Ownership of Audit Documentation

Standard on Quality Control (SQC) 1 provides that, unless otherwise specified by law or regulation, audit documentation is the property of the auditor. He may at his discretion, make portions of, or extracts from, audit documentation available to clients, provided such disclosure does not undermine the validity of the work performed, or, in the case of assurance engagements, the independence of the auditor or of his personnel.
