A waiver or 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. Courts vary in their approach to releases depending on the particular facts of each case, the releases' effect on other statutes and laws, and the courts' views of the benefits of releases as a matter of public policy.
