Does a possession letter replace the occupancy certificate?

By Gaurav Mongia, acre&key · Published 18 Oct 2026 · Updated 18 Oct 2026

Direct answer: No. A possession letter is the builder's own letter offering you the flat. The occupancy certificate (OC) is issued by the competent authority and permits people to occupy the building. Under the RERA Act, the builder must obtain the OC and make it available to you, and your two months to take possession run from the OC.

Buyers often hear "possession letter is ready" and treat it as the finish line. It isn't. One document comes from the builder. The other comes from the authority that approved the building. They answer different questions, and the law ties your duties to the authority's document, not the builder's.

What is each document, and who issues it?

The RERA Act defines the occupancy certificate in Section 2(zf). It is "the occupancy certificate, or such other certificate, by whatever name called, issued by the competent authority permitting occupation of any building, as provided under local laws, which has provision for civic infrastructure such as water, sanitation and electricity".

The Act doesn't define a "possession letter" at all. In practice it is the written offer of possession that the builder sends you. The K-RERA proforma agreement describes that step in clause 7.2: the promoter, "upon obtaining the occupancy certificate", shall "offer in writing the possession" of the flat.

The completion certificate is a third document. Section 2(q) defines it as the certificate that the project "has been developed according to the sanctioned plan, layout plan and specifications". The central RERA FAQs put it simply: the OC is about occupation of the building and whether it is habitable, while the completion certificate is about the whole project matching the sanctioned plan. Our page on OC and CC covers both in more depth.

Why does it matter which comes first?

Because the Act and the model agreement both put the OC first.

• Section 11(4)(b): the promoter is "responsible to obtain the completion certificate or the occupancy certificate, or both, as applicable" and "to make it available to the allottees individually or to the association of allottees".
• Section 19(10): every allottee "shall take physical possession" of the apartment "within a period of two months of the occupancy certificate issued for the said apartment".
• Proforma clause 7.2: the offer of possession comes after the OC, "to be taken within two months from the date of issue of occupancy certificate".

So your two-month clock to take possession starts from the OC date, not from the date printed on the possession letter. If you get a letter without an OC behind it, you don't yet know when that clock started, or whether it has.

What should I do if the builder offers possession without an OC?

Ask for a copy of the OC for your building before you accept the keys or sign the handover papers. Section 11(4)(b) already obliges the builder to make it available, so the request is ordinary.

If there is no OC, take stock before you move anything in:

1. Check your agreement's possession clause and date. Under the proforma clause 7.1, timely possession "along with ready and complete common areas with all specifications, amenities and facilities" is "the essence of the Agreement".
2. Look at the project page on the Karnataka RERA portal. Here's how to check a project on the Karnataka RERA website.
3. Speak to your lawyer about where you stand. Section 18(1) covers a promoter who "fails to complete or is unable to give possession" in line with the agreement or "duly completed by the date specified therein".
4. If you're aggrieved, Section 31 lets you complain to the Authority. See how to file a complaint with Karnataka RERA online.

Don't treat this as a reason to stop paying what's due under your agreement without advice. Section 19(6) makes you responsible for payments "in the manner and within the time as specified in the said agreement for sale", and Section 19(7) adds interest for delay.

Does a possession letter make me the owner?

No, and neither does the OC. Ownership moves through a registered conveyance deed. Section 17(1) says the promoter "shall execute a registered conveyance deed in favour of the allottee" and hand over physical possession. Where there's no local law on timing, the conveyance deed has to be carried out "within three months from date of issue of occupancy certificate". The proforma repeats that three-month line in clause 7.2.

So the usual order under the Act and proforma is: OC, then offer of possession, then physical possession and the registered sale deed. Our page on allotment letter vs agreement for sale vs sale deed explains where each paper sits, and Kaveri 2.0 registration steps covers the registration itself.

For the standard form of the agreement for sale itself, see the Karnataka RERA model agreement.

Who pays maintenance and outgoings around possession?

The Act draws the line at physical possession. Section 11(4)(g) says the promoter shall "pay all outgoings until he transfers the physical possession" to the allottee or the association. The list includes municipal or other local taxes, water and electricity charges and maintenance charges that the promoter has collected from allottees for that purpose.

The proforma then deals with buyers who delay. Clause 7.3 says that if you fail to take possession within the time in clause 7.2, you "shall continue to be liable to pay maintenance charges". That's another reason to know the OC date: the two months in clause 7.2 run from it.

What else starts when I take possession?

Two things in the Act run from possession.

• Defect liability. Under Section 14(3), structural defects or defects in workmanship, quality or services brought to the promoter's notice "within a period of five years by the allottee from the date of handing over possession" must be fixed "without further charge, within thirty days". Keep the date you actually took possession. More in defects after possession under RERA.
• Association handover. Section 17(2) says that after obtaining the OC and handing over physical possession, the promoter must hand over the necessary documents and plans, including common areas, to the association of allottees or the competent authority. See apartment association handover in Karnataka.

Carpet area is also settled around the OC. Proforma clause 1.7 has the promoter confirm the final carpet area once the OC is granted. If it has shrunk, the excess is refunded within sixty days with interest. If it has grown by up to three percent, the promoter may ask for the extra at the agreed rate.

Cover for the flat itself is a separate question, covered in home insurance for a new flat.

What should I check before I accept possession?

1. A copy of the OC for your building, and its date.
2. The possession letter's date, flat number and the carpet area it states, matched against the final carpet area confirmed after the OC.
3. Whether the letter asks you to sign indemnities or undertakings, and what they say. Clause 7.3 refers to "necessary indemnities, undertakings and such other documentation as prescribed in this Agreement", so compare them with your agreement.
4. The date from which maintenance is charged.
5. A walk-through of the flat itself. Use our flat possession inspection checklist.
6. The timeline for the registered sale deed.

Frequently asked questions

Is a possession letter the same as an occupancy certificate?

No. The possession letter comes from the builder. The OC is issued by the competent authority under local law and permits occupation of the building, as defined in Section 2(zf) of the RERA Act.

Who has to get the OC, the builder or the buyer?

The builder. Section 11(4)(b) makes the promoter responsible for obtaining the completion certificate or occupancy certificate, or both, and making it available to allottees or their association.

When does my two-month possession window start?

From the occupancy certificate. Section 19(10) says allottees take physical possession within two months of the OC issued for their apartment, and K-RERA proforma clause 7.2 says the same.

Does a possession letter transfer ownership of the flat?

No. Ownership passes through a registered conveyance deed under Section 17(1). Where no local law fixes the timing, that deed is due within three months of the OC.

When does the five-year defect period start?

From the date possession is handed over. Section 14(3) covers defects brought to the promoter's notice within five years of that date, which the promoter must fix free within thirty days.
