Which of the following is a consequence of failing to comply with a bond?

Forfeiting a specified amount of money is a likely consequence of failing to comply with a bond. When an individual is issued a bond, it is generally to ensure their appearance in court or to comply with conditions set by the court. If the individual fails to meet these conditions, the bond can be forfeited, meaning the amount put up as collateral for the bond is lost to the court. This serves as a financial incentive for the individual to adhere to the bond requirements and appears in court as scheduled.

The other options do not reflect typical consequences of failing to comply with a bond. A warning may be given, but it is not the primary consequence. Appearing before a judge may occur, but it does not directly correlate to the failure to comply in the same manner as forfeiting the bond. Lastly, appealing the bond requirement is a separate legal action and not a consequence of non-compliance. Therefore, forfeiting a specified amount of money is the most fitting consequence in this context.
