我想問咩係consideration?

hmm~ ok, when form a contract, you need to be consideration. 意思系你要念清楚所有有关的条款同埋你的能力。
Let said, u have to deal with a contract to buy a car. The agreement in the contract exist some rule, like the owner want you to pay him not less than $ 10000 each month, and you have to clear all balance within 24 months. So, all these rules you have to consider... so you get what i mean ?

Consideration is something that is done or promised in return for a contractual promise. For example, in a promise between A and B for the sale of A's car to B, B's payment of the price of the car (or promise to do so) is the consideration for A's promise. Consideration is a central concept in the common law of contracts. Under classical contract theory, consideration is required for a contract to be enforceable. Service contracts, and other contracts not governed by the Uniform Commercial Code, generally require consideration for a contract modification to be binding on the parties, because of the preexisting duty rule.
