What are the ownership rights in a society flat?

Hi,

Typically, after the builder begins a project, he enters into a sale agreement with the buyer. Under this agreement, the builder builds the apartment using the buyer's funds, making the apartment the buyer's property because it was paid for with his money. The builder then transfers the land into the name of the newly formed Housing Co-operative Society, which subsequently issues share certificates to the buyer for the proportionate share of the land. By following this process, the buyer acquires both the apartment and the undivided proportionate piece of the real estate. The builder agrees in the contract to grant use of accoutrements and extensions; ownership of these items is not granted; just use of the items is granted.

So, the entire ownership of the flat under a cooperative housing society falls under the buyer only.
