Yes. Anytime bond money is posted, those monies belong to the jurisdiction of the court and can be applied to any outstanding fines, costs, and fees you may have with the court. Sometimes, if the money is borrowed, the Judge may release the bond and require you to pay back the outstanding balance with your own money and not the bond money, but this is rare as the courts see bond money as being secured money and will utilize it when its available to cover outstanding costs.
