Builder asking to pay for private club membership

Please file a complaint against the builder in consumer court. That the builder is refusing to hand over possession.

The agreement needs to be in conjunction to the provisions related to society where the flats are being constructed.

The builder, if includes any such provision for example related to club as mentioned, is a clear case of forcing upon you the provisions in matter pertaiing to service sector. 

You may initiate a notice to him citing the entire sequence and ask for his written reply. He will understand the language. 

If he does not respond, we shall discuss at that time.
