So you are telling me that the Uncle paid the 50 grand to the Nephew and no money was paid to the jail? Is that how it works?
After getting the $50,000, the Nephew gives the jail $500,000 to release KC . The Nephew gets the $500,000 back when KC is returned to jail/court. If KC runs, then the Bondsman/Nephew would loose the $500,000 until she is caught and returned to jail. Bounty hunters make their living by catching them and returning them to jail. They are paid by the Bondsman , because they NEED the person returned to the jail, to get their money. In this case, $500,000.
The Jail doesn't make money on the deal. The money is just to make sure the person returns for their court date.
