A customer may be asked to sign a waiver, or separately, an indemnity. A customer may also be asked to sign a document containing both types of agreement.
A waiver is a contractual agreement that requires one party (usually the customer) to agree that it will not make any legal claim against the other party (the business), often in the context of the customer experiencing harm or injury while using the business’ service.
An indemnity is a further agreement by a party (the customer) that it will compensate the other party (the business) for any legal liability or loss sustained by the business, as a result of harm or injury suffered by the customer.
Examples of loss for which a business might ask for compensation include the cost of any medical assistance they arrange for the customer, damages for harm to its reputation, or where there is disruption to the business due to the customer’s injury, a business may ask for compensation for the profits it would have made if not for the disruption.
