If the language used by the parties to reach an agreement is so vague and imprecise that a reliable interpretation of contractual intentions is prevented, it is unlikely that there will be a contract. Contracts can be bilateral or unilateral. A bilateral treaty is an agreement by which each party makes a promise or a number of commitments. For example, in a contract for the sale of a home that promises the buyer to pay the seller $200,000 in exchange for the seller`s commitment to deliver the property of the property. These joint contracts take place in the daily flow of commercial transactions and, in cases where demanding or costly precedent requirements are requirements that must be met in order for the treaty to be respected. 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.
The doctrine determines whether a court should consider that the parties want the agreement to be enforceable by law, and it is established that an agreement is legally enforceable only if the parties believe that it intends to enter into a binding contract. In order to reach agreement on what has been agreed and to conclude a contract, the parties must agree on this point: in general, the parties are an integral part of a contract; offer, acceptance, intention to create legal relationships, consideration and legitimacy of form and content. The parties must have the intention that the offer and acceptance be legally binding on them: the “contractual will”. As a general rule, courts are not in a position to balance the “proportionality” of the consideration, provided that the consideration is determined as “sufficient”, the adequacy being defined as an exercise in legal review, while “adequacy” is subjective fairness or equivalence. For example, consent to the sale of a car for a pfennig may constitute a binding contract (although the transaction is an attempt to avoid taxes, it is treated by the tax authorities as if a market price had been paid).  Parties may do so for tax purposes and attempt to conceal donations in the form of contracts.
