Incorporation

File Your ADT-1 (Auditor Appointment)

We file your company's ADT-1 auditor appointment: first auditor, 5-year reappointment, replacement, or a casual vacancy, within the applicable 15-day window. Documentation and filing facilitation only.

ADT-1 covers a fixed 5-year auditor term rather than an annual filing, and you only refile on reappointment, replacement, or a casual vacancy. We handle whichever of those applies to you, filed within the 15-day window.

If you've read our article on why ADT-1 isn't an annual filing, you already know the 5-year rule. This service is the filing itself: whichever event triggers it, first auditor, reappointment at the end of a 5-year term, replacement, or a casual vacancy being filled, we prepare the resolution, collect the auditor's consent, and file within the 15-day deadline.

Scope

What's included

  • Drafted per the trigger: first auditor, reappointment, replacement, or casual vacancy.

  • Collected from the appointed auditor before we file anything.

  • Filed within 15 days of the triggering resolution.

Specifics

The details

When you actually need this

A statutory auditor's term runs from the AGM of appointment to the conclusion of the 6th AGM after it, a fixed 5 years under Section 139(1) of the Companies Act, 2013. One ADT-1 covers that whole term. You refile only when the term ends and the auditor is reappointed, when the auditor is replaced, or when a casual vacancy, resignation, death, or disqualification, is filled.

This is different from the first-auditor ADT-1 requirement that became mandatory in July 2025. That's a one-time filing at incorporation. This service covers the ongoing 5-year term after that first appointment, and the events that trigger a refiling within it. See our article for the full distinction.

The deadline

ADT-1 is due within 15 days of the triggering board or shareholder resolution itself, which is usually a different date from your AGM. We track this from the moment the resolution is passed.

Common mistakes founders make

  • Filing ADT-1 every year out of habit, when one filing covers the entire 5-year term.
  • Confusing this with the separate first-auditor ADT-1 requirement that applies at incorporation.
  • Missing the 15-day window after a reappointment, replacement, or casual-vacancy resolution.

Clarifications

Frequently asked questions

No. A statutory auditor's term runs 5 years, and one ADT-1 covers that whole term. You only refile on reappointment, replacement, or a casual vacancy.

15 days from the board or shareholder resolution appointing, reappointing, or replacing the auditor.

No, that's a separate, one-time filing at incorporation. This service covers the ongoing 5-year term afterward.

That's a casual vacancy, and it needs its own ADT-1 once it's filled, within 15 days of the resolution.
