Buying your first home is a dream come true, especially when you invest in a premium property from a trusted developer like the Ganguly Group. However, the journey doesn’t end with the registration of the sale deed. To truly secure your ownership in the eyes of the government, you must complete the Mutation of your flat.
In Kolkata, mutation is the process of updating the municipal records to reflect the change in ownership. This ensures that the property tax is generated in your name and that you have a clear, marketable title for the future.
This guide provides an elaborate, step-by-step breakdown of how to navigate the mutation process under the Kolkata Municipal Corporation (KMC) and why buying from the Ganguly Group makes this legal transition significantly easier.

1. What is Mutation and Why is it Essential?

Mutation, often referred to as ‘Dakhil Kharij’, is the recording of a transfer of title of a property in the local municipal body’s records. While the Registered Deed proves you bought the property, the Mutation Certificate proves you are the recorded owner responsible for the property.
Why Mutation is Mandatory:
  • Property Tax Records: Without mutation, property tax bills will continue to be issued in the name of the previous owner or the developer.
  • Utility Transfers: You need the mutation certificate to apply for a permanent water connection or to change the name on your electricity meter.
  • Resale and Loans: You cannot legally sell your flat or take a mortgage (Home Loan) against it in the future without an updated mutation record.
  • Government Records: It acts as a secondary layer of legal protection against any fraudulent claims on your property.

2. Documents Required for Mutation in Kolkata

Before you begin the process, ensure you have the following documents ready. Buying from a transparent builder like the Ganguly Group ensures that all your paperwork is in order from day one.
  • Copy of the Registered Sale Deed: The primary proof of purchase.
  • Form A or Form B: The application form provided by the KMC Official Portal.
  • NOC from the Developer: A No-Objection Certificate from the Ganguly Group confirming the transfer.
  • Previous Tax Receipts: Proof that all municipal taxes have been cleared up to the date of possession.
  • Identity & Address Proof: Aadhaar Card, PAN Card, and Voter ID.
  • Photographs: Passport-sized photos of the owners.
  • Succession Certificate: Required only in case of inheritance (not applicable for new purchases).

3. The Step-by-Step Mutation Process (KMC)

The Kolkata Municipal Corporation has moved toward a more digital-friendly approach. Here is how you complete the process:
Step 1: Submission of Application
You can apply online via the KMC e-Mutation portal. You will need to input the Assessee Number of the parent property (provided by the Ganguly Group) and upload the scanned copies of your documents.
Step 2: Verification by the Assessor
Once the application is submitted, the Assessment-Collection department of the KMC verifies the details. An official may visit the site (your flat) to verify the area, floor number, and usage (Residential).
Step 3: The Mutation Hearing
For many new residential complexes, such as 4 Sight Grand Castle or 4 Sight Florence, a formal hearing is scheduled. You will receive a notice with a date and time. You must present the original documents to the Assessor-Collector at the designated KMC ward office.
Step 4: Payment of Mutation Fees
Upon successful verification at the hearing, the KMC will generate a ‘Mutation Fee’ demand. You can pay this fee online or at any KMC Treasury Counter.
Step 5: Generation of Certificate
Once the payment is processed, the KMC updates its records. You can then download or collect your Mutation Certificate, which will now show you as the recorded owner.

4. Why Buying from Ganguly Group Simplifies Mutation

Mutation can often become a nightmare if the developer has legal encumbrances or unpaid taxes. Here is why the Ganguly Group is the safest choice for a hassle-free experience:
  1. Zero Tax Arrears: Ganguly Group ensures that the “Mother Property” (the land on which the building stands) has its taxes paid in full up to the point of handover. This prevents your application from being rejected due to “Outstanding Dues.”
  2. Accurate Area Calculation: KMC is very strict about the difference between the area mentioned in the deed and the actual physical area. Ganguly Group’s projects like 4 Sight Superia are built strictly according to sanctioned plans, ensuring no discrepancies during the KMC inspection.
  3. Dedicated CRM Support: Their customer service team assists first-time buyers with the specific paperwork (like the Apportionment Certificate) required by the KMC to separate your individual flat’s tax from the rest of the building.
  4. Reputation and Trust: Because the Ganguly Group is a recognized name in the Kolkata Real Estate Market, their project documents are well-known to the municipal authorities, often speeding up the verification process.

5. Common Pitfalls to Avoid

  • Delaying the Process: Many owners wait years to mutate. It is best to do it within 6 months of possession to avoid penalties and complications.
  • Incomplete Paperwork: Ensure your name on the Deed exactly matches your Aadhaar/PAN.
  • Ignoring the Assessment: After mutation, check if your “Annual Valuation” is correct, as this determines your quarterly property tax.

Conclusion: Completing Your Home Ownership Journey

The mutation of your flat in Kolkata is the final leg of your journey to becoming a homeowner. While it involves a bit of bureaucracy, the long-term benefits of having a clear title and personal tax records are invaluable.
By choosing a property from the Ganguly Group, you are choosing a partner that values legal clarity as much as architectural beauty. Their commitment to providing “Clean Titles” ensures that your first home isn’t just a place to live, but a perfectly secured asset.
