Hello
I am really sorry but your question is not quite clear so could you be more clear and have more details so that I can help you because it's really hard to understand what are you exactly asking us?
So please drop a comment below and let me know.
Thank you.

Hello Shalini,
I guess you are asking for low price law colleges and i assume that low price here means less costly in terms of fees. So here is the list of colleges in tamil nadu which are not costly:
1. Government Law College, Madurai
2. Government Law College, Thiruchirapalli
3. Government Law College, Coimbatore
4. School of Excellence in Law, Chennai.
Hope this helps.
Good Luck.
