New Delhi 3BHK upgrade: RERA aur legal checks kaise karein?

Okay, I'll be honest — RERA compliance aur legal paperwork ne mera dimaag kharab kar diya hai. I'm currently in a 2BHK near Dwarka, thinking of upgrading to a 3BHK for investment. Considering Jay Hind Apartment by Garg Group. Not sure how to properly check unka RERA registration status for New Delhi. Builder ka legal track record kaise verify karein? What specific title verification steps should I take? Meri main concern hai ki legal issues se future mein exit options aur ROI pe impact na ho. Any experiences with Garg Group ya general advice for investor due diligence in New Delhi?
