Acquiescence means tacit or passive approval; some kind of implied consent to an act (especially one that runs against your interest or general acceptable principle or standard of doing things). Such tacit approval of an act operates in law to offer a defence to the doer of such an act. In land law it operates to bar or stop someone from laying claim to his land occupied or taken over by another who has, e.g. taken steps to develop and expend money on the land while the owner is aware and does nothing about the intruder or trespasser occupying or expending money developing the land in a mistaken believe that he actually has a right to do so. If such rightful owner later comes to lay claim to the already developed land that he encouraged its development by another, he will be barred or stopped from claiming such right of ownership. In that way, a prescriptive title will inure (arise) in favour of the condoned trespasser. Mohammed V. Mohammed (2012) All FWLR (Pt. 655) 363 C.A at p.367; Adejumo & Ors. V.
