When someone with a trust passes away in California, the trust keeps assets out of probate. That’s part of the reason why people create one in the first place. But what happens to the trust after you pass? A revocable trust may become irrevocable, and a successor trustee is going to take over. Understanding how this all works can help you plan for the future and pick the right person to be your successor trustee.

The Trust Becomes Irrevocable at Death
If you have a revocable living trust, you maintain control over it during your lifetime. You can amend them and control them. But once the grantor dies, that trust becomes irrevocable. This means that no one change its terms unless the trust specifically permits some limited modifications. This helps to protect the grantor’s wishes and protects the assets within it.
At this stage, the trust becomes the controlling document for all assets titled in the trust’s name. Property held outside the trust may still require probate unless it qualifies for a statutory exception.
The Successor Trustee Takes Over
The most significant change after the grantor’s death is the transfer of authority from the original trustee to the successor trustee. This person (or institution) is named in the trust document and is legally responsible for carrying out the trust administration process.
Key Duties of a Successor Trustee in California
Successor trustees must follow California Probate Code requirements and the trust’s instructions. Their responsibilities typically include:
- Locating and reviewing the trust document
- Securing trust assets
- Obtaining a tax identification number (TIN) for the irrevocable trust.
- Providing required notices
- Collecting date-of-death values for all trust assets
- Managing and safeguarding assets during administration
- Maintain insurance
- Pay mortgages
- Oversee trust investments
- Paying valid debts and expenses, including final bills, funeral costs, and administrative expenses.
- Filing tax returns, such as the decedent’s final income tax return and any required fiduciary returns.
- Distributing assets to beneficiaries once all obligations are satisfied.
Trust Administration Timeline in California
While every trust is different, most California trust administrations follow a general sequence:
- First 30–60 Days: Secure assets, notify beneficiaries, obtain the trust’s TIN, and begin gathering financial information.
- First 3–6 Months: Value assets, pay debts, review tax obligations, and prepare an accounting if required.
- 6–12 Months: Complete tax filings, resolve creditor issues, and prepare for distribution.
- Final Distribution: Transfer property to beneficiaries, record deeds, and close trust accounts.
Complex estates—such as those involving real estate sales, business interests, or tax issues—may take longer.

What Happens to Trust Assets?
Trust assets remain under the control of the successor trustee until administration is complete. Common outcomes include:
- Real estate may be transferred directly to beneficiaries or sold, depending on the trust terms.
- Financial accounts are retitled or distributed according to the trust instructions.
- Personal property is allocated as directed or divided by agreement among beneficiaries.
- Business interests may require valuation, management, or liquidation.
