Definition
Joint debtors are two or more persons who are united in a single, shared obligation to repay the same debt. The liability is joint in character: each debtor is bound to the whole debt together with the others, not merely to a proportionate share. To sustain an action against joint debtors, a joint and subsisting indebtedness must be established — meaning the shared obligation must still exist and must not have been extinguished, released, or merged into a judgment.
The concept is closely tied to the doctrine of merger: at common law, obtaining a judgment against one or more joint debtors merged the debt into that judgment as to all, which had the effect of discharging the remaining debtors from the original obligation even if they were never served or brought before the court. This harsh result drove the development of joint debtor statutes (see below).

Common Confusion
JOINT DEBTORS vs. JOINT AND SEVERAL DEBTORS: These are not interchangeable. Pure joint debtors share a single, undivided obligation — the creditor must sue all of them together at common law, and a judgment against one could extinguish the claim against the others. Joint and several debtors, by contrast, are each independently liable for the whole debt, allowing the creditor to pursue any one of them individually without joining the rest. Modern statutes and contract drafting have largely displaced pure joint liability in favor of joint and several liability, which means historical sources treating joint debtors carry procedural rules that may no longer apply.

Why It Matters in Research
The practical importance of this term in historical legal sources is largely procedural. At common law, the requirement to join all joint debtors in a single action created significant litigation problems when one debtor could not be served or was beyond the court's jurisdiction. The response was the enactment of joint debtor statutes in many American jurisdictions during the nineteenth century. These statutes authorized courts to render judgment against the served defendants while allowing the action to continue against those not yet reached by process — a significant departure from common law practice.
Researchers working in pre-twentieth-century materials must therefore pay close attention to whether a source predates or postdates any applicable joint debtor statute in a given jurisdiction, because the procedural rules differ sharply. Black's Law Dictionary preserves both layers — the core definition and a description of the statutory regime — reflecting this transition period.
The merger doctrine is a second trap. Bouvier's states plainly that proceeding to judgment against one or more joint debtors merges the debt as to all. Researchers encountering creditor claims against remaining debtors after judgment must check whether this doctrine was abrogated by statute in the relevant jurisdiction and era. Many jurisdictions eventually modified or abolished it, but the timing varies.
This term also connects to partnership law: partners in a general partnership are classic joint debtors for partnership obligations, which is why joint debtor doctrine appears frequently in partnership litigation in historical sources. Modern partnership statutes have largely reconstituted partner liability as joint and several, but older cases may turn on pure joint liability rules.

Historical Dictionary Support
The three shelf sources agree on the core definition — persons united in a joint liability or indebtedness — with Bouvier's offering the most substantive treatment. Bouvier's adds two critical doctrinal points: first, that a joint and subsisting indebtedness must be shown to sustain the action; and second, the merger rule that judgment against one merges the debt as to all. Both points are anchored to the same New York case, 18 Johns. 459, which Rapalje & Lawrence also cites for the definition itself.
Black's contributes the statutory dimension that the others omit or understate, describing joint debtor statutes as a recognized legislative response to the jurisdictional problem of absent or unserved co-debtors. This is a meaningful addition: it signals to researchers that the common law framework was not stable across the nineteenth century but was actively modified by legislation.
None of the historical dictionaries address what the term means in the context of modern bankruptcy or restructuring, where co-obligors and co-debtors arise in different procedural contexts governed by federal law. Researchers working with contemporary insolvency materials should not rely on these historical definitions for guidance in that setting.

Jurisdictional Note
Virtually every American jurisdiction enacted some form of joint debtor statute during the nineteenth century, but the specific rules — particularly regarding what happens to unserved defendants after judgment against the served ones — varied considerably. Researchers should identify whether the applicable jurisdiction had such a statute and, if so, its precise terms before relying on common law joint debtor doctrine from case law of the same period.
