What is typically necessary for a court to establish in order to enforce a judgment?

To enforce a judgment, a court typically needs to establish an execution. An execution is a legal document that authorizes a law enforcement officer to enforce or carry out the judgment that the court has provided. This can involve actions such as seizing property to satisfy a debt or lien established by the judgment.

In legal terms, execution is the process by which a judgment is enforced, ensuring that the prevailing party can obtain the relief awarded by the court. Without this step, even a valid judgment may not hold any practical value for the party seeking to collect on it.

The other options do not serve the direct purpose of enforcing a judgment. An affidavit is a written statement confirmed by oath or affirmation, typically used as evidence; a mortgage is a type of loan specifically for purchasing property, and a receipt serves as proof of payment but does not pertain to the enforcement of a court's decision. Thus, execution is the appropriate mechanism for enforcing a judgment.
