Bombay High Court clarifies when land entitlement crystallises in multi-building layouts

A Single Bench of the Bombay High Court, in Satellite Garden I Co-operative Housing Society Limited v State of Maharashtra through the Ministry of Housing & Ors.¹ and two connected petitions, has laid down guidelines for deemed conveyance in multi-building layouts. The order, dated 16 September 2026, sets out the framework for determining the proportionate division of land among societies in such layouts.

The judgment addresses a recurring difficulty in large, phased layouts. Where buildings are constructed at different points in time, the sanctioned plan, applicable floor space index (FSI) regime, or available development potential may change over the course of development. This can make it challenging to determine the proportionate basis for conveying the underlying land to the societies representing the different buildings.

The Court has sought to resolve this uncertainty by holding that a society’s proportionate entitlement to the layout land becomes “frozen” or “crystallised” at a defined point in time. Once crystallised, this entitlement cannot subsequently be diluted merely because the developer revises the layout or deploys additional FSI or transferable development rights (TDR) for buildings constructed later.

The dispute arose from a layout development for a property in Goregaon (East), Mumbai, which was developed in phases and comprised multiple buildings. As development progressed, the configuration of the layout and the development potential available to different buildings/sub-plots changed over time. The societies representing the different buildings sought conveyance of their respective interests in the layout land. However, the Competent Authority did not apply a uniform yardstick to determine conveyance in the multi-structural layout. It adopted different approaches to determine the extent of land to be conveyed to each society, which resulted in materially different outcomes. The societies challenged the Competent Authority’s orders before the Bombay High Court.

This inconsistency formed the central question before the Court – how should the proportionate land entitlement of societies in a multi-building layout be determined where the layout and the development potential available to subsequent buildings change over time?

The Court identified several features of multi-building layouts that contribute to this complexity:

1. the buildings are constructed under different FSI regimes as policy changes over time;
2. some buildings are constructed with base FSI, while some buildings are constructed using incentive FSI (e.g., cluster development, slum schemes, IT parks), which was not available to the buildings constructed earlier;
3. developers re-sanction and revise plans midway through the development of a layout, often after the first building’s society has already become entitled to conveyance;
4. only the plinth area (rather than a proportionate share of the layout) is conveyed to some societies, leaving little room for future redevelopment.

These factors make it difficult to determine how the underlying layout land should ultimately be apportioned between societies formed at different stages of development. The key issue is therefore whether a society’s entitlement should be determined with reference to the eventual development of the entire layout, or with reference to the development position when that society’s right to conveyance accrued.

The Court’s key determination was the point at which a society’s proportionate entitlement to the layout land becomes fixed. The Court examined the developer’s obligations under Sections 10 and 11 of the Maharashtra Ownership Flats (Regulation of the Promotion of Construction, Sale, Management and Transfer) Act, 1963 (MOF Act), read with Rules 8 and 9 of the Maharashtra Ownership Flats (Regulation of the Promotion of Construction, Sale, Management and Transfer) Rules, 1964 (MOF Rules) respectively.

Under Section 10 of the MOF Act, the developer must take steps to form a co-operative society or company within the prescribed period once the minimum number of flats required for the formation of the society/company have been sold. Rule 8 of the MOF Rules prescribes a four-month period for this. Once the society is formed, Section 11(1) requires the developer to convey its right, title and interest in the land and building to the society within four months of the society’s formation.

The Court held that once these prescribed periods end, the society’s proportionate entitlement to the layout land stands “frozen” or “crystallised”. The relevant entitlement must be determined with reference to the sanctioned plan applicable at that stage. A subsequent revision of the layout or deployment of additional FSI or TDR for later buildings cannot, by itself, dilute the entitlement that has already crystallised.

The effect of the doctrine of freezing or crystallisation is therefore to establish a point in time at which the land entitlement of an earlier society is protected against subsequent changes to the development of the larger layout.

This protection, however, is not absolute. The Court recognised that where societies of earlier-constructed buildings have given their written consent to a subsequent revision of the plans, the division of the layout land will proceed in accordance with the revised plans.

The Court’s approach also affects how subsequent development of the layout is communicated to flat purchasers. Where a developer proposes to construct subsequent buildings using incentive FSI/TDR, purchasers must be given adequate notice of the potential implications for the society’s eventual land entitlement, including the possibility that the proportionate land entitlement may be lower relative to the built-up area (BUA) utilised by the building. This is particularly relevant where the development of the larger layout is phased, and the extent of land attributable to each building may be affected by subsequent development. The judgment provides that the conveyance must be undertaken in accordance with the plan frozen at crystallisation and not total BUA. Therefore, a TDR heavy building’s purchasers may get proportionately lesser land than what they would otherwise be entitled to.

The question of what is actually conveyed to the society is equally important to preserving this entitlement. The Court disapproved of the practice followed by the Competent Authority under the Government Resolution dated 22 June 2018 (2018 GR) of conveying only the ‘plinth and appurtenant area’ of a building in which TDR has been utilised for construction within the layout. The Court held that this approach would undermine the objective of enabling societies to undertake future redevelopment by fully utilising the available FSI. Consequently, the crystallisation of a society’s entitlement would have limited practical value if the subsequent conveyance did not adequately capture the land and development potential associated with that entitlement.

This has a direct bearing on redevelopment. The judgment indicates that a society’s entitlement should not be understood merely by reference to the physical footprint of its existing building. Rather, the conveyance must preserve the society’s proportionate interest in the layout land and the corresponding development potential, so that the society can utilise the available FSI/TDR when it undertakes redevelopment in the future.

Developers undertaking phased layouts should consider the potential impact of an earlier society’s crystallised land entitlement before revising the sanctioned plan or deploying additional FSI/TDR in subsequent phases. The judgment indicates that subsequent development cannot, by itself, retrospectively reduce an entitlement that has already crystallised.

Accordingly, project planning and documentation may need to account for:

1. the date on which each society is formed and the point at which its conveyance entitlement crystallises;
2. the sanctioned plan applicable at that point;
3. any subsequent proposal to revise the layout or deploy additional FSI/TDR; and
4. whether the relevant society has provided written consent to such revision.

The Court’s direction on notice to purchasers is also significant. Where subsequent buildings are proposed to be constructed using incentive FSI/TDR, developers should clearly communicate the potential relationship between a building’s built-up area and its proportionate land entitlement. Accordingly, developers seeking to reserve their right to revise plans and protect their entitlement should incorporate relevant clauses in the agreements executed with purchasers, securing their express consent to revise the layout and load incentive FSI/TDR with future buildings shown. For any building utilising incentive FSI/TDR, the agreement and marketing material should set out the FSI breakdown and explain the manner of determining land entitlement so that flat purchasers are aware of their entitlements.

For societies, the judgment provides a clearer basis for asserting proportionate land entitlement in deemed conveyance proceedings. In particular, a society whose entitlement has crystallised should ordinarily be able to rely on the sanctioned plan applicable at that point, irrespective of whether the society has consented to subsequent revisions to the larger layout.

This may be particularly relevant to societies considering redevelopment, since the extent of land conveyed may affect the development potential available to the society. The Court’s rejection of a purely plinth-area approach as per the 2018GR, reinforces the importance of considering the society’s proportionate interest in the larger layout rather than only the physical footprint of its existing building.

The Court has also clarified that a society seeking conveyance in accordance with its crystallised entitlement need not first approach a civil court. It may directly approach the Competent Authority, which will apply the guidelines set out in the judgement to ensure conveyance of the society’s frozen/crystallised entitlement, except when consent has already been obtained. If any dispute persists regarding the existence of consent for revision of plans or contrary land entitlement, the society may approach a civil court. This may make the deemed conveyance mechanism a more accessible route for societies seeking to enforce their entitlement before the Competent Authority.
