Definition
A new promise is a subsequent undertaking by a promisor that recognizes and agrees to fulfill an earlier obligation that has become legally unenforceable. The new promise does not create an entirely separate contractual relationship from scratch; rather, it revives or renews the original duty, giving it fresh legal life. The original promise supplies the consideration — no independent consideration for the new promise is required, because the moral obligation arising from the original debt or duty is treated as sufficient to support the new undertaking.
New promises arise most commonly in two contexts:
(1) Statute of Limitations. When a debt or cause of action has been extinguished — or is about to be extinguished — by the running of the limitations period, a debtor who acknowledges the debt and promises to pay it makes a new promise that restarts the limitations clock. The new promise need not be in any particular form, but it must be clear, direct, and unequivocal; a vague acknowledgment may not suffice.
(2) Discharge in Bankruptcy. A debtor whose obligation has been discharged in bankruptcy may voluntarily make a new promise to pay that debt. Historically, such a promise was enforceable at common law; modern federal bankruptcy law imposes significant formal requirements — including court approval and specific timing rules — for reaffirmation agreements that function as new promises in this context.

Common Confusion
New promise is frequently conflated with acknowledgment of debt. The distinction matters: an acknowledgment is a statement recognizing that a debt exists, while a new promise is an express commitment to pay it. Some jurisdictions treat an unqualified acknowledgment as implying a new promise; others require the promise to pay to be explicit. Researchers working in historical sources will encounter both usages and must read carefully to determine which the court or treatise writer actually meant. Similarly, new promise should not be confused with novation, which substitutes an entirely new obligation and discharges the old one; a new promise revives, rather than replaces, the original duty.

Why It Matters in Research
The doctrine of new promise sits at the intersection of contracts, limitations law, and bankruptcy, and its treatment has shifted considerably across time and jurisdiction.
Statute of limitations research is the primary context where this term appears. Historical cases and treatises — particularly nineteenth-century English and American sources — devote substantial attention to what language constitutes a sufficient new promise to toll or restart the limitations period. Researchers must be alert to the fact that courts in this era were sharply divided: some required an express promise to pay; others held that a mere written acknowledgment was enough; still others distinguished between partial payments (which might imply a new promise) and bare admissions. Black's Law Dictionary's emphasis on "recognizes and revives" captures the consensus formulation, but the precise standard varied by state.
Bankruptcy context requires special caution. The enforceability of new promises after discharge changed dramatically with the enactment of the Bankruptcy Reform Act of 1978 and its successors. Pre-1978 authorities, and many historical dictionary entries, reflect a common-law world in which post-discharge promises were routinely enforceable without formality. That rule no longer applies under federal bankruptcy law. Researchers relying on older treatises or cases for this proposition must verify whether the modern reaffirmation agreement regime has displaced the common-law rule in their jurisdiction.
Statute of Frauds overlap is flagged by Bouvier, who notes that the renewal of a promise to pay can constitute a new promise within the meaning of the Statute of Frauds. This means that in some historical and modern contexts, a new promise must be in writing to be enforceable. This is an easy trap to miss when reading cases that seem to enforce oral new promises — check whether a writing requirement applied in that jurisdiction at that time.
Corpus navigation tip: In Law Mind sources, discussions of new promise are most likely embedded within entries on LIMITATIONS (as Bouvier explicitly cross-references), ACKNOWLEDGMENT OF DEBT, STATUTE OF FRAUDS, and DISCHARGE IN BANKRUPTCY rather than appearing as standalone doctrine.

Historical Dictionary Support
All three source dictionaries agree on the essential structure: a new promise presupposes an original promise that has been rendered invalid or unenforceable, and operates to revive the promisor's obligation to perform. The formulations of Black's, Rapalje & Lawrence, and Bouvier track each other closely, which reflects the settled nature of the core doctrine in the classical common-law period.
Black's formulation is the most analytically precise, emphasizing that the new promise "recognizes and revives" the former promise — language that captures the relational character of the doctrine and distinguishes it from a truly independent agreement.
Bouvier adds the most practical intelligence for researchers, noting the Statute of Frauds dimension and explicitly cross-referencing LIMITATIONS, signaling that new promise is best understood as a satellite concept to limitations doctrine rather than a freestanding doctrine.
Rapalje & Lawrence's entry is substantively identical to Bouvier's — the shared language suggests common sourcing — but its reference to English statutes (60 Geo. III and 1 Geo.) is a historical artifact pointing to English limitations legislation. Researchers working in English legal history may find this a useful thread; researchers focused on American law can treat it as background noise.
What the historical dictionaries do not address is the modern bankruptcy reaffirmation context, for the obvious reason that the current federal bankruptcy framework postdates these works. They also do not engage with the evidentiary question of what proof suffices to establish a new promise — a question that generated voluminous case law and is not resolved by the definitions alone.

Jurisdictional Note
American states vary meaningfully on whether an acknowledgment alone — without an explicit promise to pay — restarts the limitations period, or whether an express new promise is required. Some states have codified these rules by statute. In federal bankruptcy practice, the reaffirmation agreement requirements of the Bankruptcy Code now govern what would have been treated as common-law new promises in the discharge context, and state common-law rules on that point are largely preempted.
