I was hoping to hear from you by now to find out what your question was. I am guessing, however, that what you want is your bond money back and you are asking how to get it.
A bondsman puts up the whole amount that was called for, in order to get someoen released from jail. The surety, which is what you are, only pays the 10-15% fee required up front. You pay no more so long as the person doesn't get rearrested or violates the condition of his bond. When the case ends, however, you don't get back the percentage that you paid the bondsman. That's his fee for the loan of his money, which enabled the release of the defendant.
Bail is different from bond. If you paid bail, you paid the court or his holding facility all of the amount that was set at his arraignment. Once the case ends, if there's no violation, you get it all back.
I think this is probably what you wanted to know, but if not, please reply on this question thread and I will expand my answer.
