An investigation by the Nation found that the fraudsters then use the acquired title deeds to sell the land to unsuspecting investors.
Courts are now teeming with victims trying to repossess their land and to recover money paid for stolen land.
Land officials rank Kajiado, Kwale and Kilifi as the counties with the biggest problems of brazen theft of land.
Among the documents the fraudsters target are sale agreements, land transfer documents, title deeds, green card and share certificates where the property was acquired through a land-buying company.
The fraudsters also falsify wills, letters of administration of the estate, and letters of allotment.
