Mutation is the process of updating the revenue or municipal record to show the name of the current owner of a property. In West Bengal it runs on two tracks: land mutation before the Block Land and Land Reforms Officer, the BL&LRO, under the West Bengal Land Reforms framework and the mutation rules, and municipal mutation for a property within Kolkata before the Kolkata Municipal Corporation under the KMC Act 1980. Mutation changes the name in the public record for the purpose of assessment and revenue; it does not by itself confer or create title to the property, and it does not decide ownership disputes between rival claimants.
Who this applies to
This guide is for a buyer who has just registered a deed, an heir who has inherited property on the death of the recorded owner, and a co-owner who wants the record to reflect a partition or a settlement. It applies to agricultural and non-agricultural land recorded in the land records and to premises assessed for property tax within the municipality. It is useful both for land in the districts and for a flat, house or plot in Kolkata.
What mutation does and does not do
Mutation aligns the record of rights or the assessment register with the actual owner, so that land revenue or property tax is billed to the right person and so that future dealings are not obstructed by a stale entry. It is not a title proceeding. A mutation entry is relevant and can be relied on as evidence, but a civil court decides questions of title, and a mutation order does not override a decree or a registered deed. Anyone in Calcutta or the districts who treats a mutation as proof of ownership makes a costly mistake.
The two routes
For land recorded in the revenue records, the application is made to the BL&LRO of the block concerned, and the case is registered as a mutation case. For property within Kolkata assessed to property tax, the application is made to the Kolkata Municipal Corporation, which updates the assessment record. Properties in Bidhannagar and Howrah fall within the Bidhannagar Municipal Corporation and the Howrah Municipal Corporation respectively, and their own procedure applies. For a flat in a co-operative or an apartment association, the society record is also updated separately.
What the application should contain
- Name and address of the applicant and the relationship to the recorded owner.
- Details of the property: plot or dag number, khatian, mouza and j.l. number and area for land; holding number, premises address and assessment number for municipal property.
- The ground of mutation: purchase, inheritance, gift, partition or settlement.
- The registered deed number, its date and the registration office, or the succession particulars.
- The relief sought and a list of the documents enclosed.
- A declaration that the facts are true, and the applicant's signature.
Documents to attach
- Registered sale deed, gift deed, partition deed or will, as the case may be.
- Proof that the transferor was the recorded owner, such as an earlier record of rights or a rent receipt.
- Latest land revenue or property tax receipts.
- For inherited property, the death certificate of the recorded owner and the succession certificate, probate or heirship particulars as required.
- Holding number and last paid tax receipt for municipal property.
- Identity proof and, where required, an affidavit.
- Copies of the earlier mutation order, if any, and a site or sketch plan where the records demand it.
The hearing and notice to others
Mutation cases are usually heard at the office of the BL&LRO or the municipal assessment department rather than in a courtroom. Where there is more than one claimant, or where the record is disputed, notice may be issued to the other interested persons and they are heard before the entry is changed. An applicant should attend the hearing with the original documents and a set of copies. An uncontested purchase or inheritance case usually proceeds without difficulty; a contested one may be adjourned several times.
Checking status on Banglarbhumi
The land records of West Bengal are published on the state land records portal, Banglarbhumi. You can look up the record of rights for a plot, see the recorded owner, and track the status of a mutation case where the facility is available. For a Kolkata property, the corresponding information on assessment is obtained from the Kolkata Municipal Corporation. Keep a printed copy of the record in the file, as it is the version the office will refer to.
Consequences of a wrong entry
A wrong or stale entry can lead to land revenue or tax being demanded from a person who no longer owns the property, can obstruct a future sale or loan, and can be relied on by a rival claimant. If an entry is incorrect, the remedy is to apply for correction or mutation with the documentary proof, and where the dispute is really about ownership, to seek a civil remedy rather than to expect the revenue or municipal office to decide title.
Does mutation give me ownership?
No. Mutation updates the record for revenue and assessment purposes. It is evidence of possession and payment, but title is decided by the courts on the strength of the deed and the law.
Which office handles Kolkata property?
For land in the districts, the BL&LRO of the block; for premises within Kolkata assessed to property tax, the Kolkata Municipal Corporation. Bidhannagar and Howrah properties go to their own municipal corporations.
Can mutation be refused?
Yes. If the deed is not registered, the applicant's link to the recorded owner is not shown, or the property is the subject of a dispute, the office may refuse or defer the entry until the objection is settled.
