I received a termination of iwo but they keep garnishing my check whats the next move

Once the Friend of the Court has issued a termination of income withholding order notice, child support should be terminated.  It is possible that the Social Security Administration did not get the income withholding order before.  In otherwords, it could have been received too late to stop the garnishment.  Also, are you in arrearages?  If so, you may not be accruing new child support on a month-to-month basis, but you still owe the arrearages.   I suggest you contact the Friend of the Court and seek a current accounting of your child support.
