Successor Trustee Duties: What the Next Trustee Actually Has to Do

When a California revocable living trust is set up, the trustor names a successor trustee — the person who will step in as trustee when the trustor dies, becomes incapacitated, or otherwise ceases to serve. The successor is usually a family member, sometimes a trusted friend or professional.

The successor trustee designation is often made with little discussion of what the role actually involves. This post is a short overview, written both for the people currently serving as successor trustees of California family trusts and for the people who might one day be asked to serve.

The basic legal framework

A California trustee's duties are governed primarily by Probate Code §§ 16000–16100. The core duties include:

• Duty to administer the trust according to its terms. The trust document is the principal source of authority and the principal source of constraint. The trustee's job is to do what the document says.
• Duty of loyalty. To act in the interest of the beneficiaries, not in the trustee's own interest. Self-dealing is disfavored and often categorically prohibited.
• Duty of care. To act with the care, skill, prudence, and diligence that a reasonably prudent person managing similar assets would use.
• Duty of impartiality. Where the trust has multiple beneficiaries (current and remainder), the trustee must act impartially among them.
• Duty to keep beneficiaries reasonably informed. Beneficiaries are generally entitled to information about the administration; specific accounting and notice obligations apply at defined milestones.
• Duty to account. Periodic accounting to beneficiaries is required, with specific content and frequency requirements.

These duties are abstract on paper. In practice, the trustee's day-to-day work is concrete and often surprisingly specific.

What a successor trustee actually does after stepping in

When a successor trustee steps in following the trustor's death, the typical workstream looks roughly like this:

Immediate (first 30 days).

• Notify named beneficiaries that they are entitled to receive notice under Probate Code § 16061.7 — the specific 60-day notice that triggers the running of the 120-day period during which beneficiaries can contest the trust
• Obtain certified death certificates (multiple copies; institutions request originals)
• Locate and inventory trust assets, including real property, accounts, business interests, and personal property
• Notify financial institutions of the trustor's death and the trustee's authority — typically by providing a "certification of trust" and the death certificate
• Secure any vacant real property and arrange for ongoing maintenance, insurance, and utility costs

First 90 days.

• Marshal trust assets — gather them under trustee control, retitling where appropriate
• Pay the trustor's final bills and the costs of trust administration as they come in
• Identify creditors and any potential claims
• Begin tax-related work — obtaining the trust's federal Tax ID (EIN), preparing or arranging for the trustor's final personal income-tax return, and considering the trust's own income-tax filings
• Communicate with beneficiaries about timeline expectations

Ongoing through distribution.

• Manage and invest trust assets prudently while administration continues
• Respond to beneficiary requests for information
• Address any claims by creditors, family members, or other parties
• Coordinate with attorneys and tax professionals as needed
• File accountings and reports as required by the trust and by statute

Final distribution.

• Distribute trust assets according to the trust's terms — outright distributions where called for, transfers into continuing trusts where called for
• Obtain receipts and releases from beneficiaries
• File final tax returns and close the trust's tax accounts
• Document the administration with a final accounting and close out

Depending on the size and complexity of the trust, this work can take anywhere from several months to several years. Trusts with real property, business interests, or contested provisions typically take longer.

What the trustee is paid

California trustees are entitled to "reasonable compensation" for their services unless the trust provides otherwise. For an individual family-member trustee, compensation is sometimes waived — the trustee serves as a family member rather than as a paid professional. For a non-family trustee or where the work is substantial, compensation is appropriate and should be agreed in advance.

The trustee is also entitled to reimbursement of reasonable expenses — accountant fees, attorney fees, real-estate-management costs, and similar — which are paid from trust assets rather than from the trustee's pocket.

Where successor trustees most often get into trouble

Three patterns the firm sees:

1. Acting before the legal authority is clear. A trustee should not be writing checks or selling assets before they have the documentation that establishes their authority — typically the certification of trust, the death certificate, and proof of identity. Acting without that documentation produces problems with banks, title companies, and tax authorities.

2. Treating the trust as their own. Even when the trustee is also a beneficiary (a common situation in family trusts), the duties of loyalty and impartiality apply. Self-dealing transactions, distributions to themselves before satisfying creditors, and similar actions can produce personal liability for the trustee.

3. Not communicating with beneficiaries. California's beneficiary-notice and accounting requirements are not optional. Beneficiaries who feel they are being kept in the dark are far more likely to file petitions with the probate court asking for information, accounting, or removal of the trustee.

What helps a trustee do the job well

Three practical steps:

Read the trust carefully. The document is the source of authority. Whatever it says about distributions, powers, and limitations is binding. A trustee who has not read the trust is operating on faith.

Get professional help where appropriate. Most successor trustees benefit from working with an attorney for the legal-procedural work, an accountant or CPA for the tax work, and sometimes a real-estate professional for property-related matters. The cost of these services is paid from trust assets, not from the trustee's pocket. Trying to do everything alone is usually a false economy.

Document everything. Every decision, every transaction, every communication with beneficiaries should be documented contemporaneously. The accounting at the end of the administration is built from these records, not reconstructed from memory.

When to call

For someone who has been named as a successor trustee and is now stepping in — or expects to step in soon — a consultation with counsel familiar with California trust administration is the right starting point. The firm can review the trust, walk through the workstream, and identify the specific issues that warrant early attention.

For someone who is currently serving and has questions about a specific issue — a beneficiary dispute, a complicated asset, a tax question — the firm is happy to consult on a discrete issue without taking over the full administration.
