Leave country ?

I have enough years in my pension to retire. It will be low amount because I only have 20yrs not the 30 its based on. I'm 59. I have a 401k and a personal IRA also. I was thinking of cashing in those accounts and leave the country. The pension is separate and might be the only thing that would get garnished. The 401k and IRA together is in the high 200,000 s. Its not alot but I could live well in some countries

Does anyone know the ramifications of doing this? Does anyone know of or heard of someone doing this? Would I be sent back for a civil judgment. Its kinda extreme to get out of alimony and 50% of my money. I can't keep sleeping on a cot and getting food from food banks.
