Understanding the Trust Administration Process

  • Published: June 7, 2026

When a loved one passes away, serving as trustee can feel overwhelming. Trust administration involves legal duties, strict deadlines, and detailed financial responsibilities. Below is a general overview of the trust administration process in California and what trustees should expect. A Orange, CA trust administration lawyer can help trustees navigate these responsibilities, comply with California law, and efficiently manage the administration process.

Step 1: Obtain a Tax Identification Number (EIN)

After the settlor’s death, the trustee must obtain a new Employer Identification Number (EIN) for the trust by filing IRS Form SS-4. The trust becomes a separate tax entity, and the decedent’s Social Security number may no longer be used.

The trustee may also need to file Form 56 to notify the IRS of the fiduciary relationship and, during administration, file fiduciary income tax returns (Form 1041).

Step 2: Provide Required Legal Notices

California law imposes strict notice requirements.

Under Probate Code §16061.7, the trustee must provide formal notice to all beneficiaries and heirs within 60 days of the settlor’s death. This notice must include:

  • The identity of the settlor and date of execution of the trust
  • The name, address, and phone number of each trustee
  • The address where principal trust administration occurs
  • A statement that recipients are entitled to a complete copy of the trust

Once notice is given, beneficiaries generally have 120 days to contest the trust.

Additionally, notice must be sent to the California Department of Health Care Services (DHCS), along with a copy of the death certificate. DHCS has four months to file a claim.

Step 3: Marshal and Protect Trust Assets

The trustee must identify, collect, and safeguard all trust assets. This often includes:

  • Retitling financial accounts
  • Transferring real property
  • Securing personal property
  • Reviewing outstanding debts and liabilities

If funds are deposited into financial institutions, they must generally be placed in insured, interest-bearing accounts.

Trustees may also notify known creditors and, if appropriate, publish notice. Creditors typically have four months to bring a claim.

Step 4: Exercise Trustee Powers

Trustees have broad authority under California law and the trust document. In most cases, court permission is not required to:

  • Sell or acquire property
  • Manage, lease, or improve trust assets
  • Borrow funds or encumber property
  • Pay debts and taxes
  • Hire professionals such as attorneys, accountants, or appraisers

In some situations, a trustee may provide a Notice of Proposed Action (NOPA) before taking certain actions. Beneficiaries must be given at least 45 days to object. If an objection is received, the trustee or beneficiary may petition the court for approval.

Step 5: Trust Accounting

Trustees have a duty to provide accounting to beneficiaries. Accountings are typically required:

  • Annually
  • Upon termination of the trust
  • Upon change of trustee

A proper trust accounting details income, expenses, distributions, and trust assets.

Step 6: Final Distribution

Once debts, taxes, and administrative matters are resolved, the trustee may distribute the remaining trust assets to beneficiaries in accordance with the trust terms.

Final distribution typically includes:

  • A distribution letter
  • A check or asset transfer
  • A signed receipt from the beneficiary

Why Professional Guidance Matters

Trust administration involves legal compliance, tax filings, creditor issues, and fiduciary duties. Mistakes can lead to personal liability for trustees and unnecessary conflict among beneficiaries.
