Filing an appeal does not by itself prevent the winner from enforcing the judgment. A stay must be obtained, and for money judgments that ordinarily requires security.

The bond. A supersedeas bond typically covers the judgment, anticipated interest during the appeal, and costs — often set above one hundred percent of the judgment. On entry, enforcement is stayed as of right in most systems.

Alternatives to a full bond. Courts may accept a letter of credit, a cash deposit, a lien on identified property, or a reduced bond where the appellant shows the full amount would be ruinous and the appellee’s position is otherwise protected. Some states cap bonds by statute.

Non-money judgments. Injunctions and declaratory relief are stayed on a discretionary standard: likelihood of success, irreparable harm, harm to the other side, and the public interest. The motion goes first to the trial court, then to the appellate court.

Timing. Move immediately. A judgment creditor that garnishes accounts on day one has changed the negotiating landscape before the bond application is heard.

Cost. Bond premiums run to a percentage of the penal sum annually and usually require collateral. That expense belongs in the appeal decision, not after it.
