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. Some activities are considered inherently dangerous, and those who participate in such activities may be required to sign a release form, acknowledging that they are assuming the responsibility for their voluntary participation in such activities. The release acts as an assurance to the person requesting the release that they will not be subjected to litigation resulting from the signing party's informed and consensual acts. It may be a condition to the acceptance of benefits in settling a claim, in which the person receiving the benefit agrees that person making the settlement has fully carried out their duties in regard to the claim and will not be liable for any further benefits. A waiver is the intentional and voluntary giving up of something. A waiver may be made by an express statement or by conduct, such as not enforcing a right. Some activities require a waiver of liability from participants, especially in dangerous activities such as scuba diving or car racing.
