Updated August 7, 2026. Quick answer: 🔴 there is no statute that says what to do when co-executors deadlock. We looked. The law does not name the problem — it routes you to removal for cause, which is a blunter and slower instrument than most families expect.
The gap, stated plainly
Deadlock is not a statutory category. Neither the Uniform Probate Code nor the non-UPC states we checked names it as its own ground for relief. What exists instead is the general removal power — and it is framed around the estate, not around the argument:
A person interested in the estate may petition for removal of a personal representative for cause at any time. Cause for removal exists when removal would be in the best interests of the estate.
⚠️ Read what that asks of you. Not “we disagree” but “removal is in the best interests of the estate.” A genuine disagreement between two reasonable executors may not meet it — and the petition is against a person, usually a sibling, by name.
Why unanimity produces this so often
In most states two co-executors must both agree on every act — the concurrence default. So a single refusal is not an obstacle to one decision; it is a stop on the entire administration. Bills, sales, distributions and filings all wait.
What actually works, in order of cost
- Read the will first. The concurrence rule applies “unless the will provides otherwise”. 🔴 A clause permitting either to act alone, or majority rule, may already solve it — and it is the first thing to check, not the last.
- Narrow the dispute to the act. Concurrence is required act by act. Agreement on the uncontested ninety percent lets the estate keep moving while one item is argued about.
- Ask the court for instructions rather than for removal. It is a smaller ask, it does not accuse anyone, and it produces an answer both must follow.
- Resignation. ⚠️ Frequently the cheapest real solution and the least discussed — a co-executor who does not want the job can step aside without anyone having to prove they were unfit.
- Removal for cause, last. It is adversarial, it is slow, and the standard is the estate’s interests rather than your frustration.
🔴 And the honest prevention note: almost every deadlock traces to a drafting choice made years earlier, when naming two children felt fairer than choosing one. One executor plus an alternate avoids all of this.
