What you're referring to is a transfer of ownership. If your son is of age of majority (19 or 18 depending on province) or older then you could go to the nearest Koodo kiosk and explain you're wanting to do a transfer of ownership, and be sure to have the following items as they will do a credit check for your son. Also when doing a transfer of ownership it costs $25 to do so.
Hi Daniel...he is the owner but I put my payment info in to pay his bill. I am the account manager in Koodo terms. I just can't seen to take off my VISA as it then wants chequing account info. I just want him to take his bill...he is 19.
