rickbartlett does it state you are insured to drive your mates cars 3rd party all the time though??? Im sure the specific wording on such a policy will limit it.

Besides the original posters mate is still committing insurance fraud as the car is his own not his dads and it is only registered in dads name to gain financial advantage via an insurance policy. Sure the DVLA would find an offence to charge him with. Hes knowingly falsly registered the vehicle rather than "forgot to update details"

Sure theres a number of offences hes committing if the police could be bothered to investigate
