Once actual arrears balance is paid in full can child support agency still continue to use administrative measures such as income withholding, liens, etc. to collect the remaining interest? If so, can they continue at the full monthly amount or can I ask for a lower payment plan? Or is there any way to ask the court to forgive the interest owed to the custodial parent? Or if it can't be forgiven then change it so the money is actual is received by the children since they stopped living with the parent before they were 18 and have had no contact with the parent receiving the money? Custodial parent won't return communication about forgiveness? Also have younger children under the age of 18 with a second family that I would prefer to switch this support to.
