To illustrate the fact that an owner built a house on Alicia`s land. However, the builder signed a contract with Bobby, who claimed to be Alicia`s agent, but in reality not. Although there is no binding contract between Alicia and the builder, most courts would allow the manufacturer to recover the costs of Alicia`s services and materials in order to avoid an unfair result. A court would achieve this by creating a fictitious agreement between the builder and Alicia, and by holding Alicia responsible for the cost of the contractor`s services and materials. The form of action known as indebitatus assumpsit has come to include various subforms known as the common money account. The most important of them included for the further development of the quasi-contract law: (i) the lawsuits for money had and obtained on the plaintiff`s use; (ii) the actions relating to the money to be made available to the defendant; iii) quantum meruit; and (iv) quantum talbat.  “Quasi-contracts” are also referred to as “implicit fine contracts” or “constructive contracts.” Since the parties have not entered into an explicit contract or implied contract, the quasi-contract is designed by a judge to remedy an unfair situation, regardless of the intent of the parties. The treaty is intended to prevent one party from profiting financially from the situation at the expense of the other. Such agreements may be applied after the authorization of a party that provides goods or services, even if it is not necessary. Instead, the assumption generates payment expectations. Accordingly, liability for a quasi-contract will be carried out either to the extent of an individual`s enrichment or to an amount that the court may consider a reasonable amount to adequately remedy an undue result.
The parties may accept many obligations in an enforceable contract before the courts. They mean the term “unfair enrichment” referred to in quasi-contractual proceedings. This term refers to the person who received an undue benefit. It does not matter whether he or she benefited from this advantage by chance or as a result of the misfortune of another. On the other hand, a quasi-contract is created only to the extent that it is necessary to remedy an unjustified situation. The quasi-contract is strictly established to the extent that it is necessary to avoid a situation of unjust enrichment, while an implied contract may give rise to various obligations that one person may demand from the other. Even if you don`t have a contract with your neighbour, the court may involve a contract between you and your neighbour that requires them to pay you or pay you the value of the pizza.
