Form ADT-1: Appointment of Statutory Auditor

Form ADT-1 is a mandatory filing that companies must submit to the Registrar of Companies (ROC) to intimate the appointment of their statutory auditor. Filed under Section 139 of the Companies Act, 2013, this form ensures that the ROC maintains accurate records of who is responsible for auditing the company's financial statements, thereby upholding corporate transparency and accountability.

The appointment of a statutory auditor is a critical governance requirement for all companies, as the auditor plays a vital role in verifying that the company's financial statements present a true and fair view of its financial position. This guide covers everything you need to know about ADT-1 filing requirements and procedures.
