My car was parked in my sister’s driveway. A big limb fell out of their tree and hit the roof of my car. The roof of my car was dented in and the side mirror was knocked off. They’ve known this tree has dead limbs because limbs are always falling out of it. They’ve even talked about having this tree trimmed or cut down. A few years ago, a limb fell out of the same tree and broke the sun-roof in one of their cars.

Who should be responsible for the repairs on my car?
