1. Voting Rights in a Condominium Meeting: Voting rights in a condominium meeting are typically determined by the provisions outlined in the Condominium's governing documents, which often include the Deed of Declaration, Bylaws, and Rules and Regulations. The specific rules regarding voting rights may vary from one condominium association to another. In many cases, the number of votes may be based on unit ownership, not the number of people present. You should review your Condominium's governing documents and consult with a legal expert to understand your specific situation.

2. Annulment of the Condominium: Annulment of a condominium is a complex legal matter and typically requires a significant legal process. To determine whether annulment is possible, you should consult with an attorney who specializes in real estate law and is familiar with your jurisdiction's regulations. The presence of fraudulently inserted members may be a basis for legal action, but the outcome would depend on the specific facts and circumstances of your case.

3. Conversion of Condominium to Society: The process of converting a condominium to a cooperative housing society can be complex and often requires the consent of a significant majority of unit owners. The specific requirements and procedures for such conversions vary by jurisdiction and are typically outlined in local condominium laws and regulations. You should consult with a legal professional experienced in condominium law in your area to understand the process and the majority needed for conversion.

4. Deed of Declaration and Conveyance: If the Deed of Declaration implies deemed conveyance of common areas and explicit conveyance has not been done, it is important to consult with an attorney who specializes in property law in your jurisdiction. They can advise you on the specific legal remedies available, which may include pursuing legal action to compel the conveyance of common areas or addressing any issues related to the registration of Deeds of Apartment.

Condominium, is a group of housing units where owner of each home owns individual unit space and ownership of common areas is shared by all. Every unit is called “apartment” and owners the apartment owner(s). A condominium is formed under Maharashtra Apartment Ownership Act, 1970.

The said Societies are framed by occupants of structures by the individuals themselves or by a Promoter/Developer.

Residents can come together and register a cooperative housing society. You can do this without the builder.

 You can convert from condominium to society only if more that 50% members are ready for conversion.

In Condominium the Court having jurisdiction over the area in which the Condominium is located hears the disputes.

In a Condominium every apartment owner has voting right in proportion to the value of his premises, which is generally as per the area of the apartment and is defined while forming the Condominium.

In condominium, members of the apartment owners association elect a “Board of Managers” which in turn elects President, Vice-President , Secretary and Treasurer to manage day to day affairs.

Most of the upkeep and maintenance charges depend on the residents of the space. 

A condominium is a housing arrangement where each homeowner owns their individual unit while jointly holding ownership of the common areas. Each individual unit is typically referred to as an "apartment," and its ownership is vested in the apartment owner(s). In the state of Maharashtra, India, condominiums are established in accordance with the Maharashtra Apartment Ownership Act of 1970.

These housing societies can be established either by the occupants of the buildings themselves or by a Promoter/Developer. Residents have the option to register a cooperative housing society independently, even without the involvement of a builder.

In the event that more than 50% of the condominium's members express a desire for conversion, it becomes possible to switch from a condominium to a cooperative housing society. The jurisdiction for resolving disputes within a condominium lies with the court that has authority over the area in which the condominium is situated.

In a condominium, each apartment owner is granted voting rights commensurate with the value of their premises, often determined by the apartment's square footage, as specified during the formation of the condominium.

The management of day-to-day affairs within a condominium is typically handled by a "Board of Managers," elected by members of the apartment owners' association. This board, in turn, selects individuals to fill key roles such as President, Vice-President, Secretary, and Treasurer, who oversee various aspects of the condominium's operations.

The costs associated with upkeep and maintenance in a condominium are generally shared among the residents based on their respective unit spaces, ensuring that each homeowner contributes proportionally to the maintenance of common areas and facilities.
