Online agreements must be legally binding in order to enforce rules, protect privacy, avoid liability and inform users of what you expect. Implicit contracts can be considered binding and enforced by a court if there are sufficient facts to support a legal contract. It is the responsibility of a court to enforce binding contracts and to sanction one of the parties who violates the clauses they contain. A few days ago, a virus attacked Catso`s network, damaging 10 of its computers. In accordance with the agreement with PC Solutions, they had to immediately deliver an additional 10pc, but they did not do so in 2 days and it was an obvious breach in their contract. Catso told the superiors of PC Solutions and they quickly resolved the case to avoid a catso lawsuit. Such an action will be very damaging for PC Solutions, as the contract is binding because of its nature. Another important element of a binding agreement is that both parties intend to have legal consequences. Each contracting party must indicate that it recognizes that it is legally obedous to follow the contract and that the contract can be legally enforced. If the parties acknowledge that the agreement is legally binding, the contract is not obliged to expressly state it. On the other hand, if the parties do not want to be bound by a contract, they must ensure that the contract clearly expresses that wish. In this article, we define the concepts in a binding and non-binding way and discuss how legal documents can differ from each other.
