I want to obtain a paternity test to find out if my son is biologically my child. My son is now 14 and I have recently uncovered information that my Ex had an affair and that my son might not be biologically my child. I have paid almost 50,000 dollars in child support and I want to know if I can obtain the test and if this becomes reality, can I sue her for the money and emotional trauma this has caused me. Don't I have the legal right to now know the truth?
