Ancillary Probate: Administering Foreign Property From an Ontario Estate

An Ontario estate trustee who has just obtained a Certificate of Appointment often assumes the hard part is over. Then it turns out the deceased also owned a villa, a cottage, or a plot of land in another country — and the Ontario certificate, on its own, isn't something that country's land registry or courts have any obligation to act on. This is where the term ancillary probate tends to come up.

It sounds technical, and in a sense it is: how it works, whether it's even needed, and what it costs depends entirely on the country where the property sits, not on Ontario law.

What "Ancillary" Means in This Context

Ancillary probate is a general term used in estate practice — not a defined Ontario statutory process — to describe a secondary, follow-on procedure carried out in the place where foreign property is located, alongside the main ("primary") estate administration in the deceased's home jurisdiction. For an Ontario resident, Ontario is the primary jurisdiction; the country where the property sits is where any ancillary step, if one is required, would happen.

Why an Ontario Certificate Might Not Be Enough on Its Own

Land, in particular, is generally governed by the law of wherever it physically sits. A foreign land registry or court applies its own rules for confirming who has authority to deal with property located there — it isn't obligated to simply defer to a Canadian court's paperwork. An Ontario Certificate of Appointment of Estate Trustee is a genuine, valid Canadian legal document, but whether (and how) another country chooses to recognize it is a question for that country's own law to answer, not Ontario's.

This same idea shows up even between Canadian provinces, where an Ontario grant doesn't automatically extend to real property in another province either — the international version of the problem is simply a bigger jump, involving an entirely separate legal system rather than a neighbouring one.

How the Two Processes Typically Interact

1. The Ontario estate trustee is appointed and administers the Ontario portion of the estate in the usual way, under Ontario's Estates Act and its Rules of Civil Procedure.
2. Where foreign real property exists, the trustee — usually working with a lawyer licensed in that country — determines whether a local step is required before the property can be transferred or sold.
3. If it is required, the Ontario grant is often used as supporting evidence of who the estate trustee is, though the specific role it plays in the foreign process is entirely up to that jurisdiction's own procedure.
4. The local process, where one applies, generally runs on its own timeline and its own requirements, largely independent of how quickly (or slowly) the Ontario side wraps up.
5. Once the local step is complete, the estate trustee can deal with the property according to the will (or Ontario's intestacy rules, where there's no will) and the estate's broader obligations.

Practical Steps for the Estate Trustee

• [ ] Identify every piece of foreign real property early in the administration, not partway through
• [ ] Confirm exactly how each property is titled — jointly held property with a right of survivorship may pass outside any probate-type process entirely, in Ontario or abroad
• [ ] Retain a lawyer licensed in the country where the property sits to confirm what, if anything, is actually required there
• [ ] Keep the Ontario estate's accounting clearly separated from any foreign-property costs and proceeds
• [ ] Get tax advice covering both the Canadian side and, where relevant, the other country's own tax treatment of the property
• [ ] Expect this step to run on its own timeline, separate from the rest of the Ontario estate

Why This Article Won't Give You a Cost or a Timeline

Costs and processing times for a foreign ancillary process depend entirely on the country, the type of property, and that jurisdiction's own legal system — none of which Ontario law has any say over. No responsible general article can put a number on it. The realistic way to get an answer is to ask a lawyer licensed in that specific country, with your Ontario lawyer coordinating the Canadian side of the file.
