a letter of indemnity loi is a document that guarantees certain provisions will be met between two parties to a contract or compensation will be provided these letters promise to make one or more parties to a contract whole again if a contractual obligation doesn t end up being fulfilled for instance in finance lois can be used to protect against losses from lapses in security documentation or procedure banks or insurance companies issue lois to cover parties against financial losses from a breach of contract these offer contracting parties some protection and greater ease when entering a transaction knowing they will be covered should there be any losses from another party s failure to fulfill the contract 
the chief role of an loi is to ensure that one or more parties to a contract won t take on losses if another party doesn t fulfill their part lois can be provided by a third party who insures the contract and assumes responsibility for any financial losses or damage the loi shields against liability ensuring that the parties will be held harmless even if there is a breach of contract indemnity refers to the full amount of compensation you would need to recover as a legal term indemnity also describes an exemption from liability a letter of indemnity provides immunity from liability for one or both parties in a contract with a third party often agreeing to indemnify against the potential losses understanding loislois state that any damage caused to a contracting party is the responsibility of the other party or a third party to the contractual agreement 1 for this reason lois also called indemnity bonds or bonds of indemnity are like insurance policies known as indemnity insurance lois are used in various types of business transactions in cases where items of value are transported by moving companies or delivery services lois ensure that the party that owns the valuables will be compensated if the possessions are lost damaged or stolen during transport lois are generally signed when the valuable items are presented to the shipping company and before a bill of lading which is a document issued by a carrier acknowledging receipt of the cargo they are also used when a second party borrows something of value from the first party such as a car or a power tool in this case the person borrowing the car or power tool can protect themselves with a letter of indemnity this would typically mean a third party such as an insurance firm takes financial responsibility for any losses or damage that might result from using the car or tool lois should always be signed by a witness when the assets involved are quite valuable it s preferable to have an insurance carrier representative a banker or another professional sign the document not just any available witness letters of indemnity should include the names and addresses of both parties involved plus the name and affiliation of the third party if any detailed descriptions of the items and intentions are also required as are the signatures of the parties and the date the contract is executed examples of loislet s say you hire professional painters for your house painters often carry insurance to protect themselves against injuries or damage from the job the painters can present an loi showing that an insurance company has accepted legal responsibility for their contractual obligations and has agreed to compensate you for any damage to your home in this situation lois protect painters and other contractors against any damage or inability to complete the job from your perspective as the homeowner the loi establishes that you won t pay for any problems that come about should the painters not be able to complete their part of the contract in finance an loi can be crucial in addressing unforeseen circumstances for example let s say you ve misplaced a physical stock certificate and can t find it you can approach the company that issued the stock and provide it with an loi that states that the stock certificate has been lost destroyed or stolen the letter would ask the company to issue a replacement certificate and state that should the original certificate resurface you would take full responsibility and indemnify the company against any loss or complications that might come about because it was found in this way the company guards against potential double claims on the same stock and you can get back your stock certificate more quickly
