Frequently asked questions

What is a successor trustee?

A successor trustee is the person or institution named in a trust instrument to take over the trust when the original trustee dies, resigns or becomes incapacitated. A co-trustee, by contrast, serves at the same time as another trustee rather than afterward.

What happens when co-trustees disagree?

Ordinary disagreement can usually continue without court involvement, but hostility or lack of cooperation that impairs the trust's administration is one of the grounds for removal in Probate Code section 15642(b). A beneficiary or co-trustee may petition under section 17200, and the court may appoint a temporary trustee under section 17206.

Can a successor trustee be removed in California?

Yes. Under Probate Code section 15642(a), removal may happen under the trust instrument, by the court on its own motion, or on a section 17200 petition of a settlor, co-trustee or beneficiary. Grounds include breach of trust, unfitness, failing or declining to act and excessive compensation; the court decides on the evidence.

What type of trust cannot be changed?

An irrevocable trust is one the settlor can no longer revoke. In disputes, the key moment is often when a revocable trust becomes irrevocable because a settlor dies, which triggers the trustee's notification under Probate Code section 16061.7.

What can a beneficiary do if a successor trustee refuses to provide information?

The beneficiary can make a reasonable written request under Probate Code section 16061. If the trustee fails to provide the information within 60 days and the beneficiary has not received it within the six months before the request, a petition to compel is available under section 17200(b)(7).

How long does a beneficiary have to contest a trust in California?

For a person served with the trustee's notification after a settlor's death, Probate Code section 16061.8 bars a contest brought more than 120 days after the notification is served, or 60 days after a copy of the trust terms is delivered during that 120-day period, whichever is later.

What remedies are available if a successor trustee breaches their duties?

Probate Code section 16420(a) allows proceedings to compel performance, enjoin a breach, compel payment or other redress, appoint a receiver or temporary trustee, remove the trustee, reduce or deny compensation and, subject to section 18100, set aside acts, impose a lien or constructive trust, and trace property. Other remedies remain available; none is automatic.

How long does a beneficiary have to bring a breach of trust claim?

Under Probate Code section 16460(a), three years after receiving an account or written report that adequately discloses the claim; or, if none discloses it or none is received, three years after the beneficiary discovered or reasonably should have discovered the subject of the claim.
