Final answer:
A successor auditor should request the review of the predecessor's workpapers.
Step-by-step explanation:
A successor auditor should request the new client to authorize the predecessor author to allow a review of the predecessor's workpapers.
Workpapers are documents prepared by auditors during an audit engagement and include audit planning, procedures performed, evidence obtained, and conclusions reached. They serve as a record of the auditor's work and provide support for the auditor's opinion.
By reviewing the predecessor's workpapers, the successor auditor can gain insights into the nature and extent of the previous audit, assess the quality of the work performed, and understand any significant findings or issues that may impact the current engagement.
