One party receives only what the other party was already required to do. As a general rule, in order to be enforceable, a contract must contain the following elements: to meet the requirements of the law, the letter must normally identify the contracting parties, write the subject matter of the contract in such a way that it can be reasonably identified and constitute the essential conditions of the agreement between the parties. Even without taking into account the status of fraud, it is good to reduce the main contractual conditions to a signed and written agreement. Even if a fraud status does not apply to an oral contract, it can be very difficult to prove and enforce the contract without written agreement. In certain circumstances, a tacit contract may be established. A contract is in fact implied when the circumstances imply that the parties have reached an agreement when they have not done so explicitly. For example, John Smith, a former lawyer, may implicitly enter into a contract by going to a doctor and being examined; If the patient refuses to pay after the examination, the patient has breached a truly implied contract. A contract that is implicit in the law is also called a quasi-contract, since it is not, in reality, a contract; Rather, it is a means for the courts to remedy situations in which one party would be unduly enriched if it were not required to compensate the other. Quantum meriduit claims are an example of this. However, in certain circumstances, certain commitments that are not considered contracts may be applied to a limited extent. If, to its detriment, a party has relied in reasonable confidence on the assurances/promises of the other party, the court may apply an appropriate doctrine of not guilty in order to grant damage of trust to the non-injurious party in order to compensate the party for the amount resulting from the party`s reasonable confidence in the agreement.
To be enforceable, a contract must not be contrary to public policy. But public policies can be postponed. Traditionally, many States refused to pay gambling debts that had emerged in other jurisdictions for reasons of public policy. However, as more and more states have allowed gambling within their own borders, this policy has been largely abandoned and gambling debts of legal companies are now generally enforceable. . . .
