You are lucky. The marital Law in India is gender biased for woman.
So, you can easily convince judge to transfer your case.
If you are working and/or well educated, you will not get any maintenance.
Court will decide how much your husband has to pay for his own lovely son.
Normally it is 1/3 of his salary.
Your husband will file case to see his son.
Please allow him to see his son as otherwise it will be injustice to your son.
Your son cannot file case on you for preventing him from meeting his father, ie. your husband.
The above is the legal answer.
Following is a suggestion.
If you still have some love and trust left on your husband,
and if you love your son and if you think your son needs his father,
then win your husband and his love back with the help of your beloved parents and elders.
Marital life is precious.
Oh my god.
The wife first labelled her husband and his parents as criminals.
She sent them to jail. Now, she does not want the "life" with her husband.
But just wants "Stridhan".
She wants to transfer the case [in a very easy way] so that her husband and parents suffer travelling to her place all the time.
And she wants money [a % of his salary] from a criminal and lying husband?
How will the lying and criminal husband give money to her?
She also separated her son from his father.
Now her son will miss his father? How kindful mother she is.
