Under the Madhya Pradesh Land Revenue Code, 1959, a well-defined hierarchy of 'Revenue Officers' is established to administer land revenue, maintain land records, and adjudicate land-related disputes. These officers are crucial for the efficient functioning of the land administration system. The classes of Revenue Officers, in descending order of authority, generally include:

1. Board of Revenue: This is the highest revenue court and appellate authority in the state, exercising superintendence over all revenue officers and courts.
2. Commissioner: Heads a revenue division, overseeing the Collectors within that division.
3. Collector: The chief officer of a district, responsible for land revenue administration, maintenance of law and order, and overall district administration. The Collector also functions as the District Magistrate.
4. Additional Collector: Exercises powers of the Collector as delegated by the State Government or the Collector.
5. Joint Collector: Similar to Additional Collector, exercising delegated powers.
6. Deputy Collector: Assists the Collector in various revenue functions.
7. Assistant Collector: Junior officers who perform duties as assigned by the Collector.
8. Sub-Divisional Officer (SDO): Heads a sub-division within a district, responsible for revenue administration and law and order in their jurisdiction. They exercise many powers of the Collector within their sub-division.
9. Tehsildar: The chief revenue officer of a tehsil (or taluka), responsible for land records, revenue collection, and adjudication of minor land disputes at the tehsil level.
10. Additional Tehsildar: Assists the Tehsildar and exercises powers as delegated.
11. Naib Tehsildar: A junior revenue officer assisting the Tehsildar, often in charge of a specific part of the tehsil.
12. Superintendent of Land Records: Responsible for the maintenance and supervision of land records at the district level.
13. Assistant Superintendent of Land Records: Assists the Superintendent of Land Records.
14. Revenue Inspector (RI): Supervises the work of Patwaris in a circle (group of villages).
15. Patwari: The lowest but most crucial revenue officer, responsible for maintaining village land records, crop inspections, and assisting in revenue collection at the village level.

Each class of officer has specific powers and duties defined by the Code, ranging from maintaining village records to hearing appeals and revisions in land revenue matters.
