How a California Trust Dispute Actually Works
A California trust or estate dispute runs in stages: investigation, a petition to the probate court, discovery, mediation, and — rarely — trial. Most resolve at or before mediation. The first filing is usually a petition concerning the internal affairs of the trust under Probate Code section 17200.
The petition that starts it
Most California trust disputes begin with a petition under Probate Code section 17200, which allows a trustee or a beneficiary to petition the court concerning the internal affairs of the trust. The relief sought shapes everything that follows. A petition to compel an accounting rests on section 16062, which requires a trustee to account at least annually, at termination, and on a change of trustee, to each beneficiary to whom income or principal is currently distributable. A petition to remove rests on section 15642, which permits removal for breach of trust, unfitness, insolvency, excessive compensation, hostility impairing administration, failure to act, or other good cause. These are commonly filed together, and often alongside a surcharge claim seeking to hold the trustee personally responsible for losses caused to the trust. A contest of the instrument itself runs on its own, shorter clock.

The stages, and what actually happens in each
| Stage | What happens | Typical duration |
|---|---|---|
| 1. Investigation | Documents gathered, deadlines calculated, the instrument and its drafting history reviewed | Days to weeks |
| 2. Demand | A letter that often produces the accounting or disclosure without a filing | 2–6 weeks |
| 3. Petition | Filed in the probate department of the relevant county; first hearing set | 1–3 months to first hearing |
| 4. Discovery | Records subpoenaed, depositions taken — medical, banking, and the drafting attorney’s file | 4–12 months |
| 5. Mediation | A day with a neutral. Most matters end here | 1 day |
| 6. Trial | Heard by a probate judge, not a jury | Rare; 12–24 months in |
Durations are practical observations from California probate practice and vary substantially by county calendar and by how the other side engages. They are not commitments.
Why most cases end at mediation
Because by then both sides have seen the same records. The medical notes either show decline around the signing date or they do not; the bank statements either show the transfers or they do not. Litigation is expensive and public, and the estate pays for much of it either way. Once the evidence is on the table, the arguments usually narrow to a number.
That is also why the investigation stage matters more than it looks. Cases are largely won or lost by what gets preserved and obtained early.
What you will actually be asked to do
- Provide dates and documents. The notice, the instrument, anything you were sent.
- Sit for a deposition, if it gets that far. Usually a few hours, usually remote.
- Attend mediation. A full day, and the one part where showing up matters.
- Decide. Settlement is always yours to accept or refuse.

How contingency fees work in California
A contingency fee means the attorney is paid from what is recovered rather than by the hour, so a beneficiary who cannot fund litigation out of pocket can still bring a claim. California regulates these agreements closely. Under Business and Professions Code section 6147, the agreement must be in writing and the attorney must give the client a duplicate copy, signed by both, when the contract is made. It must state the agreed contingency rate; how disbursements and costs incurred in prosecuting or settling the claim will affect that fee; and to what extent the client could be required to pay for related matters. Unless the matter falls under section 6146, the agreement must also state that the fee is not set by law and is negotiable. These are not formalities: failure to comply with any provision of section 6147 makes the agreement voidable at the client’s option, leaving the attorney entitled only to a reasonable fee.

Not every matter suits a contingency arrangement, and the firm does not take every case on one. Whether yours qualifies depends on the facts, the likely recovery, and the assets actually available to satisfy a judgment. Ask when you call.
