I had a legal name change a few years ago that cost me $11.00.  Actual physical paperwork had to pass thru numerous paid employees's hands, from the clerk to the judge.  Then I had to take that paperwork to the Social Security office, the DMV and my bank - more paid employees to handle the paperwork and then to update their electronic records.

That name change was worth it.  And that's all I've got to say on the subject.
