We both have my maiden name as a middle name and we were annoyed by the $350 plus a court appearance. The ladies in the court office were all excited for us that he was changing his name but then the female judge was not amused.  Here is how it went.

Judge: "You want to change your name from __ to __?"
DH:  "Yes."
Judge:  "You do realize that this will not get you out of any legal or financial obligations that you may have."
DH:  "yes."
Judge:  "You do understand that your identity will remain constant."
DH: "yes."
Judge:  "Then why are you changing your name?"
DH:  "Well, you see I have a new wife and..."
Judge:  "Oh, I see.  One of those new age marriage agreements.  Ok, see the clerk."

It's funny now but at the time when the judge was looking down on him from her perch with a disapproving glare, not so funny.
