My question involves name change laws in the State of: New York
Okay, this is kind of a complicated situations, but here goes. When I was born I was given my mother's last name. Now I would like to change my last name to my father's last name, now deceased, and the same last name as my older sister. This isn't what I'm worried about. I have given birth to a daughter and although her father is on the birth certificate, I gave her my last name. I would like to change her last name to my father's as well because the reason I gave her my last name was so we would have the same last name. My question is: should this be a problem? Will her father have to consent although I haven't spoken to him in over three years?
