False dowry case against me & my brother

yes you can proceed for second marriage.its always better to go for one time settlement and also try to convince your wife to withdraw her 498a complaint

In order not to make the innocent child to suffer for no fault of him, please file a petition for joint parenting. It is cruel to disown your son and not to take care of his holistic growth and development. You bear his expenses directly without paying for his maintenance. If you are sure that, 498a is a false case implanted on you, I suggest you to fight to finiish in the Court itself. Otherwise, the complainant would demand unreasonable and unjustified quantum of alimony which would be far beyond the amount to be fixed by the Court itself. You need to engage a faithful lawyer who does not matchfix with the opponent lawyer. Goodl luck.

since you had sent a talak nama first before 498a case , so 498a should be null and void.  you should have moved to high court for quashing of 498a on this ground however it is too late to go appeal for same

you should apply " speedy trial application" as it is already too much time passed. A confident lawyer is the key for your success , who may not fix the game. if the court denies speedy trial then you can move to supreme court for quashing of entire process. 

Thanks for your valuble suggetion.
