Core Legal Answer & Context: Section 106 of the Transfer of Property Act, 1882, provides for the duration of leases when there is no specific contract, local law, or usage to the contrary. It distinguishes between two categories: a lease of immovable property for agricultural or manufacturing purposes is deemed to be a lease from year to year, terminable by six months' notice. A lease of immovable property for any other purpose is deemed to be a lease from month to month, terminable by fifteen days' notice. Given the general phrasing of the question, and considering the significance of agricultural leases in land law, 'year to year' is a valid statutory default for a specific, important category of immovable property leases.

Relevant Statutes and Sections: Transfer of Property Act, 1882, Section 106 (Duration of certain leases in absence of written contract or local usage).

Important Landmark Cases: Not applicable for a direct statutory provision.

Clear Conclusion: A lease of immoveable property shall be deemed to be year to year (if for agricultural or manufacturing purposes).
