Function Of Agreement
Contract law is based on the principle of pacta sunt servanda formulated in indenkisch („Agreements must be respected“).  The Common Law of Contract was born out of the now-disbanded letter of the assumption, which was originally an unlawful act based on trust.  Contract law is a matter of common law of duties, as well as misappropriation and undue restitution.  In the absence of contracts, it would be difficult for companies to conduct transactions. Companies are only willing to enter into agreements because they have confidence that existing contract law has provided legal guarantees that the assets traded will not be threatened if the obligations are not met. Indeed, these commitments, as well as the details of what will happen if a party does not respect its side of the good deal, constitute the backbone of most treaties. If a contract is contrary to an illegal purpose or a public order, it is cancelled. In the Canadian case of the Royal Bank of Canada v. Newell, a woman falsified her husband`s signature and her husband agreed to assume „all responsibilities and responsibilities“ for the falsified controls. The agreement was unenforceable, however, as it was intended to „stifle criminal prosecution“ and the bank was forced to make the man`s payments. Of these elements are the first two, supply and acceptance, the most important and form the basis of the presence of the other conditions. From the first days of the contracts, the agreement proved legally binding by the presence of the legal seal of both parties on the document, hence the term „stamp of authorization“.
Today, only the signatures of both parties are required to validate a written contract. Creates a contract for a function that accepts a fixed number of arguments and returns either a fixed number of results or totally unspecified results (the latter, if one is indicated). If the contractual terms are uncertain or incomplete, the parties do not reach an agreement in the eyes of the law.  An agreement is not a contract and the inability to agree on key issues that may include price or security elements may lead to the failure of the entire contract.
