My first investment, but legal doubts are killing me

Everyone glorifies RERA as buyer protection, but honestly, is it just for show? I'm looking at options like Vatika Primrose Floors. Builder ka track record kaise check karein for legal issues, especially with names like Eka Life ya Dhoot Group? Title verification steps... people skip them, right? What happens if RERA registration mein kuch gadbad nikli? Kya RERA complaints actually effective hain ya sirf paper pe? Gurgaon mein toh lagta hai sab chalta hai. Disagree? Tell me why.
