Definition
An appeal bond is a surety instrument required of a party who appeals a court judgment, binding that party to pay damages, costs, and sometimes the full judgment amount if the appeal is unsuccessful or not prosecuted to completion. It serves a dual purpose: it protects the appellee against the risk that the appellant will be unable to satisfy the judgment after delaying enforcement through appeal, and it discourages frivolous appeals.
In practice, appeal bonds take several forms depending on the procedural posture and what the bond is meant to secure:
1. Cost bond: A bond covering only the costs of the appeal — filing fees, transcript costs, and similar expenses — if the appellant loses. This is the narrower, older form.
2. Supersedeas bond: A bond that suspends (supersedes) enforcement of the trial court's judgment while the appeal is pending. This is the form most litigants mean when they say "appeal bond" in modern practice, and it typically must equal or exceed the full judgment amount plus interest and costs.
The two are distinct instruments, though they are often conflated in casual usage and sometimes combined in practice.

Common Confusion
APPEAL BOND vs. SUPERSEDEAS BOND: These terms are often used interchangeably in court filings and secondary sources, but they are not identical. An appeal bond in its historical and narrower sense secures only costs if the appeal fails. A supersedeas bond does more: it stays execution of the judgment entirely during the appellate period and must be large enough to protect the appellee against the full value of what they won. In modern federal practice and most state systems, the supersedeas bond has become the dominant instrument, and the term "appeal bond" now often refers to it. Researchers reading older materials should not assume the two terms carry the same meaning across time periods.

Recognized Forms
/SUBTYPES
Cost Bond: Secures only appellate costs owed to the opposing party if the appeal fails. Typically the minimum required to perfect an appeal under older procedural codes.
Supersedeas Bond: Secures the full judgment, plus anticipated interest and costs, during the pendency of appeal. Triggers an automatic stay of execution in most jurisdictions upon proper filing.
Injunction Appeal Bond: Required when an appeal involves an injunction. Courts may require a bond to protect parties who were restrained by the injunction during the appeal period.

Why It Matters in Research
The most critical research trap is the terminological drift between appeal bond and supersedeas bond. Nineteenth and early twentieth century materials — including most of the historical dictionary sources on this shelf — define appeal bond in the narrower cost-bond sense. Modern federal and state rules have largely absorbed that narrower instrument into the supersedeas bond framework, but older cases and treatises have not changed their language. A researcher reading an 1890 opinion about an "appeal bond" requirement may be reading about a cost bond only, not about a stay of execution.
Federal Rule of Civil Procedure 62 governs the supersedeas bond in federal court, setting the standard against which many state rules are measured. Researchers should always identify whether the jurisdiction and time period in question uses appeal bond to mean only costs, the full judgment, or some hybrid.
The bond amount is a live issue in large commercial judgments. Courts have wrestled with whether requiring a bond equal to a massive judgment effectively denies the right to appeal, and several jurisdictions have enacted caps or granted discretionary waivers. Any research into appeal bonds in the context of large verdicts — antitrust damages, mass torts, punitive awards — should check whether the jurisdiction has such a cap, as many were adopted in the 1990s and 2000s in direct response to high-profile cases.
For tax and administrative appeals, the appeal bond framework operates differently or not at all. IRS administrative appeals within the agency (see IRS Appeals Office Administrative Appeals, tax_126) do not require surety bonds in the traditional sense; payment and collection mechanisms are governed by separate statutory schemes. Do not carry civil litigation bond doctrine into the tax administrative context without verifying the applicable rules.
Immigration bond hearings (immigration_82) involve detention bonds that are conceptually related — they secure a party's appearance and compliance — but operate under an entirely separate statutory and regulatory framework. The term "bond" in immigration proceedings should not be analyzed through civil appeal bond doctrine.

Historical Dictionary Support
Black's Law Dictionary states the definition concisely: the appeal bond is given on taking an appeal, binding the appellant to pay damages and costs if the appeal is not prosecuted with effect. This reflects the cost-bond conception dominant in earlier American practice, and it accurately captures the instrument as it functioned under the Field Code era and its successors.
What Black's does not capture — and what no single historical dictionary entry does well — is the procedural bifurcation between the bond required to perfect the appeal and the bond required to stay execution. Historical sources tend to treat these as one instrument or to address them in separate entries under different headings (see supersedeas). Researchers relying solely on the Black's entry will have a correct but incomplete picture of how the instrument operates in modern practice.

Jurisdictional Note
Federal courts are governed by FRCP 62 for supersedeas bonds and related appellate stays, with additional rules in the Federal Rules of Appellate Procedure. State practice varies considerably: some states have eliminated mandatory bond requirements for certain categories of appellants (government entities, indigent parties), and others have enacted statutory caps on bond amounts in large-judgment cases. The distinction between perfecting an appeal and staying execution — and whether a bond is required for one, both, or neither — is jurisdiction-specific and must be verified in each forum.
