Notes for Retention of existing Registration Marks
To continue with this process you will need documentary proof if you do not have any then the application will be refused as the DVLA are extremely unlikely to accept an application. In this situation you are advised to apply for an age related registration mark.
Acceptable documentary evidence is:
1) Old Green and Buff Log Books
2) Pre 1985 tax discs
3) Pre 1985 MoT certificates
4) Pre1985 Bills of Sale and/or copies of The Original Registration Records.
