ADT-3 Filing – Auditor Resignation Intimation

Form ADT-3 is the notice an auditor files with the Registrar of Companies on resigning from a company. We help auditors and companies complete the ADT-3 filing within the statutory time limit and keep the related records in order.

File Your ADT-3

What is Form ADT-3?

When a statutory auditor resigns from a company, Section 140(2) of the Companies Act, 2013 read with Rule 8 of the Companies (Audit and Auditors) Rules, 2014 requires the resigning auditor to file Form ADT-3 with the Registrar of Companies. The form states the reasons for resignation and any other facts relevant to it.

The obligation to file ADT-3 rests on the auditor, not the company. Once the auditor resigns, the company must fill the resulting casual vacancy and report the new appointment through Form ADT-1. We handle both sides of the process.

Who Needs to File ADT-3?

Statutory auditors resigning before the end of their appointed term.
Auditors of private and public limited companies.
Auditors of One Person Companies and other companies registered under the Act.
Audit firms recording the resignation of a partner-signed engagement.
Auditors who need a clean, on-record exit with reasons stated.
