Selling a flat in Mumbai is rarely held up by price. Far more often, a deal stalls because a document is missing, a society NOC takes weeks, or an old loan has not been formally closed. Serious buyers, and their banks, will ask for the full paper trail before they pay. Getting these documents ready before you list your home makes the sale faster, avoids last-minute renegotiation and signals to buyers that the property is clean. If you are planning a sale, our team can also give you an honest valuation before you list.
Here is the checklist we work through with every seller before a property goes on the market.
1. Ownership Documents
Your sale agreement and the full chain of past agreements
Keep your own registered agreement for sale, plus every earlier agreement going back to the first owner. Buyers’ lawyers and home-loan banks check this chain to confirm each transfer was valid. If an earlier agreement is lost, deal with it before listing, as it usually needs a police complaint, a public notice and an indemnity.
Index II
Index II is the extract from the Sub-Registrar’s office that records the registration of your purchase. It is one of the first documents a buyer’s bank asks for. You can usually download it from the IGR Maharashtra website using your registration details.
Stamp duty and registration receipts
Proof that stamp duty and registration were paid in full when you bought the flat.
2. Society Documents
Share certificate
In a cooperative housing society, the original share certificate in your name is proof of your membership and of the flat’s allotment. It is transferred to the buyer after the sale, so make sure you have the original.
No Objection Certificate (NOC) from the society
Most buyers and all lenders will want an NOC from the society confirming it has no objection to the sale and that there are no pending dues. Apply early, because some societies only meet once a month.
Maintenance receipts and a no-dues letter
Clear all maintenance, sinking fund and other society charges up to the date of sale and keep the latest receipts.
3. Building Approvals
- Occupation Certificate (OC): confirms the building is approved for occupation (see why it matters in our luxury apartment buyer’s checklist). Without a full OC, many buyers cannot get a home loan, which shrinks your pool of buyers.
- Commencement Certificate (CC): shows construction was approved.
- Conveyance deed (if the society has one): shows the land and building have been transferred to the society.
If your building does not have a full OC, tell your broker up front. It does not make a sale impossible, but it changes who can buy and at what price.
4. Tax and Utility Records
- Latest property tax receipts from the BMC
- Latest electricity bill, and gas and water bills where applicable
- Your PAN, which is needed for the sale deed and for the buyer’s TDS deduction
5. If Your Flat Has a Home Loan
If there is still a loan on the flat, your bank holds the original documents. You will need a loan statement showing the outstanding amount. In most sales, part of the buyer’s payment goes directly to your bank to close the loan, after which the bank issues a closure letter and returns your originals. Speak to your bank before you agree a timeline with the buyer, because releasing original documents can take a few weeks.
6. Identity and Personal Documents
- PAN and Aadhaar of every owner named on the agreement
- Passport-size photographs for registration
- If an owner is an NRI or cannot be present, a properly executed and registered power of attorney
- If the flat was inherited, the will or succession documents and the society’s transfer records
Taxes to Plan For When You Sell
If the sale value is ₹50 lakh or more, the buyer must deduct 1% TDS from the payment and deposit it with the tax department in your name. You will see this credit against your PAN. Different rules apply if the seller is an NRI, and the buyer must deduct a much higher rate.
You may also owe capital gains tax on the profit. How it is calculated depends on how long you have held the flat and when you bought it, and the rules were changed in 2024. Speak to your chartered accountant before you sign, so you know your tax in advance and can plan any reinvestment that may reduce it.

Frequently Asked Questions
How long does it take to sell a flat in Mumbai once a buyer is found?
With all documents ready and a buyer who has loan approval, registration can often happen within a few weeks. Missing documents, slow society NOCs and loan closures are the most common causes of delay.
Do I need a society NOC to sell my flat?
In most cases, yes. Buyers’ lawyers and lenders almost always ask for one, and the society needs to transfer the share certificate to the buyer after the sale.
Who pays stamp duty when a flat is sold in Mumbai?
Stamp duty and registration charges are normally paid by the buyer, unless both parties agree otherwise.
