On some occasions, you may enter into a contract based on a mistaken belief. If this is the case, you may have certain rights to end the contract or you may not have to fulfil your obligations under the contract. This depends on the type of mistake you and the other party made. Navigating this area of law can be tricky because of the specific rules in the UK. This article will explain the concept of \u2018mistake\u2019 in contract law.&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What is a Mistake in Contract Law?<\/h2>\n\n\n\n<p>In contract law, one of the two parties holds a wrong belief before entering into a contract, constituting a \u2018mistake\u2019. It is worth keeping in mind that this definition of \u2018mistake\u2019 is technical and carries a specific legal meaning. This mistake may be about the:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>identity of the other party;<\/li>\n\n\n\n<li>subject matter of the contract can lead to a mistake if, for example, you believe you are purchasing free-range eggs, but you actually receive caged hen eggs;<\/li>\n\n\n\n<li>terms of the contract (for example, if you thought you were paying in monthly instalments but you are instead paying in weekly instalments); and<\/li>\n\n\n\n<li>nature of the contract.<\/li>\n<\/ul>\n\n\n\n<p>Over time, English common law has refined the rules on mistake. Each negotiating party has an obligation to the other under English law to refrain from deceiving them into signing a contract. In most cases, it is not legally necessary to disclose all information during discussions, but you must be careful not to give false information. A contract could be voidable even in the case of an innocent mistake. A voidable contract means it is unenforceable.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Mistakes and Misrepresentations<\/h3>\n\n\n\n<p>It is important to note that the law distinguishes between mistakes and misrepresentations. While both mistakes and misrepresentations can affect the validity of a contract, the law treats them differently. A mistake relates to a belief held at the time of contract formation, whereas a misrepresentation is a false statement that induces a party to enter into a contract.<\/p>\n\n\n\n<p>A misled party may choose to either set aside the agreement or pursue damages, or occasionally both. The specific rules, therefore, will vary depending on the exact factual situation. At the same time, there are different rules on the type of mistake. For example, there is a difference between mutual and unilateral mistakes.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Different Types of Mistakes in Contract Law<\/h2>\n\n\n\n<p>As mentioned, the rules on mistake will vary depending on who made the mistake and how. For example, you may have a:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>common mistake;<\/li>\n\n\n\n<li>mutual mistake; or<\/li>\n\n\n\n<li>unilateral mistake.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">1. Common Mistake&nbsp;<\/h3>\n\n\n\n<p>One of the types of mistake is a \u2018common mistake\u2019. Both parties can make a common mistake when they misunderstand the same aspect of the contract. The shared mistake must be about something that is a serious aspect of the contract \u2013 it cannot be about something not sufficiently serious.&nbsp;&nbsp;<\/p>\n\n\n\n<div  class=\"box box--icon box--info\">\n    <p>For example, imagine that you enter into a contract to buy a piece of equipment. Additionally, imagine that you and the other party did not realise the equipment did not work. In that case, this is likely to be a sufficiently serious common mistake.<\/p>\n<\/div>\n\n\n\n<p>In such situations, the court might determine that the parties did not create a contract at all. Alternatively, the court may decide that the parties created a contract, but it is void, making it a \u2018<a href=\"https:\/\/legalvision.co.uk\/commercial-contracts\/void-contract\/\">voidable contract<\/a>\u2019.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">2. Mutual Mistake<\/h3>\n\n\n\n<p>A mutual mistake occurs when each party misunderstands a different part of the contract. People often describe this as the parties being at \u2018cross-purposes\u2019. Sometimes, both parties misinterpret the contract terms. However, a court is unlikely to declare the contract void just because both parties made a mistake about its content. If the words and actions of the parties point to a single, clear interpretation of what they agreed on, the contract will still be enforceable.<\/p>\n\n\n\n<p>In this type of situation, a court might find that there is only one interpretation of the contract which would have been reasonable. If this is the case, you will still have a <a href=\"https:\/\/legalvision.co.uk\/commercial-contracts\/elements-legally-binding-contract\/\">binding contract<\/a>. However, if this is not possible, a court may find that you have a voidable contract, which means that your agreement may not amount to a legally enforceable contract.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">3. Unilateral Mistake<\/h3>\n\n\n\n<p>A unilateral mistake occurs when one party makes a mistake and the other party knows or should have known about it.<\/p>\n\n\n\n<div  class=\"box box--icon box--info\">\n    <p>Suppose two people enter into a contract. One party is mistaken about an important term of the contract, and the other person is aware of this. In this case, a court will often decide that there was no legally binding contract in the first place. A court will usually insist that there must be a \u2018meeting of the minds\u2019 for a contract to arise.<\/p>\n<\/div>\n\n\n\n<p>However, if one party makes a mistake about the facts of the contract, the situation is different. For example, if a person thought he was buying a vase from 1750, but the vase is from 1790, and the seller knows this, the contract might not bind the buyer. This only applies if the seller is aware of the buyer\u2019s mistake.&nbsp;<\/p>\n\n\n\n<p>In cases of unilateral mistake, the courts may void the contract if they find that the party who was not mistaken acted unconscionably.<\/p>\n\n\n\n\n<a href=\"#content-next\"\n   class=\"block p-4 mt-10 text-xl font-bold text-center text-white no-underline bg-gray-800 rounded-t-xl\">\n    Continue

If successful in proving the mistake, the courts may find the agreement void.&nbsp;<\/p>\n\n\n\n<p>The remedy for mistakes include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><a href=\"https:\/\/hallellis.co.uk\/rescission-contract-law-meaning\/\">rescission<\/a> \u2013 this puts the parties in their pre-contractual positions. This remedy is the one that makes the contract void; or<\/li>\n\n\n\n<li>rectification \u2013 this is where the written agreement is corrected to reflect the actual agreement reached by the parties.<\/li>\n<\/ul>\n\n\n\n<p>For a court to grant rectification, the party seeking rectification must be able to prove that the agreement does not reflect the parties\u2019 intentions. Overall, the remedies depend on the facts between the parties of the contract.&nbsp;<\/p>\n\n\n\n<p>It is best to contact a lawyer who will work with the parties to reach an agreement to resolve the situation. If the matter escalates, it will be for the court to decide whether to uphold the agreement. Generally, courts prefer to keep the contract and adjust the obligations through express or implied contract terms.&nbsp;<\/p>\n\n\n\n<p>Speaking to a qualified lawyer about your contracts and their enforceability before you use them is also important. A lawyer can review your contract to ensure its suitability for your unique business.&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Preventing Mistakes in Contracts<\/h2>\n\n\n\n<p>To avoid costly legal disputes, it is important to take a few simple but effective steps before signing any contract:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Do your homework:<\/strong> Gather all the key information and double-check the facts before agreeing to anything;<\/li>\n\n\n\n<li><strong>Keep communication clear: <\/strong>Make sure everyone involved understands the terms in the same way. Talk through the details and confirm the important points in writing; and<\/li>\n\n\n\n<li><strong>Get expert advice<\/strong>: For more complicated contracts, it is worth asking a legal professional to review the document. They can help ensure it accurately reflects what both sides actually agreed to.<\/li>\n<\/ul>\n\n\n\n<p>By taking these steps, you can minimise the risk of mistakes and safeguard your business against the potential liabilities of a flawed agreement.<\/p>\n\n\n    <div class=\"my-7 lg:my-10 border-y-2 border-gray-100 py-7 lg:py-10 flex flex-col sm:flex-row items-start gap-10\">\n                    <img decoding=\"async\" class=\"w-52 mx-auto my-0! rounded\" src=\"https:\/\/img.legalvision.com.au\/wp-content\/uploads\/sites\/4\/2023\/05\/03024102\/LegalVision_UK-Supplier-Contracts-Checklist.jpg\" alt=\"Front page of publication\"\n                 loading=\"lazy\" width=\"208\" height=\"298\">\n                <section>\n            <div class=\"text-2xl font-bold\">Supplier Contracts Checklist<\/div>\n            <div class=\"body-text\">\n                <p>Download this free Supplier Contracts Checklist to ensure your contracts will meet your business\u2019 needs.<\/p>\n            <\/div>\n            \n\n<a href=\"https:\/\/go.legalvision.co.uk\/supplier-contracts-checklist.html\" class=\" block px-5 py-3.5 max-w-fit bg-orange button__hover transition rounded text-white font-bold text-lg no-underline uppercase leading-tight text-center\" target=\"\" rel=\"\">Download Now<\/a>        <\/section>\n    <\/div>\n\n\n\n\n<h2 class=\"wp-block-heading\">Key Takeaways<\/h2>\n\n\n\n<p>If you have entered into a contract based on a mistake about a person\u2019s identity, a term of the contract, or a fact about the product you bought, you can use the law of \u2018mistake\u2019.

For a mistake to potentially void a contract, it must relate to a fundamental assumption on which the contract was based, and the mistake must have a material effect on the agreed-upon exchange. Courts are typically reluctant to interfere with commercial agreements unless there is clear and convincing evidence of a serious mistake that goes to the heart of the contract.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1737971312006\"><strong class=\"schema-faq-question\"><strong>How does the law of mistake differ from misrepresentation?<\/strong><\/strong> <p class=\"schema-faq-answer\">While both mistake and misrepresentation can affect the validity of a contract, they are distinct legal concepts. A mistake relates to a belief held by one or both parties at the time of contract formation, without any false statement being made. Misrepresentation, on the other hand, involves a false statement made by one party that induces the other to enter into the contract. The remedies available and the legal tests applied can differ between these two concepts.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1752217074356\"><strong class=\"schema-faq-question\">Can I claim a mistake if I did not read the contract carefully?\u00a0<\/strong> <p class=\"schema-faq-answer\">Usually not. Under UK law, you are expected to take reasonable care before signing a contract. If you had the opportunity to review the contract but did not, or you misread it, you cannot normally rely on the mistake to void it. Exceptions may arise if the other party misled you or if the mistake concerned a critical term that was unclear or left out.\u00a0<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1752217114049\"><strong class=\"schema-faq-question\">How long do I have to claim a mistake?\u00a0\u00a0<\/strong> <p class=\"schema-faq-answer\">You have a limited time window to challenge a contract due to an error. Under UK law, you generally have up to 6 years from when the contract was made to bring a claim. However, there is no set deadline for when you must act after discovering the mistake, but you must act quickly. If you wait too long, you may lose the right to bring a claim. Additionally, if you continue to perform your obligations under the contract after discovering the mistake, it could be perceived as an acceptance of it, which could prevent you from challenging it later.<\/p> <\/div> <\/div>\n<div class=\"not-prose m-feedback-prompt\">\n    <!-- Thumbs up\/down bar -->\n    <div class=\"m-feedback-prompt__main\">\n        <div class=\"m-feedback-prompt__title\">Was this article helpful?<\/div>\n        <div>\n            <!--span class=\"m-feedback-prompt__button--text\">Thanks!<\/span-->\n            <button type=\"button\" class=\"m-feedback-prompt__button m-feedback-prompt__button--yes\"\n                    data-analytics-link=\"feedback-prompt:yes\" aria-label=\"Agree\">\n                <i class=\"fa-regular fa-thumbs-up fa-3x\"><\/i>\n            <\/button>\n            <button type=\"button\" class=\"m-feedback-prompt__button m-feedback-prompt__button--no\"\n                    data-analytics-link=\"feedback-prompt:no\" aria-label=\"Disagree\">\n                <i class=\"fa-regular fa-thumbs-down fa-3x\"><\/i>\n            <\/button>\n        <\/div>\n    <\/div>\n\n    <!-- Feedback form -->\n    <div class=\"m-feedback-prompt__form\">\n        <div class=\"m-feedback-prompt__form--thanks \">\n            <div>Thanks!<\/div>\n            <p>\n                We appreciate your feedback \u2013 your submission has been successfully received.            <\/p>\n        <\/div>\n        <form id=\"contact-form\" class=\"m-feedback-prompt__form--form\" action=\"\" method=\"post\">\n            <input type=\"hidden\" id=\"authenticity_token\" name=\"authenticity_token\" value=\"488c9024c8\" \/><input type=\"hidden\" name=\"_wp_http_referer\" value=\"\/api\/wp\/v2\/posts\/2271\" \/>            <input value=\"https:\/\/legalvision.co.uk\/commercial-contracts\/mistake-in-contract-law\/\" type=\"hidden\" name=\"currenturl\"\n                   id=\"currenturl\">\n            <input value=\"What is a Mistake in Contract Law?\" type=\"hidden\" name=\"currenttitle\"\n                   id=\"currenttitle\">\n            <label>\n                <!-- display on thumbs-up -->\n                <span class=\"m-feedback-prompt__feedback m-feedback-prompt__feedback--yes\">\n                    Can you tell us <span class=\"font-semibold\">why<\/span> you found it helpful?\n                <\/span>\n\n                <!-- display on thumbs-down -->\n                <span class=\"m-feedback-prompt__feedback m-feedback-prompt__feedback--no text-lg\">\n                    How can we better improve this article?\n                <\/span>\n                <textarea name=\"feedbackmessage\" id=\"feedbackmessage\" required><\/textarea>\n            <\/label>\n\n            <div class=\"m-feedback-prompt__form--error\" id=\"form-submit-error\"><\/div>\n            <button id=\"submit-contact-form-button\" type=\"submit\" name=\"commit\" class=\"m-feedback-prompt__form--submit\"\n                    data-analytics-link=\"feedback-prompt:submit\">\n                Submit            <\/button>\n        <\/form>\n    <\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>If you run a business, you will likely enter into contracts often.
