What is contract cancellation?
Cancellation of a contract is a situation in which one of the parties to a contract wishes to terminate the engagement with the other party. Cancellation of a contract cannot be carried out for any reason but only in accordance with the provisions of the agreement itself, the provisions of the Contract Law which determine in which situations and when a contract can be cancelled, or in a situation in which the other party has breached the contract. Cancellation for any other reason can constitute Breach of contract and grounds for filing a lawsuit.
Canceling a contract when there is no legal right to cancel can cause significant damage to the other party, so it is very important to know the legal provisions regarding the right to cancel, otherwise you may quickly find yourself in court and dealing with Financial claim or Civil lawsuit With very high amounts, you are forced to invest a lot of time, and quite a bit of money that you will have to pay to lawyers to represent you in court. This article will help you avoid all of this.
Cancellation of a contract in accordance with the provisions of the contract itself
The parties to a contract are entitled to shape the provisions of the contract as they see fit, and therefore they are also entitled to establish agreed provisions regarding the cancellation of the contract. That is, the parties can determine when the contract will be cancelled and under what conditions.
It is important to understand that not every contract has specific provisions regarding the cancellation of the contract, and in such cases the provisions of the Contract Law will apply.

If the contract regulates the manner of its cancellation, and if the conditions for cancellation have indeed been met, the party who has received notice of the cancellation of the contract will have difficulty opposing the cancellation, even if he uses the services of a Contract Law Lawyer experienced.
Cancellation of a contract in accordance with the provisions of the Contracts Law
There are several grounds in contract law that allow you to demand cancellation of a contract. It is important to know these provisions because they may save you from entering into a contract on terms that are not favorable to you or paying cancellation fees that you do not necessarily have to pay.
Error – Section 14 of the Contracts Law
(a) A person who entered into a contract due to an error and it can be assumed that but for the error he would not have entered into the contract and the other party knew or should have known about it, may cancel the contract.
(on) If a person who entered into a contract due to a mistake and it can be assumed that but for the mistake he would not have entered into the contract and the other party did not know and should not have known about it, the court may, at the request of the party who made the mistake, cancel the contract, if it deems it just to do so; if it does so, the court may order the party who made the mistake to pay compensation for the damage caused to the other party due to the conclusion of the contract.
(third) mistake It is not a ground for cancellation of the contract under this section if the contract can be performed by correcting the error and the other party has announced, before the contract was cancelled, that he is willing to do so.
(d) "טעות", לענין סעיף זה וסעיף 15 – בין בעובדה ובין בחוק, להוציא טעות שאינה אלא בכדאיות העסקה.
Deception – Section 15 of the Contracts Law
מי שהתקשר בחוזה עקב טעות שהיא תוצאת הטעיה שהטעהו הצד השני או אחר מטעמו, רשאי לבטל את החוזה; לענין זה, "הטעיה" – לרבות אי-גילוין של עובדות אשר לפי דין, לפי נוהג או לפי הנסיבות היה על הצד השני לגלותן.
Coercion – Section 17 of the Contracts Law
A. A person who entered into a contract due to coercion imposed on him by the other party or someone else on his behalf, by force or threat, may cancel the contract.
B. A good faith warning about the exercise of a right does not constitute a threat for the purposes of this section.
Oppression – Section 18 of the Contracts Law
A person who entered into a contract due to the exploitation by the other party or someone else on his behalf of the contracting party's distress, mental or physical weakness, or inexperience, and the terms of the contract are unreasonably worse than what is customary, may cancel the contract.
Partial cancellation of a contract
There are situations in which the contract can be canceled only partially and not in its entirety. In this regard, Section 19 of the Contracts Law states as follows:
If the contract is separable into parts and the reason for cancellation concerns only one of its parts, only that part may be cancelled; however, if it can be assumed that the party entitled to cancel would not have entered into the contract but for the reason, he may cancel the said part or the entire contract.
פסיקת בית המשפט העליון מכירה באפשרות של ביטול חוזה באופן חלקי, אך מדגישה שמדובר רק בחוזה שניתן להפרדה לחלקים. בעניין זה נקבע בע"א 7379/18 הדר יצחקי נ' רון יצחקי (פסק דין מיום 18.12.2019), כך:
In addition, the respondents argued that even if the appellant's legal claim is accepted, at the end of the day the only remedy that can be granted to her is the cancellation of the entire settlement agreement, as opposed to the exclusion of the Galilee project from the waiver letter. There is substance in this claim, but not as a ground for outright dismissal but as a warning sign regarding the future of the claim. In the normal course of things, the ground of deception leads to the cancellation of the contract (Section 15 of the Contracts Law). אמנם יש אפשרות תיאורטית לביטול, אך היא תלויה בכך שהחוזה ניתן "להפרדה לחלקים" (Section 19 of the Contracts Law; Shalev and Tzemach, at pp. 457-451; there may also be other legal avenues that lead to similar results – see Friedman and Cohen, at pp. 659-655).

Is it possible to demand cancellation of a contract in every case of breach of contract?
A party who decides to breach the contract allows the other party to notify the cancellation of the contract. However, the law distinguishes between a fundamental breach of contract and a non-fundamental breach of contract.
סעיף 6 לחוק החוזים (תרופות בשל הפרת חוזה), תשל"א-1970 קובע מהי הפרה יסודית:
"הפרה יסודית" – הפרה שניתן להניח לגביה שאדם סביר לא היה מתקשר באותו חוזה אילו ראה מראש את ההפרה ותוצאותיה, או הפרה שהוסכם עליה בחוזה שתיחשב ליסודית; תניה גורפת בחוזה העושה הפרות להפרות יסודיות ללא הבחנה ביניהן, אין לה תוקף אלא אם היתה סבירה בעת כריתת החוזה.
סעיף 7 לחוק החוזים (תרופות בשל הפרת חוזה), תשל"א-1970 קובע את תנאי הביטול בעת הפרה יסודית והפרה שאינה יסודית. הסעיף קובע כך:
A. The injured party is entitled to cancel the contract if the breach of contract was fundamental.
B. If the breach of contract was not fundamental, the injured party is entitled to cancel the contract after first giving the violator an extension for its performance and the contract is not performed within a reasonable time after the extension was granted, unless in the circumstances of the case the cancellation of the contract was unjust; no claim will be made that the cancellation of the contract was unjust unless the violator objected to the cancellation within a reasonable time after the notice of cancellation was given.
C. If the contract is divided into parts and one of its parts is violated, a violation that constitutes a ground for the cancellation of that part, the injured party is entitled to cancel only the part that was violated; if the violation also constitutes a fundamental breach of the entire contract, the injured party is entitled to cancel the part that was violated or the entire contract.
Cancellation of a contract by means of a notice of cancellation of the contract
Cancellation of a contract must be carried out legally and this matter is regulated in Section 20 of the Contracts Law, which states as follows:
The cancellation of the contract will be by notice to the other party by the contracting party within a reasonable time after he becomes aware of the reason for the cancellation, and in the case of duress – within a reasonable time after he becomes aware that the duress has ceased.
The logic in sending a notice regarding the cancellation of a contract is to inform the other party. It is not possible for you to decide to cancel the contract and the other party does not know this. The other party should not guess this.
בית המשפט העליון הדגיש את חשיבותה של הודעת הביטול וקבע שהחוזה יהיה בתוקף גם אם אחד הצדדים הפר אותו, כל עוד לא נשלחה הודעה בדבר ביטול הסכם. בעניין זה נקבע בע"א 1521/21 בלוגרין ווטר טקנולוג'יס אוריס חומרים מתקדמים (פסק דין מיום 8.3.2023) כך:
כידוע, הסעדים בגין הפרת חוזה מוסדרים, בעיקרם, בחוק החוזים (תרופות בשל הפרת חוזה), התשל"א-1970 (להלן: חוק התרופות). Contrary to what was determined in the preliminary ruling, the breach of a contract does not, in and of itself, result in the termination of the breached contract and the mutual cancellation of the obligations stipulated therein. In fact, the opposite is true. In the case of a breach of contract, the default is that the contract remains valid, and only if the conditions that allow the injured party to notify the cancellation of the contract are met (see: Section 7 of the Medicines Law), and if the injured party chooses to notify the cancellation of the contract (see: Section 2 of the Medicines Law), and does so in accordance with the conditions established in relation to the cancellation notice (see: Section 8 of the Medicines Law) – will the contract be canceled.
However, to the extent that the injured party is not interested in this, he is not entitled to it due to the non-existence of the conditions required for the cancellation of the contract; or if the injured party did not notify the breaching party of the cancellation of the contract in accordance with the outline set out in the Medicines Law - the contract will remain valid.
Result of contract cancellation
In every contract, one party gives something and the other party pays something in exchange for the product or service it receives. After the contract is canceled, the parties to the contract must return what each of them received under the contract. This matter is stipulated in Article 21 of the law, which states as follows:
When the contract is canceled, each party must return to the other party what he received under the contract, and if return was impossible or unreasonable – pay him the value of what he received.

In conclusion
Cancellation of a contract can be carried out in accordance with the provisions of the contract itself or in accordance with the provisions of the Contracts Law. Cancellation of a contract can be carried out in full or in part.
A contract can also be terminated following a breach of contract, but in these cases a distinction must be made between a fundamental breach and a non-fundamental breach. In the case of a non-fundamental breach, the violator must first be allowed to remedy the breach in order to avoid termination of the contract.
After the contract is canceled, the parties to the contract must return to each other what they received under the contract itself.
