What is a Successor Trustee in California? Duties, Authority, and First Steps

A successor trustee is the person (sometimes an institution) named in the trust to take over management and administration of the trust when the current trustee dies, becomes incapacitated, or resigns. Once the conditions for a successor trustee are met, the person named as successor trustee must decide whether to accept the job. Once you accept, you take on a fiduciary duty (which means a very high level of care and responsibility) to the trust beneficiaries to follow the instructions in the trust and California law, secure and protect the trust assets, and act in the best interests of the beneficiaries.

What Does "Successor Trustee" Mean?

The person who creates a trust is called the grantor or settlor. The person who manages the trust is called the trustee. With a revocable living trust, which is the foundational document for most California estate plans, the grantor is the initial trustee. For example, a husband and wife create a living trust and name themselves trustees.

The successor trustee is the one they've named in the trust to take over management of the trust if something happens to them: death, incapacity, or they want to hand over control to a more capable person - like the responsible child that lives nearby. And preferably they name a first choice, second choice,  and even third choice for successor trustee.

The main concept here is that the assets the grantor transfers to the trust - their home, investment accounts, bank accounts, business, etc.- are controlled by the terms of the trust. The trustee's job is to follow and execute the terms of the trust for those assets for the benefit of the trust beneficiaries. 

With a living trust where the grantors are alive, the beneficiaries are the grantors. If the grantors become incapacitated, the beneficiaries are still the grantors. But when the grantors die, the successor beneficiaries are the individuals or charities named in the trust. 

The successor trustee steps in to follow the trust terms (and California law) to administer the trust for the benefit of the incapacitated grantors, or, when the grantors die, for the benefit of the successor beneficiaries.

A Successor Trustee is Not the Same as an Executor or an Agent

Trustee, executor, and agent are all different roles assigned to people in an estate plan. Often the same person is given all the roles. But the roles are different. Trustee is the person in charge of the trust. Executor is the person in charge of the will. And the agent is the person in charge of the durable power of attorney, the health care directive, and HIPAA. 

What Are a California Successor Trustee's Main Duties?

The details can vary based on the specific terms of the trust, but the core duties are consistent.

1. Follow the trust

Read the complete trust and every amendment. Identify who is serving, who benefits, what expenses may be paid, whether assets must remain in trust, and what must be distributed. Do not rely on a summary, an old estate-planning binder tab, or what the family believes the document says.

2. Act for the beneficiaries—not for yourself

California Probate Code section 16002 requires the trustee to administer the trust solely in the beneficiaries’ interest. Section 16004 bars the trustee from using trust property for personal profit or entering transactions in which the trustee’s interest is adverse to a beneficiary.

In practical terms, do not borrow trust money, use trust property as your own, favor your side of the family, or buy an asset from the trust without first obtaining careful legal advice.

3. Treat beneficiaries impartially

Impartiality does not always mean identical treatment. It means respecting the different interests the trust creates without playing favorites. A current income beneficiary and a remainder beneficiary may have different interests. The trustee must consider both.

4. Take control of and preserve trust property

The trustee must take reasonable steps to secure and preserve trust property. That may mean protecting a vacant home, maintaining insurance, stopping unauthorized withdrawals, locating accounts, securing valuables, and making sure taxes and necessary expenses are addressed.

It does not mean immediately selling everything. The trust, the nature of the assets, tax consequences, market conditions, liquidity needs, and beneficiary rights all matter.

5. Keep beneficiaries reasonably informed

Silence creates suspicion. California Probate Code section 16060 requires a trustee to keep beneficiaries reasonably informed about the trust and its administration. That does not require responding instantly to every demand, but it does require accurate, timely, and evenhanded communication.

When a revocable trust becomes irrevocable at death, Probate Code section 16061.7 generally requires a formal notification to specified beneficiaries and heirs within 60 days. The notice has mandatory content and affects the time to contest the trust. It should not be improvised from an online sample.

6. Keep records and account

From the first day, keep trust money separate and document every receipt, expense, sale, transfer, and distribution. Probate Code section 16062 generally requires an accounting at least annually.

Good records are not merely an end-of-administration task. They are one of the trustee’s best protections if a beneficiary later questions a decision.

What Authority Does a Successor Trustee Have?

A properly acting successor trustee can generally exercise the powers granted by the trust and California law. Depending on the document and the assets, those powers may include collecting trust property, managing accounts, hiring professionals, paying proper expenses, selling or transferring assets, handling claims, filing tax returns, and making distributions.

But authority and discretion are not the same as personal freedom. Every power must be used for a proper trust purpose, consistently with the trust and the trustee’s fiduciary duties.

Before taking a major action, especially selling to a family member, making unequal preliminary distributions, changing investments, using trust property, or resolving a dispute, ask whether the trust permits it, whether the decision is fair to all affected beneficiaries, and whether the file will show why the decision was reasonable.

What Should a Successor Trustee Do First?

A newly acting successor trustee does not need to solve the entire administration in the first week. The immediate goal is to establish authority, prevent loss, and preserve options.

1. Locate the signed trust, all amendments, and related estate-planning documents.
2. Confirm the event that activates the succession clause and obtain the proof the trust requires - like incapacity or death of the grantor.
3. Decide whether to accept the role. If you do not want to serve, get advice before exercising trustee powers. You can opt not to serve.
4. Identify cotrustees and determine who must sign or act.
5. Secure homes, vehicles, financial accounts, mail, digital records, and other trust property.
6. Create an initial asset and liability list, distinguishing trust assets from individually owned and beneficiary-designated assets.
7. Calendar legal deadlines, including any required trustee notification.
8. Keep trust funds separate and begin a transaction record immediately.
9. Before selling, distributing, retitling, or borrowing against property, review the trust and obtain advice appropriate to the transaction.

Many successor trustees hire an attorney experienced in trust administration to guide them through the process. The job involves significant responsibilities, deadlines, and potential liability, and obtaining advice early can help prevent avoidable mistakes.

What if an Asset is Not in the Trust?

A trust controls property held in the trust. If a house, account, or other asset remains in the deceased owner’s individual name, the successor trustee cannot assume that the trust document alone gives authority over it.

The next step depends on the asset, how title is held, the beneficiary designation, the value involved, and the available evidence of the owner’s intent. The answer may involve a nonprobate transfer procedure, a court petition, or probate.

Can a Successor Trustee be Personally Liable?

Potentially, yes. A trustee who breaches the trust or fiduciary duties may face objections, removal,  or other remedies. Personal exposure is not automatic simply because a beneficiary is unhappy. The question is whether the trustee acted within the trust, fulfilled the applicable duties, and made and documented decisions with appropriate care.

The avoidable problems are familiar: mixing funds, making premature distributions, ignoring notice or tax issues, favoring one beneficiary, using trust property personally, failing to insure or secure assets,  and keeping poor records.

Do You Have to Serve?

No one should accept the role by reflex. The trust may name another successor, provide a method for filling the vacancy, or require a court appointment if no named person can serve. If the administration is contentious, technically difficult, or simply beyond the time you can give it, declining before you begin may be the responsible choice.

We've had cases where the successor trustee was unqualified to serve as trustee. But he took on the role anyway and months later realized he was over his head and resigned.

Get advice before acting if you are uncertain. Starting to exercise trustee powers and then trying to step away can make the transition harder.

The Practical Bottom Line

A successor trustee is not just the person who signs the final checks. The trustee takes legal responsibility for carrying out the grantor’s instructions, protecting property, communicating with beneficiaries, and documenting the administration.

Your first job is not to move quickly. It is to establish that you have authority, understand the document, secure the assets, and avoid decisions that cannot be undone.
