Damage occurred by 3rd party who is liable contractor or owner?

Liability for damage caused by a third party can depend on the terms of the contract between the contractor and the owner, as well as the nature of the damage. If the contractor was acting within the scope of their work and the damage resulted from their negligence, the contractor may be held liable. Conversely, if the owner failed to provide a safe environment or adequate instructions, they could also bear responsibility. Ultimately, the specifics of the situation and applicable laws will determine liability.
