RERA registration for Ansal API is just a formality, right?

Is Ansal API's RERA registration for projects like Ansal Aastha Mig Zone near 150 Feet Ring Road really enough protection? I'm in real estate myself but buying for me is different. What real title verification steps do you all follow in Rajkot that most buyers miss? Honestly, I'm worried about builder delays, especially for a 3BHK around ₹90L. If they default on possession, what are the actual legal options under RERA here? Is filing a RERA complaint effective or just a long process with no real outcome? Share your experiences.
