Noida Extension: Legal checks for new investors?

Greater Noida West – kaafi projects dekh raha hoon, but legal side ka darr lag raha hai. I'm eyeing Fusion The Brook, Shrivinayaka Realtech ka project. My first investment hai, toh I'm super careful. RERA registration kaise properly check karte hain aur kya red flags hote hain? Builder ka legal track record kaise verify karein, especially unke old projects ka? Title verification mein kya steps hain jo most log skip karte hain? Koi experienced log hain jo help kar sakein?
