OP – you are trying to find a legal solution for an emotional issue. You state repeatedly that you want your birth certificate to reflect your heritage, but truthfully, birth certificates aren’t hung on walls nor shown to others in normal circumstances. Heritage is something that goes deeper then paper. What is the name change on the birth certificate going to truly accomplish? It won’t change who you are. You are who you are. It won’t change your father, biologically. The man that you have found to be your biological father is your biological father whether he is on the paper or not. And moreover, you mention several times that you have concerns about how changing your birth certificate may fracture the relationship between you and your father or your father and his wife. You need to do some soul searching as to why you are rushing into this right now.
I think you would do well to sit down and talk over everything you are feeling and hoping to accomplish with a licensed counselor.
You state these fears about how the change will be handled by your dad and his wife repeatedly.
[ No you shouldn’t.
This man that is your biological father was your biological father at birth and will be your biological father for your whole life. Paper records and court documents can’t make him more or less than what he is. You are eager, and excited, but you mention over and over that your father and his family might not be. Please speak with someone who can help you sort through why you want to do this, especially when doing it puts so many relationships at risk, and only after you are comfortable with the answers should you proceed.
