My sister is getting married and her fiance wants to adopt her her son from a previous relationship. We were talking about the adoption and it came up that I had never listed a father on my dd bc. If I were in my sister's shoes would a guy have to adopt my daughter or could I just add a name? Would he have to take a DNA test to add it or would they take the guy's word? Anyone know how this works? I'm in Kansas if it helps.
