Indian Evidence Act, 1872
126. Professional communication
No barrister, attorney, pleader or vakil shall at any time be permitted, unless with his client’s express consent, to disclose any communication made to him in the course and for the purpose of his employment as such barrister, pleader, attorney or vakil, by or on behalf of his client, or to state the contents or condition of any document with which he has become acquainted in the course and for the purpose of his professional employment, or to disclose any advice given by him to his client in the course and for the purpose of such employment:
Provided that nothing in this section shall protect from disclosure -
(1) Any such communication made in furtherance of any 87[illegal] purpose.
(2) Any fact observed by any barrister, pleader, attorney or vakil, in the course of his employment as such, showing that any crime or fraud has been committed since the commencement of his employment.
It is immaterial whether the attention of such barrister, 88[pleader], attorney or vakil was or was not directed to such fact by or on behalf on his client.
Explanation - The obligation stated in this section continues after the employment has ceased.
(a) A, a client says to B, an attorney-"I have committed forgery and I wish you to defend me".
As the defense of a man known to be guilty is not a criminal purpose, this communication is protected from disclosure.
(b) A, a client, says to, B, an attorney-"I wish to obtain possession of [property by the use] of forged deed on which I request you to sue".
This communication, being made in furtherance of a criminal purpose, is not protected from disclosure.
(c) A, being charged with embezzlement, retains B, an attorney, " to defend him. In the course of the proceedings B observes that an entry has been made in A’s account book, charging A with the sum said to have been embezzled, which entry was not in the book at the commencement of his employment.
This being a fact observed by B in the course of his employment, showing that a fraud has been committed since the commencement of the proceedings, it is not protected from disclosure.
