Final answer:
Appeal bonds usually require collateral such as valuable property or equipment as security, to cover potential costs and ensure financial responsibility if bond conditions aren't met.
Step-by-step explanation:
Appeal bonds, used in the court system, typically require collateral as a form of security. Collateral is something valuable, often property or equipment, that a lender, or in this case the court, would have the right to seize and sell if the bond conditions are not met. This requirement ensures that the appealing party is financially responsible for the potential costs incurred from the appeal, including the original court judgment if the appeal is lost.
