Looking at it from the other guys prospective. One question. Did the other guy actually sign the birth certiificate? If not, chances are when they go after him, he'll request an DNA test and when it all said and done your son will be declare the father. The other point I made eariler is if the other guy signed the BC but was not married and the child is less than 2 years old, there is a chance (probably with a good lawyer) to have the process of the DNA testing and then have the results determine who the bio father is and then proceed from there.
