Changing an Adult's Name: Changing Last Name While Abroad

Hello.
I'm a US citizen living abroad for the past 20 years.
I realize that in order to change my name, I need to show up in court in the county I reside in, etc.
Is there any way to do this without having to be physically there?
I could travel over to do this, but it's practically impossible to arrange the necessary accommodations to whenever I get the court hearing date.
Surely there has to be a way.
I've called my local embassy and they just told me to call my local court directly. :wallbang:
Any ideas?
Thanks.
