A release gives up a right, such as releasing one from his/her liability for harm or damage that may occur from performing under a contract, or participating in an activity. A release acts as some assurance to the person requesting the release that he/she will not be subjected to litigation resulting from the person giving the release. The term waiver is sometimes used to refer a document that is signed before any damages actually occur. A release is sometimes used to refer a document that is executed after an injury has occurred.
A hold harmless agreement is one in which one person agrees to assume the liability and risk that may arise from the obligation, and protects and indemnifies the other party against having to bear any loss. It may be used along with an acknowledgement of risk form. An indemnification or hold harmless clause may be included so the other party to the contract is reimbursed against loss or damage should a legal dispute ensue with respect to the contract or agreement.
A bailment is the act of placing property in the custody and control of another, usually by agreement in which the holder (bailee) is responsible for the safekeeping and return of the property.
