Although you do not mention it, it appears as though you do not have any information regarding who did this to your car. If you did you would contact the police to file a report and get the at-fault party's insurance information. You then could make a Property Damage Liability claim for the damages to your car. If you don't know who scratched your car door with their car door then you can file a claim with your insurance company if you have physical damage (Comprehensive and Collision coverage). If you file with your insurance company, you must pay the deductible. If you do not have Collision coverage than unless you found the at-fault party you would have to pay for your own repairs. If you do have Collision coverage and do know who was at fault then if you make a claim your insurance company will work to recover damages (including the deductible) from the at-fault party's insurance company if the at-fault party is known. This is called subrogation. Most policies have a subrogation clause that enables your insurance company to obtain reimbursement from the at-fault party's insurance company for the cost of repairing your vehicle. This is the amount your insurance company actually paid out plus your deductible amount. [Let CarInsurance.com help you find affordable auto insurance now.]

If your state has a Comparative Negligence Law then the fault for an accident is not always placed squarely on one participant. After determining the percentage of fault by each party, the compensation by the insurance company is adjusted accordingly. Allocation of fault is made by negotiation between the insurance company and the claimant. There are state-by-state variations in how comparative negligence works. If the other company accepts 100% liability, then reimbursement is for the entire deductible amount. If the other driver involved in the accident is partially liable for the accident, their carrier will pay a percentage of the collision payment, and your deductible amount. You will be reimbursed the percentage of your deductible that was able to be recovered. You can comparison shop your policy by getting a car insurance quote here. |
