You can vary the term of a subsisting lease through a variation deed made between the landlord (lessor) and yourself (lessee).
Reach a consensus with the lessor on variation of the term of the lease.
Prepare and sign a variation deed showing the changes made.
If the lease was granted by a public body, make an application to them by letter for variation of the lease.
The public body then communicates to the KCCA Directorate of Physical Planning to approve the user clause.
After this, a variation deed is made.
The variation must be approved by KCCA.
If the term of the lease has been altered, then it should be crossed out from the title and the new term inserted.
This variation should be registered and the deed then attached to the title.
