The best way to ensure that all payments you make are recognized by the court towards the arrears is to make the payment directly to the Child Support Enforcement Unit instead of just bringing money to court. If you are concerned that the payment will not reach the Child Support Enforcement Unit before your court date and reflected in the account balance statement, then you should bring the payment (as a money order), at which point the court will normally ask the petitioner whether they are willing to take the payment directly and have the court recognize and inform the Child Support Enforcement Unit that payment was made, or whether the petitioner prefers that the payment is sent directly to the Child Support Enforcement Unit.
