When Is a California Trustee Personally Liable for a Tort?
Contract liability turns on disclosure. Tort liability turns on something entirely different: fault. A trustee who negligently causes an accident while administering the trust faces a very different analysis than a trustee whose independent contractor causes the accident instead — and California’s statute draws that line precisely.
Under California Probate Code §§ 18001 and 18002, a trustee is personally liable for obligations arising from ownership or control of trust property, or for torts committed during trust administration, only if the trustee is personally at fault. No personal fault, no personal liability — the claim proceeds against the trust instead.
The Old Common-Law Rule: Strict Personal Liability
Before the modern statutory approach, the common-law rule (still worth knowing as the MBE baseline) made a trustee strictly liable for every tort connected to trust administration, fault or no fault. If a trustee’s independent contractor negligently injured someone while repairing trust property, the trustee could be sued personally — even though the trustee did nothing wrong. The only relief was indemnification from the trust, and only if the trustee was without personal fault.
That rule treated the trustee almost like a strict-liability insurer for anything touching trust property. It discouraged people from serving as trustees and made routine delegation (hiring contractors, property managers, investment advisors) riskier than it needed to be.
California’s Fault-Based Rule
California rejected strict trustee liability. Under Probate Code § 18001, a trustee is personally liable for obligations arising from ownership or control of trust property only if personally at fault. Under Probate Code § 18002, the same fault requirement governs torts committed during trust administration generally. If the trustee’s own negligence caused the injury, the trustee is personally exposed. If the harm came from an agent’s negligence, an independent contractor’s mistake, or a strict-liability condition of the property itself — with no personal fault by the trustee — liability runs against the trust only.
This is the critical difference from contract liability: contract liability under § 18000 turns on what the third party knew (disclosure). Tort liability under §§ 18001–18002 turns on what the trustee did (fault). Do not merge the two analyses on an exam.
| Common-law rule | California rule (§§ 18001–18002) | |
|---|---|---|
| Standard | Strict liability for all trust-related torts | Personal liability only if trustee personally at fault |
| Agent’s negligence | Trustee personally liable | Trustee not personally liable (absent independent fault) |
| Recovery source if no fault | Trustee’s personal assets, plus possible indemnification | Trust assets directly, no personal exposure |
Worked Example
Priya is trustee of a California trust that owns a small commercial building. She personally drives a trust-owned delivery van to pick up supplies for a tenant improvement project and rear-ends another car at a stoplight, injuring the driver.
Priya is personally at fault — her own negligent driving caused the collision. Under § 18002, she is personally liable to the injured driver, regardless of the fact that she was acting as trustee at the time. Being a trustee does not launder personal negligence into trust-only liability.
Change the facts: Priya instead hires a licensed contractor to repair the building’s roof. The contractor’s employee negligently drops a tool and injures a pedestrian below. Priya did nothing wrong — she reasonably selected and supervised the contractor. Because Priya was not personally at fault, § 18001 and § 18002 mean she is not personally liable; the injured pedestrian’s claim runs against the trust, and trust assets that funded the roof repair are directly reachable.
Common Mistakes to Avoid
- Thinking the fault-based rule always protects the trustee. It only protects a trustee who was not personally negligent. A trustee’s own careless act triggers personal liability under either the old or new rule.
- Confusing tort liability with contract liability. Contract liability hinges on notice/disclosure (§ 18000); tort liability hinges on fault (§§ 18001–18002). These are separate statutes and separate analyses.
- Assuming “representative capacity” means the trustee escapes liability entirely. It means the claim is against the trust, not that no one is liable — the victim can still recover from trust assets.
- Skipping the indemnification question. A trustee who authorized a risk-creating activity in good faith (like hiring the roofer) can often seek reimbursement from the trust for any amount the trustee does end up paying personally.
Frequently Asked Questions
Is a California trustee liable for an independent contractor’s negligence?
Generally no, if the trustee was not personally at fault in hiring or supervising the contractor. Sections 18001 and 18002 limit the trustee’s exposure to situations of personal fault.
What if the trust owns a dangerous property that triggers strict liability?
If liability arises purely from ownership (strict liability, no personal fault), §§ 18001–18002 limit the trustee to representative-capacity liability; the claim reaches trust assets rather than the trustee’s personal estate.
Does a cotrustee who did not participate in a decision share tort liability?
California Probate Code § 18003 protects a non-participating cotrustee (where three or more cotrustees act) and a dissenting cotrustee who properly documents a written dissent, though it does not excuse a cotrustee from liability for failing to discharge that cotrustee’s own duties.
Key Takeaways
- Prob. Code §§ 18001 and 18002 make a California trustee personally liable for property-related obligations and torts only when the trustee is personally at fault.
- The trustee’s own negligence (driving, decision-making) always triggers personal liability, even under the modern rule.
- An agent’s or independent contractor’s negligence, without personal fault by the trustee, limits recovery to trust assets.
- Contract liability (notice-based, § 18000) and tort liability (fault-based, §§ 18001–18002) are analytically distinct — do not conflate them on a bar exam essay.
- Cotrustees who did not participate in a wrongful act, or who properly dissented, get statutory protection under § 18003.
