Just before the expiry of your lease make sure you write a letter to the Commissioner of Lands informing him that you are the current holder of the lease and you are requesting for its renewal. You also must undertake to pay the charges attributable to the renewal.
The letter will be filed at records and a request dispatched to the land officer of the respective land registry where the Certificate of Lease was issued. This marks the start of a ka-process that involves several officer within the registry. After the request goes through a host of officers it ends up at the Commissioner who ideally will approve the renewal.
Take note of the special conditions that are on the initial lease and they needed to have been met before for ease of renewal. In fact, failure to meet those conditions may constitute reasonable grounds to deny you the renewal. Ideally in the case some of the conditions are no met, you’ll receive some correspondence to that effect though in Kenya it is hard for you to be deny the renewal. Make sure you pay all accrued rent and rates.
By the way, failure to seek renewal may be construed to mean that you are no longer interest in the said land whereupon another person can be issued with another lease for the same land. By the way, there are sharks in town on the prowl for expired lease whose owners have not renewed.
