Authentication of Documents, Proceedings and Contracts (Section 21) including Key Managerial Personnel
# Authentication of Documents, Proceedings and Contracts — Section 21
Section 21 of the Companies Act, 2013 lays down who may authenticate a document or proceeding requiring authentication by a company, or sign contracts on its behalf.
## Who May Sign / Authenticate?
A document or proceeding requiring authentication by a company, or a contract made by or on behalf of a company, may be signed by:
### (1) Any Key Managerial Personnel (KMP)
As per Section 2(51), 'Key Managerial Personnel', in relation to a company, means:
1. The Chief Executive Officer (CEO) or the Managing Director or the Manager;
2. The Company Secretary;
3. The Whole-Time Director;
4. The Chief Financial Officer (CFO);
5. Such other officer not more than one level below the directors, who is in whole-time employment, designated as KMP by the Board; AND
6. Such other officer as may be prescribed.
### (2) An Officer or Employee duly authorised by the Board
Any officer or employee of the company duly authorised by the Board in this behalf may also sign such documents.
## Practical Significance
This section provides legal certainty about whose signature binds the company on its documents and contracts.
It eliminates ambiguity by either listing a closed class of KMP, OR allowing any person to act on the basis of express Board authorisation.
Without compliance, the authenticity of company documents may be challenged.
Worked example
### Example 1
Example 1 — Signing by KMP:
ABC Ltd. needs to authenticate a contract with a supplier. The CFO signs the contract on behalf of the company. The supplier later questions its validity.
Answer: The CFO is a Key Managerial Personnel under Section 2(51)(iv). Under Section 21, a KMP may authenticate company documents and sign contracts. The contract is validly authenticated.
### Example 2
Example 2 — Signing by an authorised employee:
XYZ Ltd.'s purchase manager, who is not a KMP, signs a supply contract. The supplier wants to confirm the contract is binding.
Answer: Under Section 21, even an officer or employee may sign if duly authorised by the Board in that behalf. If the purchase manager has been so authorised by a Board resolution, the contract is binding on the company; otherwise it is not.
⚠️ Common exam mistakes
Believing only directors can sign on behalf of the company — KMP and Board-authorised officers/employees may also sign.
Confusing KMP under Section 2(51) with merely senior managers; only the closed list (CEO/MD/Manager, CS, WTD, CFO, designated officer one level below directors, or prescribed officers) are KMP.
Forgetting that an ordinary employee may sign — but only if expressly authorised by the Board.
Treating the KMP category 'such other officer one level below directors' as automatic — it requires whole-time employment AND designation by the Board.
