Family/criminal lawyer support required

Mr.A case (myself): - 1st marriage with ex-wife on Oct 2012 - No dowry demanded or accepted from ex-wife's family - Our Baby born on Dec 2013 - Ex-wife filed false Dowry case FIR on me & family on Nov 2014 - I have filed Conjugal case in family court in Nov 2014 - Applied bail in session court and received Anticipatory bail for all family members from session court on Sep 2015 - As per muslim law, sent 3 Talaq notices on Nov& Dec 2015, and Jan 2016 to Ex-wife - Women's police station filed charge sheet on June 2016 - Currently attending Dowry case in sessions court and simultaneously filed Quash petition in High court for family members Ms.B case: - Ms.B got married to my ex- brother-in-law on Oct 2014 - Ms.B filed DV case and Dowry FIR against my ex brother-in-law and his family on Feb 2015 - My ex Brother-in-law filed Conjugal case on Feb 20, 2015 - Ms.B and my ex brother-in-law's baby born on June 2015 - My ex Brother-in-law sent Talaq notice to Ms.B on Oct 2015 - Currently DV & FIR case is running in court against my ex-brother-in-law and his family (i.e my ex-wife's family) Myself & Ms.B (Currently married) - With family's consent, myself and Ms.B got married on Feb 2016 (after proper divorce notices with both our ex's) Situation: - Considering my current wife's (Ms.B's) baby future, marriage certificate for myself & Ms.B were registered in registrar office dated Feb 2014 (but correct marriage date is Feb 2016). As a proof, original Nikhanama (marriage doc issued by religious body) of myself and Ms.B's is available. But for marriage registration purpose, support documents including duplicate nikhanama with incorrect dates were produced at registrar office. Queries: - My ex-wife's family might get hold of marriage certificate of myself and my current wife which has incorrect date, and could produce in court. - How to proceed with my Dowry case and Quash petition case in sessions and high court? if incorrect marriage certificate is produced. - Is there anyway the marriage date could be corrected/cancelled in registrar office? Registrar isn't agreeing to change marriage certificate as support documents which were produced carries incorrect date too. - Should New marriage certificate be applied for myself & my current wife (Ms.B) with correct marriage date at different registrar's office? Is this feasible option? - Can i file a suit in court to direct registrar to modify the marriage certificate? We understand that marriage registration with incorrect date is lawfully wrong, but were emotionally driven at that time, considering only the baby's future. Now, we know the consequences. I am the only bread and butter for my old aged parents, and with my father handicapped person, currently false Dowry FIR case is on-going in court. I sincerely request detailed legal advise on this. Thanks to everyone.
