A letter of engagement is basically a statement issued by the auditor to his client preferably before the commencement of the audit to help avoid mis-understandings with respect to the engagement.
The letter documents and confirms the auditor‘s acceptance of the appointment, the objective and scope of the audit, the extent of auditor‘s responsibilities to the client and the form of any reports.
It enables the client and auditor know and understand their responsibilities. It also reminds management of their duty towards accounts and the internal control system.
It would be helpful to the auditor in case of supporting himself when charged with negligence.
