Successor Trustee Duties: A Step-by-Step Guide for California Families

Being named successor trustee is an honor — but it also comes with significant legal responsibility. If you’ve recently taken on this role after a loved one’s passing or incapacity, it’s normal to feel uncertain about where to start. California law imposes specific duties on trustees, and missteps can create personal liability. Here’s a practical, step-by-step overview to help you navigate the process with confidence.

Step 1: Locate and Review the Trust Document

Your first task is to obtain the original trust agreement and any amendments. Read it carefully — or better, have an attorney review it with you — to understand:

• Who the beneficiaries are and what they’re entitled to receive
• Your specific powers and any limitations
• Whether the trust requires an accounting or notice to beneficiaries

Step 2: Provide Formal Notice to Beneficiaries and Heirs

California Probate Code Section 16061.7 requires a successor trustee to send a formal notice to all beneficiaries and legal heirs within 60 days of the trust becoming irrevocable (typically upon the settlor’s death). This notice starts a 120-day window during which beneficiaries can contest the trust, so getting it right — and on time — is critical.

Step 3: Secure and Inventory Trust Assets

Next, identify, locate, and protect everything the trust owns. This often includes:

• Real property (homes, rental properties, land)
• Bank and brokerage accounts
• Business interests
• Personal property of value

Make sure real estate is insured, accounts are retitled or transferred into your name as trustee, and nothing is left unmanaged or vulnerable to loss.

Step 4: Obtain a Tax ID and Open a Trust Bank Account

Most trusts need a new Employer Identification Number (EIN) once they become irrevocable. You’ll use this to open a dedicated trust checking account — never commingle trust funds with your personal accounts. Every dollar coming in or going out should flow through this account to maintain a clean, defensible record.

Step 5: Pay Debts, Expenses, and Taxes

Before distributing anything to beneficiaries, the trustee must address the decedent’s valid debts, final expenses, and tax obligations, including:

• Outstanding personal debts and final medical or funeral bills
• Property taxes and mortgage payments on trust real estate
• Final individual income tax return and any trust income tax returns

Step 6: Keep Accurate Records and Provide Accountings

California law generally requires trustees to provide beneficiaries with an accounting at least annually, and again at the end of administration, unless the trust waives this requirement. Detailed records of every transaction protect you from claims of mismanagement and fulfill your fiduciary duty of transparency.

Step 7: Distribute Trust Assets to Beneficiaries

Once debts, taxes, and expenses are resolved, remaining assets can be distributed according to the trust’s terms. Depending on the trust, this might mean an outright distribution, staggered payments at certain ages, or ongoing trust management for a beneficiary’s benefit.

Common Mistakes Successor Trustees Make

• Delaying or skipping the required beneficiary notice
• Mixing personal and trust funds
• Distributing assets before debts and taxes are settled
• Failing to keep documentation of decisions and expenses
• Trying to handle complex tax or legal issues without professional guidance

These missteps can expose a trustee to personal liability, even when unintentional. Because a trustee owes a fiduciary duty to beneficiaries, courts hold trustees to a high standard of care.

When to Bring in an Attorney

Trust administration can range from straightforward to highly complex, particularly when real estate, business interests, blended families, or potential disputes are involved. An experienced trust administration attorney can help you meet your legal deadlines, minimize personal risk, and move the process forward efficiently.
