Can redevelopment of two adjacent societies be initiated without formal merger ?

A redevelopment of two adjacent housing societies can be done together, but it is a complex process that requires careful planning, legal considerations, and approval from relevant authorities, often involving the amalgamation of the societies into a single entity to manage the joint redevelopment project. 

Combining multiple societies for redevelopment might require legal procedures like canceling existing registrations and registering a new joint entity, which can be time-consuming and involve potential disputes over property rights and FSI allocation. 

Both societies need to hold special general meetings and obtain a majority vote from their members to agree to a joint redevelopment project. 

Combining projects can lead to cost savings due to larger development size and potentially better deals with developers. 

Joint redevelopment can allow for more efficient use of land and potentially better overall design for the combined development. 

Differences in opinions regarding development plans, desired amenities, or distribution of benefits can lead to conflicts between the societies. 

Any disagreements during the process could lead to lengthy legal battles.
