ADT-1 Filing
ADT-1 Filing in India by Legal Experts
Introduction
Auditor Appointment Compliance Made Simple
ADT-1 filing is a mandatory compliance under the Companies Act, 2013. Essentially, it is used to inform the Registrar of Companies (ROC) about the appointment of a company auditor. Therefore, every company must file ADT-1 within 15 days of appointing an auditor to avoid penalties.
However, many companies face fines simply due to delayed or incorrect ADT-1 filing. In such cases, Prospect Legal helps companies file ADT-1 correctly and on time, thereby ensuring stress-free compliance.

What is ADT-1 Filing?
ADT-1 is an official form filed with the ROC to notify the appointment of:
- First Auditor
- Subsequent Auditor
- Re-appointment of Auditor
In other words, it ensures transparency and confirms that your company’s financial audits are handled by a legally appointed auditor.
