Because they become both the legal owner and the registered keeper.

I'm sorry that you're finding this boring, but if you're going to suggest fraud on a public forum you should at least be prepared to defend your advice.

BoostMeCoupeUp is correct, although it may say on an actual V5 that the registered keeper may not be the legal owner in the eyes of an insurance company the registered keeper is the owner.

All of that and still if the log book doesn't represent ownership what does?

Cheers Jase this is getting way over complicated it is pretty simple... If you look into every eventuality in insurance eg tyres under a certain amount of tread etc etc then theres always ways a company can get out of paying.

You CAN use your driving other cars extention in this mannor if you know what your doing and are check policy wording. IM OUT

The V5 (it's not called a log bog and hasn't been for many years) shows the keeper of the vehicle. It states (in section c5) that it does not indicate the owner of the vehicle. There is no single document that indicates ownership.

Look at a simple case - a vehicle purchased under a hire purchase scheme. The keeper of the vehicle will be named on the V5, but it is the HP company which has ownership of the vehicle.

The vast majority of the time it is convenient for an insurer to assume that the owner and registered keeper are the same entity, but if it suits them to do so they are fully entitled to treat them as different.

Whichever way you cut this what you're proposing is insurance fraud, and that increases the cost of insurance for everybody, which brings us full circle - your advice is wrong, please don't post it here again.

I'll just step into the bun fight to give my tuppence.

On occasion, I have used my own DOC cover to drive other people's cars that were already insured.

This was for occasional 1 off use. I have never done it in a car that was expensive, that would be crazy (as I know I only have 3rd party cover).

The part which scares me about this option being disccussed by boostmycoupeup is that the car is only insured when someone is driving it.

What would happen if your car set on fire one night and burnt down your house?

What would happen if you parked on a hill and the car rolled down a hill and killed someone?

Personally, I thing you would be crazy to risk the possible consequences just for that sake of saving a few £s. If you own two cars insure two cars.

Personally I'd have thought that it would be more annoying that the car won't show up on the MID database, which means that it will trigger ANPR systems, so you'll probably get to spend a lot of time talking to traffic policemen
