Mutation is the official update of your land record when ownership changes. The Farmer Registry depends on it completely: the registry links you to land only if the land record shows you as an owner. So if you bought, inherited or were given land, the order is always the same: mutation first, Farmer Registry second.
This guide explains why, what happens to your Farm ID and Farmer ID after a mutation, and how to check that the change has reached the registry.
A registered sale deed, a will or a family agreement does not change the Farmer Registry. Only an updated land record does. That update is the mutation.
What mutation is
Every state keeps a record of rights (RoR) that shows who holds each piece of land. When ownership changes, the record must be updated. That update is called mutation, and has different local names: dakhil-kharij in Bihar, intkal in Haryana and Punjab, ferfar entries in Maharashtra, and namantaran in Madhya Pradesh.
Mutation is needed after:
- sale or purchase of land;
- inheritance after an owner’s death (succession mutation);
- gift or partition among family members;
- a court order or government allotment.
It is carried out by the state revenue department, usually through the tehsil or circle office, and in many states can be applied for online. For example:
- Bihar Bhumi offers online mutation applications and lets you “view online mutation status”;
- Haryana’s Jamabandi portal publishes the mutation register, which “indicates the changes that have to be brought about in ownership and title of the land”;
- Gujarat’s AnyROR shows the “135-D notice for mutation”, the notice issued before a change is recorded.
Why the Farmer Registry follows mutation
The Farmer Registry does not hold its own copy of who owns what. It is built on the state’s land record. The official AgriStack FAQ explains:
- The Farm ID (the ID for a piece of land) “is created as per ROR”, and “would have the CURRENT owner as per ROR”.
- “State RoR system shall maintain history of all the transactions happening on RoR along with farm id. Farmer registry would be synchronized with state RoR system using farm id and farmer id.”
- On ownership changes: “As and when these changes occur in ROR, they would get synchronized to farmer registry.”
So the registry is designed to follow the land record. If the land record is not updated, the registry cannot be either.

What happens if mutation is not done
The FAQ lists the common reasons land claims are rejected. Two of the four are mutation problems:
- “The owner has passed away, but the land records have not been updated (mutation has not occurred) and stand in name of dead person and not the farmer.”
- “The Record of Rights still stands in name of seller and not in the name of buyer-farmer.”
In both cases, the name match between your Aadhaar and the land record fails, because the record shows someone else.
Does the registry update automatically after mutation?
This is the most important question, and the honest answer is: it depends on your state.
The FAQ says that once land is claimed, “If any mutation occurs after the bucket has been claimed, such lands would automatically move from one farmer to another farmer under the farmer registry because the farmer registry is (As per State decision) connected electronically to the land record system.”
Notice the words “As per State decision”. Another answer in the FAQ adds that “Synchronization between state RoR system and state FR is critical and it can be configured based on the states requirement”. And on how exactly mutation affects Farm IDs, the FAQ (July 2024) says only that an “SOP will be shared describing scenarios where farm id gets affected”. We have not found that SOP published.
The FAQ also noted that Maharashtra had “enabled changes” to Farm IDs “which happen during Mutation”.
In practice:
| Your state | What to expect after mutation |
|---|---|
| Registry linked electronically to land records | Land should move to the new owner’s profile after the mutation is recorded |
| Not linked, or linked with delay | You may need to add the land yourself through the update option |
| Not sure | Check your profile after the mutation; ask your agriculture office |
Step by step: after you buy land
- Register the sale deed at the sub-registrar office, as required by law.
- Apply for mutation at the tehsil or circle office, or online where your state allows. In some states, mutation starts automatically after registration; ask.
- Track the mutation until it is approved, and get a copy of the updated land record.
- Check the land record shows your name, the right plot numbers and area.
- Check your Farmer Registry profile. If you already have a Farmer ID, see whether the land has appeared.
- Add the land if needed using the update option on your state portal (the national FAQ calls it the Update Farmer Request, or UFR). If you do not yet have a Farmer ID, register now and claim the land.
After you sell land
- The buyer applies for mutation, and the land record changes to their name.
- In states where the registry is synchronised, the plot should leave your profile.
- If it still appears after the mutation, tell your agriculture office or help desk. Keeping wrong land in your profile can cause problems if schemes or loans use it.
After inheritance
Succession mutation updates the record after an owner’s death. The FAQ says the deceased farmer’s Farmer ID “would be inactivated”, and the Farm ID “would now be linked to the successor”. If the heirs divide the land, “the farm ID will be inactivated and multiple farm IDs would be generated”. Full guide: inherited land and the Farmer Registry.
What changes and what does not

| Item | After a mutation |
|---|---|
| Your Farmer ID | Stays the same. It is linked to you through Aadhaar, not to any plot |
| Land linked to your Farmer ID | Changes: land you bought is added, land you sold is removed |
| Farm ID of a plot | Stays the same if the whole plot changes hands; new Farm IDs if the plot is divided |
| Enrolment number | Not affected; it was only for tracking your first registration |
Problems with the land record itself
Sometimes the mutation is done but the record still has mistakes: a misspelt name, a wrong area or a missing co-owner. These are corrected through the revenue department, not the Farmer Registry. Some states have online correction processes, such as Parimarjan in Bihar for correcting the digital jamabandi. Fix the record first; the registry will follow.
For CSC operators
- Before claiming land for a farmer who recently bought or inherited it, check the current land record. If it still shows the old owner, do not submit; explain the mutation step.
- For farmers who already have a Farmer ID, show them how to check their linked land after a mutation.
- Keep a list of your tehsil’s mutation process and documents to hand out.
