Frequent calls on the land by unknown people that are also trying to monitor any unwanted activities on the land when proper documents from the seller can not be gotten or unnecessary delay in getting the papers.

In Ekpoma, Edo State a friend was introduced into buying 2 plots of land, the purported owner's son actually colluded with the mother and other siblings to sell the Aunts' land though this land in question formerly belonged to their father, but he had long bequeathed the land to his sister. So without the knowledge of their father, they arranged for another man from Abia State to pose as their father and they carefully made sure when my friend and his client will be coming to pay the money in their father's house he must have left for the farm. So the elderly man from Abia State was introduced as the father, money exchanged hands that very day, and the eldest of the siblings took the money to finance his relocation abroad. My friend's client have to pay again to the man's sister before he could finally secure the land, the woman came up later to lay claim to the land. Assuming these people did not pay at once but paid an unscheduled visit to meet the same old man in the house, they would have stumbled on the fact, because the Abia man only came once to do the job, while the father was not around.
