/ɪˈliːɡəl kənˌsɪdəˈreɪʃən/ – Phrase
Definition: việc đối ứng trái phép.
A more thorough explanation: Illegal consideration refers to a promise, act, or forbearance that is offered or exchanged in a contract in violation of the law. This means that the consideration being offered is against the law or public policy, and therefore renders the contract unenforceable.
Example: The contract was deemed unenforceable due to the presence of illegal consideration, as one party promised to pay the other in exchange for committing a criminal act.
