Losing someone is hard. Challenging their will adds legal risk and strict timelines you should understand before you act.
Who can challenge a will
You need standing as an “interested person.” According to California Probate Code §48, this includes anyone with a financial interest in the estate who may be affected by the will’s validity. That can mean beneficiaries named in a current or prior will, heirs who would inherit if no will existed or certain creditors.
When to act
Timing controls your options. You may object before the court admits the will to probate. Once admitted, you typically have 120 days to file a contest. Missing that deadline may bar your claim entirely, even if you have valid grounds. Courts rarely extend this window except in rare cases involving fraud or lack of notice.
How the process works
A will contest follows formal probate rules and evidence standards. Here’s how the process generally unfolds:
- Confirm standing: Make sure you qualify as an interested person.
- Identify grounds: Determine if the issue involves capacity, undue influence, fraud or improper execution.
- File in probate court: Submit a verified petition stating your reasons for contesting.
- Serve notice: Notify all beneficiaries, heirs and the estate’s representative.
- Discovery: Collect and exchange medical, financial and witness evidence.
- Resolution: Attempt settlement or mediation. If unresolved, the case proceeds to trial.
These steps can clarify whether the will reflects the testator’s intent or requires judicial review.
Common grounds to raise
You may challenge a will based on several recognized legal theories. Here’s what you can consider:
- Lack of testamentary capacity: The testator didn’t understand their assets or heirs due to illness or cognitive decline.
- Undue influence: Someone pressured or manipulated the testator to alter the will.
- Fraud or forgery: The will was falsified or signed under deception.
- Improper execution: The will wasn’t properly signed or witnessed.
- Existence of a newer will: A later valid will may override the earlier one.
Each ground demands specific proof. Medical evidence, handwriting analysis, and credible witness statements are often central to the case.
What you can do next
Challenging a will is complex, emotional and time-sensitive. A probate attorney can assess your standing, verify deadlines and evaluate your evidence before you invest in litigation. Understanding California’s procedures and standards early can save time and reduce conflict.
