My first Bengaluru property: Legal checks I almost missed

Okay I'll be honest — I completely underestimated the legal side of buying in Bengaluru. I'm looking at a 2BHK in Whitefield, maybe Prestige City or something from Keya Homes, budget around ₹1.2 Cr. Everyone says 'check RERA', but how do you *actually* verify it properly? Is there a specific site or are we just trusting the builder's word? Also, what about title verification? My parents keep saying it's the biggest risk, but the process sounds so complex. Should I get a lawyer involved right from the start, even before booking? And honestly, if something goes wrong, are RERA complaints even effective here, or is it just on paper? I've heard mixed things. Hoping to avoid any major legal hassles before committing. Any advice on real red flags to look for?
