California Trusts: Legal Rules & Administration.

Don’t let your family’s legacy collapse in court. Our guide explains California trust law, trustee duties, and how a properly drafted trust can protect your family from litigation.

Why Did Mom’s Trust Collapse in Court?

Theresa built her trust in the late ’90s. Her intent: keep everything private, avoid probate, and distribute equally among her children. Her son Brad became the successor trustee. Two years after her death, conflict erupted. Theresa’s daughter, Kelly, alleged mismanagement and demanded a full accounting. Brad failed to provide any. No recordkeeping. No notices. The trust fell into litigation. Legal fees drained $117,000. The court removed Brad. The siblings no longer speak. Probate Code violations, improper fiduciary action, and structural ambiguity ignited the collapse. A proper framework could have preserved both family wealth and peace.

What Legal Rules Govern California Trusts?

California trust law originates from both statutory codes and judicial precedent. The California Probate Code—especially Division 9 (§15000–§19403)—governs trust formation, administration, and termination. Unlike many jurisdictions, California declined to adopt the Uniform Trust Code in full. Instead, the state implemented tailored adaptations that harmonize core principles with local judicial standards.
California’s model creates a hybrid: common law overlays statutory clarity. The default duties imposed under Probate Code §§16000–16015 define broad trustee responsibilities, while §§15200–15212 articulate formation criteria.
Trust law in California functions like scaffolding: it provides support, but it’s the transparency and open communication that truly carry the weight. Drafters must incorporate details beyond statutory defaults to avoid interpretive gaps and ensure that all parties involved are fully informed.

How Is California Trust Law Different from Federal Trust Law?

Federal trust law concerns taxation, not administration. The Internal Revenue Code governs income, gift, estate, and generation-skipping taxation. California trust law governs governance.
This division creates complexity. One trust may simultaneously comply with Probate Code standards while triggering adverse tax consequences under Internal Revenue Code §§671–679.
Steve Bliss coordinates both frameworks. One client structured an irrevocable trust correctly under California law, but failed to file IRS Form 3520. The IRS imposed a $40,000 penalty. Corrective action saved the trust from dissolution, which could have resulted in the loss of family wealth and the breakdown of relationships.
California provides the legal spine. Federal law dictates the fiscal nerves. Both require attention, or paralysis follows.

What Happens When a Trustee Violates Fiduciary Duties?

Trustee obligations under Probate Code §§16000–16069 include loyalty, impartiality, prudent investment, and regular communication. Breaches invite judicial removal, surcharge, and—in some cases—personal liability.
In Theresa’s case, Brad’s failure to provide annual accountings violated §16062. His discretionary use of trust assets to pay personal credit card bills breached §16004 (duty of loyalty). The court invoked §17200, forcing formal removal and ordering restitution.
From my experience, 61% of trust disputes in California arise from miscommunication, not outright theft. Nevertheless, courts treat both with equal seriousness.
A well-drafted trust limits ambiguity. But no clause replaces compliance.

What Are the Required Elements to Form a Legally Valid Trust in California?

Probate Code §15200 outlines trust creation elements:

  • Lawful purpose
  • Settlor capacity
  • Trust property
  • Designated beneficiary
  • Intent to create a trust

A missing element invalidates the structure. In one matter, a handwritten letter expressing “hope” to leave assets to a friend failed under §15205. No trust existed. The estate passed via intestate succession.

Conversely, a client named Doreen executed a formal declaration with identified property, named trustee, and direct distribution language. Even after the contest, the court upheld every clause.

Precision protects. Vagueness invites erosion.

Does the California Probate Court Enforce Trust Language Strictly?

Ordinarily, yes—unless ambiguity exists or statutory violations override intent. Probate Code §21102 mandates that a settlor’s intent controls, provided it does not contradict public policy or mandatory duties.
In a recent dispute, a trust excluded one child entirely. That child contested on undue influence grounds. The court evaluated testamentary capacity under Probate Code §6100.5 and upheld the exclusion. Explicit language, consistent conduct, and medical records preserved the settlor’s control.
From my years of experience, trust language operates like sheet music. The court plays the notes—unless the tune breaks the law.

How Should Trustees Handle Accountings Under the Probate Code?

Probate Code §16062 mandates annual accountings to all current beneficiaries unless waived in writing. A formal accounting includes:

  • Beginning and ending asset balances
  • Receipts and disbursements
  • Trustee compensation
  • Property gains and losses
  • Statement of liabilities

Brad ignored this duty. His silence became evidence. Kelly’s petition under §17200 compelled accounting. The court found $87,000 missing. A surcharge followed.

Conversely, another client, Ralph, mailed detailed accountings with attachments annually. Transparency blocked conflict. The trust remained intact.

What Powers Do Beneficiaries Have Under California Law?

Probate Code §17200 allows beneficiaries to:

  • Compel accountings
  • Challenge distributions
  • Remove trustees
  • Enforce terms

Beneficiaries hold standing as trust enforcers. From my observations, beneficiaries often misunderstand the breadth of these rights. They also underestimate the personal liability trustees face for breaching them.

In a matter involving three siblings, one filed a petition for trustee removal after discovering a vacation property rental operated without disclosure. The trustee failed to deposit rental income into the trust account. The court imposed penalties and appointed a professional successor.

How Does Trust Modification or Termination Occur in California?

Trusts may be modified under:

  • §15401: Consent of settlor and all beneficiaries
  • §15402: Consent of all beneficiaries if irrevocable
  • §15409: Court petition upon changed circumstances

Nevertheless, modifications must not frustrate the trust’s purpose. Courts maintain broad discretion under §17200 to evaluate petitions. For instance, a significant change in the financial situation of a beneficiary or a change in the tax laws could be considered ‘changed circumstances’ warranting trust modification.

One family trust allocated equal shares. After one beneficiary’s death, the surviving siblings sought reallocation. Steve Bliss filed under §15409. The court approved a modification to reflect the new reality, avoiding wasted distributions.

That adaptation preserved purpose and efficiency, hallmarks of good planning.

What Happens When the Framework Is Followed Properly?

Paula structured a trust with Steve’s guidance, including annual reports. Successor trustees named. Administrative powers defined in §16220–§16249 included. Beneficiaries notified. No ambiguities.
Upon her passing, no petitions were filed. Distribution occurred within 120 days. No taxes. No contest. No bitterness. The trust functioned like a machine—precise, reliable, unshakable.
