- The Burden: If you prove a “confidential relationship” and “active participation,” the burden of proof shifts to the wrongdoer to prove they didn’t use undue influence.

Proving Undue Influence in California Trust Contests: The Definitive Litigation Guide
The Presumption: How to Shift the Burden of Proof
Quick Answer: In California, undue influence is proven by showing the victim’s vulnerability, the influencer’s apparent authority, their tactics (isolation/haste), and the inequity of the result. UnderProbate Code § 8252, the contestant usually bears the burden, but a “presumption of undue influence” can shift this burden to the defendant if a confidential relationship and active procurement are proven.
At Leeran S. Barzilai, A Prof. Law Corp., we don’t wait for the defense to explain themselves. We aggressively seek to trigger the legal presumption of undue influence. To do this, we must prove three elements:
- Confidential Relationship: The influencer was a trustee, attorney, child, or caregiver.
- Active Participation: The influencer found the lawyer, drove the decedent to the office, or sat in on the signing.
- Undue Profit: The influencer received a significantly larger share than they would have naturally.
Strategic Note: Once these three elements are met, the law presumes the trust is invalid. The person who took the money must then prove “by clear and convincing evidence” that they did not exert pressure. This shift is the “holy grail” of trust litigation.
The 120-Day Clock: Calculating Your Deadline
Quick Answer: Once a trustee serves a “Notification by Trustee” pursuant toProbate Code § 16061.7, you have exactly 120 days from the date of service to file a petition in the Superior Court. Failure to meet this deadline typically bars your claim forever.
The Statute of Limitations Timeline
| Milestone | Timeline | Statutory Authority |
| Trust Becomes Irrevocable | Upon death of the Settlor | Probate Code § 16061.7 |
| Notice Served | Within 60 days of death | Probate Code § 16061.7 |
| Statute of Limitations | 120 Days from service | Probate Code § 16061.8 |
| Summons Issued | Upon filing of Contest | CCP § 412.20 |
Example Scenario: If a Trustee mails the notice on June 1st, your petition must be filed by September 29th. At our firm, we use a “double-audit” system for deadlines. We calculate the 120-day window and a secondary 60-day internal “evidence-gathering” deadline to ensure we have the medical records needed to support the filing.
Legal Deserts in California: How We Bridge the Gap Statewide
