This question involves the state of Florida. I have a 18 month old son. My sons biological father never wanted to be in his life since he found out I was pregnant. I started dating a new man when I was 2 months pregnant. He signed the birth certificate and I gave my son His last name. Up until my son was 14 months he has been in His life. Now he hasnt made any contact. I recently filed for establishment of paternity to the biological father. He hasn't responded within the 20 day period. My question Is what should my next step be and should I file for disestablishment of paternity to the nonbiological father?!
