To repudiate a right is to express in a sufficient
manner, a determination not to accept it, when it is offered.
2. He who repudiates a right cannot by that act transfer it to another.
Repudiation differs from renunciation in this, that by the former he who
repudiates simply declares that he will not accept, while he who renounces a
right does so in favor of another. Renunciation is however sometimes used in
the sense of repudiation. See To Renounce; Renunciation; Wolff, Inst. 339.
