When it comes to real estate in a will, it usually makes the most sense to probate it. MoneySense said, "You also ask if you must apply for a Certificate of Appointment of Estate Trustee with a will. This is a specific Ontario term. Ontario uses gender-neutral terms such as ‘estate trustee’ with a will or without a will." Including real estate in a will can be tricky business, so it's often best to meet with professionals and discuss the options when writing the will.
