I am married but my spouse is not on title. Does he/she still need to sign closing documents?

If the property is a matrimonial home, then your spouse will need to execute closing documents as a “consenting spouse”. When it comes to selling or mortgaging a property in Ontario, the consent and signature of a non-titled spouse is required in order to complete the transaction. This is because matrimonial property rights apply notwithstanding that the spouse is on title or not.
