Mutation is the update of the record-of-rights to show a new owner after a transfer, an inheritance or a partition. In West Bengal it is administered by the Block Land and Land Reforms Officer (BL&LRO) and, above that, the District Land and Land Reforms Officer. You can check the status of a mutation application through the state's online land-record services using the application or case number, and also by asking at the BL&LRO office that received the application.
What mutation is and what it is not
Mutation changes the revenue record for the collection of land revenue and for assessment. It is an administrative act of the revenue authority. It does not by itself create, transfer or extinguish title to the land, and a mutation order is not a substitute for a properly registered deed or for a decree of a civil court. A person whose name appears in the record-of-rights is presumed to be in possession for revenue purposes, but a rival claiming title has to establish it in a civil suit, not merely by mutation.
Who applies, and where
The application is made by the person whose name is to be recorded — typically the transferee under a registered deed, an heir, or a co-sharer after partition. It is filed before the BL&LRO of the block in which the land falls, and not before the office covering the applicant's own residence. Where the land falls in more than one block, an application is needed before each. In a city, the corresponding revenue office handles it under the same procedure.
Documents usually required with the application
- A written application or petition giving the plot details, the mouza and the ground of mutation.
- A certified copy of the registered deed — sale, gift, partition or settlement.
- For inheritance, the death certificate of the recorded owner and the heirship or succession papers, and a probate or letter of administration where the transfer is under a will.
- A copy of the existing record-of-rights showing the name of the previous owner.
- Recent land revenue receipts showing that dues are paid.
- Identity and address proof of the applicant.
- Any earlier mutation order or order sheet on the same plot, if there has been one.
How to check the status online
- Find the receipt or acknowledgement you were given when the mutation application was filed, and note the application or case number.
- Open the state's online land-record services on the official portal.
- Choose the option for mutation or application status.
- Select the district, then the block, then the mouza in which the land falls.
- Enter the application or case number and, where asked, the plot number, and submit.
- Review the status shown — whether the case is pending, listed for hearing, or disposed of — and save a copy or screenshot of the page.
- If the case appears pending beyond the usual cycle, follow up at the BL&LRO in writing, quoting the case number and attaching the earlier acknowledgement.
- Once mutation is allowed, obtain a certified copy of the corrected record-of-rights from the office or through the portal's record-of-rights service.
How the mutation case proceeds
After the application is filed, the office causes notice to be served on the recorded owner and on other interested parties, and the case is posted for hearing. Where there is a dispute of fact, the officer may order a field verification or a spot enquiry and call for the records. If no one objects and the deed and revenue dues are in order, the record is corrected and the new record-of-rights is issued. If an objection is raised that goes to title rather than to the revenue entry, the officer may record it and direct the parties to the civil court, because a mutation authority does not decide questions of title between rival claimants.
Common mistakes that hold up a mutation
- Filing at the wrong BL&LRO — the one for the mouza where the land lies is the correct office.
- Relying on an unregistered deed, which cannot ordinarily support mutation.
- Not serving or not impleading an interested party, so that a co-sharer or a rival claimant is left out of the notice stage. A mutation obtained without notice to interested parties can be reopened.
- Treating mutation as proof of title, and later discovering that a civil suit is still needed.
- Missing revenue dues or old arrears, which the office may insist be cleared first.
- Losing the acknowledgement, which makes the online status check impossible to run.
Frequently asked questions
Is there a time limit to apply for mutation?
There is a settled practice that mutation should be applied for promptly after the deed is registered, because land revenue and assessment follow the record. Lengthy delay does not by itself bar the application, but it makes proof of possession and of the chain of title harder, and it invites objections from other claimants.
Can I check the status without the application number?
Sometimes the portal allows a search by district, block, mouza and plot. Where the case number is lost, the office record at the BL&LRO is the reliable source, and a written request quoting the plot details will usually bring out the case number.
Does mutation give me ownership?
No. Mutation affects the revenue record only. Ownership rests on a valid and registered transfer, on inheritance, or on a decree. A mutation entry can be challenged by a person claiming title, and the dispute would then be decided by a civil court.
Do I need an advocate to apply or to check the status?
Checking the status online is something most people do themselves. Help is worth taking where the deed is unregistered, where an objection has been raised, where the recorded owner has died and the heirs are disputed, or where the revenue office has referred the parties to the civil court. Charging for such work depends on the stage and the complexity; our published consultation and appearance fees are set out on our pricing page.
