Indemnity

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.

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 replaced by section 65 of the Consumer Rights Act 2015.

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 Once the contract was rescinded, the buyer could be indemnified for the cost of renovation as this was necessary to the contract, but not the medical expenses as the contract did not require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 and may be differentiated by considering the roots of the law of obligations: how can money be paid if the defendant is not at fault? The contract before rescission is voidable but not void, so, for a period of time, there is a legal contract. During that 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.

An indemnity is distinct from a guarantee, which 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 Birkmyr 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."

An indemnity is distinct from a warranty in that:
