A week ago a tenant advised that her car was damaged, most probably by the builder doing a reno in that part of the block of flats. The builder had to go past my tenant's car to get out. A short time ago I was advised that there were fresh scractches, and the car had not been moved today. On balance of probability it very much seems that the builder was careless. The damage is horizontal scratches, maybe $500-1000 to fix.. I know the owner's name but do not know his contact details. At this stage I want to keep it low-key, and find out what the owner says. If he baulks at paying for the damage then we can go to court. Should I ask the OC for the owner's details, or to pass on a message? Is there another course of action that could work? TIA.
