grove, and many of them rely on caregivers or adult children for daily support. That creates fertile ground for caregiver and undue influence disputes, as well as financial elder abuse claims. Under Welfare and Institutions Code section 15657.5, a successful financial elder abuse claim can carry an award of attorney fees and costs. A skilled Sacramento probate attorney can assess whether elder abuse remedies should be pursued alongside a traditional contest.
Building a Strong Case
Successful contests share some features:
- Early action. Calendar deadlines immediately and gather documents before they disappear.
- Medical evidence. Obtain records from physicians, hospitals, and care facilities around the date the document was signed.
- Witness accounts. Identify friends, neighbors, and professionals who saw the decedent regularly.
- Prior estate plans. Earlier wills and trusts help show what the decedent wanted before the alleged influence.
- Financial records. Bank statements can reveal unusual transfers or control by the beneficiary.
Frequently Asked Questions
How long do I have to contest a trust in California?
Generally 120 days after the trustee’s notice is served, or 60 days after you receive a requested copy of the trust if that is later.
What evidence proves undue influence?
Typical evidence includes isolation of the decedent, control over finances, involvement in drafting the document, sudden changes to long-held plans, and a result that unduly benefits the influencer.
Will I lose my inheritance if I contest and lose?
Possibly, if the estate plan contains a no-contest clause and the court finds you lacked probable cause. With probable cause, the clause generally cannot be enforced against a direct contest.
Can a caregiver inherit under California law?
Yes, but transfers to certain care custodians of dependent adults may be presumed invalid unless the caregiver proves the gift was not the result of fraud or undue influence, or another exception applies.
Honoring What a Loved One Truly Wanted
Will and trust contests are difficult, but they exist to protect people’s genuine wishes. Families in San Francisco and Sacramento who act quickly, gather evidence carefully, and understand the legal standards are best positioned to determine whether a challenged document reflects their loved one’s real intentions.
