The successor trustee in California: what the job is, and how to appoint a professional one.
If a parent or spouse set up a living trust and named you to take over when they could no longer manage it, you are the successor trustee — and you may have just discovered the title comes with a real job and real legal duties. This page explains what a successor trustee does in California, the deadlines that matter, and when it makes sense to hand the role to a professional instead.
What a successor trustee is.
A living trust always has a trustee. While the person who created the trust — the settlor — is alive and well, they are usually their own trustee, managing their own assets exactly as before. The trust names a successor trustee to step in when the settlor can no longer serve: most often at death, sometimes earlier if the settlor becomes incapacitated and the trust says so.
When that moment comes, the successor trustee takes legal control of everything the trust owns and becomes responsible for administering it — following the instructions in the trust document and the rules in the California Probate Code. Unlike an executor, a successor trustee usually does this without ongoing court supervision, which is one of the main reasons people choose a living trust. That privacy and speed are real advantages. They also mean no judge is checking the trustee's work along the way — so the duties below are not optional, and the beneficiaries are the ones holding the trustee accountable.
The duties California imposes.
A successor trustee is a fiduciary, which is the law's word for someone who must put another person's interests ahead of their own. In California that translates into a specific set of duties, each with a section in the Probate Code:
- Follow the trust, and the law. Administer the trust according to its terms (Probate Code section 16000), and according to California law where the trust is silent.
- Loyalty. Act solely in the interest of the beneficiaries (section 16002) — no self-dealing, no favoring one beneficiary over another, no using trust assets for the trustee's own benefit.
- Invest prudently. Manage trust investments under the prudent investor standard (section 16047) and diversify holdings (section 16048). Leaving everything in a single stock, or large sums sitting idle, can itself be a breach.
- Inform and account. Keep the beneficiaries reasonably informed and provide accountings (sections 16060 through 16063). A formal accounting is generally due once a year, when the trust ends, and whenever the trustee changes (section 16062). Many trusts waive the routine accounting — but a beneficiary can demand one in writing regardless (section 16061).
These are enforceable, not aspirational. A trustee who breaches them can be held personally liable for the loss and removed by the court under section 15642.
The 60-day notice — the deadline that turns a quiet trust into a lawsuit.
When a revocable living trust becomes irrevocable — which usually happens the day the settlor dies — Probate Code section 16061.7 gives the successor trustee 60 days to send a written notice to every beneficiary and every heir of the deceased settlor. The clock runs from the death; if the trusteeship was vacant when the settlor died, it runs from the day the new trustee accepts the role.
Two parts of this trip people up constantly. First, the notice goes to heirs even if they were disinherited — a child the trust deliberately left out is still an heir at law and still gets the notice. Skipping them is the most common mistake. Second, the notice starts a 120-day clock for anyone to contest the trust. Send the notice correctly and that window closes in four months. Send it late, or incomplete, or not at all, and the window can stay open for years — which is how an estate that should have settled quietly becomes a contested case. The notice has to include specific contents the statute spells out, including a warning in exact statutory wording about that 120-day deadline.
None of this is hard for someone who does it routinely. It is very easy to get wrong for someone doing it once, while grieving.
The first year, in order.
Most of the work falls in the first twelve months, and the order matters:
- Accept the role — or decline it. Being named is not the same as serving. A named successor can decline under Probate Code section 15601, and the alternate (or a court-appointed substitute) steps in. Acceptance requires an affirmative act under section 15600 — typically signing an Acceptance of Trusteeship and a Certification of Trust the banks will ask for.
- Secure and inventory the assets. Locate the original trust document, secure the home and personal property, identify the bank, investment, and real-property holdings, and establish date-of-death values.
- Send the section 16061.7 notice within the 60-day window, with proof of delivery.
- Handle debts, taxes, and claims. Pay the final expenses, file the final income tax returns, and address any creditor claims before distributing.
- Account, then distribute. Prepare the accounting the beneficiaries are entitled to, then distribute the trust assets the way the document directs — outright, in continuing sub-trusts, or in whatever structure the settlor chose.
When a professional successor trustee makes sense.
Plenty of people serve as successor trustee for a parent or spouse and do it well. A professional fiduciary tends to be the better choice in a few recognizable situations: when the named successor has died, moved, or simply does not want the job; when the beneficiaries are in conflict and a neutral party is needed so the trustee is not also a combatant; when the trust holds something complicated — a business, rental property, a special-needs beneficiary, out-of-state assets; or when the person named is grieving and has no appetite for a year of deadlines and accounting.
A California professional fiduciary is state-licensed, bonded, and accountable for every decision and every dollar, with a fee schedule disclosed in writing before any work begins. A trustee is entitled to reasonable compensation under Probate Code section 15681, paid from the trust. You can also name a professional in advance — as the successor or alternate in a trust you are setting up now — so the people you love are not the ones running the trust the day you cannot.

Common questions.
What does a successor trustee actually do?
A successor trustee takes over a living trust when the person who set it up can no longer serve — usually because they have died, sometimes because they have become incapacitated. From that point the successor steps into a job with real legal duties: gather and protect the trust assets, send the notices California requires, pay the final bills and taxes, keep careful records, and distribute what is left to the beneficiaries the way the trust document says. It is an administrative and financial job, governed by the trust terms and the California Probate Code, and the person doing it answers to the beneficiaries for every decision.
Is a successor trustee the same as an executor?
No, though the jobs rhyme. An executor is named in a will and is appointed by, and reports to, the probate court. A successor trustee is named in a trust and ordinarily acts without ongoing court supervision — which is one of the main reasons people set up a living trust in the first place. Many estates have both: a trust holding most assets, with a "pour-over" will and an executor catching anything left outside it. We cover that comparison separately, but the short version is that the trustee runs the trust and the executor runs the probate.
How soon does a successor trustee have to notify the beneficiaries?
When a revocable living trust becomes irrevocable — which usually happens the day the person who created it dies — the successor trustee has 60 days to send a written notice under Probate Code section 16061.7 to every beneficiary and every heir of the deceased settlor. The clock runs from the death, or, if the trusteeship was vacant, from the day the new trustee takes over. This notice is the single most important early deadline, and missing it has real consequences (see below).
Does a successor trustee get paid?
Yes. A trustee is entitled to reasonable compensation for the work, even when the trust document does not state an amount — Probate Code section 15681 allows reasonable compensation when the instrument is silent. A family member who serves often waives the fee; a professional fiduciary charges for the time, discloses the rate in writing before the work begins, and the fee is paid from the trust. What is reasonable depends on the size and complexity of the trust and the actual work involved.
Can a successor trustee be held personally responsible if something goes wrong?
Yes, and this is why the role is heavier than it looks. A trustee who breaches their duties — mismanages assets, fails to account, favors one beneficiary over another, misses the required notices — can be held personally liable for the resulting loss to the trust and can be removed by the court under Probate Code section 15642. That exposure is one of the reasons families ask a licensed, bonded professional to take the role: the accountability is built in, and the work is done by someone who does it for a living.
