Waiver

Waiver means, passing by of an occasion to enforce a legal right, whereby the right to enforce the same is lost.  A waiving or forsaking the assertion of a right at the proper opportunity.  The passing by of a thing, or a declining or refusal to accept it. A common instance of this is where a landlord waives a forfeiture of a lease by receiving rent or dis training for rent which has accrued due after the forfeiture. Sometimes it is applied to an estate or something conveyed to a man, and sometimes to a plea; and it is frequently applied to the declining to take advantage of an irregularity in legal proceedings.
