CA Company Secretary

The choice purely depends on the ultimate goal that you have set in mind.
Actually, the course content plays a very huge role in deciding the best match with law. CA course although can be a good choice. However, the context of the syllabus is quite different from that of law. The similarity between, both CS and LL.B. is that both of them are law focused courses. The CS curriculum attempts to make you study corporate laws in depth, whereas an LL.B. course will make you study a number of laws ranging from civil to criminal.
If we now consider the fact, that you want to primarily be a CA, and then pursue a degree (CS or LL.B) that is law focused, I would suggest that you would like to practice in corporate law and tax law matters as a Chartered Accountant. If that is true, I would suggest going for LL.B. as an additional degree because a CA or a CS cannot represent his client before the High Court or the Supreme Court. So, in case you grow in your profession and would want to litigate before these courts, you would need a membership of the Bar Council, for which an LL.B. degree is a pre-requisite.
