Thank you for the advice. I plan on having it served to him at his last known address he doesn't let anyone know where he lives currently. I want to try regardless if they deny. My daughter is going to keep his last name so I feel what more should he want from me. She should be able to use the name that those that care about use.

To the other poster I don't think she can use the usage name in that way because it isn't part of her name. I want to add it and make the first name her middle name keeping the last name. I want the change because she is starting kindergarten and I want her to spell the name she is called on a daily basis by everyone.
