My father passed away in Jan. He had no contact with his other child in years. Did not leave a will. I was forced by my aunts to list him on the obit.

even though my dad would not have wanted that. I found out he was not listed on his birth certificate. The father is blank. My current attorney did research and found no paternity was established either. I have not heard from him since jan when I contacted him to let him know about his viewing. So my attorney stated they would draft the paperwork not including him for heirship. I signed and we got a court date for me to become administrator. Today she called to ask for 2 individuals numbers who a lady could call to verify information such as marriage, children etc. One person was my aunt who verified I was the only biological child, other person stated a lady my dad was with 40 years ago moved and there was rumors she had a baby but never came back and there was never any other child around but myself so every one figured it was not his. Now the lady is saying he has to be listed as a heir. I thought no paternity & not listed on birth cert he is not entitled to anything? What can I do
