CS stands for Company Secretary. In Indian corporate and company law, a Company Secretary is a professionally qualified individual responsible for ensuring that a company complies with all applicable legal and statutory obligations, maintains proper corporate governance, and keeps accurate legal records.
The Company Secretary profession in India is regulated and governed by the Institute of Company Secretaries of India (ICSI), established under the Company Secretaries Act, 1980. The Companies Act, 2013 mandates that every company with a paid-up share capital of ₹5 crore or more must appoint a whole-time Company Secretary as a Key Managerial Personnel (KMP).
A CS wears many legal hats: corporate compliance officer, legal advisor to the board, liaison with SEBI/ROC/Stock Exchanges, and certifying authority for various regulatory filings.
