So in this case the mother kept the child's existence from the biological father (who I will refer to as John). No paternity test has been performed yet, but the mother knows without a doubt that John is the father. John now knows about the child and rightly suspects it is his. John has contacted the mother and has said he that he is going to sue for custody as well as pain and suffering, as well as fraud.
Another issue is that the child already has a legal father in their life that is on the birth certificate. He has known from the beginning that it's impossible for the child to his biologically. However, he loves the child though and is very involved in their life. Furthermore the child (who is now 15) has been aware of all this for several years and has no interest in meeting or knowing John at all and is frightened by the prospect of him having any custody.
