Indemnity is often used as a synonym for compensation or reparation. All three can be construed as obligations to act on an injured party's behalf given the occurrence of a contractually-specified event. However, indemnity as a legal concept has a much broader meaning than the other two terms; namely, an indemnity is to make a party to a contract "whole" again should that contractually-specified event occur.
While the event may be specified by the contract, the actions that must be taken to make the injured party "whole" again are largely fact-based and unknown to the parties until the event occurs, while the maximum liability is often expressly limited by the contract.
A car insurance policy is an example of indemnification. If a purchaser of car insurance policy is involved in an accident wherein the liability for the accident is undisputedly of their insured driver, then the insurance carrier has the duty to indemnify their insured driver in very specific ways to "make them whole" again.
The insurance carrier may pay them compensation (recompense for lost wages that would have normally occurred), pay them for medical/legal/(pain and suffering) damages (i.e., those costs arising specifically as the result of the accident), reparations to tow and repair the vehicles involved in the accident returning them to their original condition, and the payment of rental vehicles while awaiting repairs.
It is in the breadth of the insurance carrier's obligations that we see the application of an indemnity; in other words, an indemnity is a "generalized promise of protection against a specific type of event by way of making the injured party whole again."
An indemnity should also be differentiated from a guarantee. A guarantee is the promise of a third party to honor the obligation of a party to a contract should that party be unable or unwilling to do so (usually a guarantee is limited to an obligation to pay a debt). This distinction between indemnity and guarantee was discussed as early as the eighteenth century in Birkmya v Darnell. In that case, concerned with a guarantee of payment for goods rather than payment of rent, the presiding judge explained that a guarantee effectively says "Let him have the goods; if he does not pay you, I will." 
Indemnity clauses 
Under section 4 of the Statute of Frauds (1677), a "guarantee" (an undertaking of secondary liability; to answer for another's default) must be evidenced in writing. No such formal requirement exists in respect of indemnities (involving the assumption of primary liability; to pay irrespective of another's default) which are enforceable even if made orally. (Ref: Peel E: "Treitel, The Law of Contract")
Contract award 
In England and Wales an "indemnity" monetary award may form part of rescission during an action of Restitutio in integrum. The property and funds are exchanged, but indemnity may be granted for costs necessarily incurred to the innocent party pursuant to the contract. The leading case is Whittington v Seale, in which a contaminated farm was sold. Due to the contract, buyers renovated the real estate and, due to the contamination, incurred medical expenses for their manager who had fallen ill. Once the contract was rescinded, the buyer could be indemnified for the cost of renovation as this was necessary to the contract, but not the medical expenses as the contract did not require them to hire a manager. Were the sellers at fault, damages would clearly be available.
The distinction between indemnity and damages is subtle, but they may be differentiated by considering the roots of the law of obligations. How can money be paid where the defendant is not at fault? The contract before rescission is voidable but not void, meaning that, for a period of time, there is a legal contract. During this time both parties have legal obligation. If the contract is to be voided ab initio the obligations performed must also be compensated. Therefore the costs of indemnity arise from the (transient and performed) obligations of the claimant rather than a Breach of obligation by the defendant.
Indemnity insurance compensates the beneficiaries of the policies for their actual economic losses, up to the limiting amount of the insurance policy. It generally requires the insured to prove the amount of its loss before it can recover. Recovery is limited to the amount of the provable loss even if the face amount of the policy is higher. This is in contrast to, for example, life insurance, where the amount of the beneficiary's economic loss is irrelevant. The death of the person whose life is insured for reasons not excluded from the policy obligate the insurer to pay the entire policy amount to the beneficiary.
Most business interruption insurance policies contain an Extended Period of Indemnity Endorsement, which extends coverage beyond the time that it takes to physically restore the property. This provision covers additional expenses that allow the business to return to prosperity and help the business restore revenues to pre-loss levels.
Freeing of slaves and indentured servants 
When the slaves of Zanzibar were freed in 1897, it was by compensation since the prevailing opinion was that the slave owners suffered the loss of an asset whenever a slave was freed.
In the 1860s in the United States, U.S. President Abraham Lincoln had requested many millions of dollars from Congress with which to compensate slave owners for the loss of their slaves. On July 9, 1868, Section IV of the Fourteenth Constitutional Amendment dismissed all of the claims that slave owners had been injured by the freeing of the slaves.
In 1807-08, in Prussia, statesman Baron Heinrich vom Stein introduced a series of reforms, the principal of which was the abolition of serfdom with indemnification to territorial lords.
Haiti was required to pay an indemnity of 150,000,000 francs to France in order to atone for the loss suffered by the French slave owners.
Costs of war 
The nation that wins a war may insist on being paid compensations for the costs of the war, even after having been the instigator of the war.
- Following the Sino-Japanese War of 1894-95, the Treaty of Shimonoseki required that China pay Japan the sum of 200,000,000 taels (or liangs).
- China incurred an indemnity which resulted from massacres of foreigners during the Boxer Rebellion. The payment of 450,000,000 Haikwan taels, or $330,000,000 became necessary.
