-after the payment she has closed all the pending cases back in 2015 at the time of divorce.
So my questions are:
-What are the cases she can file now?
-What will be the maintenance amount I have to pay? my son will be 12 coming jan 2019. Do I have to pay the full amount as the mother has selected a very expensive education for my son?
-Can she take my property, FDs, Mutual fund investments?
-If I get an opportunity to go abroad can she stop me?
-Can I ever get access to my son before he becomes an adult?
You have repeated the same questions once again i your subsequent post.
However since you have given clarity this time, the answers will be as under:
1. Since she has already closed all her complaints she may not plan to file any case now, even if she does, no case will be maintainable.
2. You do not have to pay any maintenance amount since you have already paid her a huge amount as one time settlement, let she file a case, you can refuse to pay any on the basis of previous settlement.
3. She cannot claim a share in your properties nor in the FD amount as a right not even after your lifetime since she is divorced and have no rights in your proeprty even at the stage of intestate succession.
4. You can very well go to abroad as per your will and wish, she has no rights to stop you from travelling abroad,
5. you can file a child custody case, let she defend the same on whatever grounds,m she may rely upon, you challenge her reasons strongly since you are the biological father and natural guardian of the child.
