What is a spousal consent or acknowledgment form and why does a lawyer ask for one during a real estate closing?

A spousal consent or acknowledgment form is a document real estate lawyers routinely use to confirm whether a property being sold, mortgaged, or otherwise dealt with is a matrimonial home under Ontario's Family Law Act, and if so, to obtain the other spouse's formal agreement to the transaction. Because the Act requires both spouses' consent before a matrimonial home is disposed of or encumbered, regardless of whose name is on title, lawyers use this form to document that requirement has been satisfied, or to confirm the property genuinely isn't a matrimonial home in the first place.

This isn't just paperwork for its own sake — it protects everyone involved. It protects the non-titled spouse's statutory rights by making sure their agreement is properly obtained and recorded, it protects the titled spouse and buyer by creating a clear record that the transaction complied with the law, and it protects a purchaser or lender relying in good faith on a statutory declaration about marital status. Skipping this step, or treating it as unnecessary because "it's not really our home" or similar assumptions, can expose a sale to a later challenge. Anyone involved in a residential real estate transaction should expect their lawyer to raise this and answer honestly about marital status and how the property is actually used.
