Before my husband was divorced his wife had a child as the result of an affair. This child has been brought up by her biological mother and father apart from the first few months but my dh is listed as father on the birth certificate as he was unaware of affair at time of birth. The child is now an adult but still has wrong father on certificate. What are the legal ramifications when my husband passes away. He has two older children from that marriage and younger ones with myself.
