Co-Executors Who Disagree About Selling: What Happens

Published 12 November 2026 · By Jatin Dua, Broker of Record, RE/MAX Quantum Realty

A will names three siblings as co-estate trustees. The house is the main asset. Two want to sell it now. One wants to keep it, or wants a different price, or will not return calls.

Families expect this to be resolved by a vote. It is not. Here is how Ontario actually handles it, and what the realistic paths out are.

The rule that surprises everyone: two against one does not win

Unless the will says otherwise, co-trustees in Ontario are generally expected to act unanimously. Every trustee must agree before a decision is carried out.

The practical consequence is blunt: one dissenting trustee can block a decision the others all support. A majority generally cannot outvote the rest.

This is why estate sales stall. It is not that the holdout has a stronger legal position — it is that the default rule requires agreement, and they are withholding it.

A will can change this. It can expressly permit majority decisions, or give one trustee a tie-breaking or final say on defined matters. Most wills drafted without much thought do neither. The first thing to do is read the will and find out which kind you have.

Why this bites hardest on real estate

A house cannot be half sold. Transferring it requires the estate trustees to act, and a purchaser’s lawyer will want to see that the people with authority have signed. A listing agreement signed by two of three trustees is not a safe foundation for a transaction, and an agreement of purchase and sale in the same position is worse — you may have committed the estate to a closing it cannot perform.

So the sequence matters. Resolve the authority question before you list, not after you have an accepted offer and a buyer with a moving truck booked.

The realistic paths out

1. Find out what the disagreement is actually about

This sounds soft and it resolves most of these. Deadlocks that look like disputes about selling are frequently disputes about something else:

• the holdout wants to buy the house themselves and cannot afford it at market, or is embarrassed to say so
• they believe the property is worth more than the appraisal says
• they live in it, and “selling” means “moving out”
• they feel steamrolled by siblings who organised themselves first
• there is a grievance from twenty years ago that has nothing to do with the house

Each of these has a different fix, and only one of them is legal. An independent appraisal from a qualified appraiser resolves the valuation argument. A buyout at an appraised value, financed properly, resolves the first. A clear timeline resolves the fourth.

2. Get an independent valuation and put it in front of everyone

A date-of-death appraisal is needed for the estate’s tax filings anyway. Get a second, current opinion of value if the disagreement is about price. Two professional opinions in writing is much harder to argue with than one sibling’s conviction, and it is far cheaper than any of the options below.

3. A buyout, done properly

If one beneficiary wants the house, that is often the best outcome for everyone — no commission, no staging, no showings. It needs to be done at a defensible value with independent evidence, with the trustees documenting that they considered the alternative of a market sale. Trustees owe duties to all the beneficiaries, and a below-market family sale that was not properly evidenced is a liability the trustees carry personally.

4. Apply to the court for directions

Where the deadlock is genuine and persistent, a trustee can bring an application asking the court to resolve the specific disputed decision. This is the designed remedy for exactly this situation. It costs money and takes time, but it produces an answer and it protects the trustees who follow it.

5. Seek removal or replacement of a trustee

Where one trustee is obstructing the administration, is unreachable, or is in a conflict of interest, an application can be brought to have them removed or replaced. Courts do not do this lightly — disagreement alone is not misconduct, and the bar is meaningfully high. But sustained conduct that paralyses an estate to the beneficiaries’ detriment is a different matter.

6. Renunciation

Worth knowing: a named trustee who has not yet begun to act can generally renounce. Sometimes the cleanest resolution is a trustee who did not want the job stepping aside, rather than a fight about removing them. Ask early, before anyone has taken steps that count as acting.

What to do this month if you are in it

• Read the will for a majority clause or a tie-breaker. This single question determines everything.
• Get one estates lawyer involved for the estate — and understand that if the trustees are in conflict with each other, they may each need their own advice.
• Do not list the property until authority is settled.
• Keep the house insured and heated. Vacant property is a different insurance product, and a burst pipe in an unoccupied house during a deadlock is how a dispute about $40,000 becomes a dispute about $140,000.
• Put the disagreement in writing, calmly. A trustee who disagrees should make that clear on the record — silent acquiescence carries consequences if a decision is later found to be improper.
• Keep the costs in view. Litigation between trustees is usually paid for, one way or another, out of the asset everyone is arguing about.

The honest summary

Unanimity is the default, so the holdout has real power and no amount of family consensus overrides it. The cheap resolutions are an independent valuation and a properly documented buyout. The expensive ones are an application for directions or for removal, and they work but they come out of the estate.

In my experience the estates that resolve well are the ones where somebody insisted on a professional valuation early, before positions hardened.

This is general information about how Ontario’s rules work, not legal advice. Estate trustees carry personal liability and the duties owed to beneficiaries are real. Get an estates lawyer before you act — and if the trustees are in conflict, get separate advice.
