If you like company law then you can go for company secretary which is professional course
there is also mba in corporate law

Both the fields are very different it depends on the field of your interest

Humanities with subjects like Psychology, Sociology, Economics, English will help you. Five year degree courses in Law need some basic knowledge of these subjects, if you are going for B.A. LLB and if you opt for B.Com LLB to go for corporate law, go for commerce stream. Humanities and commerce both are good for Law. you can select the subject which you like to study.

Yes it is a good option. You can specialise in Direct or Indirect tax laws and establish your own practice.

hi think it has good future. . I agree with Rahul regarding VGU

go to mylaw.net, they have variety of online cert. courses.

as far as I know, you cannot have another professional degree with law at a time. so, yes you can give up your law degree or not practice law and go ahead with your career in SAP.
