Delhi University has impressive law courses under its ambit, so you could consider this. Amity Law School in Delhi is also decent. Do not make the mistake of confusing it with Amity Law School in Noida. The Delhi campus is affliated to IPU while the latter is affiliated to Amity University. I would recommend the Delhi campus.
Not to forget NLU Delhi, but it is a rather obvious choice for being the best law college in the Delhi-NCR region. Symbiosis Law School in Noida has also gained traction amongst students recently, mostly owing to the SIU brand. Lastly, although Sonepat isn't exactly NCR region, but it is close. Jindal Global Law School in Sonepat is one of India's best law schools and by far the best private law college.
