H has said 3 times in past month how much he would treasure a move to Europe (Germany or UK) to work for his company's European HQ offices. (His company is HQ out of Germany, he works for the US office currently). He is pushing to be transferred there.
He has worked over there 3 separate trips since Jan. (Also took vacation time there that he didn't tell me about... YD told me he was vacationing 2 of the 8.5 weeks that he was there)

H and I have been separated, but in same house for 4 yrs... I found papers where he had been to an attorney this week.

My mother thinks that he is pushing to transfer to Germany/UK home offices to avoid paying child/spousal support that he will be responsible for. Does anyone have experience with this topic? Can paychecks be automatically garnished overseas companies like they are in the US?

I am hoping that my mother is misinformed on this topic... but I am certain that H would dodge paying anyway that he can.
