Booking an Appointment:

While it is not mandatory to book an appointment, it is strongly recommended so that we can ensure someone is available to assist you. We cannot guarantee availability of a commissioner without an appointment booked in advance. 

ID & Documents: The individual taking the oath and signing the document must present one original piece of government issued photo identification (Ie. a valid driver's licence or valid passport which includes a current address). Please complete the document(s) to be commissioned beforehand, but do not sign the document in advance - the Commissioner must witness your signature.
