My ex owes me a substantial amount in community property separation dollars that were agreed to in our divorce settlement in California. He stopped making any kind of payments (partial/full) and went into hiding in Wisconsin. I believe I have found him there and he has since remarried. Can I go after him for the money I am owed? I fear that I may spook him back into hiding if I were to try to communicate with him. This stems from a divorce in 2001. He stopped communicating with me in 2005 I believe.
