My question involves paternity law for the State of: Illinois
My husband's ex-wife had a child in 2002, while they were married. He has paid child support since 2003, when they divorced. He does not believe he is the father of this child. His name is on the birth certificate. If he requests a paternity test and proves he is not the father, would he still be responsible for child support for the child simply because they were married when the child was conceived and born?
