California Trust Administration
Trust administration is what a successor trustee does after a settlor dies: accepting the office, notifying beneficiaries and heirs when required, gathering and valuing assets, paying proper debts and taxes, accounting, and distributing what the trust directs. It ordinarily proceeds without ongoing court supervision.

What administration is, and what it is not
A revocable living trust keeps an estate out of probate by making a private officer — the successor trustee — do the work a court-appointed representative would otherwise do under supervision. Nobody issues letters. No judge signs off on the inventory. Probate Code section 16000 supplies the authority and the constraint together: on acceptance, the trustee has a duty to administer the trust according to the trust instrument and, where the instrument is silent, according to the Trust Law. Two obligations run from the first day. Section 16060 requires the trustee to keep beneficiaries reasonably informed of the trust and its administration, which is a standing duty rather than an annual event. And section 16061.7 requires notification to be served on each beneficiary of the now-irrevocable trust and each heir of the deceased settlor. That notice is also the trustee’s own protection: service starts the 120-day period under section 16061.8 in which a contest must be brought, and until it is served, nobody’s clock runs.

The sequence, and roughly when each part happens
| Stage | What the trustee does | Typical timing |
|---|---|---|
| Accept the office | Locate the original trust and every amendment; read them before acting | Week 1 |
| Secure the assets | Change locks if needed, confirm insurance, stop automatic payments | Weeks 1–2 |
| Serve the notification | When section 16061.7 applies, on each beneficiary of the irrevocable trust or portion and each heir of the deceased settlor, subject to the statute’s limitations | Generally within 60 days of the triggering event |
| Obtain a taxpayer number | The trust is now a separate taxpayer; open an account in its name | Month 1 |
| Inventory and value | Date-of-death values for every asset, including a qualified appraisal where one is needed | Months 1–3 |
| Debts, expenses and taxes | Final personal income tax return, any trust return, creditors, property tax | Months 2–9 |
| Account to beneficiaries | The report the Trust Law requires, showing receipts, disbursements and property held | Before distribution |
| Distribute | Outright shares, or funding the sub-trusts the instrument creates | After the contest window closes |
These are planning ranges, not legal deadlines. The notification has a statutory service period when section 16061.7 applies; the rest depend on the instrument, assets, taxes, debts and any dispute.
The mistakes that turn administration into litigation
Four recurring errors can turn a private administration into litigation. Distributing before claims, taxes and a possible contest are addressed can expose the trustee if property later has to be recovered. Paying trust expenses from a personal account — or the reverse — can breach the duty to keep property separate and makes the accounting difficult to reconstruct. Going silent conflicts with the duty to keep beneficiaries reasonably informed. And using, renting, or buying trust property for the trustee’s own benefit raises the conflict and self-dealing rules even if the trustee believes the price is fair. None requires bad intent; all are easier to prevent than to unwind.
Trust administration or probate?
The two are not alternatives so much as two answers to what the decedent owned at death. Property titled in the name of the trust is administered under the trust. Property in the decedent’s own name is not, however clear the trust’s intentions were, and it needs probate administration or one of the statutory shortcuts — unless the asset was meant to be in the trust and never retitled, which is what a Heggstad petition exists to fix. Many estates run both processes at once. Whether probate is needed at all is the question to settle first.

When a beneficiary is on the other side of this
This page is written for the trustee. The same events look different from the receiving end, and those pages are written from there: what a beneficiary is entitled to, what the notification means when it arrives, and how long the contest window actually runs. A trustee reading those is doing the job properly — they are the questions the beneficiaries are about to ask.
