Frequently asked questions
What are my rights if Birla Trimaya-Phase-I is delayed beyond 31 Oct 2028?
Under section 18 of the RERA Act you may stay in the project and claim interest for every month of delay, at the rate the state's RERA rules prescribe, or exit and claim a full refund with interest. Claims are filed as complaints with RERA Karnataka.
How do I verify and contact the developer of Birla Trimaya-Phase-I?
The registered promoter entity is BIRLA ARNAA LLP, a partnership firm as per the filing. Its GSTIN 29AAZFB1893R1Z4 can be cross-checked on the MCA and GST portals. 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 RERA Karnataka listing and in its filed documents.
Is my payment protected in Birla Trimaya-Phase-I?
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. 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 Birla Trimaya-Phase-I?
The professionals named in the filing: Architect: V. NARASIMHAN; Engineer: Yogesh HP; Chartered Accountant: Anilkumar R. Gupta. Their 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 Birla Trimaya-Phase-I?
Four things this page cannot decide for you: that the carpet area in your agreement matches the filed carpet area; that the agreement follows the model agreement under the state's RERA rules, 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.
