Naming Co-Executors in Your Will: Should You Include All Your Kids?

💡

In Ontario, naming all your children as joint Estate Trustees (co-executors) might seem fair, but it often causes severe administrative delays. By law, co-executors must act unanimously. It is generally far more efficient to name one primary Estate Trustee and list the others as alternates.

When drafting a Will, parents naturally want to avoid playing favourites. It is incredibly common for parents in Ontario to want to name all three or four of their children as co-executors, assuming this will keep the peace. However, estate administration is not about fairness; it is about efficiency. Managing an estate involves liquidating bank accounts, selling real estate, and filing final taxes with the Canada Revenue Agency (CRA).

Whether you live in Toronto, Mississauga, or Ottawa, the legal reality is that naming multiple co-executors can create a logistical nightmare. Under Ontario law, unless your Will explicitly says otherwise, Estate Trustees must make every single decision unanimously. If your children disagree on when to sell the family home, or if one child lives out of the province, the entire probate process can grind to a halt. In this guide, we will walk you through the step-by-step process of structuring your executor appointments to protect your family’s wealth and maintain harmony. 📊

Step-by-Step Process in Ontario

Choosing an Estate Trustee is the most important decision in your estate plan. To avoid future family battles at the Superior Court of Justice, follow this practical approach to structuring your Will.

Step 1: Understand the Rule of Unanimity

First, you must understand that if you name three children as co-executors, all three must sign every document. They must all visit the bank together to open the estate account, and all three must sign the listing agreement with a real estate agent. If one child is busy, uncooperative, or grieving deeply, nothing gets done. Knowing this rule helps you realize why a single executor is often better. 📚

Step 2: Assess Their Geographic Locations

Consider where your children live. If one child lives in London, Ontario, and the other lives in the United States, managing a joint estate will be exhausting. Furthermore, naming a non-resident of Canada as an Estate Trustee can trigger massive tax complications and require them to post a costly probate bond. Always prioritize the child who lives locally.

Step 3: Choose a Primary and Alternates

The most legally sound strategy is to choose one capable, organized child to act as the primary Estate Trustee. You then name your other children as first and second alternates in case the primary is unwilling or unable to act. To soften the emotional blow, you can write a private “Letter of Wishes” explaining that you chose the primary executor simply for administrative ease, not out of favouritism. ✍️

Step 4: Draft a Majority Rule Clause (If You Must)

If you absolutely insist on naming three children to act jointly, you must instruct your family lawyer to include a “Majority Rule” clause. This legal clause specifically overrides the default rule of unanimity, stating that if the three children disagree, the decision of any two of them will legally bind the estate. This prevents a single stubborn child from holding the estate hostage.

Step 5: Include a Dispute Resolution Mechanism

For parents who anticipate friction, you can have your law firm draft a dispute resolution clause. This requires the co-executors to attend mandatory mediation before they are allowed to use estate funds to sue each other. Keeping disputes out of the public court system saves time, protects privacy, and preserves the inheritance. 🤝

How Much Does it Cost in Ontario?

Poorly structured executor appointments can cost an estate tens of thousands of dollars. Here is a look at standard legal costs and potential financial risks.

Service / RiskEstimated Cost in CAD (May 2026)Why is it necessary?
Drafting a Standard Will$500 to $1,500+A lawyer properly drafts the primary and alternate executor clauses.
Estate Trustee CompensationTypically up to 5% of estate valueCo-executors must split this fee; it is not 5% per person.
Probate Tax (Estate Admin Tax)Roughly 1.5% over $50,000Mandatory provincial tax to validate the Will at court.
Cost of Estate Litigation$20,000 to $100,000+The devastating cost if co-executors fight and end up in a trial.

Hiring a professional law firm to structure your Will correctly is a tiny investment compared to the devastating costs of family litigation. 💵

How Long Does the Process Take?

Meeting with an estate lawyer to draft and finalize your Will typically takes 2 to 4 weeks. However, the true timeline impact happens after you pass away. A smoothly run estate with one organized executor generally takes 12 to 18 months to fully settle. If you name multiple co-executors who argue over every detail, the estate administration can easily drag on for 3 to 5 years.

Frequently Asked Questions (FAQ)

Can an executor also be a beneficiary?

Yes. In Ontario, it is extremely common for a primary beneficiary (like your child) to also act as the Estate Trustee. However, an executor or their spouse cannot be a witness to the signing of the Will, or their inheritance may be voided.

What happens if one co-executor refuses to help?

If an appointed executor does not want the job, they can sign a formal “Renunciation” before the probate process begins. The remaining co-executors can then proceed without them. If they refuse to resign but also refuse to act, you may have to apply to the court to have them removed.

Can my children hire a trust company to do the work?

Yes. If your children are overwhelmed, they can hire a corporate trustee, an estate lawyer, or an accountant to perform the administrative heavy lifting. The professional’s fees are typically paid out of the executor compensation or directly from the estate.

Do co-executors get paid more money?

No. In Ontario, standard executor compensation is roughly 5% of the estate’s value. If you name three co-executors, they do not get 5% each (15% total); they must split the single 5% fee amongst themselves based on the amount of work each actually performed.

What if my children simply cannot agree on selling the house?

If the Will requires unanimity and the co-executors hit a complete deadlock, one of them will eventually have to hire an estate litigation lawyer to file an Application for Directions with the Superior Court of Justice, asking a judge to break the tie.
