Contracts are legal transactions established by the mutual and corresponding expressions of intent of the parties, which give rise to legal consequences and create a relationship of obligation between the parties. In accordance with the principle of freedom of contract, the parties may determine the content of the contract, provided that it does not contravene mandatory provisions of the law, public policy, personal rights or morality. However, the conditions under which the legal relationship arising from the formation of the contract will terminate are at least as important as the formation of the contract itself.
