A contract implied by law is also called quasi-contract because it is not actually a contract; Rather, it is a means for the courts to remedy situations in which a party is not guilty of an offence, but has a clear obligation to make a payment or to discharge a duty. Treated, in the simplest definition, a promise enforceable by law. The promise could be to do something or to do nothing. The performance of the contract requires the mutual agreement of two or more people, one of whom usually makes an offer and the other accepts. If one party does not keep the promise, the other party is entitled to an appeal. Contract law deals with issues such as the existence of a contract, what it means, the non-breakage of a contract and compensation for the victim. A tacit contract can be implied or implied. An implied contract is a contract in which the terms of the contract are so obvious that they do not need to be expressed orally. For example, by calling a doctor for a physical patient, a patient agreed that he is paying a fair price for the service. If he refuses to pay after examination, he has broken an implied contract.
The Treaty of Rome Act, as contained in the law books of the Byzantine emperor Justinian of the 6th century, reflected a long economic, social and legal evolution. It recognized different types of contracts and agreements, some of which were enforceable, others not. Much of the history of the law deals with the classifications and distinctions of Roman law. It was only during the last phase of development that Roman law generally implemented informal enforcement contracts, i.e. agreements to be concluded after they were obtained. This phase of development was lost with the disintegration of the Western Empire. When Western Europe migrated from an urbanized trading society to a localized agricultural society, Roman courts and administrators were replaced by relatively weak and imperfect institutions. The principles underlying a tacit contract are that no person should receive unfair benefits at the expense of another person and that no written or oral agreement is required to obtain fair play.
