There are two parallel processes for probate, depending on the estate’s value:    $150,000 or less, you can apply for probate using the simplified small estate court process    More than $150,000, you must apply for probate using the regular court process You do not need a probate lawyer to file for a probate application, however, they understand how to draft the probate application according to Ontario’s civil procedure rules. Incomplete information, wrong information, or the application improperly drafted will cause unnecessary delays. If probate is granted, you will be issued a Certificate of Appointment as Estate Trustee with a will. It’s worthwhile checking to see that no one else has started a probate application or been granted a certificate of appointment as estate trustee.
