Trustee Accounting: Definition and How It Works in California

By Eric Ridley, attorney, Ridley Law. Updated September 2026.

A trustee accounting is the periodic financial report a trustee must give beneficiaries, listing income received, disbursements made, and the assets remaining on hand.

How it works in California

Prob. Code, §§ 16062 and 16061 set the baseline: a trustee generally must account at least once a year, when the trust terminates, and when a trustee changes. California’s trustee accounting requirements spell out what the report has to include.

A proper accounting shows the trust’s assets at the start of the period, every receipt and disbursement during it, and the assets remaining at the end, in enough detail for a beneficiary to check the trustee’s work. Category totals alone don’t do that, and in 2026 a Virginia appeals court rejected a trustee’s reports built that way.

A trust document or a written waiver from all beneficiaries can modify or waive some accounting requirements, but a court can still order an accounting on a showing that it’s reasonably likely a material breach of the trust has occurred (Prob. Code, § 16064).

Why it matters

For example, a trustee who keeps loose notes instead of a formal accounting has a hard time defending their work later if a beneficiary questions a distribution, even when nothing improper actually happened.

Common mistakes

Trustees often mix personal and trust funds, which makes an accurate accounting nearly impossible to reconstruct. Others wait years to prepare the first accounting, well past the annual deadline the statute sets.
