My son's biological father has not been current on his child support payments since 2005 when his parents wrote a check to cover the balance so he could claim him on taxes. For over 5 years he hasn't called or requested to exercise his visitation rights and now that he is living with his parents is determined to send me to jail for moving out of state for 7 months. And has also threatened to take my son and not bring him back. With joint legal custody but sole physical custody does any one know what options I have?
