Contract of Sale: Sale and Agreement to Sell

Updated 10 October 2026 · Fact-checked

A contract of sale is a contract where the seller transfers or agrees to transfer the property in goods to the buyer for a price (Section 4). If property passes now, it is a sale. If property passes later or on a condition, it is an agreement to sell. You decide by asking when ownership moves.

Understand Contract of Sale: Sale and Agreement to Sell

The Sale of Goods Act, 1930 deals with one thing: the movement of property (ownership) in goods from a seller to a buyer for a price. Section 4(1) defines a contract of sale on this basis. It also says there may be a contract of sale between one part-owner and another.

From the definition you get the essentials. There must be two parties, a buyer and a seller, and they must be different persons (apart from the part-owner case). The subject matter must be goods. There must be a price in money. The contract must transfer or agree to transfer property, not just possession. Like any contract, it is made by an offer and acceptance (Section 5), and it may be in writing, by word of mouth, partly both, or implied from conduct.

A contract of sale may be absolute or conditional (Section 4(2)). Now the key split. Where property passes from seller to buyer under the contract, it is called a sale. Where the transfer is to take place at a future time, or subject to some condition still to be fulfilled, it is called an agreement to sell (Section 4(3)). An agreement to sell becomes a sale when the time elapses or the conditions are fulfilled (Section 4(4)).

The goods may be existing goods owned or possessed by the seller, or future goods (Section 6). If the seller purports to make a present sale of future goods, the contract operates only as an agreement to sell. This is a favourite exam point.

Why does the difference matter? A sale is a contract plus a transfer of ownership, so the buyer gets rights in the goods themselves (in rem). Under an agreement to sell, property has not yet passed. The buyer's usual remedy against a defaulting seller is a suit for damages. Rights in the goods themselves arise only after the property passes.

Section 8 is a separate rule. It applies to an agreement to sell specific goods that perish, without fault of either party, before the risk passes to the buyer. The agreement is then avoided. It is not a consequence of the damages remedy.

Sale also differs from similar transactions. In bailment, only possession passes and the goods must be returned, and there is no price for transfer of ownership. In hire purchase, the hirer gets possession and an option to buy. The hirer is not bound to buy, so hire purchase is not treated as a sale under the Act. It is governed by the terms of the hire-purchase agreement. As a general position, property passes when the hirer exercises the option under the agreement, usually after paying all instalments. A gift has no price. An exchange or barter has goods for goods, not a money price.

Key rules to remember

Definition of contract of sale (Section 4(1)): Contract of sale = seller transfers or agrees to transfer property in goods to buyer for a price; Learn the four elements: parties, goods, price, transfer of property.
Sale (Section 4(3)): Sale = property in goods passes from seller to buyer under the contract; It is an executed contract. It creates rights in the goods themselves (in rem).
Agreement to sell (Sections 4(3), 4(4)): Agreement to sell = transfer of property at a future time or subject to a condition; becomes a sale when the time elapses or the condition is fulfilled; It is an executory contract. The buyer's usual remedy against a defaulting seller is a suit for damages. Rights in the goods themselves arise only after property passes.
Present sale of future goods (Section 6(3)): Present sale of future goods = agreement to sell; Seller cannot pass property in goods he does not yet own or have.
Perishing of specific goods (Section 8): Specific goods perish without fault of either party before risk passes to buyer, after agreement to sell → agreement avoided; Applies to an agreement to sell, not to a completed sale. It is a separate rule, not a result of the damages remedy.

How to solve Contract of Sale: Sale and Agreement to Sell questions

Use this method for any question that asks you to classify a transaction or to distinguish sale from agreement to sell or other transactions.

1Read the facts and find what is being transferred: ownership (property) or only possession.
2Check the four essentials: two parties, goods, money price, transfer of property. If any is missing, it is not a contract of sale.
3Ask when property is to pass. If now, it is a sale. If at a future date or on a condition, it is an agreement to sell.
4Check whether the goods are existing or future goods. A present sale of future goods is only an agreement to sell (Section 6(3)).
5Compare with look-alike transactions: bailment (return of the same goods), hire purchase (option to buy), gift (no price), barter (no money price).
6State the legal effect: rights in the goods for a sale, a claim for damages for an agreement to sell, and Section 8 if specific goods perish.
7Write a one-line conclusion that names the section.

Quickest way: One-question test: when does ownership move?

When to use it: Use it for MCQs and short distinction questions where you have two minutes.

Underline the words that show timing: 'will', 'on payment', 'after delivery', 'on approval', 'later'.
If ownership moves at once, pick sale. If timing or a condition is attached, pick agreement to sell.
If the buyer can return the same goods or has only an option to buy, think bailment or hire purchase, not sale.
If there is no money price, rule out sale.

Common mistakes in Contract of Sale: Sale and Agreement to Sell

Treating every contract to buy goods as a sale.
Students focus on delivery and payment, not on transfer of property.
Fix: Always ask when property passes. Future or conditional transfer means an agreement to sell under Section 4(3).
Calling a present sale of future goods a sale.
The word 'sale' appears in the facts, so students accept it.
Fix: Remember Section 6(3): it operates as an agreement to sell.
Saying hire purchase is a sale because the hirer eventually owns the goods.
The end result looks like a sale.
Fix: The hirer is not bound to buy, so hire purchase is not treated as a sale under the Act. It is governed by the terms of the hire-purchase agreement. As a general position, property passes when the hirer exercises the option under the agreement. Until then the hirer can usually return the goods and stop paying, as the agreement provides.
Confusing possession with property.
Everyday language uses 'owning' and 'having' loosely.
Fix: Bailment and hire transfer possession only. A contract of sale needs transfer of property.
Writing that an agreement to sell gives the buyer rights over the goods.
Students mix up the two positions.
Fix: Under an agreement to sell the buyer's usual remedy against a defaulting seller is a suit for damages. Rights in the goods themselves (in rem) arise only after the property passes.
Ignoring Section 8 when specific goods are destroyed.
Students jump to breach and compensation.
Fix: Check fault and whether risk has passed. If no fault and risk has not passed, the agreement to sell is avoided.

Worked examples

Example 1

Ravi Traders agrees on 1 March to sell a specific machine to Meera Industries for ₹4,00,000. Property is to pass on 1 June, after full payment. Is this a sale or an agreement to sell? What happens if the machine is destroyed by lightning on 15 April without anyone's fault, before risk passes to Meera Industries?

Show the solution

Essentials: two parties, specific goods (a machine), a money price of ₹4,00,000, and an intention to transfer property. It is a contract of sale under Section 4(1).
Timing: property is to pass on 1 June, a future date, and on a condition (full payment). So under Section 4(3) it is an agreement to sell.
Effect of destruction: the goods are specific, the agreement is to sell, and the machine perished without fault of either party before risk passed to the buyer.
Section 8 applies, so the agreement is avoided.

Answer: It is an agreement to sell, not a sale. On destruction of the machine without fault and before risk passes, the agreement is avoided under Section 8.

Example 2

Distinguish between a sale and an agreement to sell on any four points.

Show the solution

Meaning: in a sale, property passes to the buyer at once under the contract. In an agreement to sell, property passes at a future time or on a condition (Section 4(3)).
Nature: a sale is an executed contract. An agreement to sell is executory and becomes a sale when the time elapses or the condition is fulfilled (Section 4(4)).
Rights created: a sale gives the buyer rights in the goods themselves, as owner. Under an agreement to sell, property has not passed, so the buyer's usual remedy against a defaulting seller is a suit for damages.
Risk and perishing: in a sale the goods are generally at the buyer's risk once he is owner. If specific goods perish without fault before risk passes under an agreement to sell, the agreement is avoided (Section 8).
Conclude with the test: ask when property passes.

Answer: Sale: property passes now, executed contract, rights in the goods, buyer bears the loss as owner. Agreement to sell: property passes later or on a condition, executory contract, buyer's usual remedy against a defaulting seller is damages, and Section 8 may avoid it if specific goods perish without fault before risk passes.

Exam tips

Distinction questions are common. Write four or five points in two columns, each with a section reference where you can.
In MCQs, look for timing words such as 'will pass on' or 'subject to payment'. They signal an agreement to sell.
For hire purchase versus sale, stress that the hirer is not bound to buy and that, as a general position, property passes when the option is exercised under the agreement.
Quote Section 4(3) and 4(4) exactly in meaning. Keep your own words short and precise to earn step marks.
In case-based answers, give a clear verdict first, then the reasoning, then the section.
