Section 92 Evidence Act: Exclusion of Oral Agreement Evidence

Section 92 of the Indian Evidence Act, 1872 restricted oral evidence used to contradict or change the proved terms of written instruments. The corresponding current rule is Section 95 of the Bharatiya Sakshya Adhiniyam, 2023 (BSA), which took effect on 1 July 2024.

What Section 92 means: the main rule

Once the terms of a contract, grant, disposition of property or other matter required by law to be documented have been proved in accordance with former Section 91 (now BSA Section 94), parties to the instrument and their representatives in interest generally cannot introduce an oral agreement or statement to contradict, vary, add to or subtract from those terms.

The rule protects the integrity of documented transactions. It does not mean that every oral statement is inadmissible: the statute expressly recognises six qualifications, explained below. The BSA restates them as successive provisos rather than numbered provisos.

Six provisos: when oral evidence may be admitted

1. Invalidity of the document or grounds for relief

Facts may be proved that would invalidate the document or justify a related decree or order, including fraud, intimidation, illegality, lack of due execution, lack of capacity, want or failure of consideration, or mistake of fact or law. A party may therefore offer evidence that consent was procured by misrepresentation or that the document contains a legally relevant mistake.

2. A separate agreement on a matter left unstated

A separate oral agreement may be shown where the written instrument is silent on that matter and the oral term does not conflict with its express terms. The court must consider the document's formality: a detailed, professionally prepared agreement is less likely to permit supplementation than a brief informal note.

3. Oral condition precedent

Evidence is permitted of a separate oral condition that had to occur before an obligation under the document became operative. This addresses whether the written obligation ever took effect, rather than rewriting its terms.

4. A later oral agreement rescinding or modifying the transaction

A distinct subsequent oral agreement may be proved, except where the underlying contract, grant or disposition is required by law to be in writing or has been registered under the applicable registration law. The statutory restrictions on later oral modifications must be checked before relying on this proviso.

5. Usage or custom

Evidence of a relevant trade usage or custom may establish incidents normally attached to contracts of that type, provided the incident is not repugnant to or inconsistent with the express written terms.

6. Facts connecting language with existing circumstances

Evidence may establish how the language of the instrument relates to real-world facts, such as identifying the property, person or subject matter to which a description refers. This is not a licence to contradict an otherwise unambiguous contractual term.

Illustrations under former Section 92

The original statutory illustrations are retained below, with historical names, dates and amounts preserved. They show how the rule and provisos operate in different circumstances.

1. (a) A policy of insurance is effected on goods in ships from Calcutta to London. The goods are shipped in a particular ship which is lost. The fact that particular ship was orally excepted from the policy cannot be proved.
2. (b) A agrees absolutely in writing to pay B Rs. 1,000 on the first March 1873. The fact that, at the same time an oral agreement was made that the money should not be paid till the thirty-first March cannot be proved.
3. (c) An estate called the Rampore tea estate is sold by a deed which contains a map of the property sold. The fact that land not included in the map had always been regarded as part of the estate and was meant to pass by the deed cannot be proved.
4. (d) A enters into a written contract with B to work certain mines, the property of B, upon certain terms. A was induced to do so by a misrepresentation of B as to their value. This fact may be proved.
5. (e) A institutes a suit against B for the specific performance of a contract, and also prays that the contract may be reformed as to one of its provisions, as that provision was inserted in it by mistake. A may prove that such a mistake was made as would by law entitle him to have the contract reformed.
6. (f) A orders goods of B by a letter in which nothing is said as to the time of payment, and accepts the goods on delivery. B sues A for the price. A may show that the goods were supplied on credit for a term still unexpired.
7. (g) A sells B a horse and verbally warrants him sound. A gives B a paper in these words: "Bought of A a horse of Rs. 500." B may prove the verbal warranty.
8. (h) A hires lodgings of B, and gives B a card on which is written - "Rooms, Rs. 200 a month". A may prove a verbal agreement that these terms were to include partial board. A hires lodgings of B for a year, and a regularly stamped agreement, drawn up by an attorney, is made between them. It is silent on the subject of board. A may not prove that board was included in the term verbally.
9. (i) A applies to B for a debt due to A by sending a receipt for the money. B keeps the receipt and does not send the money. In a suit for the amount, A may prove this.
10. (j) A and B make a contract in writing to take effect upon the happening of a certain contingency. The writing is left with B, who sues A upon it. A may show the circumstances under which it was delivered.

Practical application in litigation

• First prove the document: Establish the written terms under BSA Section 94, including applicable rules on primary or secondary evidence.
• Identify the parties: Section 95 primarily regulates proof between parties to the instrument and their representatives in interest; the precise relationship of the litigants matters.
• Specify the proviso: A party relying on oral evidence should identify whether it concerns invalidity, a consistent collateral agreement, a condition precedent, subsequent modification, custom or the application of language to facts.
• Check mandatory formalities: Registration, statutory writing requirements and other substantive laws can restrict an alleged oral modification.
• Distinguish explanation from contradiction: Evidence that identifies the property described is different from evidence intended to replace the property described.

How Section 92 differs from Section 91

Former Section 91 (BSA Section 94) addresses how the terms of a documented transaction must be proved. Former Section 92 (BSA Section 95) addresses when oral evidence cannot alter those proved terms. Both rules should be considered together.
