Types of Contract

1. Voidable Contract: An agreement which is enforceable by law at the option of one or more of the parties thereto, but not at the option of the other or others, is a voidable contract. A contract is voidable when one of the parties to the contract has not exercised his free consent. One of the essential elements of a formation of a contract for example, free consent, is absent. All voidable contracts are those which are induced by coercion fraud or misrepresentation. The person whose consent is not freely given may avoid a contract. It therefore continues to be valid till the party whose consent is caused by coercion, undue influence, fraud or misrepresentation choose to avoid the contract within a reasonable time. Contract then is not binding on the other party.
2. Void Contract: A contract which ceases to be enforceable by law becomes void, when it ceases to be enforceable. A void contract is a nullity from its inception. No rights accrue there under. A contract may also be originally valid when entered into but subsequently due to change in the events or circumstances, it may become void. It should be noted that there cannot be a void contract because when the contract is void, it is no contract at all. The right expression therefore is void agreement and not void contract.
3. Unenforceable Contract: A contract which cannot be enforced is a valid contract in law, but is incapable of proof, and therefore cannot be enforced in the Court of Law.
4. Executed Contract: Where both the parties have performed their obligation, it is an executed contract. Even when one party to the contract has performed his share of the obligation, the contract is executed though to the other party is still under an outstanding obligation to perform his part of the promise.
5. Executory Contract: Here neither party to the contract has performed his share of the obligation, for example, both the parties have yet to perform their promises, the contract is executory. In an executed
