I guess my questions here have to do with goals, motivations and a bit of a reality check.
I completely get the frustration at not receiving the court-ordered (it is court-ordered, right?) support. I fully understand trying to use whatever methods are available to get what the court says you are due.
I'm wondering, though, of what value it is to have his license suspended, thus ensuring that he is unable to work, unable to earn money, and thus unable to provide the support that you're looking for this to shake loose.
In other words, while this may be an available option, I question whether it will provide the desired result.
