/juːnɪˈlætərəl kɒntrækt/ – Pharse
Definition: hợp đồng đơn phương.
A more thorough explanation: A unilateral contract is a type of contract in which one party makes a promise or undertakes an obligation without receiving a reciprocal promise or obligation from the other party. In a unilateral contract, one party is bound to perform their promise or obligation once the other party has completed a specified act or condition.
Example: “I promise to pay you $100 if you find my lost cat.” In this example, the person offering the reward is making a unilateral promise. The person who finds the cat accepts the offer by performing the requested action (finding the cat).
