Opinion as to handwriting and signature, when relevant
When the question is whose hand a document is in, the opinion of a person acquainted with that handwriting is relevant — and for an electronic signature, the opinion of the Certifying Authority that issued the certificate.
How to read Section 41
Familiar with the hand — or the Certifying Authority.
The opinion of a person acquainted with the handwriting — a lay witness, not a § 39 expert.
Seen him write, exchanged answering letters, or habitually handled his documents in business.
The opinion of the Certifying Authority that issued the Electronic Signature Certificate.
The bare Act
The section in its own words — colour-keyed by what each phrase does.
(1) When the Court has to form an opinion as to the person by whom any document was written or signed, the opinion of any person acquainted with the handwriting of the person by whom it is supposed to be written or signed that it was or was not written or signed by that person, is a relevant fact.
The question is, whether a given letter is in the handwriting of A, a merchant in Itanagar. B is a merchant in Bengaluru, who has written letters addressed to A and received letters purporting to be written by him. C, is B’s clerk whose duty it was to examine and file B’s correspondence. D is B’s broker, to whom B habitually submitted the letters purporting to be written by A for the purpose of advising him thereon. The opinions of B, C and D on the question whether the letter is in the handwriting of A are relevant, though neither B, C nor D ever saw A write.
(2) When the Court has to form an opinion as to the electronic signature of any person, the opinion of the Certifying Authority which has issued the Electronic Signature Certificate is a relevant fact.
In short: you do not need a handwriting expert to say whose writing a document is — anyone who genuinely knows the hand may give an opinion. The Explanation fixes how that familiarity may arise. For a modern electronic signature, the trusted opiner is the Certifying Authority that issued the certificate.
