Documents Required for Filing Form ADT-1
Form ADT-1 is a statutory form that must be filed with the Ministry of Corporate Affairs (MCA) to notify the Registrar of Companies (ROC) about the appointment or reappointment of an auditor. Filing Form ADT-1 is mandatory under Section 139 of the Companies Act, 2013. However, before filing ADT-1, companies must collect and attach several key documents to ensure the filing is accurate, complete, and compliant with MCA requirements.
This article outlines all the documents required for filing Form ADT-1, explains their significance, and provides practical tips to help companies avoid delays, rejections, or penalties.
When is Form ADT-1 Required?
Form ADT-1 must be filed in the following situations:
- Appointment of the first auditor by the Board of Directors
- Appointment or reappointment of auditors at the Annual General Meeting (AGM)
- Appointment of an auditor to fill a casual vacancy (due to resignation, death, disqualification, etc.)
- Reappointment of an existing auditor after the expiry of the term
It must be filed within 15 days of the auditor's appointment.
Mandatory Documents for ADT-1 Filing
Here’s a detailed list of the documents that must be attached to Form ADT-1:
1. Board Resolution or Shareholders’ Resolution
Depending on who appoints the auditor, either of the following is required:
- Copy of Board Resolution: If the auditor is appointed by the Board (e.g., for first auditor or in case of a casual vacancy), the certified true copy of the board resolution approving the appointment is mandatory.
- Copy of Shareholders' Resolution (AGM/EGM): If the auditor is appointed or reappointed at the AGM or an EGM, the resolution passed by the members must be attached.
Tip: Ensure that the resolution clearly mentions the name of the auditor, term of appointment, and their firm registration number.
2. Auditor’s Consent Letter
A written consent from the proposed auditor or audit firm is essential. This document confirms that the auditor agrees to accept the appointment.
It should include:
- Name and membership number of the auditor
- A statement declaring their willingness to be appointed
- Signature and date
Tip: Obtain this consent before the Board or shareholders pass the resolution.
3. Eligibility Certificate Under Section 141
As per Section 141 of the Companies Act, the auditor must certify their eligibility and non-disqualification to act as an auditor of the company.
This certificate must declare:
- That the auditor is not disqualified under Section 141(3)
- The appointment complies with the limits specified under Section 141(3)(g)
- They are not in contravention of the code of ethics or any pending professional misconduct cases
Tip: Always check that the eligibility certificate is printed on the auditor’s letterhead and duly signed.
4. Copy of Intimation Sent to the Auditor
The company must officially inform the newly appointed auditor about their appointment via a formal communication.
This intimation should include:
- Name of the company
- Date and reference of the board/shareholders' meeting
- Term of appointment
- Any other relevant details
Attach a copy of this communication to Form ADT-1 as proof of formal intimation.
Additional Documents (If Applicable)
Depending on the nature of the appointment, the following may also be required:
5. Copy of Auditor Resignation Letter (in case of Casual Vacancy)
If the appointment is to fill a casual vacancy due to resignation, attach a copy of the resignation letter from the outgoing auditor. This letter should mention the reason and effective date of resignation.
6. Copy of EGM Notice & Explanatory Statement (If applicable)
If the auditor is appointed at an Extraordinary General Meeting (EGM), a copy of the notice and explanatory statement sent to shareholders should also be attached.
This is particularly applicable in case of resignation, where shareholder approval is required within 3 months.
7. PAN and Membership/Firm Registration Details of the Auditor
While not separately attached, these details must be accurately entered in the form. Keep a copy of the PAN card and ICAI membership certificate handy for verification.
8. Digital Signature Certificate (DSC)
Though not a file attachment, Form ADT-1 must be digitally signed using the Digital Signature Certificate of:
- One Director of the company
- A practicing Chartered Accountant (CA), Company Secretary (CS), or Cost Accountant (CMA)
Tip: Ensure both DSCs are valid and registered on the MCA portal before filing.
