Contractual terms are fundamental to the agreement. If the contractual conditions are not met, it is possible to terminate the contract and claim damages. Unlike the wrongful act and unjust enrichment, the treaty is generally considered to be part of the Obligations Act that deals with voluntary obligations and, therefore, ensuring that only the good business to which the persons have consented is enforced by the courts is a high priority. While it is not always clear when people have really accepted the subjective sense of the word, English law considers that if a person objectively manifests his consent to a good deal, he is bound.  However, not all agreements are considered enforceable, even if they are relatively materially safe. There is a rebuttable presumption that people do not want legal application of agreements in the social or national sphere. The general rule is that contracts do not require a mandatory form, such as.B. in writing, unless required by law, usually for large companies such as the sale of land.  In addition, unlike civil regimes, the English common law has a general requirement that, in order to enforce an agreement, all parties must have brought something valuable or „matching“ into the bargain. This old rule is full of exceptions, especially where people wanted to change their agreements through jurisprudence and the just doctrine of sola change. In addition, the Legal Reform of the Contract (Rights of Third Parties) Act 1999 allows third parties to obtain the benefit of an agreement that they did not necessarily pay until the original parties have accepted the opportunity to do so. The general right to the exercise of the contract is a rule of non-compliance, as it limits the application of an agreement to those who have considered an agreement.
In an early case, Tweddle v Atkinson, it was found that a son, because he had ignored his father`s promise to pay $200 to his father, could not keep the promise.  Given the principle that the exercise of the duty should take into account the responsible person who has a legitimate interest in their performance, a 1996 report by the 1996 Legal Commission, Privity of Contracts: Contracts for the Benefit of Third Parties, recommended that, while allowing the courts the freedom to develop the common law, some of the blatant unfairness should be eliminated.  This gave rise to the Third Party Rights Act in 1999. Under Section 1, a third party may impose an agreement if it purports to grant a benefit to the third party, either individually or to a member as a class, and if there is no express provision that the person did not intend to apply it.  In this regard, the party that asserts that the execution is not contemplated by a third party places a heavy burden.  A third party has the same remedies as a person who enters into an agreement and can impose both positive benefits and liability limitations such as an exclusion clause.  The rights of a third party can only be revoked or revoked without their consent if it is reasonably likely that they will use them.  The royal courts, merged by Magna Carta in 1215 in London, accepted claims for „transgression of the case“ (now more of a misdemeanor). A jury was convened, and there was no need for trial, but there was a need to argue for a certain breach of the royal peace. Gradually, the courts admitted claims for which there had been no real difficulties, no unlawful act of „armed violence“ (vi and armis), but it was still necessary to enter it in the plea. Simon de Rattlesdene thus claimed in 1317 that he had been sold a wine contaminated with salt water and that, quite fictitiously, it had to be done „by force and weapons, namely with swords, arrows and arrows.“  The Court of Chancery and King`s Bench slowly began to admit the claims without the fictitious charge of violence and weapons dating back to 1350.
