Accident damage who pays expert reports

Hello, with my parked car the driver’s mirror was driven off, read itself so far again up to small paint damage so far OK there are only a few noses away and hold paint scratcher.causer known insurance also everything OK wants to pay.So they wanted only an expert report on the damage amount if I want a fictitious processing, I wanted. Had the report prepared and must pay for it 60 Euro the total damage of the defective mirror was 627 Euro. but what about the report I have to get who pays it?However, if 527 euros are not paid the 60 euros for the report.Is this correct or does the insurance have to pay the 60 euros?
