An insurance company has a right to investigate a claim to determine who was at fault. The company will use any available information, including sources outside of the police report, and can and will assign fault if there is no report. If fact, even if the police report finds the other driver at fault, the insurance company can assign fault to you. The insurance company does not have the final say as to fault. Rather, the court does. If your insurance company made a decision to pay the other driver, there is really no procedure to go to court to prevent your insurer from paying the claim. If you have filed a claim, and the other driver's insurance has denied the claim, you can go to court and force them to pay if you win.
