We had talks with the opponent lawyer and said that our client is not willing for 13B.
Her lawyer immediately replied that her client will initiate criminal proceedings against our client under sections 495, 420 etc. and she will definitely prove that her 1st marriage was not performed as per rites and ceremonies and further prove that our client's 1st marriage was performed in accordence with hindu rites and ceremonies and certainly punish him with 7 years imprisonment.
The Opp. lawyer further said that though our client explained that his 1st marriage was dissolved by divorce decree and being social worker associated with law (LLB degree holder) he made to belive her that he has become 'legally single' and competent to marry her and married her. Further he also perused her divorce deed and opined that she also legally competent to marry him. She being the lay person could not able to understand the legal position and believing that she is entering into a valid marriage and married him. Ofcourse these are all false, for which we have the lady's own records to establish she did not submit any documents about her 1st marriage. All that said at the time of marriage was that she was a legally divorcee and till marriage her perents did not submit any records and they blessed the couple to live as fresh couple by ignoring the past bitter incidences.
Besides that she will initiate proceedings under Domestic Violence Act against our client and complain the matter to Bar Council for disciplinary action.
This is the critical point now. Our client is fearing for the unwanton criminal proceedings.
