Demand of membership fee of 25600 from builder for the flat they sold

Dear Client,
Your query is a little bit confusing. Membership fees are charged by the society from the buyer who bought the flat from a Builder. A builder is not considered member of a housing society. So, it appears that you might be talking about transfer fees that levied by the society on a transfer by way of sale of flat by the flat owner. Model By Law No.38 allows the society to charge a maximum transfer premium/fee of ₹25,000 when a flat is sold by the owner, which is collected to cover the basic administrative cost and record update. Bye Laws Nos. 172, 173, and 174 of the Model Bye-Laws of Cooperative Housing Society deal with the redressal of complaints of a member of a society registered under the Maharashtra Co-operative Society Act, 1960. As per Bye Law No 174(a), Complaints may be made to the Registrar of the Cooperative Societies, failing which complaint may be filed before the Cooperative Court under Bye-Law No.174(b) and failing which, the aggrieved person may file a civil suit before competent Civil Court under Bye-Law No.174(c) of Model Bye-Laws of Cooperative Housing Society seeking appropriate relief in the matter. If required, seek the opinion and service of legal professionals to navigate the issue in the right way.
