The Wisconsin General Contractor's Affidavit of Completion and Release is a legal document that is used in construction projects or renovations to certify that a contractor has completed a job, and that all parties involved have agreed to the terms of the contract. The affidavit also releases the contractor from any further responsibility for the completion of the job and for any damages resulting from it. There are three types of Wisconsin General Contractor's Affidavit of Completion and Release. The first type is a Certificate of Final Completion, which is issued when the project is finished and all materials and labor have been paid for. The second type is a Certificate of Partial Completion, which is issued when some work has been completed, but not all. The third type is a Final Release, which is issued when the job has been completed and all parties agree that the work has been satisfactorily completed.
