What Gurugram buyers miss about builder legal track record

Okay, I'll be honest — I thought upgrading from my 2BHK in Sector 82 to a 3BHK or villa on Dwarka Expressway would be straightforward. It's not. I'm looking at places around ₹3 Cr+ in projects like Sobha International City, and the legal due diligence is stressing me out. After hearing about older Unitech issues, I'm super cautious. How do you guys *really* check a builder's legal track record before investing? Beyond just RERA registration, what specific red flags should I watch for in the builder-buyer agreement that favour them completely? My main concern as an investor is title clarity and how any legal mess affects future exit options. Are there specific steps for verifying title most buyers skip? Any advice would be great.
