It would depend on why the car was totaled and who's fault the accident was and what time of insurance do you have PLPD or Full Coverage
There's a good chance the insurance company will deny the claim of the person with the uninsured vehicle, as that vehicle isn't supposed to be on the roadway to begin with.
It depends on the company and policy. Some will deny it for "operating out of territory". Others will cover it and then non-renew the policy for "operating out of territory". There is no way to say for sure as it varies so much from company to company.
Sure. Remember that an insurance policy is a legal contract wherein the insurance company agrees to accept risk from the policy holder according to the terms of the contract. If the policy holder does not live up to the terms of the contract then the insurance company may deny coverage. For example, if the person lied to the insurance company on the application then the insurance company may deny coverage. One of the terms of the policy is that the insured agrees to inform the insurance company of all residents of the home as well as regular drivers. If the insured does not list his 17 year old child who drives one of the vehicles regularly and lives in the house and then the child has an accident the insurance company could not be expected to provide coverage for the accident. Since the insured broke the terms of the policy which is a legal contract then the company probably will not provide coverage because the insured committed material misrepresentation and lied in a significant manner on the application.
Being going for legal tussle, it's better to approach Insurance Ombudsman under whose jurisdiction your Insurance Co. falls with all papers/documents. However, their verdict will be binding on both you and your insurer.
No health insurance company denies anyone health insurance for being gay.
not legally, if they find out your address is wrong the insurance company can deny a claim
Probably only if you have full coverage. Otherwise the Insurance company will deny you.
Yes, you can put in an insurance claim for any reason. It is up to them to pay or deny any claim. It will be tough to determine which damage was there prior to any other accident.
Since you were not driving legally and had no legal right to be where the accident took place, the insurance company may deny the claim. You would likely win in court, but that doesn't get your car fixed now..
