I guess Steve is correct, however, I live in Spain, where the only ‘person’ who can certify a copy as authentic is a person from the department where the original was issued, i.e. passport office/consulate in the case of a passport, DVLA for a D/L or a log book, etc, as only the place which issues the original can be certain that the original, presented to them (with a copy) is in fact a valid document and not a forgery.

Thus in Spain, a solicitor, notary, judge, police officer etc. cannot certify a copy. The same should apply everywhere. (In my former job I saw many forged documents which would have fooled almost anybody, certainly your average solicitor)
