1. she is not claiming anything for child.
Bit she is claiming the child itself.
2. Further if I will not agree these terms than she will file multiple false allegation cases on me & my parents which again will trouble me ( including time & money).
This does not means you should lose your rights, let she file any case, you can challenge them after obtaining bail.
3. I will not get divorced till this matter is resolved which may take many years.
If you want your child then you may wait
4. is there any evidence which i should collect now & later show to court (after divorce) that I was being pressurized by my wife to sign MCD with these terms so that court will grant me visitation
Better dont sign the papers for MCD with this conditions
5. kindly suggest any trick or idea or method
No trick, just be true to your child.
