Mr R and his unlcle S applied for a birth certificate of my grandson. They did so in muncipality F and based on false affidavit showing flase place of birth as F and false father's name as R. In real the child was born at place B in govt hospital and his real father is my son S. Mr R is new husband of my ex daughter in law. About this I filed a complaint in police station at place F. After several reminders at last the police registered the FIR under sections 420, 467, 468, 471 and 120B. Now Mr R and S are requesting for settlement and compromise. They are ready to give my grandson's custody to his real father. What should I do? Can I go for compromise without any future risk to me? How the compromise should proceed legally?
