You can always explain or add to a written contract using verbal testimony about what was 'really meant.'

Section 94 blocks oral evidence about the actual terms of a document once those terms are in writing — only the document or valid secondary evidence can prove the terms, subject to narrow exceptions.

If a document mentions any fact, that fact can never be challenged with oral evidence.

Explanation 3 makes clear that facts merely mentioned in a document (but not part of its actual contractual terms) can still be proved or disputed with oral evidence, as in the indigo payment illustration.

A will can only be proved by physically producing the original will in every case.

Exception 2 allows a will admitted to probate in India to be proved simply by producing the probate itself.

Section 94

Evidence of terms of contracts, grants and other dispositions of property reduced to form of

When the terms of a contract, or of a grant, or of any other disposition of property, have been reduced to the form of a document, and in all cases in which any matter is required by law to be reduced to the form of a document, no evidence shall be given in proof of the terms of such contract, grant or other disposition of property, or of such matter, except the document itself, or secondary evidence of its contents in cases in which secondary evidence is admissible under the provisions hereinbefore contained. Exception 1.—When a public officer is required by law to be appointed in writing, and when it is shown that any particular person has acted as such officer, the writing by which he is appointed need not be proved.§

Exception 2.—Wills admitted to probate in India may be proved by the probate. Explanation 1.—This section applies equally to cases in which the contracts, grants or dispositions of property referred to are contained in one document, and to cases in which they are contained in more documents than one. Explanation 2.—Where there are more originals than one, one original only need be proved. Explanation 3.—The statement, in any document whatever, of a fact other than the facts referred to in this section, shall not preclude the admission of oral evidence as to the same fact. Illustrations.§

(a) If a contract be contained in several letters, all the letters in which it is contained must be proved.§

(b) If a contract is contained in a bill of exchange, the bill of exchange must be proved.§

(d) A contracts, in writing, with B, for the delivery of indigo upon certain terms. The contract mentions the fact that B had paid A the price of other indigo contracted for verbally on another occasion. Oral evidence is offered that no payment was made for the other indigo. The evidence is admissible.§

(e) A gives B a receipt for money paid by B. Oral evidence is offered of the payment. The evidence is admissible.§

Why this exists

This is India's version of the 'best evidence rule' for documents, carried over from Section 91 of the Indian Evidence Act, 1872, largely unchanged in the Bharatiya Sakshya Adhiniyam, 2023. Once parties choose to put their agreement or the law requires a matter to be documented, the written text becomes the authoritative record. Allowing oral testimony to override or supplement it would invite fraud, faulty memory, and endless disputes about 'what was really agreed.' The rule protects the certainty and integrity of written transactions while still permitting oral evidence about facts that are genuinely separate from the document's own terms.

How courts read it

Indian courts, interpreting the identical predecessor provision (Section 91 of the Evidence Act, 1872), have consistently distinguished between proving the *terms* of a document (barred except by the document or valid secondary evidence) and proving *collateral facts* merely mentioned in it (allowed via oral evidence), as illustrated by the indigo and receipt examples. Courts have also read this section together with Section 92 (now Section 95 of the 2023 Act), which further restricts oral evidence contradicting or varying proved documents, while recognising standard exceptions like fraud, mistake, or want of consideration.
