Frequently asked questions
What are my rights if COSMOS SERENITY PHASE 1 is delayed beyond 31 Mar 2030?
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 COSMOS SERENITY PHASE 1?
The registered promoter entity is COSMOS PRIME PROJECTS LTD, 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 COSMOS SERENITY PHASE 1?
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 COSMOS SERENITY PHASE 1?
The professionals named in the filing: Architect: SHAH GATTANI CONSUTANTS; Architect: SHAH GATTANI CONSULTANTS; Engineer: RAHUL WAGH; Chartered Accountant: VISHAL KHATRI AND CO. 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 COSMOS SERENITY PHASE 1?
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; whether construction progress keeps pace with sales in the coming quarters. The Rs 499 buyer report works through all of them from the filings.
