Do You Need Probate to Sell a House You Inherited in Ontario?
Short answer: yes, in almost every case. If the deceased owned the home alone or as a tenant-in-common, you need a Certificate of Appointment of Estate Trustee (Ontario’s current term for probate) before a buyer’s lawyer will let the sale close. There are two narrow exceptions. Here is how to tell which situation you’re in, and what the process actually costs and takes.
Why probate is almost always required to sell
Ontario’s Superior Court of Justice — the body that issues the certificate — states it directly: if “the deceased’s real property must be sold,” a Certificate of Appointment of Estate Trustee (or a Small Estate Certificate for smaller estates) “should be obtained before anyone enters into an Agreement of Purchase and Sale.” Without it, you have no legal authority to sign on the estate’s behalf, and no title insurer will back the transaction. This isn’t a formality a lawyer can talk their way around — it’s how the land registry system verifies who has authority to deal with a deceased owner’s property under the Land Titles Act and Registry Act.
The two exceptions
Joint tenancy with right of survivorship. If the deceased owned the home jointly with someone else — most commonly a spouse — as joint tenants (not tenants-in-common), the property does not form part of the estate at all. Ownership passes automatically to the survivor by operation of law. The survivor’s lawyer files a Survivorship Application under section 123 of the Land Titles Act, with a death certificate, and can typically complete it in weeks rather than months. No probate, no Estate Administration Tax on that asset.
The First Dealings Exemption. This is a narrow, often-missed exception for older properties. If the home has the qualifier “Land Titles Conversion Qualified” on its parcel register, and it has not been dealt with (sold, mortgaged, or transferred) since the province converted it from the paper-based Registry system to Land Titles — generally meaning it was last transferred before the mid-1990s — the estate trustee may be able to transfer or sell it as the “first dealing” without probate. It only works if the will is never actually probated, since applying for a certificate pulls the property’s value back into the Estate Administration Tax calculation and defeats the exemption. This is worth having a lawyer check on the parcel register before you assume probate is unavoidable — but it applies to a shrinking number of properties.
Outside these two situations — sole ownership, tenancy-in-common, or no will at all — plan on probate.
What the process actually involves
For estates valued at $150,000 or less, you apply for a Small Estate Certificate; above that, a full Certificate of Appointment of Estate Trustee. Either way, the estate trustee files an application with the Superior Court of Justice in the county where the deceased lived, including the original will, proof of death, and forms detailing the value of the estate’s real and personal property. Beneficiaries must be served with the application before it’s filed. Ontario’s court service notes straightforward applications are typically processed within about 15 business days of filing — but that clock starts only once every form, affidavit, and signature is correctly in place, which is usually where the real delay happens.
What it costs: the Estate Administration Tax
The tax is paid as a deposit when you file the application, based on the estate’s value at death. As of 2026, Ontario charges nothing on the first $50,000 of estate value, then $15 for every $1,000 (1.5%) above that, rounded up to the nearest thousand. A home is valued at its fair market appraisal on the date of death — not what it eventually sells for — so getting that valuation right early matters for more than one reason.
Worked example: an estate worth $700,000 (home plus other assets, less the mortgage) pays $0 on the first $50,000, then $15/$1,000 on the remaining $650,000 — $9,750 in Estate Administration Tax. Real estate is included at its appraised value less encumbrances like a mortgage; funeral costs, legal fees, and unsecured debts are not deductible from the estate’s value for this calculation, which surprises a lot of executors.
Why you can’t skip it, even informally
Some executors ask whether they can just list the house and sort out probate before closing. In practice, no serious buyer’s lawyer will complete a closing without seeing the certificate registered, because it’s the document that proves the seller actually has authority to convey title. Trying to sell first and probate later just adds a stalled closing to an already stressful process — and if you distribute or act before the estate’s debts are confirmed, you risk personal liability for any shortfall.
FAQ
Does every estate need probate? No — only when the asset (like real estate held solely or as tenants-in-common) requires proof of authority to transfer. Assets with named beneficiaries, or jointly held with survivorship, generally bypass it.
How is Estate Administration Tax different from probate itself? Probate is the court process; the tax is what you pay to the Ministry of Finance, via the court, to obtain the certificate. You owe it whether or not the sale ultimately closes at the appraised value.
Can I apply for probate and list the house at the same time? Yes — many executors do list concurrently, as long as the Agreement of Purchase and Sale isn’t finalized until the certificate is in hand. Coordinating the estate administration and the sale together, rather than sequentially, is usually what keeps the timeline from stalling.
What if there’s no will? Ontario’s intestacy rules under the Succession Law Reform Act determine who has priority to apply, and you’ll need a Certificate of Appointment of Estate Trustee Without a Will — the same probate requirement applies to selling the home.
