This is never a good situation - it does depend greatly on the insurance companies policies however the process is usually much more drawn out. In a regular claim your insurance company is fighting with theirs to get the money for your car. In this case they are fighting themselves so the 'sense of urgency' seems to evaporate. Make sure you really push them and keep them on their toes - just incase. This of course does not always apply but it is quite common in claims that have the same insurer.
yes. you can sue an at fault driver if his insurance company refuses to pay your claim. it would not be proper to sue the insurance company.
You do not have to reimburse your insurance company if the accident is the fault of the other driver and the claim is made on their insurance. If the accident is the fault of the other driver and their insurance does not cover everything and you make a claim on your insurance for reimbursement, your insurance will subrogate (collect back) from the other company.
claim rejected
You can only claim against the rental company if the driver took out their insurance. If he has his own separate insurance, that is where you need to make the claim.
Almost certainly.
If the other party is refusing to call their insurance company - then you should call their insurance company and file the claim.
Sorry, the driver with no insurance can claim of your insurance. He/she has no legal right to lodge such unauthorised claim.
It is up to the driver to subit the auto accident claim. You should submit the claim as soon as possible after the accident.
A claim is a liability on part of the insurance company. If a customer makes a claim it means that the insurance company has to pay the customer for the amount is eligible to claim and hence it is a expenditure on the balance sheets of the insurance company.
You can file a claim with your insurance company. You can also get a lawyer and file a lawsuit against the drunk driver.
The fact that you don't have insurance doesn't preclude you from collecting from the at-fault party. Call the other driver's insurance company and file a claim for damages.
First you need to be certain of who is legally liable for the damage. Insurance companies seldom refuse to pay damages unless the claim is unsubstantiated. If you have undisputable proof the other driver was at fault, then you can sue that person. -Additional - In most jurisdictions you have to sue the driver/owner and not the insurance company directly. The small claims court clerk can tell you for sure. The insurance company will defend the other driver/owner and pay the claim if you win in court.
