The creation, organization, and review of audit working papers is one of the main tasks of the auditor, especially since an auditor can be legally liable if working papers are not prepared properly. In the Guide to Audit Working Papers, we discuss all aspects of what to include in working papers, as well as how to organize and review them. We also address several legal issues related to confidentiality and working paper ownership, both of which may become issues that the auditor will encounter.
