Hello,

The auditor of my pvt ltd co. is not signing the form ADT-3, citing flimsy reasons. What action should I take in order to appoint a new auditor in his place? We want to hire a new auditor for FY 2015-16.The auditor in question signed-off on the audit report for FY 2014-15. I have with me a letter from the ex-auditor, dated 03.09.2014, which says that he consents to his reappointment for the period ending 31.03.2019.
