Hello harshvardhan, your question is right. arts stream is right to go to law field or i should say to study LLB. there are a lot of subjects which you study in detail and you should prepare for competitive exams also like CLAT and lsat and some more for particular universities or colleges. scoring a good score can get you in a good college and will help you in shaping your career.

I hope this helps. thanks. 

Yes, of course you can pursue law after studying humanities in class 12th. In fact BA,LLB or LLB is a professional course which any person irrespective of which stream he/ she has studied after 10th can pursue it.

There are two formats followed by the Indian education system as far as graduation in law is concerned.

1. BA,LLB/BA’LLB (Hons)/ Bcom, LLB / BBA,LLB: This is an integrated 5 years course and a student just after 12th can join the same. Either you can sit for the Common entrance test (CLAT) which will get you through any of the best National Law Universities or you can also apply to different government as well as private colleges, all conduct different entrance tests.
2. LLB: this is one when you have already done you graduation and you decide to pursue law further. This is a 3 year degree course; and national law universities and a lot of private colleges do not follow this pattern. But a lot of state and central government universities like Delhi University, Calcutta University, Pujab University etc have LLB courses.

If you wish to pursue law after your 12th, the best option would be to start preparing for the Common Entrance Test (CLAT) from your 12th itself because the same has become very competitive these days and a lot of CLAT aspirants start their coaching in the school itself. If you fair well in this exam, you can get an opportunity to study law in some of the best law colleges of the country. The top ones being, NLSIU Bangalore, NALSAR Hyderabad, NLSIU Bhopal, NUJS Kolkata among others.
