She’s an adult so the name change is up to her to do. She needs to file a petition in the probate court in the county where she resides (assuming she is in Ohio). The Supreme Court of Ohio has adopted a name change form she will use for that. She must also be sure that she has published her intent for the name change at least 30 days before the court hearing on the name change. She can Google the name of her county and "name change" and she may get specific instructions for the probate court her county. If she has any questions, she can ask a family law attorney. The process is pretty straightforward though.
