A witness can never talk about a document without producing it.

They can, if the statement is about someone's own words or motive (a fact in itself), not about proving the document's actual contents.

The rule bans all oral evidence about agreements.

It only requires the actual document when the court believes the document itself should be examined; secondary evidence (like certified copies) is allowed if properly justified.

Section 147

Evidence as to matters in writing

Any witness may be asked, while under examination, whether any contract, grant or other disposition of property, as to which he is giving evidence, was not contained in a document, and if he says that it was, or if he is about to make any statement as to the contents of any document, which, in the opinion of the Court, ought to be produced, the adverse party may object to such evidence being given until such document is produced, or until facts have been proved which entitle the party who called the witness to give secondary evidence of it. Explanation.—A witness may give oral evidence of statements made by other persons about the contents of documents if such statements are in themselves relevant facts. Illustration. The question is, whether A assaulted B. C deposes that he heard A say to D— “B wrote a letter accusing me of theft, and I will be revenged on him”. This statement is relevant, as showing A's motive for the assault, and evidence may be given of it, though no other evidence is given about the letter.§

Why this exists

This rule continues the long-standing evidentiary principle (inherited from the Indian Evidence Act, 1872) that written documents are usually the 'best evidence' of their own contents. It prevents parties from testifying loosely about what a contract or deed said when the paper itself is available and more reliable. At the same time, it recognizes that sometimes a spoken statement *about* a document matters as a fact in itself — such as showing someone's intent or motive — regardless of whether the document is ever produced.
