My builder in Kolkata delayed my flat by three years; can I file a RERA complaint?

You can file a complaint before the Real Estate Regulatory Authority established under West Bengal Premises Tenancy Act 1997 and the Real Estate (Regulation and Development) Act, 2016 for delay, defective construction, or violation of the agreement. The complaint should annex the allotment letter, agreement, payments, and correspondence. RERA can direct the builder to refund with interest, complete the project, or pay compensation, and the order is appealable to the Real Estate Appellate Tribunal and Calcutta High Court on questions of law. The builder cannot sell covered areas or alter plans without consent. RERA also requires the builder to deposit the project and disclose approvals. Compensation includes interest for the delay period.
