Definiţiile pentru "cash bond" care circulă pe net nu prea au nici o legătură cu finanţele şi băncile:
A cash bond is the amount of money that must be given to a court of law to secure the release of a defendant from jail while the case against the defendant is pending. Judges order cash bond as an incentive for defendants to show up for court hearings and their trial. If they fail to appear they lose the cash bond. Judges typically require higher cash bonds for more serious charges.
