Contract Law Questions - What Is a Counter-Offer?

The contract law questions every student asks - answered.
Understanding counter-offers is essential for mastering contract formation. Many students struggle to distinguish a valid acceptance from a counter-offer, yet this distinction can determine whether a contract exists at all. This article explains what a counter-offer is, how it differs from acceptance, and why the famous case of Hyde v Wrench (1840) remains a cornerstone of English contract law.
What Is a Counter-Offer?
A counter-offer occurs when a person responds to an offer by proposing different terms rather than accepting the offer as it stands.
In contract law, acceptance must correspond exactly with the terms of the offer. This principle is often referred to as the mirror image rule. If a party attempts to change the terms of the offer, their response will generally be treated as a counter-offer rather than an acceptance.
Example
Suppose Alice offers to sell her car to Ben for £10,000.
Ben replies:
"I will buy it for £9,000."
Ben has not accepted Alice's offer. Instead, he has made a counter-offer.
At this point:
Alice's original offer is terminated.
Ben's response becomes a new offer.
Alice may accept or reject the counter-offer.
No contract exists unless Alice agrees to Ben's new terms.
Why Do Counter-Offers Matter?
Counter-offers play an important role in commercial negotiations. Parties often negotiate prices, delivery dates, quantities, or other terms before reaching an agreement. However, students must remember that every counter-offer has legal consequences.
A valid counter-offer generally:
Rejects the original offer.
Terminates the original offer.
Creates a new offer capable of acceptance.
This can be dangerous during negotiations because a party who rejects a favourable offer may not be able to return and accept it later.
The Leading Case: Hyde v Wrench (1840)
Facts
The defendant, Wrench, offered to sell his farm to Hyde for £1,000.
Hyde responded by offering £950 instead.
Wrench rejected this proposal.
Hyde then attempted to accept the original offer of £1,000.
Wrench refused to sell the farm, and Hyde brought a claim seeking to enforce the agreement.
Decision
The court held that no contract existed.
Hyde's proposal to purchase the farm for £950 amounted to a counter-offer.
By making the counter-offer, Hyde had rejected Wrench's original offer of £1,000.
Once the original offer had been rejected, it could no longer be accepted.
Therefore, Hyde could not later revive the original offer by attempting to accept it.
Why?
The case established a fundamental rule:
A counter-offer destroys the original offer.
Once a counter-offer is made, the original offer ceases to exist unless the offeror chooses to renew it. This principle remains good law today and frequently appears in contract law examinations.
Acceptance vs Counter-Offer
Students often confuse acceptance with a counter-offer.
Acceptance
Acceptance occurs when a party agrees to the exact terms proposed. For example:
Offer:
"I will sell my laptop for £500."
Response:
"I accept."
A binding contract is formed.
Counter-Offer
A counter-offer changes the terms. For example:
Offer:
"I will sell my laptop for £500."
Response:
"I will pay £450."
This is not acceptance.
Counter-Offer vs Request for Information
Many students incorrectly assume that any response seeking clarification constitutes a counter-offer. This is not correct. A request for information merely seeks further details and does not reject the original offer.
The distinction was explored in Stevenson, Jacques & Co v McLean (1880). In that case, a question about whether the other party would consider different delivery terms was held to only be a request for information (and not a counter-offer).
The difference here is that an inquiry about whether the other party might consider alternative terms does not amount to a counter-offer. However, it is clear that the difference between a counter-offer and a request for information can be a fine one. This distinction is one that students often struggle to grapple with. There are usually two factors when attempting to make the distinction:
Is one party purporting to accept but at the same time trying to change the terms (counter-offer) or are they trying to decide whether to ask by seeking more information on the terms offered (request for information)?
How certain is the language used? Are they asking whether something else might be considered or is there an outright rejection of previously stated terms?
A Counter-Offer - In Summary

Key Takeaways
A counter-offer occurs when an offeree proposes different terms instead of accepting an offer.
Acceptance must correspond exactly with the terms of the offer.
A counter-offer generally terminates the original offer.
The leading authority is Hyde v Wrench (1840).
Once a counter-offer is made, the original offer cannot normally be accepted later.
A request for information is different from a counter-offer and does not terminate the original offer.
Distinguishing between acceptance, counter-offers, and requests for information is crucial in contract law examinations.
