"Now Samir you give me an argument to discuss with his lawyer so that i don't lose - I need your help that's why i am here!"
First, you need to keep your approach as simple as possible, but no more. Unfortunately, parties get carried away by the whims and fancies of their advocates and advice they get from half-baked advocates or worse, non-advocates like me!!! Very soon there is a plethora of cases files, applications made without any specific end-goal in mind and the litigation becomes a mess - the litigation file gets a foot tall, new advocates shy away from such cases or ask astronomical figures to take the case. For advocates who create such situations - this is orgasmic. You are stuck with them for the long run and long it sure will be...
Another advice for a woman in matrimonial litigation is that THREAT IS MORE LETHAL THAN ATTACK. The hint that you are considering the filing of various cases can be leveraged a lot more than actually filing the cases... No advocate will give you this advice. Reason? A clear conflict of interest. Be assured that if you file DV, 498 and other such cases, you are digging a hole for him in the short-term but a real deep one for yourself. Just threaten that you can and that you will file, if required. But never file any case other than one seeking maintenance and divorce, if you absolutely must.
Strike when the iron is hot. Once you have threatened to file cases, the iron is hot, proverbially speaking. Your threat of filing cases will slowly lose their heat as time passes on. So, try to close a settlement without getting too greedy... Be realistic... understand what is really doable and reasonable for him.
"Threaten" when talking to his advocate : When you discuss with his lawyer, you need to present to him what you can get from the Courts... Tell him that your husband is stuck with litigations for the rest of his life because you will always be seeking for higher maintenance no matter what is ordered now simply because you are entitled to one when circumstances change and circumstances change all the time... Tell him that the day he marries another woman, you will make sure that every event is a "change in circumstances..." Then, rattle all the cases that you can possibly file against him... In short, hint that you can make life hell for him...
But guide him towards the better option: But... Then, tell him that you are not that type of a person. You want him to lead a good life, his way as long as he takes good care of you and your son... Tell him that there is an alternative that he can choose... He can live in comfort... become ambitious... earn and enjoy... have girlfriends, wives, lovers, whoever... if only he can give you a one-time lumpsum settlement and both of you part ways amicably... You will consent to a mutual agreement divorce... You will even let him visit his son... All this will be part of the settlement and that you will wish him good luck for the rest of his life... and from the bottom of your heart...
I am advising you with this approach because I believe that this leads to a win-win situation for both sides, provided the husband gets a top-class advocate to draft his settlement and not just rely on free advice from a smartass like me -:)
As for all the advice on God, morality, faith, fairness and other such discussions, I think that even the Gods stay away from Courts... Just keep your reasonable objectives in mind and work towards them and only towards them sans emotions. Gods have no role to play in the Court system. I am not sure that they have a role to play in any system but that is not what we are discussing here.
THIS IS MY FINAL CONTRIBUTION TO YOUR QUERY. I HOPE OTHER WOMEN ALSO READ IT AND FOLLOW IT. GOOD LUCK!!!
