My question involves name change laws in the State of: Colorado
When my ex-wife and I were in our final orders hearing she chose to not change her last name back to her maiden name. I just really don't want her to have my last name anymore (nor did I at the time of the hearing). I am re-married now and I am wondering if I can require her to change her last name. She is no longer a part of my family so why would she need to have my last name? She wanted out of the marriage when she filed for divorce but she didn't want to change her name? I don't get it.
