Not as an attachment, but can be deducted from the account where the support has been deposited.
It is a separate case, but 50% will be added to any support payment to go toward arrears.
Child support can be taken from any and all available income sources, to include inheritance.
It's possible, e.g., that one number is being used to track support owed to the other parent and a separate number to track support owed to the State(s).
Support that was unpaid at the time of closure is still owed.
Most jurisdictions separate child support matters from other civil suits. In any case, I suggest that you contact your State's child support agency. They have ways of collecting unpaid support.

Child support and child visitation are separate matters. Dropping one does not automatically mean that the other is also dropped.
Contact your State's child support agency, or the venue that issued the order.

You should know how much you are paying in Child Support and it sounds rather odd they would take it off your pay check and your checking account unless you aren't making enough money at work to cover Child Support. If this is the case, then yes, they can take that money from you. You should know exactly what you have to pay re Child Support and keep tabs on what is being taken off of your pay check, plus your checking account. You have the right to demand receipts to be sure the Child Support is going directly to your child or children.
Contact the office with your case file and let them know of the error.
