RERA compliance in Noida Ext: What am I missing?

₹85 lakh for a 3BHK in Noida Extension seems fair, but I'm worried about legal clarity. I work in real estate, but buying for myself is different. How do you *actually* verify RERA registration for projects like Gaursons Atulyam? What are the key title verification steps people often miss? Should I be extra cautious with Aradhyam Builders? I need solid advice on preventing future RERA-related headaches.
