Companies must formalize auditor appointments through statutory filing requirements. Form ADT-1 serves as the official intimation to the Registrar of Companies regarding the appointment of an auditor. Proper filing ensures regulatory compliance, validates the auditor’s authority, and prevents penalties.
Many businesses rely on structured processes and professional auditor service support to ensure timely submission, accurate documentation, and compliance with provisions of the Companies Act. A clear approach reduces errors and avoids unnecessary resubmissions.
Purpose of Form ADT-1
Form ADT-1 notifies the Registrar about the appointment of an auditor under Section 139 of the Companies Act, 2013. It confirms that the company has completed the appointment process in accordance with legal requirements.
This filing applies to:
- First auditor appointment by shareholders
- Subsequent auditor reappointments
- Auditor appointments after casual vacancy (in certain cases)
The form creates an official record in the MCA database and establishes the auditor’s tenure.
When Filing Becomes Mandatory?
Companies must file Form ADT-1 within 15 days of the auditor’s appointment. The timeline begins from the date of the general meeting where shareholders approve the appointment.
Key situations requiring filing:
- Appointment of a new auditor
- Reappointment after completion of tenure
- Appointment following resignation of the previous auditor
Failure to meet deadlines triggers additional fees and compliance risks.
First Auditor vs. Subsequent Auditor Filing
The filing requirement differs depending on the type of appointment.
First Auditor
The Board of Directors appoints the first auditor within 30 days of incorporation. Filing ADT-1 for the first auditor remains optional, yet many companies still file it for record consistency.
Subsequent Auditor
Shareholders appoint the auditor at the Annual General Meeting. Filing ADT-1 becomes mandatory in this case.
Documents Required Before Filing
Preparation begins with gathering supporting documents. Missing documentation leads to rejection.
Ensure availability of:
- Auditor’s consent letter
- Eligibility certificate under Section 141
- Copy of the resolution passed at AGM

- Digital Signature Certificate of the authorized signatory
Accurate documentation speeds up approval.
