Waiver \Waiv"er\, n. (Law)
   The act of waiving, or not insisting on, some right, claim,
   or privilege.
   [1913 Webster]
    

WAIVER., The relinquishment or refusal to accept of a right. 
     2. In practice it is required of every one to take advantage of his 
rights at a proper time and, neglecting to do so, will be considered as a 
waiver. If, for example, a defendant who has been misnamed in the writ and 
declaration, pleads over, he cannot afterwards take advantage of the error 
by pleading in abatement, for his plea amounts to a waiver. 
     3. In seeking for a remedy the party injured may, in some instances, 
waive a part of his right, and sue for another; for example, when the 
defendant has committed a trespass on the property of the plaintiff, by 
taking it away, and afterwards he sells it, the injured party may waive the 
trespass, and bring an action of assumpsit for the recovery of the money 
thus received by the defendant. 1 Chit. Pl. 90. 
     4. In contracts, if, after knowledge of a supposed fraud, surprise or 
mistake, a party performs the agreement in part, he will be considered as 
having waived the objection. 1 Bro. Parl. Cas. 289. 
     5. It is a rule of the civil law, consonant with reason, that any one 
may renounce or waive that which has been established in his favor: Regula 
est juris antique omnes licentiam habere his quae pro se introducta sunt, 
renunciare. Code 2, 3, 29. As to what will amount to a waiver of a 
forfeiture, see 1 Conn. R. 79; 7 Conn. R. 45; 1 Jo Cas. 125; 8 Pick. 292; 2 
N. H, Rep. 120 163; 14 Wend. 419; 1 Ham. R. 21. Vide Verdict.
