In contract law, an indemnity is a contractual obligation of one party (the indemnitor) to compensate the loss incurred by another party (the indemnitee) due to the relevant acts of the indemnitor or any other party. The duty to indemnify is usually, but not always, coextensive with the contractual duty to "hold harmless" or "save harmless". In contrast, a "guarantee" is an obligation of one party (the guarantor) to another party to perform the promise of a relevant other party if that other party defaults. Indemnities form the basis of many insurance contracts; for example, a car owner may purchase different kinds of insurance as an indemnity for various kinds of loss arising from operation of the car, such as damage to the car itself, or medical expenses following an accident. In an agency context, a principal may be obligated to indemnify their agent for liabilities incurred while carrying out responsibilities under the relationship. While the events giving rise to an indemnity may be specified by contract, the actions that must be taken to compensate the injured party are largely unpredictable, and the maximum compensation is often expressly limited. English common law 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. Under current English law, indemnities must be clearly and precisely worded in the contract in order to be enforceable. The Unfair Contract Terms Act 1977 stated that a consumer cannot be made to unreasonably indemnify another for their breach of contract or negligence, though this section was repealed by the Consumer Rights Act 2015 schedule 4 paragraph 6. 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-Hayne, in which a contaminated farm was sold. The contract made the buyers renovate the real estate and, 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 Once the contract was rescinded, the buyer could be indemnified for the cost
