The driver has no role in the process unless also the owner. You need to find out what the arrangements are for the lease company receiving PCNs. Some just pay them and off-charge, with, (needless to say), and "admin fee", while others submit reps against the PCN and give the name and address of the leasing party on the contravention date. The first PCN is then cancelled and the council send a second one to the named party.
