In Kayode v. Odutola (2001) 11 NWLR (Pt. 725) 659 at 684, D—F per Iguh JSC: ‘Accordingly, it has been said that if a stranger begins to build on another’s land supposing it to be his own and the real owner, perceiving his mistake, abstains from setting him right and leaves him to persevere in his error, a court of equity will not allow such real owner afterwards to assert his title to the land on which the stranger has expended money on the supposition that the land was his own. It considers that the owner saw the mistake into which the stranger had fallen and that it was the duty of such owner to be active and to assert his adverse title; and that it would be dishonest in the owner to remain wilfully passive on such an occasion, in order afterwards to profit by the mistake which such owner might have prevented. See Ramsden v. Dyson (1866) L.R.H.L. 129 at 140. One vital point has, however, been made.’
CONDUCT THAT WILL AMOUNT TO LACHES & ACQUIESCENCE
Equitable estoppel thus bears some relationship to the equitable doctrine of laches. The type of conduct that will amount to laches and acquiescence will be such that will be repugnant to equity and good conscience.
