Probate Code Section 17200: The Petition That Starts Most Trust Disputes
Probate Code section 17200 lets a trustee or a beneficiary petition the probate court about the internal affairs of a trust. It is the single door most California trust disputes go through, and the relief you ask for inside it — an accounting, instructions, removal, or redress for a breach — shapes everything that follows.
For a consultation, keep the petition or notice, trust documents and hearing date available. Ask the firm which issue needs review before sending confidential documents.
Almost every California trust dispute that reaches a courtroom arrives as a petition under section 17200. People usually meet the number before they understand it — in a letter from a lawyer, or in a filing served on them — and the number tells them almost nothing about what is actually being asked for. That is the useful part to understand.
What the section actually does
Probate Code section 17200 allows a trustee or a beneficiary of a trust to petition the probate court concerning the internal affairs of the trust, or to determine the existence of the trust. “Internal affairs” is broad by design: the statute goes on to list purposes that range from settling a trustee’s accounts and instructing a trustee, to determining who the beneficiaries are and whether a particular provision is valid, to fixing trustee compensation, appointing or removing a trustee, and compelling redress of a breach of trust. One petition may carry several of these at once, and often does — a petition to compel an accounting and remove a trustee is a single filing, not two. The section is therefore less a cause of action than a doorway, and what matters is which relief a petitioner walks through it to ask for.

Everything section 17200(b) lists
Subdivision (b) lists proceedings concerning the internal affairs of a trust, and says the list is not exhaustive. Grouped by what they are for:
| Group | 17200(b) paragraphs |
|---|---|
| What the trust means and who takes | (1) construing the instrument; (2) whether an immunity, power, privilege, duty or right exists; (3) the validity of a trust provision; (4) ascertaining beneficiaries and who receives property on termination |
| Supervising the trustee | (5) settling accounts and passing on the trustee’s acts, including discretionary powers; (6) instructing the trustee; (8) granting powers; (9) fixing or reviewing trustee compensation |
| Forcing the trustee to act | (7) compelling a copy of the trust terms, information under section 16061, or an account, subject to the waiting periods below |
| Who serves | (10) appointing or removing a trustee; (11) accepting a resignation |
| Breach | (12) compelling redress of a breach of trust by any available remedy |
| Changing the trust | (13) approving or directing modification or termination; (14) combining or dividing trusts; (15) conforming a trust to qualify for the federal charitable estate tax deduction |
| Moving the trust | (16) transfer to or from another jurisdiction; (17) moving a testamentary trust between counties; (18) removing a testamentary trust from continuing court jurisdiction |
| Specialized matters | (19) reforming an organization’s governing instrument under section 16105; (20) the trust’s liability for a deceased settlor’s debts; (21) petitions under section 15687 on legal-services compensation; (22) and (23) practice administrators for a deceased or disabled State Bar member |
Two limits in the section decide whether a petition is premature. The first is in paragraph (7): a beneficiary can compel information requested under section 16061 only if the trustee has not provided it within 60 days after a reasonable written request and nothing was received in the six months before the request, and can compel an account, subject to section 16064, only if none was provided within 60 days of a written request and none was made in the preceding six months. The second is the opening words, “except as provided in Section 15800”: while a trust is revocable and the person holding the power to revoke is competent, the rights the code gives beneficiaries belong to that person instead. A petition built on a beneficiary’s rights generally has to wait until the trust has become irrevocable or the settlor is incapacitated.

The relief a 17200 petition usually asks for
Each of these is a different case with different evidence, a different likely outcome and a different cost. The page linked beside each one covers it properly.
| What you are asking for | When it is the right ask | Covered on |
|---|---|---|
| Compel an accounting | The trustee has not accounted, or the account you received does not add up | Trust accounting |
| Compel a distribution | The trust directs a distribution and the trustee will not make it | Trustee refuses to distribute |
| Remove or replace the trustee | Breach, hostility, unfitness, or a failure to act that is holding the trust up | Trustee removal |
| Redress a breach of trust | The trust lost value, or the trustee gained, because of what the trustee did | Trustee surcharge |
| Fix or reduce trustee compensation | The trustee is paying themselves an amount the work does not support | Trustee compensation |
| Instruct the trustee | The terms are genuinely unclear and the trustee needs cover to act | Living trust disputes |
| Resolve a deadlock between co-trustees | Two trustees who must act together will not | Co-trustee disputes |
Filing a 17200 petition: county, notice and orders
Three procedural sections govern the filing. Section 17005 fixes the county: for a living trust, the county where the trust's principal place of administration is located; for a testamentary trust, either that county or the county where the decedent's estate is administered. Section 17203 fixes notice: at least 30 days before the hearing, the petitioner must deliver notice to all trustees and all beneficiaries, and must serve notice and a copy of the petition on anyone else whose right, title or interest would be affected, a period the court may not shorten for those persons. Section 17206 fixes the court's reach: it may make any orders and take any other action necessary or proper to dispose of the matters the petition presents, including appointing a temporary trustee to administer the trust in whole or in part while the dispute is decided.

Remedies for breach, and the three-year limit
When the petition alleges a breach, section 16420 supplies the menu of relief a beneficiary or cotrustee can request: compelling the trustee to perform, enjoining a threatened breach, compelling redress by payment of money, appointing a receiver or temporary trustee, removing the trustee, setting aside the trustee's acts, reducing or denying the trustee's compensation, imposing an equitable lien or constructive trust, and tracing and recovering property wrongfully disposed of, several of them subject to the protection section 18100 gives good-faith third parties. Those claims do not stay open indefinitely. Under section 16460, a breach claim is generally barred unless brought within three years after the beneficiary receives a written account or report that adequately discloses it, or, if nothing adequately disclosed it, within three years after the beneficiary discovered or reasonably should have discovered the subject of the claim.

The petition does not determine the deadline
Section 17200 can be the procedural vehicle for determining the existence of a trust or the validity of a trust provision. A claim that an amendment resulted from undue influence or lack of capacity is still a trust contest, with deadlines determined by the substantive claim and applicable notice. Calling it a section 17200 petition does not extend a contest deadline.
The trust contest deadline calculator estimates the section 16061.8 period from qualifying notice and trust-delivery dates. It does not decide which limitation period applies to a claim.
Where this sits in the wider process
A 17200 petition is the opening move, not the whole case. What follows it — the response, discovery, mediation, and occasionally trial — is set out in how a trust dispute actually runs. Most resolve well before a judge decides anything, and the relief asked for in the original petition tends to define the shape of the settlement.

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.
