Hello Vaishali,

If you are willing to persue MBA in business law then for that you need an under graduation degree with minimum of 45% marks. 

After your undergraduation you need to figure out which are the best B-schools in India and abroad, what are the eligibility criteria for getting an admission and what exams you neeed to qualify in order to get an an admission(e.g CAT, GMAT, SET etc).

When you are done with your research you need to prepare for the exams and wait for the results. If your result is suitable with the cutoff list of the college you are looking for than in that case you can apply for in that particular college and accordinly they will call the suitable candidtes for an interview round and finally give the admission to the desired candidate.

Wish you all the best.
