Frequently asked questions
What are my rights if Promesa Castor is delayed beyond 31 Dec 2026?
Under section 18 of the RERA Act you may stay in the project and claim interest for every month of delay, or exit and claim a full refund with interest. In Maharashtra the rate is SBI's highest MCLR plus 2 percent, currently 10.90% per annum (June 2026). The free delay interest calculator on ReraGenie puts a rupee figure on any delay. Claims are filed as MahaRERA complaints with a Rs 5,000 fee.
How do I verify and contact the developer of Promesa Castor?
The registered promoter entity is DARSHAN GROUP, a company as per the filing. The filing discloses no CIN, LLPIN or GSTIN for this entity. Your agreement for sale must name this exact entity, not a group brand name. The promoter's registered address and contact details are on the project's MahaRERA listing (scan the QR code on any advertisement) and in its filed documents, all downloadable free from this page with a login.
Is my payment protected in Promesa Castor?
Partly, by law. 70 percent of every buyer payment must go into the project's designated bank account, withdrawable only against architect, engineer and CA certificates as construction progresses; since July 2024 MahaRERA requires a three-account structure for collections. Separately, a promoter cannot take more than 10 percent of the price before signing a registered agreement for sale (section 13). Neither rule guarantees completion; they limit how far your money can travel from the project.
Who certifies construction progress at Promesa Castor?
The professionals named in the filing: Architect: Kaushal Chouhan; Engineer: Prakash Bajaj; Engineer: Computer Help; Chartered Accountant: V H KOTHARI AND CO; Chartered Accountant: SANGHVI SANGHVI & SANGHVI. Their Form 1 (architect), Form 2 (engineer) and Form 3 (chartered accountant) certificates are what unlock the promoter's withdrawals from the 70 percent account, so their names on record are part of the project's accountability chain.
What should I check before booking in Promesa Castor?
Four things this page cannot decide for you: that the carpet area in your agreement matches the filed carpet area (the model agreement allows only a 3 percent variation, with a refund right below that); that the agreement follows MahaRERA's model clauses with deviations highlighted; the promoter's record on their other projects, not just this one; why the completion date was revised and what the new timeline depends on. The Rs 499 buyer report works through all of them from the filings.
