There's probably more that you are not telling us in this question. If it's your car insurance, then no, the insurance company will send you a cancellation notice before cancelling your auto insurance. If you illegally have your car on someone else's policy, didn't pay them, and they removed your car from their policy then yes. The only thing is they never should have put your car on their policy but that is as much your fault as theirs. An individual has no requirement to notify you when they decide to make a change on their insurance policy.
Not legally. This would generally be classified as identity theft.
No, the insurance has to be on your car not someone elses.
That is fraud!
um... yeah if your on your parents insurance....... i think
If you owned it, you claim on your insurance.
yes you can but if you wreck and they have insurance their car will be ok but your screwed
You home owners liability insurance should cover it.
Trespasser is the term for this. This is illegal and you can be arrested for it. A police officer will not usually arrest someone the first time they are caught trespassing. But it is up to the police officer to arrest or not.
Registration, license plate number and title right?
Most insurance companies will not, they require you to have an "insurable interest" in the vehicle.
If you are not the administrator, executor, or an heir to the will your will not know and frankly it is not anyone elses business about the life insurance or financial matters of the estate.
That is something that you really have tio ask someone about. We can't answer that and the amount varies from person to person anyway.
