SA 580 requires the auditor, if management does not provide one or more of the requested written representations, to discuss the matter with management, re-evaluate the integrity of management and the reliability of representations and evidence obtained throughout the audit, and take appropriate action — which, if the required representations (including the two specified representations on fulfilling responsibility for the financial statements and for providing complete information) still cannot be obtained, means a disclaimer of opinion, because the inability to obtain them is itself treated as a scope limitation sufficient to prevent an opinion being formed.
Qualified sign-back vs outright refusal — SA 580 treats both as a trigger
| Scenario | What SA 580 requires |
|---|---|
| Management signs with wording changed or a caveat added to a specific representation | Evaluate why the wording was changed — if it suggests the original representation would not have been accurate, this needs investigation, not acceptance of the amended wording at face value |
| Management omits one representation while signing the rest | Treated the same as a refusal for that specific representation — follow-up discussion and re-evaluation of reliability is required, not simply noting the gap |
| Management refuses to sign at all | Discuss with management; consider the effect on the auditor's ability to rely on other representations made during the audit, and consider the implications for the opinion |
| Management provides the representations, but other evidence during the audit casts doubt on their reliability | SA 580 treats doubt about reliability as equivalent in effect to not having obtained the representation — the auditor has to determine the effect on the audit and on the audit opinion |
What has to happen before concluding on a disclaimer
- 01Discuss the specific matter with management directlyUnderstand precisely why a representation is being qualified or withheld — the reason itself may point to a deeper issue (e.g. management genuinely unsure of a legal position) distinct from unwillingness to represent.
- 02Re-evaluate the reliability of representations obtained earlier in the auditIf one representation turns out doubtful, SA 580 requires considering whether that casts doubt on representations already relied on elsewhere in the file.
- 03Consider the effect on evidence obtained through management inquiry generallyMuch audit evidence beyond formal representations also rests on management's word — a credibility problem in one area has to be weighed against reliance elsewhere.
- 04Communicate with those charged with governanceA refusal or a material qualification on a representation is squarely the kind of significant matter SA 260 requires to be communicated, not resolved quietly between the engagement team and management alone.
Accepting a representation letter with the two specified representations — responsibility for the financial statements, and having provided all relevant information — removed or materially reworded at management's request is not a documentation convenience. SA 580 is specific that these two cannot be omitted; their absence, on its own, is treated as sufficient grounds for a disclaimer of opinion.
This is practical guidance written for audit teams, not an authoritative statement of any standard or statute. Standards, forms and timelines change. Check the current text issued by the ICAI and the relevant authority before relying on anything here in an audit file.
