How Multiple Executors Apply for One Certificate of Appointment in Ontario

Naming more than one executor feels like a natural way to share responsibility, or to make sure no single sibling is left carrying an estate alone. It works well in many families — but it also raises a practical question when the time actually comes to apply for probate: do co-executors each apply separately, or is there one application for all of them?

In Ontario, a will naming multiple executors generally results in a single Certificate of Appointment of Estate Trustee that names the executors who are actually going to act — but getting there depends on whether everyone named is willing, available, and in agreement.

Scenario 1: All Named Executors Are Willing to Act

Where every executor named in the will wants to act, they typically apply together for one Certificate of Appointment naming all of them jointly as estate trustees. From that point forward, they generally act as co-trustees, which usually means major decisions — like selling estate property or making significant distributions — require agreement among them, unless the will itself sets out a different arrangement.

This is often the most straightforward path procedurally, but it also means co-executors need to be prepared to coordinate closely with each other for the life of the estate administration.

Scenario 2: One Named Executor Doesn't Want the Job

It is common for a will to name two or three people, only for one of them to decide, once the time comes, that they do not want to take on the responsibility. An executor in this position can generally formally renounce their role, stepping aside so that the remaining named executor or executors can apply for the Certificate without them.

Renouncing is not the same as simply ignoring the role — it is a formal step, and once someone has started acting as an executor (for example, by dealing with estate assets), renouncing may no longer be straightforward. Anyone considering this route should raise it early, before taking any steps as executor.

Scenario 3: A Named Executor Is Unreachable or Unresponsive

Sometimes a named executor cannot be located, or is unwilling to formally renounce but also isn't participating. In this situation, the executors who are moving forward cannot simply leave that person out, because the court rules require a renunciation from every living named executor who has not joined the application. The usual route is a court order, such as one requiring that person to accept or refuse the appointment.

A court order lets the estate move forward without being permanently held up by one person's absence.

Putting Together a Joint Application

1. Confirm who is actually applying. Identify which named executors intend to act, and address renunciation early for anyone who does not.
2. Agree on practical coordination in advance. Decide how co-executors will communicate, sign documents, and make joint decisions before the estate's day-to-day administration begins.
3. Prepare the application together. The court application generally requires consistent information from all applying executors, including the required affidavits, along with a renunciation from any named executor who is not applying.
4. Apply for the single Certificate of Appointment. Once issued, it names the acting estate trustees, who then generally need to act jointly for significant estate matters going forward.
5. Set up one estate bank account for joint signing. Coordinating access and signing authority early avoids delays once funds need to move.
