Co-Trustee Deadlock in California: Rules and Removal Options

Two co-trustees disagree about repairing a leaking roof in a San Jose ranch home.

A California court may remove a co-trustee when lack of cooperation impairs trust administration or other qualifying circumstances exist. Unless the trust provides otherwise, co-trustees generally must act unanimously; if they cannot resolve an administration issue, a trustee or affected beneficiary may petition for instructions under Probate Code § 17200, according to the California Legislature. These are key co-trustee deadlock resolution mechanisms under California law, and delay that harms trust administration may also expose a trustee to a breach-of-duty claim.

A disagreement can feel like a family conflict, but it can also affect trust assets and the beneficiaries who depend on them. Removing a co-trustee is not always the answer: the trust’s decision-making terms, the nature of the dispute, and its impact on administration all matter.

This article explains California’s default voting rule, what the trust may provide for tie-breaking or delegated authority, and when court instructions or removal may be appropriate. It also explains the risks of inaction, so you can assess your options before a stalled decision causes further problems.

Key Takeaways

  • Removal may be an option when a co-trustee’s conduct or lack of cooperation impairs trust administration; court instructions can address unresolved decisions.
  • California’s default rule generally requires co-trustees to act unanimously, unless the trust provides a different decision-making method.
  • Review the trust’s terms for authority to act independently, delegate tasks, or use a tie-breaking process before treating a stalled decision as resolved.
  • Address deadlocks before delay harms trust administration, and seek trustee advisory guidance when you need help understanding the available options.

Can a Deadlocked Co-Trustee Be Removed?

A court may intervene when a co-trustee dispute prevents necessary administration or threatens trust property or beneficiaries. Removal is one possible remedy, but the court may consider narrower relief that addresses the specific problem.

Court Intervention for Harmful Deadlock

Court intervention may be appropriate when an impasse has a practical effect on the trust, not merely because trustees disagree. For example, records showing an unresolved decision and a missed obligation can help demonstrate the problem. A court may consider removal if a trustee’s lack of cooperation impairs administration or another qualifying circumstance exists. Tie the requested remedy to the harm the deadlock is causing.

Petitions for Court Instructions

A petition for instructions asks the court to answer a trust-administration question. A co-trustee or affected beneficiary can petition a California probate court for instructions under Probate Code § 17200 to resolve a trust administration question, according to the California Legislature. This may be a focused way to seek direction about a disputed action or authority. It does not make removal the only available request.

Other relief may address a different concern. For example, a court may suspend a trustee’s powers to the extent necessary while a removal petition is pending if loss or injury may occur, under Probate Code § 15642(e). A Heggstad petition serves a separate purpose: it asks the court to determine whether an asset belongs to a trust, rather than resolve a co-trustee deadlock.

Before filing, organize the trust terms, written communications, and records showing the effect of the disagreement. These materials can help distinguish a dispute that needs guidance from conduct that may justify removal. Clearly describe the relief sought and how it relates to trust administration and the beneficiaries’ interests.

What Is California’s Default Rule for Co-Trustee Decisions?

California Probate Code section 15620 generally requires unanimous action when two or more trustees hold a power, unless the trust instrument provides otherwise. Section 15621 addresses limited situations where remaining trustees may act because immediate action is needed to carry out the trust’s purposes or prevent harm to trust property. These provisions are central to co-trustee deadlock resolution mechanisms under California law.

If the trust requires unanimous approval, every co-trustee whose agreement is required must approve the action. A split vote is not approval simply because one trustee believes the decision benefits the beneficiaries. Until the required agreement exists, do not assume that acting alone is authorized.

The trust document may set a different process. It might allow a co-trustee to handle specified tasks independently or require joint approval only for major decisions. Read the terms closely: authority to manage routine administration alone does not automatically cover a different, significant action.

For example, a trust might let one co-trustee arrange routine maintenance while requiring both trustees to approve a property sale. The trust terms determine the scope of each trustee’s authority. If the wording is unclear, identify the proposed action and the clause each trustee relies on. This can help distinguish a genuine deadlock from a disagreement over the document’s meaning.

Section 16012(b) allows delegation when the trust terms permit it, while the delegating trustee retains a duty of general supervision. Delegation doesn’t erase oversight responsibilities. Recording the task, its limits, and follow-up can clarify who remains responsible. Understanding these co-trustee deadlock resolution mechanisms under California law can help trustees avoid treating silence or a stalled discussion as permission to act.

If you need help understanding how the document allocates authority, discuss co-trustee decision-making.

Can Trust Terms Allow Majority Decisions or Tie-Breaking Authority?

A majority of co-trustees can act despite one trustee’s disagreement only if the trust authorizes majority decisions or another applicable provision permits that action. A tie-breaking process must come from the trust terms or a court’s direction, not simply from one trustee’s preference.

Alternatives to Unanimous Decision-Making

A trust can establish decision rules to help trustees move forward when they disagree. For example, it may allow a majority to approve routine administration while requiring unanimous consent for a property sale. It may also describe a process for resolving a specific issue. The exact wording controls which decisions fall within that authority.

Before relying on a majority vote, identify the decision at issue, the number of serving trustees, and the trust clause authorizing the vote. A trust with three trustees might allow two to approve a covered action, but the trustee count alone does not establish that rule. Keeping a written record of the vote and its basis can clarify how the decision was made.

Deadlock and Delayed Joint Decisions

A deadlock occurs when the trustees whose agreement is required cannot agree, leaving trust administration stalled. Even routine delays can have consequences if, for example, co-trustees cannot approve a necessary property repair or decide whether to proceed with an asset sale. The longer the conflict prevents action, the harder it may be to protect trust property and keep administration moving.

The trust’s terms may provide a way to address a disagreement or change how decisions are made. Any available option depends on the document and the circumstances. If the document provides no workable tie-breaker, discuss the trust’s decision rules before a stalemate leads to litigation or a potential breach of duty.

How Can Delay Harm a Trust and Create Fiduciary Liability?

A deadlock can expose trust assets to risk, delay beneficiary distributions, or prevent payment of necessary expenses. Each co-trustee remains responsible for participating in proper administration, even when the trustees disagree.

Harm to Trust Assets from Delay

Delay can harm trust property when a necessary decision remains unresolved. For example, co-trustees unable to approve an asset sale may miss a useful opportunity, while a stalled repair decision can leave real property vulnerable to further damage. Distributions, expenses, and tax-related decisions may also be delayed. Track the pending action, its effect on the trust, and the steps taken to resolve the dispute.

California Probate Code Section 16420 provides remedies for a breach or threatened breach of trust, and Section 16440 addresses losses and other amounts that may be charged to a trustee for breach. A probate petition may seek relief when inaction threatens trust property or beneficiary interests.

Co-Trustee Participation and Fiduciary Duties

Co-trustees share fiduciary duties and cannot simply leave all administration to one person. When one trustee handles a delegated task, the other still has supervisory responsibilities and must remain engaged. For example, a co-trustee who receives account information should review it and follow up on concerns about an unexplained payment or missed obligation.

Section 16062 concerns trustee accounting obligations. A co-trustee’s refusal to provide information or cooperate can make an accurate account harder to prepare. If a trustee suspects a breach, documenting the concern and communicating it in writing can help show that the issue was raised and addressed rather than left unattended.

If conflict prevents necessary decisions, court intervention may include suspending a trustee’s powers or appointing a temporary trustee to protect administration while a removal petition is pending. The appropriate legal remedy depends on the risk, the trust terms, and the relief sought.

Discuss fiduciary concerns## How Can Law Offices of Robert P. Bergman Help With Trustee Advisory Services?

Law Offices of Robert P. Bergman provides Trustee Advisory Services to people who need guidance in their trustee role. This service can help you approach a difficult administration issue, organize relevant information, and understand your responsibilities before deciding what to do next.

Advisory guidance can help clarify the practical details. For example, you may need to explain what happened, identify records related to the issue, and specify which decision remains unresolved. A clearer picture can help you understand the options you are considering and communicate effectively with the other people involved.

Trustee advice is different from a court decision. It can help you understand a trust-administration issue and consider possible next steps, but it cannot decide a dispute for a judge or ensure that another trustee will agree. If the matter requires a court ruling or involves contested litigation, it is important to distinguish private guidance from court relief.

Consider advisory support if you are serving as a trustee and feel uncertain about handling an administrative concern, communicating with beneficiaries, or keeping records organized. You can discuss the specific situation and the questions you need answered, rather than trying to resolve every family disagreement at once.

A clear understanding of your role can help you approach the next conversation with greater confidence and care.

Set Up the Next Decision With Clarity

A trustee disagreement can prompt a useful question: could clearer planning help your family avoid the same uncertainty in the future? Understanding co-trustee deadlock resolution mechanisms under California law can also inform how you select trustees and define their roles in your estate plan.

Law Offices of Robert P. Bergman offers Revocable Living Trusts, Wills, and Durable Power of Attorney for Property as part of custom estate planning. These documents address different aspects of an estate plan, and coordinating them can clarify responsibilities. If you are considering a new plan or reviewing an existing one, consider who should make decisions, what authority each person needs, and how a successor can step in.

For a current deadlock, keep the discussion focused on the specific decision and the trust terms that apply. A clear next step can help you understand your options and move forward.

Frequently Asked Questions

Can One Co-Trustee Act Without the Others?

Start by identifying the specific task, not just the trustee’s general role. A clause authorizing one trustee to manage investments, for example, may not cover signing a deed or changing a distribution. Keep a copy of the relevant trust provision with records of the proposed action. If immediate action is needed to protect trust property, Probate Code section 15621 may be relevant.

What Happens When Multiple Co-Trustees Can’t Agree?

Try narrowing the disagreement to a specific decision and the information each trustee needs to evaluate it. The trustees can prepare a written proposal, gather relevant records, and compare the options with the trust’s terms and the beneficiaries’ interests. If discussion remains unproductive, document each trustee’s position and the steps taken to resolve the issue. Keep proposals and responses together to record the disagreement and attempted solutions.

What Happens When Sibling Co-Trustees Disagree?

Sibling trustees can make the conversation more manageable by separating family history from the trustee decision. For example, ask each sibling to explain the practical concern behind a proposed property sale, then compare those concerns with the trust’s purpose and the beneficiaries’ interests. Each sibling can share relevant information and propose a practical next step. If they still cannot agree, they can seek court relief.

Co-trustees should keep records that allow the trust’s financial activity to be understood, including receipts, transaction details, and communications about significant decisions. California Probate Code section 16062 addresses a trustee’s accounting obligations. Organized records can help trustees prepare an account and explain what happened to trust assets. They also give beneficiaries clearer information about administration and help identify questions that need attention.

When Is Court Intervention Necessary?

Court involvement may become necessary when the trustees cannot resolve an administration question and a decision or protective measure is needed. A trust petition generally requires notice to trustees and beneficiaries at least 30 days before the hearing, subject to statutory notice provisions, according to the California Legislature. That notice period is a practical consideration when planning a request for court relief.

Why Do “Equal Control” Arrangements Often Create Conflict?

Equal authority can leave roles unclear even before a disagreement arises. A trust can reduce uncertainty by distinguishing routine tasks from decisions affecting major assets or beneficiary rights, and by establishing a process for resolving a tie. For future planning, families can also consider whether one trustee with a clearly designated successor would suit their needs better than shared control.
