Selling for Someone Who Can't Sign for Themselves: Estates, POA, Guardianship, Bankruptcy, and Power of Sale (Ontario)

The common thread across estates, powers of attorney, guardianship, bankruptcy, and power of sale is a single question: who has the legal authority to sign this listing and this Agreement of Purchase and Sale, and what proves it? The registered owner is often unable to sign (deceased, incapable) or has lost control of the sale (bankrupt, in default). If you take a listing from the wrong person, the deal can collapse on closing when the lawyer cannot deliver good title — or you can be found to have breached your TRESA duties. Your job is not to determine authority yourself; it is to spot which category you're in, ask for the authority document, and insist the lawyer confirm it before you list.

Estates: Selling After the Owner Has Died

When a sole registered owner dies, the deceased cannot sell and neither can the family by default. Authority flows through the estate.

Estate listing practicalities

Powers of Attorney (Living Owner Who Can't or Won't Sign)

A Power of Attorney for Property lets an attorney act for a living grantor. Governed by the Substitute Decisions Act, 1992 (SDA).

Capacity and Guardianship (No Valid POA)

If a living owner is mentally incapable and there is no valid Continuing POA, no one can simply step in.

Bankruptcy and Receivership

When an owner is bankrupt, control of their property shifts by operation of federal law under the Bankruptcy and Insolvency Act (BIA).

Power of Sale and Mortgagee Sales (Mortgages Act)

When a borrower defaults, a lender (mortgagee) may sell the property to recover the debt. In Ontario this is usually power of sale under the Mortgages Act (not judicial "foreclosure," which is slower and rarer here). You may be listing for the lender, or representing a buyer of a power-of-sale property.

Authority-to-Sign Checklist (Who Can Actually List and Sell?)

Before taking any listing where the person in front of you is not the sole, living, competent registered owner, confirm the category and the document:

Situation Who signs Authority document to get
Owner deceased, has will Estate trustee named in will Will + Certificate of Appointment of Estate Trustee (probate); Small Estate Certificate if ≤$150k
Owner deceased, no will Court-appointed estate trustee Certificate of Appointment of Estate Trustee Without a Will
Owner alive but incapable, has POA Attorney for property Continuing Power of Attorney for Property + declaration it's unrevoked
Owner alive, incapable, no POA Guardian of property Court guardianship order / SDA management plan, or PGT statutory guardianship
Owner bankrupt Licensed Insolvency Trustee BIA Certificate of Appointment / trustee authority
Property in receivership Receiver Court order appointing receiver
Borrower in default Mortgagee (lender) Mortgage + Notice of Sale; timing per Mortgages Act s. 42
Joint tenant died Surviving joint tenant Death certificate + lawyer's survivorship confirmation

In every case: get the document, confirm the exact signing capacity/wording, and have the client's lawyer verify authority before you list. Never rely on "I have power of attorney" or "I'm the executor" spoken without paper.

Reference text, not legal advice. Authority to list and sell on behalf of an estate, an incapable owner, a bankrupt, a receivership, or under a mortgage power of sale is governed by Ontario and federal statutes and by court/probate processes that change and that turn on the specific documents. Confirm every authority-to-sign question, APS schedule, and closing requirement with the client's licensed Ontario real estate lawyer, and verify current statutes at ontario.ca/laws (e-Laws).
