Only if the delay was a breach of trust. Interest isn’t automatic compensation for waiting, and that distinction is where most beneficiary complaints about slow trustees fall apart. Where the delay was itself wrongful, interest follows and the statute sets the rate.
When does a trustee owe interest?
Prob. Code § 16440(a) makes a trustee who commits a breach of trust chargeable with any loss or depreciation in value resulting from the breach, with interest, and with any profit the trustee made through the breach, also with interest.
Read the trigger carefully. It’s breach, not delay. A trustee who took eleven months because a house wouldn’t sell owes you nothing extra. A trustee who sat on $500,000 in a non-interest-bearing account for three years while ignoring your letters is a different case.
How much interest?
Section 16441 sets it as the greater of two amounts: interest at the legal rate on judgments in effect during the period when the interest accrued, or the amount of interest actually received.
The “actually received” prong matters more than people expect. If the trustee parked trust money somewhere earning a real return and kept the return, that’s the number, and § 16440(a)(2) reaches profit the trustee made through the breach regardless.
Can the trustee get out of it?
Yes, and this is the provision beneficiaries overlook. Both sections carry the same escape hatch: if the trustee acted reasonably and in good faith under the circumstances as known to them, the court may in its discretion excuse the trustee in whole or in part where it would be equitable.
So a well-meaning family trustee who was slow because they were overwhelmed and grieving has a real defence. A trustee who was slow because they were living in the house and drawing a fee does not.
That is why the useful question is never “how long has it been.” It’s “what was the trustee doing during that time, and who benefited.”
What counts as a breach that produces interest?
The recurring ones in California trust practice:
- Failing to make trust property productive, such as leaving large sums in a zero-interest account for years
- Letting a beneficiary occupy trust real property rent free while others wait
- Using trust funds for the trustee’s own purposes, which is a § 16004 problem before it’s an interest problem
- Refusing to distribute after every reason for holding has expired
- Failing to account, where that failure concealed the delay
Notice that most of these are the same facts that support removal under § 15642. Interest is usually a component of a surcharge claim rather than a standalone action.
How do I actually claim it?
Through a petition under § 17200, and almost always after an accounting rather than before. You need the dates and balances to compute anything, and those live in the accounting.
The sequence that works: demand the accounting in writing, get it or petition for it, identify the periods where trust funds sat idle or were misused, then bring the surcharge claim with interest as a component.
Watch the clock. Under § 16460, a claim is barred three years after you received an account or report that adequately disclosed it, or three years after you discovered or reasonably should have discovered it where no adequate account arrived.
Is it worth pursuing?
Often not on its own. Interest at the legal rate on a share that was late by a year is real money but rarely enough to fund litigation by itself.
Where it earns its place is as one component of a larger surcharge: excessive fees, rent-free occupancy, a self-dealing sale, and the interest on all of it. Bundled that way it’s worth having. Chased alone it usually isn’t, and a lawyer who tells you otherwise on a small delay is not doing you a favour.
