Trust administration is the process of carrying out the terms of a trust after the trustee begins acting, most commonly after the death of the settlor of a revocable living trust or when a successor trustee takes over management of trust assets. Unlike probate, trust administration is often handled outside a full court-supervised estate proceeding, but it still involves legal duties, required notices, asset identification, recordkeeping, possible accountings, tax coordination, and careful communication with beneficiaries. At Westlake Law Group, we assist trustees, beneficiaries, and families throughout Westlake Village, Thousand Oaks, Calabasas, Ventura County, and Los Angeles County with California trust administration, including post-death administration, successor trustee transitions, trust accountings, beneficiary-rights issues, and trust-related disputes.
Trust administration can become complicated quickly when real estate must be managed or sold, financial institutions require proof of authority, records are incomplete, the trust was not fully funded, distributions are disputed, or beneficiaries question the trustee's conduct. If you need help with trust administration in Southern California, call (818) 444-2022 to schedule a confidential consultation.
What Is Trust Administration?
Trust administration is the process of managing and distributing trust assets under the terms of the trust instrument and California law. In many families, this begins after a settlor dies and the successor trustee must step in, gather trust documents, identify trust assets, determine what property is actually titled in the trust, communicate with beneficiaries, handle debts and expenses, and eventually make distributions.
A living trust is often used to avoid a full probate administration for assets that were properly transferred into the trust during life. For basic background on living trusts and probate avoidance, California Courts provides general information here:

Common Tasks in California Trust Administration
Trust administration commonly includes:
- Reviewing the trust and all amendments
- Confirming who is serving as current trustee
- Identifying beneficiaries and their interests
- Locating and securing trust assets
- Determining which assets are actually titled in the trust
- Handling trust-owned real estate, bank accounts, brokerage accounts, and business interests
- Obtaining date-of-death values and financial information
- Providing required notices to beneficiaries and heirs
- Responding to requests for information and accountings
- Paying proper expenses, debts, and taxes
- Preparing distribution plans and reserve decisions
- Coordinating partial or final distributions
- Documenting the administration in a way that can withstand beneficiary scrutiny
If the estate includes significant assets outside the trust, a probate proceeding may still be required for those separate assets. For related information, see:

When Trust Administration Begins After Death
Many California trust administrations begin when a revocable trust becomes irrevocable after the death of a settlor and the successor trustee must begin acting. That transition can involve both legal and practical steps. The trustee often needs to gather the trust, death certificate, schedules, amendments, deeds, statements, business records, and beneficiary contact information before institutions will recognize authority.

Trustee Notice Requirements and Deadlines
California trust administration is not just informal paperwork. After the death of a settlor in many revocable trust situations, the trustee may be required to serve a statutory notification on beneficiaries and heirs. Probate Code section 16061.7 addresses notification by trustee:
https://leginfo.legislature.ca.gov/faces/codes_displaySection.xhtml?lawCode=PROB§ionNum=16061.7
When that notice is properly served, it can trigger limitation periods for certain trust actions. Probate Code section 16061.8 addresses those timing rules:
https://leginfo.legislature.ca.gov/faces/codes_displaySection.xhtml?lawCode=PROB§ionNum=16061.8
Because notice problems and deadline issues can affect contests and other claims, it is important to review the timing, the documents served, and the trust terms early in the administration.
Trustee Duties During Administration
A trustee is not simply a family helper or asset holder. A trustee is a fiduciary and must administer the trust according to the trust instrument and California law. Key statutory duties include the duty to administer the trust according to the trust instrument, the duty of loyalty, the duty of impartiality among beneficiaries in appropriate cases, and the duty of prudent administration.
Probate Code section 16000 addresses the duty to administer according to the trust:
https://leginfo.legislature.ca.gov/faces/codes_displaySection.xhtml?lawCode=PROB§ionNum=16000
Probate Code section 16002 addresses the duty of loyalty:
https://leginfo.legislature.ca.gov/faces/codes_displaySection.xhtml?lawCode=PROB§ionNum=16002
Probate Code section 16003 addresses impartial treatment of beneficiaries:
https://leginfo.legislature.ca.gov/faces/codes_displaySection.xhtml?lawCode=PROB§ionNum=16003
Probate Code section 16040 addresses prudent administration:
https://leginfo.legislature.ca.gov/faces/codes_displaySection.xhtml?lawCode=PROB§ionNum=16040
For a general educational discussion of fiduciary obligations, Cornell Law School's Legal Information Institute provides background here:
https://www.law.cornell.edu/wex/fiduciary_duty
In practice, trust-administration problems often arise when a trustee delays communication, mixes trust assets with personal assets, makes undocumented reimbursements, favors one beneficiary over another, fails to secure real property, or makes distributions before administration is actually ready to close.
Beneficiary Information Rights and Trust Accountings
One of the most common trust-administration issues is lack of transparency. California law requires trustees to keep beneficiaries reasonably informed and, in many circumstances, to provide accountings. Probate Code section 16060 addresses the duty to keep beneficiaries reasonably informed:
https://leginfo.legislature.ca.gov/faces/codes_displaySection.xhtml?lawCode=PROB§ionNum=16060
Probate Code section 16062 addresses the trustee's accounting duty:
https://leginfo.legislature.ca.gov/faces/codes_displaySection.xhtml?lawCode=PROB§ionNum=16062
Accountings are often central to post-death trust administration, especially when the trust holds brokerage accounts, multiple parcels of real estate, rental income, business interests, loans to family members, or large reimbursements.

Certification of Trust and Proof of Trustee Authority
Banks, title companies, escrow officers, and financial institutions often want proof that the acting trustee has authority to deal with trust assets. In many cases, that proof is provided through a certification of trust rather than by turning over the full trust instrument. Probate Code section 18100.5 addresses certification of trust:
https://leginfo.legislature.ca.gov/faces/codes_displaySection.xhtml?lawCode=PROB§ionNum=18100.5
Certification issues frequently arise during trust administration involving:
- Sales or refinancing of trust real estate
- Transfers of financial accounts
- Successor trustee transitions
- Requests from title companies and lenders
- Review of powers before signing transaction documents
Trust Administration and Real Estate
Real estate often drives the most difficult part of a California trust administration. Even when a house is titled in the trust, the trustee still has to determine occupancy issues, insurance status, carrying costs, repair decisions, listing strategy, sale timing, beneficiary expectations, and whether the trust permits unequal distributions or special treatment of particular property.
If title is held in the name of a now-deceased trustee, an affidavit of death of trustee may be part of clearing the chain of title for trust administration involving California real property.
When administration involves sale proceeds, reimbursements, reserve decisions, or questions about what happened to trust money, disputes often expand into accounting and beneficiary-rights issues.
When Court Intervention Becomes Necessary
Although trust administration is often handled without opening a probate estate, probate court may still become involved when instructions are needed, accountings are disputed, beneficiary rights must be enforced, or trustee conduct is challenged. Probate Code section 17200 authorizes petitions concerning the internal affairs of a trust, including petitions involving trustee actions, beneficiary rights, accountings, construction of trust terms, and administration issues:
https://leginfo.legislature.ca.gov/faces/codes_displaySection.xhtml?lawCode=PROB§ionNum=17200
Probate Court Procedure, Rules, and Forms
Trust-related court petitions are typically handled in the Probate Division of the Superior Court. Useful official resources include:
California Legislative Information:

Even when no court petition is filed initially, trustees and beneficiaries often need to understand how probate court rules and procedures can affect strategy, timing, and leverage if a dispute later develops.
