My uncle's Rajkot property legal warning

Krishna Kunj keeps coming up every time I shortlist something. I'm a first-time buyer, abhi tak sirf location aur amenities dekhi hain. My uncle said legal checks are super important, especially for under-construction projects like Ansal API ke. He mentioned RERA check, title search, encumbrance certificate... honestly, mujhe zyada idea nahi hai in sabka. Is there a standard checklist for these legal verifications in Rajkot? Like, which documents to ask for from the builder, aur kahan se cross-verify karwayein? I'm worried about future issues. Should I hire a separate lawyer for this specifically, ya banks handle most of it during the home loan process? My parents keep saying 'builder pe trust mat karo'. Don't want to get stuck later. Any experiences ya red flags jo aap logo ne face kiye hon?
