My question involves name change laws in the State of: tennessee
My seven-month-old son has his father's last name and I am completely fine with that. His father and I have never been married and probably won't be. I have another child, who has my last name. My question is, I don't want to remove the father's last name but I would be interested in adding mine to his birth certificate to where he would have a hyphenated name. Like John wayne Mom's last name-dad's last name. Do I still need his father's consent to do this or is this something I can do on my own since I don't want to take his father's name off? I would just like both my children to have a last name in common with their mother. This is also my maiden name and I've never been married. Thanks for any infomation you have.
