When a co-executor is not cooperating, you have three moves in order: document everything, try to resolve it informally through a written demand or mediation, and if that fails, petition the probate court to compel the co-executor to act or to remove them entirely. Sitting on the problem is the one option you don’t have, because a cooperating co-executor who knows about the other’s misconduct and does nothing can share personal liability for the resulting harm.
Why Doing Nothing Is Not an Option
Courts in most states treat co-executors as jointly responsible for estate administration. If your co-executor is wasting assets, missing tax deadlines, or refusing to sign documents, and you know about it but take no steps to address it, a court can hold you personally liable for the losses. You had the same fiduciary duty they did, and part of that duty was to protect the estate from harm, including harm your co-executor caused.
Personal liability here means a court can order you to reimburse the estate out of your own pocket. Beneficiaries who lose money because of delayed administration or mismanaged assets have every reason to pursue whichever executor has resources to pay. The cooperating co-executor who documented the problem and took action is in a far better position than the one who hoped it would sort itself out.
Every executor owes the estate a fiduciary duty, which includes loyalty (no self-dealing), impartiality among beneficiaries, and competent care of the assets. Co-executors also owe each other a duty to communicate and act jointly. Neither one has authority to run the estate as a solo operation, and decisions about selling property, paying creditors, and distributing assets generally require both to agree. When one goes silent or starts acting unilaterally, that is a breach, not just a personality problem.
What Non-Cooperation Looks Like
Non-cooperation isn’t always obvious. Sometimes it’s passive, like an executor who won’t return calls or lets deadlines pass. Other times it’s active obstruction. Common forms include:
- Refusing to sign documents. Property deeds, tax returns, and bank account paperwork typically require both co-executors’ signatures, and one holdout can freeze the entire estate.
- Going silent. Ignoring calls, emails, and certified letters from you or from beneficiaries.
- Withholding information. Keeping asset inventories, bank statements, or creditor lists to themselves.
- Acting alone. Selling property, paying bills, or making distributions without your knowledge or consent.
Any of these can support court intervention. First, though, you need a record showing you tried to fix it yourself.
Do You Even Need the Other Co-Executor’s Agreement?
Before heading to court, find out whether your state actually requires both co-executors to agree on every decision. The answer varies. In states that follow the Uniform Probate Code, where one co-executor is unavailable or unable to act, the remaining co-executor can often exercise full authority. Roughly 18 states have adopted substantial portions of the UPC, and their rules tend to be more flexible about independent action.
Other states require co-executors to act unanimously, which means a single uncooperative co-executor can paralyze administration. Some states fall in between, allowing majority action when there are three or more co-executors but requiring unanimity when there are only two. Check your state’s probate code or ask a local estate attorney, because if your state allows independent action, you may be able to move the estate forward without a court fight.
Informal Steps Before Filing Anything
Courts expect a genuine effort to resolve the conflict before you file a petition. Those efforts also build the paper trail you’ll need if you end up there anyway.
Send a Written Demand
Start with a formal written letter to the non-cooperating co-executor. Spell out exactly what the estate needs them to do, such as signing a specific deed or producing bank statements, and set a reasonable deadline, usually 14 to 30 days. Send it by certified mail with return receipt requested so you have proof of delivery. Keep a copy of everything. The letter gives fair warning and later serves as evidence that you exhausted informal remedies.
Propose Mediation
If the written demand doesn’t produce a response, propose mediation. A neutral mediator can sometimes break through personal conflicts that have nothing to do with the estate itself. Family dynamics, old grudges, disagreements about what the deceased “really wanted”: these are the issues that derail co-executor relationships, and a skilled mediator can separate the emotional dispute from the administrative one. Mediation is faster and far less expensive than litigation, and many probate judges will ask whether you attempted it before entertaining a removal petition.
Have an Attorney Send a Demand Letter
A formal demand letter from an estate attorney signals that the situation has moved beyond a family disagreement. The letter typically lists the co-executor’s specific duties, identifies the breaches, and warns of the consequences of continued non-cooperation, including personal liability and removal. For some uncooperative co-executors, this is the wake-up call that finally gets them to act.
Asking the Probate Court to Step In
When informal efforts fail, the probate court has broad authority to resolve co-executor disputes. You’ll generally choose between two types of petitions depending on the severity of the problem.
Petition to Compel Action
A petition to compel asks the court to order the non-cooperating co-executor to perform a specific duty: sign a particular deed, produce financial records, or file a required tax return. This works best for single-issue bottlenecks. If the co-executor is generally cooperative but refuses to sign off on one transaction, a court order directing them to act can resolve the dispute without removing anyone. If they then ignore the order, that disobedience itself becomes grounds for removal and potential contempt sanctions.
Petition for Removal
A removal petition is the more serious remedy, and courts don’t grant it lightly. Judges give real weight to the deceased’s choice of executor, so you’ll need more than a personality clash. Courts generally consider removal warranted when an executor has misused or mismanaged estate funds, has a conflict of interest affecting their ability to act impartially, deliberately refuses to fulfill their duties or causes unreasonable delay, fails to comply with court orders or the directives in the will, or puts their own interests ahead of the estate’s.
A pattern of non-cooperation that harms beneficiaries falls squarely within these grounds. The key word is “harm.” A co-executor who is slow to answer emails but eventually gets things done is annoying. A co-executor whose refusal to act is causing the estate to miss tax deadlines, lose property value, or delay distributions for months is causing real damage, and that is what moves a judge to act.
Building Your Case
For either petition, your evidence should include the will, the Letters Testamentary that appointed both co-executors, and every piece of written communication demanding cooperation. Compile certified mail receipts, unanswered emails, text messages, and records of any unilateral transactions the other co-executor made without your consent. Bank statements showing unauthorized withdrawals or transfers are particularly compelling. Show a pattern, not one bad day.
What the Process Looks Like
You file the petition with the probate court that has jurisdiction over the estate. The non-cooperating co-executor is then formally served with the petition and a notice to appear. The court schedules a hearing where both sides present evidence. Some courts appoint a guardian ad litem or special master to investigate before ruling. Depending on the court’s calendar and the complexity of the dispute, the process can take anywhere from a few weeks to several months.
What Happens After Removal
Once the court removes a co-executor, the remaining co-executor typically continues administering the estate alone with full authority. If the will names a successor, the court may appoint that person. If it doesn’t, and the court believes a sole executor is insufficient given the estate’s complexity, it can appoint a professional administrator or a bank trust department.
The removed co-executor can also face financial consequences. If their breach of fiduciary duty caused losses, the court can surcharge them, meaning it orders them to personally reimburse the estate. The court can also void transactions the removed executor made improperly, such as below-market asset sales or unauthorized distributions.
Voluntary Resignation as an Alternative
Sometimes the uncooperative co-executor isn’t acting out of malice. They’re overwhelmed, uninterested, or didn’t realize what they were agreeing to when they accepted the appointment. In that case, the simplest resolution is a voluntary resignation. Most states allow an executor to petition the probate court to be relieved of their duties, and the court generally grants the request as long as the resignation won’t leave the estate without anyone to administer it. If you suspect your co-executor would step down if asked directly, have that conversation before you spend time and money on a contested removal.
What It Costs to Go to Court
Contested probate matters aren’t cheap. Court filing fees for executor-related petitions typically run a few hundred dollars, though the exact amount varies by jurisdiction. Attorney fees are the bigger concern: probate litigation attorneys commonly charge between $250 and $500 per hour, and a contested removal can take significant attorney time for petition drafting, discovery, and hearings.
Who pays depends on the circumstances. When a co-executor files a petition to protect the estate from genuine harm, the court often allows those legal fees to be paid from estate funds, because the litigation benefits all beneficiaries. If the court views the petition as frivolous or motivated by personal animosity, you could be stuck paying your own costs. An estate attorney can help you evaluate whether your situation justifies the expense and the likelihood that the estate will reimburse you.
Mediation typically costs far less. Professional mediators charge hourly rates that, while not trivial, are a fraction of what a full court proceeding runs. Even an unsuccessful mediation attempt strengthens your position if you later need to show the court you tried everything first.
