I recently bought a motorcycle in my missus name (not legal married) to save time as I didn't have the required docs. I know have the letter from my Amphur and

want to change into my name. Do I need anything apart from Passport, local Amphur letter, Thai drivers license? Can it be done over the counter

at transport department? Am I going to be up for transfer fees, taxes etc?
