Which of the following describes a bail bond that may require no upfront payment?

An unsecured bond describes a bail bond that typically does not require any upfront payment from the defendant. This type of bond is often based on the promise that the defendant will appear for all scheduled court dates. Instead of requiring collateral or immediate payment, the unsecured bond relies on the defendant's assurance to comply with the court's requirements.

In contrast, other types of bonds usually involve some form of payment or collateral. A cash bond requires the defendant or a third party to pay the full bail amount in cash. A secured bond often entails collateral that can be forfeited if the defendant fails to appear. A surety bond, while it can sometimes involve a premium that's a fraction of the total bail amount, usually does require some form of upfront payment or arrangement with a bail bond agent to secure the release of the defendant. Therefore, an unsecured bond is distinct in that it allows a release without any immediate financial obligation.
