You will have to contact DVLA to obtain the correct forms (there are always forms !) to register a vehicle.

Look in your phone book under 'DRIVING'

There will be a half page advert listing the DVLA services and the address and phone number of your DVLA Local Office.  That is probably the best place to start.

The Driving Agency website is www.motoring.gov.uk  - I'll let you find out whether it helps or not .
