Contracts classified according to formation

1. Express contract. An expresscontract is one entered into by words which may be either spoken or written. Where the proposal and acceptance is made in words, it is an express contract.




2. Implied contract. Where the proposal or acceptance is made otherwise than in words, it is an implied contract. Implied contract can be smelled out of the surrounding circumstances and the conduct of the parties who made them. So where a person employs another to do some work the law implies that the former agrees to pay the work.




3. Constructive or quasi-contract. It is contract in which there is no intention on either side to make a contract, but the law imposes a contract. In such a contract rights and obligations arise not by any agreement between the parties but by operation of law. Thus, a finder of lost goods is under an obligations to find out the true owner and return the goods. Similarly, where certain books are delivered  to a wrong addressee, the addressee is under an obligation either topay for them or return them.




4. E-Com Contracts/Contracts over Internet. These contracts are entered  into between the parties using internet. In electronic commerce, different parties/persons create network which are linked to other network through EDI (Electronic Data Inter-change) This helps in doing business transactions using electronic mode.
