Well, there's yet another good reason to stick with local credit unions whenever possible. If they have no presence in another jurisdiction, they're unlikely to comply with any of that nonsense.
The advice I was given (not by the CU): either withdraw all my money from the account and put it in a safe deposit box, or wire it to a (very) close relative ASAP -- before the lien is officially issued.
IT is generally too late. Both are problematic and can be clawed back relatively quickly (the timing looks suspicious, etc). Yes, they would have to take you to court, but the defense costs usually exceed the asset value (and the author notes this).
I'm a little too paranoid to say exactly what I did, but I will say that I'm glad I was given that advice. (I was younger, and had much less money saved at the time; obviously that amount would affect any similar decision now.)
