A waiver also called a release form is a legal document that contains an agreement between two parties. It is an essential document which informs participants of the risks that are involved in certain activities and protects the parties involved from liability.
The first party is the releasor which is the person promising not to sue and the second party is the releasee which is the party that is reliable. After the form is signed, the first party which is the releasor accepts that the risk involved is understood and also promises not to sue the releasee in case there are damages caused.
