A Contractor End of Contract Letter is a formal document that is issued when an agreement between two parties (such as a contractor and a client) has come to an end. This document provides written confirmation that the contractor’s services have been satisfactorily completed and that the relationship between the parties has been terminated. It may also be used to provide documentation of the termination, including any payments or refunds due to either party. In short, it serves as a form of legal protection for both parties – ensuring that all responsibilities and obligations have been honoured.
