we live in il. and my son agreed to let his daughter move to missouri.they have now summons him for back child support. they were never married and a paternity test was never taken yet he knows he is the father and his name is on the birth certificate. he did live with her for about 4 months after the baby was born.she is now remarried and she has allowed us to see the baby until the summons. the visitation was ordered in il.can she stop the visitation,my son has not paid any child support since they went their seperate ways which was a year and a half ago. there are receipts where he did pay support when they were together. my question is will he have to pay what they are asking and they also want him to pay for her lawyers fees. in the past since the spilt they never ask for any support. please help!
