Property Registration in Mumbai 2026: Steps, Fees and Documents

Property registration in Mumbai is busier than it has been in over a decade. Knight Frank’s reading of state registration data shows the city recorded 12,622 property registrations in September 2026, up 5% from 12,070 a year earlier and the highest September count in more than 14 years. During the Ganesh Chaturthi window alone, 5,379 documents were registered. With Diwali bookings now coming through, sub-registrar offices across the city are crowded again.

Registration is the step that makes your purchase legally yours. Without it, your bank won’t disburse the loan and you can’t prove title. Yet many buyers learn the rules only when a document is rejected at the counter.

We at Godrej Properties MMR walk buyers through registration every week. This guide covers when registration happens for new and resale flats, the exact steps at the sub-registrar, the documents and witnesses you need, what it costs in 2026, how the new e-registration and Model SRO options work, and the mistakes that cause delays. For the deeper stamp duty and ready reckoner maths, we link to our separate cost guide rather than repeat it here.

Under the Registration Act, 1908, any document that transfers ownership of immovable property worth more than Rs 100 must be registered. In Maharashtra, an agreement for sale of a flat is also registered, because the Maharashtra Stamp Act charges full stamp duty on it. The timing depends on what you are buying.

Two points trip buyers up. First, for a new flat, you don’t register again at possession. The agreement registered at booking is your main ownership document until the society is formed and the building is conveyed to it. Second, the clock matters. A document must be presented for registration within four months of the date it is signed. A late document can still be accepted within a further four months on payment of a fine, but after eight months it can’t be registered at all, so sign and register in the same week where you can.

Once registered, the document is scanned and returned to you, and an Index II extract is generated. Index II is the public record of the transaction, showing the parties, property, consideration and stamp duty paid. Lenders, the society and future buyers will all ask for it.

The process is the same at your local sub-registrar office (SRO), a Model SRO or a developer’s e-registration desk. Here is the sequence for a typical Mumbai purchase. For where registration sits in the wider buying process, see our first-time home buyer’s guide to RERA, home loans and registration in Maharashtra.

1. Agree the draft. Get the agreement for sale or sale deed drafted and checked by a lawyer. For new projects, compare it with the MahaRERA model agreement the developer uploaded, and check that the carpet area and RERA number match.
2. Calculate stamp duty. Duty is charged on the agreement value or the ready reckoner value, whichever is higher. The IGR Maharashtra portal (igrmaharashtra.gov.in) has an online calculator.
3. Pay through GRAS. Pay stamp duty and the registration fee online through the Government Receipt Accounting System (GRAS). You can also use e-SBTR through an authorised bank, or franking. Save the challan, because you will need its number on the day.
4. Enter the data (PDE). Fill in the property and party details through Public Data Entry on the IGR portal. This generates a token that the SRO uses to pull up your document.
5. Book an appointment. Book a time slot online for your chosen SRO. Under the One State One Registration scheme announced in 2025, a pilot covering 32 sub-registrar offices in Mumbai city and suburbs lets you register at any of them rather than only the one covering the property’s area [VERIFY: confirm current status with your SRO].
6. Attend with witnesses. The buyer, the seller (or the developer’s authorised signatory) and two witnesses appear in person with original ID. The SRO takes photos and thumb impressions, and Aadhaar-based biometric verification is done for the parties.
7. Admission and scanning. The sub-registrar checks the stamp duty, admits the document and scans it. The original is usually returned the same day.
8. Collect Index II. Download or collect the Index II and keep a certified copy with your property file.

Most rejections at the counter come from a missing original or a name that doesn’t match across documents. Carry originals plus two self-attested photocopies of everything. For a standard Mumbai flat purchase, this is the list.

• Identity and PAN: PAN card and Aadhaar for every buyer and seller. A buyer without PAN must file Form 60. NRIs and OCIs bring their passport.
• The document itself: the final agreement for sale or sale deed, printed and signed on every page as the SRO requires.
• Payment proof: the GRAS challan or e-SBTR receipt for stamp duty and the registration fee.
• Property papers: for new flats, the RERA registration and approvals the developer attaches. For resale, the previous registered agreement, share certificate and society NOC.
• Authority letters: a board resolution or power of attorney if a company or an attorney signs for a party.
• Two witnesses: adults with original photo ID and Aadhaar. They don’t need to know the property, only to confirm the parties signed.

If the property is above Rs 50 lakh, also deduct 1% TDS under Section 194-IA of the Income Tax Act before paying the seller, and keep the Form 26QB challan in the same file. It isn’t checked at the SRO, but your bank and the seller will both ask for it.

The money side of property registration in Mumbai is simpler than it looks. Ready reckoner rates for 2026-27 were held at 2025-26 levels from 1 April 2026, so the floor value for duty hasn’t moved this year. The rates below are what most Mumbai buyers pay.

The 1% metro cess has applied in Mumbai since 2022 and is already built into the 6% figure, so don’t add it a second time. Thane and Pune add a further 1% local body tax, which takes them to 7%. Because the registration fee is capped at Rs 30,000, almost every Mumbai flat pays the full cap, since any property above Rs 30 lakh hits it.

Under-stamping is now costly. Maharashtra has introduced a penalty of up to Rs 1 lakh for insufficient stamp duty, on top of recovering the shortfall. For a full worked breakdown with GST, loan costs and examples for Thane and Panvel, see our guide to ready reckoner rates 2026-27 and stamp duty in Mumbai.

Stamp duty collected on Mumbai registrations fell 5% to Rs 1,227 crore in September 2026 even as the number of registrations rose, which Knight Frank linked to a shift in the mix of transactions. More deals, at a lower average ticket, are going through the city’s sub-registrar offices.

If you are buying a new flat, there is a good chance you will never queue at an SRO. IGR Maharashtra’s e-Registration 2.0 system, on the iSarita portal, lets registered developers complete first-sale agreements online. The buyer does Aadhaar-based e-KYC and biometric verification, the developer’s side is already authenticated, and the document is registered without a counter visit. The current rollout began in September 2025 at a Panvel project, and reports say about 300 developers across the state have signed up. It applies only to first sales, so resale flats still go through a regular SRO.

E-registration saves time, but the document you approve online is the same legal agreement, so read it as carefully. These are the mistakes we see most often:

• Names that don’t match. A buyer’s name spelt one way on PAN and another on Aadhaar stalls biometric checks. Fix it before booking a slot.
• Deciding co-owners too late. Adding a spouse after registration means a fresh document and fresh duty. A woman buying alone saves 1%, but a joint purchase with a man pays the full rate.
• Paying duty on the wrong value. If the ready reckoner value is higher than your price, duty is due on the higher figure, and the gap can also be taxed as income under Section 56(2)(x).
• Missing the four-month window. Signing early and registering later invites fines, and after eight months the document can’t be registered.
• Not checking Index II. Typing errors in the area, flat number or consideration are common. Check Index II the same week and ask for a correction while the file is fresh.

On timelines, a complete file at a regular SRO usually takes one to two hours on the day, with the original returned the same day [VERIFY: varies by office and season]. Plan for longer in October and March, which are the busiest months. March 2026 recorded 15,983 registrations in Mumbai, the highest month of the year so far.

For new homes from Godrej Properties Limited, the developer’s documentation team usually handles registration at booking. That makes your own check of the draft and Index II more important, not less.

Ready projects bring registration and possession closer together. At Godrej Nest in Kandivali East, a completed project with homes from about Rs 1.21 crore, a buyer typically registers the agreement and takes possession within weeks, and pays no GST because the OC is in place. At Godrej Urban Park in Chandivali, which had a MahaRERA proposed possession date of September 2026, most agreements were registered years ago, and buyers now need their registered agreement and Index II at hand for loan disbursement and possession.

Q: How much is the registration fee in Mumbai in 2026?

The registration fee is 1% of the property value, capped at Rs 30,000. Because any property above Rs 30 lakh hits the cap, almost every Mumbai flat pays the full Rs 30,000. It is paid online through GRAS along with stamp duty, before your appointment at the sub-registrar office.

Q: Can property registration in Mumbai be done fully online?

For first sales by registered developers, yes. IGR Maharashtra’s e-Registration 2.0 lets you complete e-KYC and biometrics online without visiting an SRO. Resale flats still need the buyer, seller and two witnesses to appear in person at a sub-registrar office, though payment, data entry and appointment booking are all online.

Q: Do I need to register again when I take possession of a new flat?

No. For a new flat, the agreement for sale registered at booking carries the full stamp duty and is your ownership document. Possession is a separate handover by the developer. The building is later conveyed to the housing society through its own registered deed.

Q: How many witnesses are needed for property registration?

Two. Each must be an adult who appears in person with original photo ID and Aadhaar. Their photos and thumb impressions are taken at the SRO. They don’t need any connection to the property, only to confirm that the parties signed in their presence.

Q: What happens if I register the agreement late?

A document must be presented within four months of signing. Within the next four months it can still be registered on payment of a fine. After eight months from signing, the sub-registrar can’t register it, and you will need to execute a fresh document.

Property registration in Mumbai is quicker in 2026 than it has ever been, with online payment, e-registration for first sales and the new Model SRO at BKC. The rules haven’t softened, though. Pay duty on the right value, register within four months, bring two witnesses with original ID, and check your Index II before you file it away. Get those right and the visit is short.
