What Happens When One Co-Executor Dies During Estate Administration in Ontario

Administering an estate can take months, sometimes longer, especially where assets are complex or a property needs to be sold. If two or more people were named as co-executors and one of them dies before the job is finished, the question of what happens next depends on a few key details — and it is not always as simple as the survivor just carrying on.

Getting this wrong can leave decisions made afterward open to challenge, so it's worth understanding the general rule and its exceptions.

The General Rule: Survivorship Among Co-Executors

Ontario law generally treats the role of estate trustee, when held jointly by two or more people, as passing to the survivor(s) if one dies before the administration is complete — similar to how a joint asset passes to a surviving joint owner. In most cases, a surviving co-executor can continue to administer the estate without needing to go back to court for a fresh appointment, provided:

• The original Certificate of Appointment named them jointly, and
• The will (if there is one) does not say something different, and
• At least one of the originally appointed trustees is still alive and willing to act.

This is sometimes described as the surviving trustee "carrying on" the administration under the existing appointment, rather than needing an entirely new one.

When It Is Not So Simple

The general survivorship rule has real limits, and several situations call for a closer look before assuming the survivor can simply continue unaided:

All co-executors have died

If every originally appointed estate trustee has died before the estate is fully administered, there is no automatic survivor to carry on, and a new application will generally be needed to have someone else appointed to complete the administration.

The will specifies something different

Some wills include specific instructions about what happens if a named executor dies during administration — for example, naming a particular alternate to step in rather than relying on the surviving co-executor alone. Where the will addresses this directly, its terms generally govern.

Concerns about the surviving trustee acting alone

If beneficiaries have concerns about the surviving trustee's ability or willingness to properly complete the administration alone, this can become a point of dispute requiring court involvement, even where the general survivorship rule would otherwise apply.

The deceased co-executor held unfinished, personal responsibilities

Some tasks may have been informally divided between co-executors during the administration. Their completion does not depend on a separate legal appointment, but practically, the surviving trustee will need to pick up whatever was left unfinished, which can mean real delay while records and account access are sorted out.

Steps a Surviving Co-Executor Should Generally Take

1. Confirm the terms of the original appointment and the will to check whether either addresses what happens if a co-executor dies.
2. Gather records from the deceased co-executor's estate relating to any estate business they were handling, since those records remain relevant to the ongoing administration.
3. Notify relevant institutions — banks, the land registry, investment firms — of the change, since some may require updated documentation before continuing to deal with the surviving trustee alone.
4. Get legal advice on whether a court application is needed in your specific case, particularly if the will is silent, if all trustees have died, or if any beneficiary raises concerns.
5. Continue keeping detailed accounts, since the surviving trustee remains accountable for the administration, including for records or handovers that may be incomplete due to the co-executor's death.

Why This Differs From a Regular Executor Simply Dying Before Acting

It matters whether the deceased co-executor had already begun acting, or died before the estate was ever opened. If a named executor dies before a Certificate of Appointment was issued at all, that is a different situation — the surviving named executor (or an alternate) generally applies for the original appointment in the normal way, rather than dealing with a mid-administration survivorship question.
