A release made in ignorance of the existence of a claim is void as to such claim.1 A mistake of the parties as to the actual extent of injuries, or a misrepresentation by the agent of the party who has caused such injury, is ground for avoiding a release of damages arising from such specific injuries.2 On the other hand, if the parties intend that the release shall cover all rights of action, the fact that they did not know all the facts which determined the nature and value of such right, does not render the release invalid.3 Conversely, if a car of fruit is damaged, and the carrier settles therefor, thinking that the car was injured in an accident, he can not avoid the settlement on discovering that the car was only delayed thereby, and damaged by such delay.4
