Surety and Undertaking on Appeal

When a party loses a case in a New York trial court and decides to appeal, the judgment does not automatically disappear while the appeal is pending. In many situations, the prevailing party may begin enforcing the judgment immediately. To prevent enforcement during an appeal, the appealing party often must post a surety or undertaking—a financial guarantee that protects the judgment creditor in the event the appeal is unsuccessful. Understanding how undertakings and surety bonds function under New York law is essential for any party considering an appeal of a money judgment.

Our firm represents clients throughout New York in appellate matters, including securing stays of enforcement, posting undertakings, and resolving disputes over the sufficiency of surety. This page explains the core concepts, statutory requirements, and practical considerations involved in posting a surety or undertaking on appeal.

What Is an Undertaking on Appeal?

An undertaking is a written promise, typically backed by a surety company or cash deposit, that guarantees payment of a judgment if the appellate court affirms the lower court's decision. In effect, it assures the party who won at trial that they will recover what they are owed, even if the appealing party delays enforcement by pursuing an appeal.

The undertaking serves two competing interests. It allows the appealing party (the appellant) to challenge the judgment without facing immediate and potentially irreversible enforcement, such as the seizure of assets or garnishment of accounts. At the same time, it protects the prevailing party (the respondent) from the risk that the appellant will dissipate assets or become insolvent during the appeal.

The Automatic Stay Under CPLR 5519

New York's Civil Practice Law and Rules (CPLR) govern stays of enforcement during an appeal. Under CPLR 5519(a), service of a notice of appeal or an affidavit of intention to move for permission to appeal automatically stays enforcement of a judgment in certain circumstances—provided the appellant satisfies specific conditions, including posting an undertaking.

For example, when an appeal is taken from a judgment directing the payment of a sum of money, the automatic stay takes effect if the appellant gives an undertaking that the judgment will be paid if it is affirmed or the appeal is dismissed. The amount of the undertaking generally must cover the full sum the judgment directs to be paid.

Other subsections of CPLR 5519 address different types of judgments and orders, such as judgments directing the assignment or delivery of personal property, judgments directing the execution of a conveyance, and judgments affecting interests in real property. Each scenario carries distinct undertaking requirements, and the appellant must comply precisely to obtain the protection of the automatic stay.

Discretionary Stays

Where an appellant cannot secure an automatic stay—or where the type of judgment does not qualify—the court retains discretion under CPLR 5519(c) to grant a stay upon such terms as it deems appropriate. In exercising this discretion, the court may require an undertaking, set a specific amount, or impose other conditions designed to protect the respondent. A motion for a discretionary stay allows the court to balance the equities and tailor relief to the particular circumstances of the case.

The Role of the Surety

A surety is the entity that backs the undertaking and promises to pay if the appellant fails to satisfy the judgment after an unsuccessful appeal. In most cases, the surety is a corporate surety company authorized to do business in New York and approved by the Superintendent of Financial Services. Corporate sureties charge a premium—typically a percentage of the bond amount—and may require collateral or a review of the appellant's financial condition before issuing the bond.

Under CPLR 2502, an undertaking may also be given by depositing the required sum with the court or, in some cases, by personal sureties. However, personal sureties must meet qualification requirements, and the respondent has the right to challenge their sufficiency. For most appellants, a corporate surety bond is the most efficient and reliable option.

Requirements for a Valid Undertaking

New York law sets out several formal requirements that govern undertakings. Among the most important:

• Proper amount: The undertaking must be in an amount sufficient to satisfy the judgment, including any costs and interest as required by the governing CPLR provision.
• Qualified surety: The surety must be authorized and approved to issue undertakings in New York.
• Proper form and execution: The undertaking must be in writing, properly executed, and contain the statutory promises required for the type of judgment at issue.
• Service and filing: The appellant must serve the undertaking on the respondent and file it as required so that the respondent can evaluate and, if necessary, challenge it.

Challenging the Sufficiency of an Undertaking

The respondent is not obligated to accept an undertaking at face value. CPLR 2506 and related provisions permit a party to except to the sufficiency of a surety. If an exception is filed, the surety may be required to justify—that is, to demonstrate that it is financially capable of satisfying the obligation. If a personal surety fails to justify, or if the undertaking is otherwise defective, the stay may be vacated, and the respondent may resume enforcement of the judgment.

For this reason, appellants should ensure that their undertaking is properly drafted and backed by a qualified surety from the outset. A defective undertaking can leave an appellant exposed to immediate enforcement despite the pendency of an appeal.

Practical Considerations for Appellants

Posting an undertaking on appeal involves more than simply contacting a surety company. Appellants should consider the following:

• Cost of the bond: Surety premiums and collateral requirements can be significant, particularly for large money judgments. Appellants should weigh these costs against the potential benefit of staying enforcement.
• Timing: The automatic stay generally requires that the undertaking be in place when the notice of appeal is served. Delay can result in the loss of the stay and exposure to enforcement.
• Accuracy of the amount: Underestimating the required amount may render the undertaking insufficient, while overestimating increases costs unnecessarily.
• Alternatives: Where a corporate surety bond is impractical, an appellant may consider depositing funds with the court or moving for a discretionary stay on alternative terms.

Considerations for Respondents

If you have won a judgment and the losing party files an appeal, you have important rights. You should review any undertaking carefully to confirm that the amount is adequate, the surety is qualified, and the form complies with the CPLR. If the undertaking is deficient, you may file an exception or move to vacate the stay. Prompt action protects your ability to enforce the judgment without unnecessary delay.

The rules governing sureties and undertakings on appeal are technical and unforgiving. A misstep can mean the loss of a stay or the inability to collect on a hard-won judgment.
