lawyer:
If your buying property from a traditional family or omonile as they are called, its almost impossible to stop them. But there is a way i do it. After negotiating for the land on your behalf and they tell me their price and we come to a conclusion, we factor the price the omoniles are demanding and add it to the purchase price and commit them to sign as witness to the deed of assignment. That commitment irrevocably places a burden on them and their assignees to leave you alone when you are erecting structures and if you intend to sell that property to another person i future. Usually it could be in another form of agreement called a deed of ratification to be signed and honored by them that they ratified this sale in exchange for so so so amount of Naira and your home and dry.
It s a tough process which requires skill and knowledge of the modus operandi of the omoniles of that community but once it is in a paper form, they are finally hooked and commited. It is a problem that occurs in most communities that are being controled by omoniles and you cant find such in civilized areas.
Cheers!
good one lawyer.
but in real terms, this is a documentary solution that can only be effective with judicial assistance.but these omoniles are so crude and very far from the civil and developed society to understand the implications of documentary evidence.
adding to your postulation which is in fact not materially different from what i do, i would further advise that the purchaser must be ready to start erecting structures immediately.this is the only way you can effectively keep the omoniles at bare.
if you don't, then be ready to renegotiate, or reach out for judicial assistance.
