Buying a Flat in Bangalore: Five Documents and Which One Makes You the Owner
A flat purchase in Bangalore leaves the buyer with a folder of papers whose names sound alike. Mixing them up is common, and it can leave a family living in a home it does not legally own. This article takes each paper in turn, says who signs it, states what it proves and names the one that completes the transfer.
Ownership Starts at Registration
Property law demands a registered instrument for any sale of immovable property valued at Rs. 100 or higher, so the sale deed alone moves title. Duty is paid on it at the full rate. Builder and landowner both sign it before the registering officer.
The deed conveys the apartment along with the share of land that goes with it. Under RERA's Section 17 the developer is bound to sign it within a quarter of the OC, unless local law has another period. If the deed is unregistered, the public register never lists the buyer as owner.
Later steps depend on it as well. Khata transfer follows from the deed, and the lender keeps it as security. The upfront cash in this site's EMI calculator already allows for the stamp duty and registration paid at this stage.
The Usual Timeline
Most RERA-registered projects produce papers in this order, though the dates vary.
- Allotment letter, soon after the first payment
- Agreement for sale, registered before the large instalments begin
- Occupancy certificate, once the construction ends and the authority inspects
- Possession letter, when keys are handed over
- Sale deed, in the buyer's name
Steps three to five can fall within a few weeks, which explains the mix-ups. Knowing each paper's limits lets a buyer refuse to treat one as another.
The Allotment Letter: a Reservation
The sheet names the unit, its floor and block, together with the agreed price and instalment plan. Lenders want a copy as soon as the loan application starts. It is therefore usually the first page in the bank's file.
Legally it is thin. It gives the buyer no stake in the plot or the construction, and the developer can cancel under its terms if the buyer defaults on payments. Its one strength is fixing flat and price on paper early.
The Agreement for Sale: a Binding Promise
This contract governs everything until the deed. RERA's Section 13 stops any builder from collecting above 10% of the price upfront until the agreement is registered. It sets out carpet area, specifications, the instalment stages and the promised handover date.
A registered agreement lets a buyer ask a court to enforce the sale on the agreed terms. Even so, it only promises a transfer later. Until the deed, the land and flat belong to the builder and the landowner.
The Occupancy Certificate: the Authority's Word
Unlike the others, the OC is issued by a government body. The authority that cleared the plan sends inspectors to the completed building and then certifies it. Within the city limits it is the Greater Bengaluru Authority's city corporation; further out, the BDA or a local planning authority.
It confirms that construction matches the plan and that residents may move in. RERA's Section 11 makes the promoter responsible for getting it and passing it on to buyers. Going without it causes real problems.
- Section 19 gives allottees two months from the OC to take possession.
- Blocks of flats normally need it before permanent utilities are connected.
- The final slice of a home loan is often released only against it.
- A later buyer's lawyer will ask for it.
In large layouts an OC may be partial, covering completed towers only. Whatever certificate the buyer holds must name the tower and floors containing the flat, because a neighbouring tower's OC says nothing about this one.
The Possession Letter: Keys Changed Hands
A handover letter, as it is sometimes called, is the builder's confirmation that the flat was delivered on a given day. The date starts two clocks: the five years for structural defect claims under RERA's Section 14, and usually the monthly maintenance bill.
Its weakness is that the builder alone writes it. It cannot show that the authority approved the building, and it only tells who holds the keys, a different question from who owns the home.
Is a possession certificate any different?
The names get used loosely. A possession certificate more often comes from a public body, such as the BDA handing an allotted site to its allottee. It also proves delivery only, and title still waits on the registered deed.
Quick Reference
This list matches each paper to its author and what it settles.
- Allotment letter: from the builder, shows a flat is held at a price, ownership unchanged
- Agreement for sale: signed by both parties and registered, shows the terms of the coming sale, ownership unchanged
- OC: from the sanctioning authority, shows the building matches the plan and is habitable, ownership unchanged
- Possession letter: from the builder, shows the date of handover, ownership unchanged
- Sale deed: registered before the sub-registrar, shows the flat and its land share have been conveyed, ownership with the buyer
How Buyers Get Caught
Imagine a buyer who has paid the full price and moved in on the strength of a possession letter, after being told the OC would follow. Leverage has gone, because no payment is left to withhold. Years later the deed is still unregistered, the flat is in the builder's name, and no sale or mortgage can go ahead.
A second trap is a resale purchase from someone holding just an allotment letter or an agreement. That seller has a contractual right, not title, so the builder must consent and new documents are needed. Anyone offered such a flat should ask for the deed before paying.
Handover Day Routine
Begin with the OC, matching its tower and floors to the flat. Inspect the flat, accept the possession letter and register the deed immediately or within the agreed period. Where possible, keep the last instalment back until both the OC and the deed are in hand.
Buyers weighing ready homes in Bangalore may write to us to learn how far a given project has progressed on these papers. All five documents and the payment receipts belong in one file for as long as the flat is owned.
