My daughter has my maiden name. I am recently married to someone other than her father. I would like for her to have my husband and my last name. How do I do this? This is the only info I have found so far:

Be aware that changing the last name of a minor child does not change the identity or obligations of the child’s father. Changing a child’s last name to match a stepfather’s does not absolve the natural father from paying child support, nor will it obligate the stepfather to pay child support should his marriage to the mother end in divorce.

Doesn't explain if I need a court order for my situation.

I went through this same thing...

My daugther was given my maiden name because her father and I weren't married. I have since married and wanted to change her last name.

You have to get the consent of the biological father in order to legally change the child's last name. And no it doesn't matter that you weren't married to the father, and that the child has your maiden name not that of the fathers... trust me I asked ;)

So you need to get consent from the father. In Ohio, once consent if received there will be a court date and it costs $133... again, that's in Ohio. You should be able to call your local courthouse and get the specifics for where you live.
