Renunciation or abandonment of a right, whereby right is lost, extinguished and may be either expressed or implied. A waiver is an intentional relinquishment of such right. There can be no waiver unless the person against whom the waiver is claimed has full knowledge of his rights and of facts which would enable him to take effectual action for the enforcement of such rights. No one can acquiesce in a wrong while ignorant that it has been committed and the effect of his action will be to confirm it.
