Noida Extension 3BHK search: legal safety first

RERA compliance in Noida Extension feels more like a suggestion for some builders, honestly. I'm finally upgrading to a 3BHK, maybe around Sector 150, for my growing family. Kids ki security aur future ke liye, I'm super stressed about legal issues with properties here. How do we *really* check RERA registration for projects? Kya sirf portal pe naam dekhna enough hai, ya aur deep dive karna padta hai for red flags? Aur builder ka track record kaise verify karein, like for someone like ASK Developers, jo Paradise Green Plaza ke paas hai? Title verification ke liye kya crucial steps hain jo log aksar miss kar dete hain? Don't want any surprises later, especially with future school admissions for the children. What's the community's take on this?
