I live in Ohio with my boyfriend. I was married to my ex at the time of my daughters birth but no name is on the birth certificate (states mother refused to provide name of husband). In my divorce papers it states that my ex husband is not the father. According to the law my ex is "presumed" the father. My boyfriends father is stating that he has legal rights to our daughter and wants visitation. I believe paternity must be established before he can do anything. Can he force us to get a paternity test if my boyfriend and I do not want to? If my boyfriend and I were to get married would that make any difference? I thought I read if the natural parents are married, the grandparent has no case.
