Hello Yogesh!

You have already completed BE Civil Engineering, so go for LLB directly. LLB is a three year course and is more preferable other than the diploma courses, as you would grab more internship opportunities in law firms and get self employed easily. You do not need to go for BA LLB as it is an integrated course and is of five year duration.

I would suggest you to go for LLB in Construction Law. Because it would be the most suitable course according to your civil engineering background. I suggested this specialization because most of the construction companies and real estate firms have civil cases nowadays. They have many disputed lands issues and many other issues also.
