You are seeking legal advice. Perhaps it may help if you shed some light on where this marriage was solomnised, temple, church, mosque ? In India or outside India. Is your husband alive , sane and capable of raising children ( not impotent )?
If you dont obtain divorce and marry, that would constitute bigamy, something the Indian legal system does not appear to have tolerance for.
To educate myself on the ibid topic, I looked up India Kannoon and found a case that may befit your situation. If you proceed ahead with marrying someone, you may be charged under 494 IPC and get upto 2 year RI.
1. I am not a lawyer or authorised to practice law. Dont based your decisions on my reply.
2. Your handle appears to be masculine ( sai ram ) and your descripttion is more manly ( stud). What are you trying to hide. Are you trying to dump a women and run away ?
