I suggest that you immediately consult with a family law attorney about the situation that you are writing about. If you disappeared from your family without a trace and were later declared dead by a superior court in this country, you very well could be held accountable for repaying the state where your wife and children were living for receiving any and all state assistance (AFDC) and even social security benefits under federal law.Additionally, law enforcement will also need to speak with you for the reasons why you disappeared in that most likely a missing person's report was filed regarding you by your wife.
