Reviewed September 4, 2026. These articles provide general planning information. The contract, title records, property evidence, professional advice and applicable authority control each transaction.

When someone is helping an owner sell a home, goodwill and family relationships are not enough to establish signing authority. The document and the law control.

The cleanest process starts with legal review before the listing paperwork, photography or offer decisions begin.

Confirm what the document actually permits

A power of attorney for property can authorize another person to make specified financial decisions, which may include maintaining or selling a home. A power of attorney for personal care does not provide property authority.

The document controls. Ontario says an attorney for property may generally act immediately unless the power says otherwise; a continuing power may remain effective during incapacity.

Appointment as attorney does not make that person the owner. A spouse, child or other relative has no automatic signing authority merely because of the relationship.

Put the lawyer’s instructions ahead of the listing process

Before the property is offered for sale, the lawyer should review:

  • the original or acceptable power-of-attorney document;
  • title and the registered owners;
  • the identity of the owner and attorney;
  • conditions, restrictions or activation language;
  • execution and land-registration requirements; and
  • whether the authority remains valid for this transaction.

The real estate representative can coordinate the sale after legal authority and signing instructions are confirmed. The agent does not determine capacity, validate the document or interpret the attorney’s fiduciary duties.

Keep a disciplined record

Offer instructions, property expenses, decisions and the handling of funds may need careful records. The estate or real-estate process should follow the lawyer’s direction and the document—not a generic public checklist.

The attorney is acting under authority, not taking ownership. That distinction should remain clear in pricing, disclosure, offer review and closing communication.

A power of attorney ends at death. If the owner dies before closing, the lawyer must direct the next steps under estate authority; nobody should assume the existing signing process simply continues.
