is there a website to put someone's details in on then?

I know someone that probably lost his licence a while ago (he's not sure as he reckons he should have sent it off years ago but forgot)

I know his car isn't taxed, I very much doubt mot'd as well. But I think he still pays insurance on it not that its valid.

I just can't remember the reg, i'd have to do some digging as its been a while since I have had anything to do with him
