Co-Trustee Problems: Deadlocks, Unequal Participation, and How to Resolve Them

Overview

Co-trustees usually have the same basic fiduciary duties: follow the trust document, act loyally, protect trust property, keep records, communicate as required, and make prudent decisions. In theory, shared authority can reduce mistakes. In practice, shared authority can also slow decisions, blur responsibility, and create conflict when one trustee is highly engaged and the other is passive, obstructive, or self-interested.

The first step in resolving co-trustee problems is to identify what kind of problem you actually have. Many disputes get worse because the parties treat every disagreement as a personal conflict rather than a governance problem. The solution for a scheduling issue is different from the solution for a suspected fiduciary breach.

Most co-trustee disputes fall into one of these categories:

• Deadlock on a decision: for example, whether to sell a house, retain an investment, make a discretionary distribution, or hire a professional.
• Unequal participation: one trustee does nearly all the work while the other signs documents late, ignores communications, or contributes little.
• Unauthorized action: one co-trustee acts alone when joint action is required.
• Communication breakdown: meetings do not happen, records are not shared, and beneficiaries receive inconsistent messages.
• Conflict of interest concerns: a co-trustee may also be a beneficiary, family member, business partner, or occupant of trust property.
• Trust accounting and transparency disputes: one trustee cannot evaluate decisions because records are incomplete or delayed.
• Personal hostility: the dispute is no longer about administration alone; history between the trustees now shapes every decision.

If you are a co-trustee, it helps to begin with the trust instrument itself. Some trust documents require unanimous action. Others permit majority action, division of functions, delegation in limited circumstances, tie-breaking procedures, or trustee resignation and replacement mechanisms. State law may supply default rules when the trust is silent, but those rules vary. That means the most useful starting question is not “Who is right?” but “What authority structure governs these co-trustee responsibilities?”

Before taking a hard position, review:

• the trust’s language on co-trustee decision-making
• any amendment that changes trustee powers
• notice requirements to beneficiaries
• rules on trustee compensation and reimbursement
• provisions on delegation, resignation, or removal
• state law on co-trustee duties and liability

Trustees who skip this step often create avoidable risk. A co-trustee who refuses to participate may expose the other trustee to delay and expense. But a co-trustee who acts too aggressively without proper authority may create an even larger problem.

Maintenance cycle

Because co-trustee relationships can deteriorate gradually, this topic should be revisited on a regular review cycle rather than only after a blowup. The most effective co-trustee teams treat governance as an ongoing maintenance task.

A simple maintenance cycle can look like this:

1. Review the trust terms at the start of administration

When trustees first begin acting, they should agree on what requires joint approval, what can be handled administratively, what deadlines matter, and when professional advice is needed. This is especially important during the first stages of trust administration after a death, when deadlines, notices, and asset control issues arrive quickly. A useful companion resource is Trust Administration After Death: First 90 Days Checklist.

2. Set a written operating process

Even if the trust does not require a formal governance policy, co-trustees benefit from one. The process can be simple:

• monthly or quarterly check-ins
• a shared document repository
• a rule that material decisions require written summaries
• a response deadline for emails and approvals
• a list of professionals authorized to advise the trustees
• a procedure for documenting disagreement

This reduces the chance that one trustee later claims not to have known what was happening.

3. Keep trust accounting current

Many co-trustee disputes are really recordkeeping disputes. If both trustees can see cash flow, expenses, distributions, tax filings, and asset valuations, arguments become more concrete and easier to resolve. If records are scattered, every question feels suspicious. For practical guidance, see Trust Accounting for Trustees: What Records to Keep and How Often to Report.

4. Reassess decision-making before major transactions

Before selling real property, making a discretionary distribution, settling a beneficiary complaint, changing investment strategy, or filing tax returns, co-trustees should pause and confirm who must approve what. Real estate sales and distributions are common flashpoints because they mix legal authority, timing, and family expectations.

5. Document concerns early

If one co-trustee is not participating or appears to be overstepping, write down specific examples, dates, and impact on administration. Avoid emotional labels. A short factual memo is more useful than a long accusatory email. This record may later support mediation, resignation planning, legal advice, or a petition to remove a trustee.

6. Refresh the process when conditions change

A trust that was easy to manage while assets were static may become harder when a house must be sold, tax filings come due, or beneficiaries begin asking for distributions. The governance process should evolve with the administration, not remain fixed out of habit.

Signals that require updates

Not every disagreement requires a formal intervention. But some signals indicate that the co-trustee arrangement needs to be updated, tightened, or escalated.

Watch for these warning signs:

• Repeated missed deadlines: tax returns, notices, insurance renewals, or account transfers are delayed because the trustees cannot coordinate. Tax-related delays can create avoidable expense, so it is worth reviewing Trustee Tax Filing Guide: Key Returns, Deadlines, and When to Hire a CPA.
• One trustee withholds records: bank statements, invoices, correspondence, and transaction support are not shared promptly.
• Beneficiaries receive conflicting explanations: one trustee promises a distribution while the other says administration is incomplete.
• Important actions are taken unilaterally: contracts are signed, advisors hired, or funds moved without proper co-trustee approval.
• Decision-making slows to a standstill: the trust is effectively frozen because every issue becomes a fight.
• The dispute shifts from substance to motive: discussion focuses on personality, fairness, or family history rather than the trust’s terms and the beneficiaries’ interests.
• There are signs of self-dealing or divided loyalty: especially where a trustee is also a beneficiary or has some personal stake in a trust asset. See Can a Trustee Be a Beneficiary? Rules, Conflicts, and Best Practices.
• Notice obligations are being ignored: failure to provide required communications can increase tension and legal risk. See What Notices Must a Trustee Send to Beneficiaries?.

When these signals appear, do not rely on informal assumptions such as “this will calm down later” or “the other trustee means well.” A co-trustee dispute that affects administration should be treated as a compliance and risk issue. That does not mean filing in court immediately. It does mean moving from casual conversation to a structured response.

A practical structured response often includes:

1. reviewing the trust language and applicable state law
2. listing the disputed decisions and what is blocking them
3. identifying which issues are urgent and which can wait
4. gathering records into a common file
5. setting a written meeting agenda
6. bringing in a neutral attorney, CPA, appraiser, or mediator if needed

The goal is to convert the dispute from a vague conflict into a list of decisions, documents, deadlines, and remedies.

Common issues

The most useful way to think about co-trustee problems is by matching each issue to the most proportionate solution.

Deadlock over asset sales or investments

This is one of the most common forms of co-trustee deadlock. One trustee wants to sell a concentrated asset or family home; the other wants to hold it. The best response is usually to gather objective information before debating outcomes. That may include an appraisal, broker opinion, repair estimate, tax analysis, or investment review. Once the factual record improves, some deadlocks become manageable.

If the trust requires joint action and the trustees remain stuck, mediation may help. If the trust permits one trustee to act with delegated authority in a defined area, document that arrangement carefully. If neither option works and delay harms the trust, court instruction may be appropriate.

One co-trustee does all the work

Unequal participation is common, especially where one trustee lives nearby, understands finances, or has more time. The problem is not merely unfairness. It can also create liability confusion. The active trustee may assume all risk while the passive trustee still retains legal authority.

Start by separating inconvenience from incapacity. Is the inactive trustee temporarily overwhelmed, or consistently unwilling to perform? If the issue is manageable, consider dividing tasks by written agreement, with deadlines and reporting requirements. If the issue is chronic, resignation or removal may be the cleaner path. For step-by-step guidance, see Trustee Resignation Guide: Steps, Notice Requirements, and Handover Checklist.

Disputes over distributions

Co-trustees often disagree about whether a beneficiary should receive money now, later, or at all. These disputes are especially sensitive when the standard is discretionary, such as health, education, maintenance, or support. A disciplined process helps: review the trust standard, collect the beneficiary’s request and supporting documents, compare treatment of similarly situated beneficiaries, and create a written decision record.

A trustee should be able to explain not only the decision but the reasoning. That protects the trustees whether they approve or deny the request.

Poor communication with beneficiaries

Beneficiaries do not need a running commentary on every internal disagreement, but they should not be left in the dark when delays affect administration. Co-trustees should agree on who communicates externally, what updates will be provided, and when formal notices are required. Mixed messages from trustees often trigger avoidable beneficiary complaints and can pull the dispute into a larger trust contest.

Suspected fiduciary duty breach

If the issue is not simple disagreement but suspected misconduct, the analysis changes. Examples may include misuse of funds, concealment of records, favoritism, refusal to follow the trust terms, or acting for personal benefit at the trust’s expense. In that setting, the non-breaching co-trustee may need independent legal advice quickly. The right next step could be a demand for records, a freeze on further transactions, mediation, court instructions, or a petition for removal.

If removal becomes necessary, see How to Remove a Trustee: Grounds, Evidence, and Court Process. The key is to build the record carefully. Courts generally respond better to specific conduct, documented harm, and failed attempts at correction than to broad claims that the trustees simply “do not get along.”

How to remove a co-trustee without making things worse

Many readers search for how to remove a co-trustee because the relationship feels impossible. But removal is a serious remedy, not just a frustration release valve. Before pursuing it, ask:

• Is the issue bad judgment, lack of availability, conflict of interest, or actual breach?
• Does the trust document provide a non-court removal mechanism?
• Is resignation realistic if a face-saving exit is offered?
• Would mediation preserve value better than litigation?
• What evidence supports the requested change?

Sometimes the most practical solution is not immediate removal but narrowing decision points, appointing a neutral professional, or obtaining court instructions on a specific issue. Other times, administration cannot continue safely without replacing the trustee.

When to revisit

Co-trustee arrangements should be revisited at predictable intervals and at practical trigger points. A good rule is to review the governance process at least quarterly during active administration and immediately before any major action.

Revisit this topic when:

• a death has recently occurred and trustees are just beginning administration
• the trust holds a house, business interest, or concentrated investment
• a beneficiary requests a significant discretionary distribution
• one trustee becomes unavailable, ill, unresponsive, or openly hostile
• tax filings or accountings are overdue
• beneficiaries begin challenging decisions or asking for more information
• the trustees are considering resignation, replacement, or court intervention
• search intent shifts from “how do co-trustees work together?” to “how do I stop harm now?”

For a practical next-step checklist, use the following sequence:

1. Pull the governing documents. Read the trust language on co-trustee authority, removal, resignation, and notice.
2. Define the problem precisely. Is this deadlock, delay, poor records, unauthorized action, or possible breach?
3. Create a written issue list. Include pending decisions, deadlines, and what each trustee believes should happen.
4. Organize the file. Gather statements, correspondence, tax documents, appraisals, and prior beneficiary communications.
5. Set a decision meeting. Use an agenda and circulate it in advance.
6. Bring in neutral expertise if needed. An attorney, CPA, appraiser, or mediator can narrow factual disputes.
7. Document the outcome. Record approvals, objections, and next steps.
8. Escalate only as necessary. If informal solutions fail, consider resignation, removal, or court instructions based on the facts.

The most useful habit is not waiting for a crisis. Co-trustee problems become expensive when months of frustration pass without a system. A recurring review cycle, clear records, and disciplined communication can prevent many disputes from becoming allegations of fiduciary duty breach. And when a dispute truly cannot be fixed, those same habits make it easier to choose the right remedy with less confusion and less risk.
