A 22 year old cooperative housing society in the Mumbai suburbs decided in 2024 that its ageing building needed redevelopment. The flats were owned, the maintenance was paid, the society was registered. Then their lawyer asked a simple question: does the society own the land? It did not. The builder had never executed the conveyance, and two decades on he was untraceable and the land still stood in his name. Every owner in that building held a flat but not a share of the ground beneath it, and their redevelopment plan stalled before it began. Conveyance is the quiet document that decides whether a society controls its own future.

The short answer. Buying a flat gives you your apartment, but the land under the building is meant to be owned collectively by your society through a document called conveyance. Under Section 11 of the Maharashtra Ownership Flats Act, the builder must convey the land and building to the society within four months of the society's registration. If the builder fails, owners can seek a deemed conveyance from the District Deputy Registrar. The trade off buyers overlook: a flat without conveyance of the land can still be lived in, but it cannot easily be redeveloped, and the builder retains a grip on its future.

What is conveyance, and why does it matter to a flat buyer?

Conveyance is the legal transfer of ownership of the land and building from the builder to the cooperative housing society formed by the flat buyers. When you buy a flat, you get ownership of your apartment, but the plot the building sits on is supposed to pass to the society as a whole. Conveyance is the deed that makes that happen and puts the land legally in the society's name.

It matters because without it the society does not truly own its ground. A conveyed society can raise loans against its property, undertake reconstruction and redevelopment, hold a clean marketable title, and protect itself from a builder quietly mortgaging or selling the land from under it. Without conveyance, flat owners cannot reconstruct without the builder's permission, and the builder keeps control over redevelopment rights and the profits that come with them. For a buyer, conveyance is the difference between owning a home and owning a home on land someone else still controls.

What does MOFA require the builder to do?

The Maharashtra Ownership Flats Act places a clear duty on the promoter. Under Section 11, the builder must execute a conveyance transferring the title of the land and building to the society within four months from the date the cooperative housing society is registered. The promoter is also required to file a copy of the executed conveyance with the Competent Authority. This is not optional courtesy; it is a statutory obligation.

The law goes further to protect buyers. Once a developer has sold all the flats and a society of flat purchasers is formed, the developer is divested of title in the land and building, which the law requires to be transferred to the organisation of flat purchasers. In other words, the land is meant to be the owners', and the builder is meant to sign it over. The problem in practice is that many builders simply do not, and that is where the next remedy comes in.

What is deemed conveyance, and who grants it?

Deemed conveyance is the legal remedy that lets a society obtain ownership of the land even when the builder refuses or fails to cooperate. When a builder does not execute the conveyance, the society can present its case to the District Deputy Registrar, who, after hearing both sides, can order a unilateral conveyance that is then registered as a deemed conveyance. It is the law's way of ensuring a builder's inaction does not permanently trap the owners.

According to a guide to conveyance and deemed conveyance, the process protects flat owners from problematic developers by transferring the title to the society through the Competent Authority. For a buyer, the takeaway is reassuring but conditional: the route exists, but it takes effort, documentation and time. It is far easier to buy into a society that already holds conveyance than to chase a deemed conveyance years later.

What can go wrong if a society never gets conveyance?

If a society never obtains conveyance, its problems tend to surface at the worst moment, usually when it wants to redevelop an ageing building. Without the land in its name, the society cannot freely reconstruct, cannot easily mortgage the property to fund works, and does not hold a fully marketable title. The redevelopment that could unlock value and safety for every owner is blocked on a technicality that should have been closed within months of the society forming.

There is a second, quieter risk. As long as the land stands in the builder's name, the builder retains a legal foothold over it, and in troubled cases that has meant land being mortgaged or entangled in the builder's own disputes. Flat owners can then find their collective asset caught up in a fight they were never part of. None of this makes your individual flat vanish, but it can freeze the society's ability to act and erode the value of what everyone owns.

The frustration for owners is that the fix was always meant to be simple and prompt. The four month window in the law exists precisely so that conveyance happens while the builder is still around and cooperative, long before redevelopment becomes urgent. When that window is missed, a routine transfer turns into a project, and a project that owners must chase. That is why experienced buyers treat a completed conveyance as a genuine mark of a well run society, and a long pending one as a question that deserves a real answer.

Conveyance versus deemed conveyance: how do they compare?

Both put the land in the society's name, but they get there very differently. This table shows what separates the smooth path from the fallback.

The lesson for a buyer is straightforward. A society that already holds conveyance has closed a major risk. A society still relying on the possibility of deemed conveyance has work ahead, and you should factor that into your decision and your questions.

What should a Mumbai buyer check about conveyance before buying?

Whether you are buying a new flat or a resale in an older building, ask about conveyance early. These checks tell you where the society stands.

1. Ask whether the society has obtained conveyance of the land and building in its own name.
2. For a new project, confirm the builder's commitment to execute conveyance after the society is formed.
3. In a resale, ask the society office directly, not just the seller, about the conveyance status.
4. If conveyance is pending, ask whether a deemed conveyance application has been filed or is planned.
5. Check that the society is properly registered, since the four month conveyance clock runs from that date.
6. Review the title and land documents with a lawyer to confirm the land position is clean.
7. Weigh a pending conveyance into your price and timeline, especially if redevelopment is likely.

Conveyance sits alongside the other completion checks a Mumbai buyer should make. Confirm the building has its occupancy certificate before you move in, and for a new project, verify the developer on MahaRERA before you book.

Does buying a flat give you ownership of the land under it?

Buying a flat gives you ownership of that apartment, but not individual ownership of the land beneath the building. The land is meant to be owned collectively by the society, and that collective ownership is completed only through conveyance. Until the society holds the conveyance, the land title has not fully passed to the owners as a body, even though each of them owns a flat.

This is why conveyance deserves a place on every buyer's checklist, not just the society committee's agenda. It does not change your right to live in and use your flat day to day, but it shapes what your society can do with its most valuable shared asset. A buyer who asks about conveyance before purchase understands the property fully, and is far less likely to be surprised by a stalled redevelopment a decade later.

Frequently asked questions

What is conveyance in a Mumbai housing society?

Conveyance is the legal transfer of ownership of the land and building from the builder to the cooperative housing society formed by flat buyers. It puts the land in the society's name, which is what allows the society to redevelop, raise loans and hold a clean marketable title. Individual flat ownership does not by itself achieve this.

How long does a builder have to give conveyance?

Under Section 11 of the Maharashtra Ownership Flats Act, the builder must execute conveyance of the land and building to the society within four months from the date the society is registered. The promoter must also file a copy with the Competent Authority. Many builders delay or fail to do this, which is why the deemed conveyance remedy exists.

What is deemed conveyance and who grants it?

Deemed conveyance is a remedy for when a builder does not execute conveyance. The society applies to the District Deputy Registrar, who, after hearing both sides, can order a unilateral conveyance that is registered as deemed conveyance. It transfers the land to the society despite the builder's inaction, though it takes documentation, hearings and time.

Should I worry if a society has not got conveyance yet?

It is worth taking seriously, especially for an older building likely to need redevelopment. Without conveyance the society cannot freely reconstruct or mortgage the property, and the builder retains a foothold over the land. Ask whether a deemed conveyance is being pursued, and factor any pending conveyance into your price and timeline.
