I'm not exactly a single mother, but I'm trying to be very open to what the future could bring. I'm pregnant, and want to give my coming-soon daughter her father (my boyfriend's) last name. Recently, some people have been telling me that by giving a child the father's last name, it can lead to child custody and other legal issues in court if we split up. Is this true? He's going to be an awesome dad no matter what, but it would mean alot to him if she had his name. I really want that for her, but not if it's could cause major issues in the future.
