Just a minor correction...its 12 hours in the final year
When you re-validate, you have to have an examiners signature, which means that theoretically he's meant to examine your logbook. Forgetting the legal stance, if you fake entries, you'll probably get away with it, there is no way the CAA could check entries, especially if your hours have been abroad. You do need an hour with a JAA instructor though, and I'd like to think that most instructors would not countersign your logbook if your flying is crap.
As FFF says, is it really worth faking entries [not suggesting you would, but in general]? If a person fakes entries and has an accident, no doubt the magnifiying glass will be brought out, and if any descrepancies are found ramifications could be very serious, like null and void insurance, even jail terms, assuming that the person hasn't already managed to kill themselves.
