Q 1. If we will abort the baby, is there any action further taken by her ?
How can you abort the child without her consent, in fact your pressure to ask her to abort the child will lead to more complication to you including a criminal complaint before police.
Better do not try any such gimmick.
Q 2. And If i will marry another girl now.. Is she sue DV or maintenance or Set aside ex-party or send me recall notice or i will go for punished by law (tell me answers with reasons please) ?
If the period of 90 days has expired then you can go for re-marriage.
Setting aside the exparte decree or filing a DV case is her right or decision.
