California trusts sometimes name two or more persons as co-trustees, giving each co-trustee a voice in the administration and providing a check on any single trustee’s authority. This structure works well when the co-trustees can cooperate, but when the co-trustees disagree about fundamental administration decisions, the trust administration can become deadlocked in ways that harm all beneficiaries. California Probate Code provides specific mechanisms for addressing co-trustee conflicts, including the removal of a co-trustee whose conduct is preventing effective administration, and the appointment of a neutral third-party trustee to replace one or both co-trustees when the conflict cannot otherwise be resolved. Understanding when a co-trustee conflict justifies removal and what legal tools are available to break the deadlock is essential for beneficiaries and co-trustees facing this situation.
The California Rule for Co-Trustee Decision Making
California Probate Code Section 15620 establishes the default rule for co-trustee decision making: when a trust has multiple trustees, the trustees must act unanimously unless the trust instrument provides otherwise. This unanimity requirement creates co-trustee deadlock: when two co-trustees hold completely opposing views on a major administrative decision, neither can implement a decision. Some trust documents provide for majority rule among three or more co-trustees, which reduces but does not eliminate the deadlock risk. When the trust document provides no majority rule option, and the co-trustees cannot agree, the probate court has authority under Probate Code Section 17200 to resolve the specific dispute and to order whatever administration action is in the best interests of the beneficiaries.
When Deadlock Justifies Removal of a Co-Trustee
California Probate Code Section 15642(b)(6) specifically authorizes removal of a trustee when the trustee is unable to cooperate with co-trustees in a manner that is detrimental to the trust. This removal ground differs from the breach of trust ground because it focuses on a breakdown in the co-trustee relationship rather than specific wrongful conduct by the trustee. Courts have applied this ground when one co-trustee has made the trust’s effective administration impossible through persistent obstruction, bad-faith refusal to participate in trust decisions, or conduct specifically designed to create gridlock that benefits the obstructing trustee at the expense of the trust’s beneficiaries.
Appointing a Neutral Co-Trustee or Sole Trustee
When the co-trustee conflict is so severe that removing one co-trustee would simply shift the administration problem to the remaining trustee, courts sometimes resolve the situation by replacing both co-trustees with a neutral professional or institutional trustee. A corporate trust department or professional trustee with no pre-existing relationship with any beneficiary or family member can administer the trust without the loyalties and conflicts that produced the co-trustee deadlock. This solution is more disruptive than removing a single co-trustee but provides the clean break from the dysfunctional administration that some trust conflicts require.
The California Legislature’s Probate Code Section 15642 establishes the co-trustee conflict removal ground. Working with an experienced trustee removal lawyer who understands the co-trustee dynamics and the specific tools available to break administrative deadlock gives beneficiaries facing these situations the effective legal solutions their trust requires.
