What is the process to file a complaint against a builder for possession delay?

You can file a complaint with the state Real Estate Regulatory Authority (RERA), provided the project was required to be registered with RERA — most residential projects above a certain size fall under this requirement. The complaint can typically be filed online through the state RERA portal, along with your booking documents, payment receipts, and the builder-buyer agreement.

RERA has the power to direct the builder to pay you compensation or interest for the delay, and depending on what you seek, you can either continue with the purchase and claim delay compensation, or, in appropriate cases, seek a full refund with interest if you no longer wish to proceed with the project.

If your booking predates RERA or falls outside its coverage for some reason, you can instead pursue a complaint before the Consumer Commission, since possession delay by a developer is also commonly treated as a deficiency in service. An advocate experienced in RERA matters can advise which forum and remedy fits your specific situation best.
