Auditor Appointment Under Section 139: ADT-1 and First Auditor Checklist

Finin2min Compliance Desk·June 2026·7 min readADT-1

Auditor appointment is one of the earliest governance controls for a company. Section 139 separates first-auditor appointment from AGM appointment, and the compliance file should prove consent, eligibility, board/shareholder approval and filing trail.

Section 139 core

Section 139 says every company shall, at the first annual general meeting, appoint an individual or firm as auditor. It also provides that the first auditor of a company other than a Government company shall be appointed by the Board within thirty days from the date of registration.
