Acquiescence

Acquiescence is the name applied to an important principle of equity in the law of both England and Scotland. It means either (1) the failure for a length of time to take an objection, of which the party is aware, to an invalid or challengeable agreement, or a set of accounts; or (2) the failure to object to any important proceeding by another person, involving expense and difficulty of restoration, in such circumstances that it is fair to conclude that the person failing to object has tacitly agreed to his property or other rights being dealt with. Acquiescence closely resembles the Scottish doctrine of rei intervenutus in the law of contracts, and also to some extent the doctrine of estoppel by conduct in the law of England.
