Hi --- If the car is currently taxed or has just expired, you need to take the following documents to your local DVLA licensing office.
V70 exchange of licence form, that changes the taxation class from disabled, to PLG class.( I think they have blank forms ?)
Current or expired tax disc.
V5C Vehicle registration document (log book) Or the transfer of ownership slip that you would have been temporarily given.
Valid insurance certificate, or cover note (not a photocopy)
Valid MOT certificate.
And your fee £ ?
