There are mainly four types of damages, such as
(i) Ordinary damages
(ii) Special damages
(iii) Vindictive or exemplary damages and
(iv) Nominal damages

According to the Limitation Act, 1963 a contract must be performed within a specified time. If it is not performed within this specified time limit and against which if no action is taken by the promisee in the Court of Law within, specified time, then the promisee is deprived of his remedy at law. In such cases, the contract is discharged.

The rule of impossibility of performance is based on the following maxims.
(i) The law does not recognize what is impossible and
(ii) What is impossible does not create an obligation.

Performance of contract is under two types namely, Actual Performance and Attempted Performance.

Discharge of contract implies termination of the contractual relationship between the parties. A contract is discharged if it ceases to operate and when the rights and obligations created by it come to an end.

(i) Waiver means "abandoning" the rights. When a party to the contract abandons or waives his rights the contract is discharged.
(ii) For Example: A promises to paint a picture for B. B afterwards forbids him to do so. A is no longer bound to perform the promise.

The term "Damage" means monetary compensation payable by the defaulting party to the aggrieved party in the event of the breach of a contract for the loss suffered by him.

Supervening impossibility may be :
(i) By some event beyond the control of the parties; or
(ii) By some act either of the promisor or of the promisee.

There are two types of impossibility of performance such as:
(i) Impossibility at the time of Agreement
(ii) Impossibility arising subsequent to the formation of contract.

The consent may be of the following types:
(i) Express Consent
(ii) Implied Consent
