I am searching for help with a unusual situation in Pennsylvania. I am an adult woman. I am the offspring of K.C. (an affair my mother had with an old boyfriend) while married to my father J.F. J.F. is listed as my father on my birth certificate although a DNA test has proven he is not biologically related to me. K.C. has never acknowledged me as his child. My mother did write to him an inform him he was my biological parent. He chose not to respond. I wrote to him several weeks ago (he lives in the same city). Once again he has not responded. My question is related to health information. Although I could care less about K.C. and meeting him, I think it is incredibly important to get his health history. I have asked him to take a paternity test and release medical records to me. I believe his health history is also my health history (for better or worse). I think that maybe his father and uncle died at a young age due to heart attacks. (although I am not sure of this) I have had some medical problems recently and would like to be able to share with my doctors a complete medical history. Any ideas on how to proceed with legal action against K.C. Can I force a paternity test and release of medical records? I believe I should have the right to confirm he is (unfortunately) my biological father.
