If a builder has delayed possession of your flat in Kolkata beyond the timeline promised in your agreement, you have a strong legal remedy available through the West Bengal Real Estate Regulatory Authority (WBRERA), which now governs real estate development across the state after the Supreme Court struck down West Bengal's earlier HIRA framework in 2021 and restored the applicability of the Central Real Estate (Regulation and Development) Act, 2016. Your first step should be reviewing your builder-buyer agreement carefully to confirm the promised possession date and any grace period clauses, since this forms the basis of your compensation claim.

You can file a complaint before WBRERA seeking either possession of your flat along with delay compensation calculated for the entire period of delay, or, if you no longer wish to proceed with the purchase given the extended delay, a full refund of the amount paid along with interest and compensation. WBRERA proceedings are designed to be considerably faster and more accessible than traditional civil litigation, giving Kolkata homebuyers a genuinely effective forum for this common grievance.

Your lawyer will help calculate the compensation you are entitled to, typically including interest on amounts already paid, calculated from the promised possession date until actual possession is handed over or the refund is processed, at rates specified under the applicable rules. It is important to maintain thorough documentation throughout — payment receipts, all correspondence with the builder regarding delay, and any revised timelines the builder may have offered — since this evidence significantly strengthens your claim before the authority.

If the delay has been particularly prolonged, or you suspect the project may be facing serious financial difficulty, discuss with your lawyer whether pursuing a refund with compensation, rather than continuing to wait for possession, better protects your financial position, especially if you are simultaneously servicing a home loan for a flat you have not yet received. WBRERA orders directing refunds are enforceable, and non-compliance by the builder can lead to further recovery proceedings against them.
