Damages
Typically, the remedy for breach of contract is an award of money damages. Courts usually adopt one of three ways of calculating the value of damages.
The most common is to assess the sum which would restore the injured party to the economic position that he or she expected from performance of the promise or promises (known as an " expectation measure " or "benefit-of-the-bargain" measure of damages).
When it is either not possible or desirable to award damages measured in that way, a court may award money damages designed to restore the injured party to the economic position that he or she had occupied at the time the contract was entered (known as the "reliance measure"), or designed to prevent the breaching party from being unjustly enriched (" restitution ").
Specific Performance
There may be circumstances in which it would be unjust to permit the defaulting party simply to buy out the injured party with damages. For example where an art collector purchases a rare painting and the vendor refuses to deliver, the collector's damages would be equal to the sum paid.
The court may make an order of what is called " specific performance", requiring that the contract be performed.In some circumstances a court will order a party to perform his or her promise (an order of " specific performance") or issue an order, known as an "injunction," that a party refrain from doing something that would breach the contract.
Both an order for specific performance or an injunction are discretionary remedies, originating for the most part in equity. Neither is available as of right and in most jurisdictions and most circumstances a court will not normally order specific performance.
