To get right to the point, my fiancee' passed away from a accident at work while I was 4 months pregnant. We have a 2 year old daughter together and he also has a older daughter with another women. This was back in june and I was unaware that once my son was born that I would have to prove who his father was. I am trying to get his father added to the birth certificate (which is like pulling teeth) and I also would like to add his to a SS case that is already open for the girls. I have already been denied once for SS (adding my son) and now I have to appeal and I am hearing that a sibling dna is still not 100% because I am proving siblings not father. He does have a brother but we have since had a falling out and he would no willing help with his dna. Is there any way or process I can take to where I can at least put my sons father on his birth cert?
