They have been divorced for 3 years and she still holds her married name. But in their divorce papers, she didn't ask to be granted her maiden name. Is there anything we can do?
If the order doesn't specify that she take back her maiden name, she can continue to use the married name. He can't force her not to use it, and it's up to her. Just like it was up to both of them if anyone would change their name when they married.
