1. Decide your goal first
Want the flat + delay interest? RERA. Want a full exit with refund + interest? RERA or consumer commission. Multiple buyers together? Consider NCLT only with advice — it’s a blunt instrument.
2. Compute your claim
Delay interest typically runs at SBI MCLR + 2% from the promised date. Put a number on it — vague claims get vague orders.
3. Serve a demand notice
State the promised date, the delay, your computation and a deadline. Send by RPAD/email; keep proof.
4. File and pursue
RERA complaints are decided in months, not years, in most states. Attend hearings with an indexed document set.
5. Execution if ignored
Non-compliance can be recovered as arrears of land revenue; persistent default invites penalties on the promoter.
Good to know: Continuing to pay instalments under protest (in writing) usually protects you better than stopping payments unilaterally — take advice before you stop.
