Core Legal Answer & Context: The M.P. Land Revenue Code, 1959, includes protective provisions for Bhumiswamis, particularly concerning usufructuary mortgages, where possession of the land is transferred to the mortgagee. To prevent long-term alienation and ensure the Bhumiswami can regain their land within a reasonable period, Section 165(4) of the Code imposes a specific time limit on the validity of such mortgages. If the period exceeds this limit, the mortgage is deemed invalid.

Relevant Statutes and Sections: M.P. Land Revenue Code, 1959, Section 165(4) (Restrictions on usufructuary mortgages).

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

Clear Conclusion: No usufructuary mortgage shall be valid if it is for a period exceeding 6 years.
