If a builder fails to deliver possession by the date promised in your sale agreement, you have strong statutory protections under the Real Estate (Regulation and Development) Act, 2016 (RERA). Under Section 18, if a project is delayed, you have the absolute right to either withdraw from the project and receive a full refund with interest or remain in the project and claim monthly interest for every month of delay. Builders cannot hide behind vague clauses or unauthorized extensions. If you face such issues, consulting a top criminal lawyer in Pune can help if there is evidence of fraud or systemic cheating. For dispute resolution, you can file a complaint with the state RERA authority under Section 31 to seek compensation or a refund. If the matter involves complex contractual breaches, a top criminal defense lawyer in Pune can advise on whether to approach consumer forums or initiate a civil suit. A top criminal law expert in Pune will ensure your documents—payment receipts and the original agreement—are properly presented, while a cyber crime lawyer in Pune can assist in authenticating your digital communications under the Bharatiya Sakshya Adhiniyam. Taking proactive legal action is the only way to hold builders accountable and safeguard your investment.
