My question involves name change laws in the State of: Minnesota
My daughter is seven years old and has my maiden name as her last name, but has been begging for me to change her name to my married name. Her birth father does pay child support, but has no custody or interaction with her and never has. Do I need his consent to change her name or to even hyphenate it? She has had a really difficult time since her baby sister arrived and I would like to be able to do this for her peace of mind.
