Deemed Conveyance occurs when the builder/land owner or the legal heir refuse to co-operate in handing over conveyance to the Co-operative Society under the Section 11(3) of Maharashtra Ownership Flats Act, 1963. In such case, the housing society has to appear before the District Deputy Registrar, who will hear the case of both parties i.e. the housing society and the builder and would pass the required order of Conveyance. It is a remedial measure obtained by the society against the builder/landowner who does not wish to convey the property since he/she sees a commercial gain out of the property in future. This could include usage of potential FSI for their personal gain.
Deemed Conveyance is final conveyance and the same can be registered. Once the designated Competent Authority has passed the order, there cannot be an appeal against it.

NEED FOR DEEMED CONVEYANCE:
In a situation when a promoter or owner of residential premises/ buildings does not transfer/convey the ownership of the flats to the housing society or association of persons (AOP), the society or AOP can make an application to Registrar of Co-operative Housing Societies, to transfer the ownership of the said flats to them. This process is carried on through Deemed Conveyance of the title of the buildings and land in favour of the Society or AOP without the need of the builder to do so.

DISADVANTAGES OF NOT HAVING CONVEYANCE DEED:
Even though you have purchased ownership flat, you are not the owner of the land and building. In the event of a building collapse or damage to the building, you cannot reconstruct the building without the permission of the Builder / Land owner.
1. The Builder/Developer may mortgage the property purchased by you as he is the legal owner and holding the Title Deeds of the Property.
2. The Builder/Developer may tap the benefits in case the building is later taken up for redevelopment or if the plot has some unutilized floor space index.
3. The Builder may make profit by sale of open spaces, gardens, terrace, parking space belonging to the Society.
4. The Builder may demand a huge amount from the Society, if Conveyance is sought by the Society after a lapse of many years.
5. The Builder may sell the entire Development Rights and the Legal Rights on the land to third party and create a third party interest in the Property and the Society will have to incur a huge amount to clear the same.
