Auditors often encounter areas within an audit engagement that require specialized knowledge or skills beyond their expertise. In such cases, they may engage an expert to provide insights on matters such as valuations, actuarial estimates, legal interpretations, or complex financial instruments. However, reliance on an expert’s work introduces risks, making it essential for auditors to assess the expert’s competence, capabilities, and objectivity rigorously. The International Standard on Auditing (ISA) 620 (Using the Work of an Auditor’s Expert) provides comprehensive guidelines on evaluating these factors to ensure the reliability of audit evidence. This article explores the criteria and best practices for assessing an expert’s qualifications, independence, and suitability in the context of an audit.
