Definition
A debt by specialty is a debt that is evidenced by, or acknowledged through, a sealed instrument — that is, a formal written document executed under seal, such as a bond, obligation, deed of covenant, deed of sale, or a lease that expressly reserves a rent obligation. The seal distinguishes this class of debt from a simple contract debt (debt in simple contract), which arises from informal agreements, written or oral, that carry no seal.
The practical significance of the distinction historically was substantial: debts by specialty occupied a higher rank in the hierarchy of debts, particularly in the administration of a decedent's estate, and were subject to longer statutes of limitation than simple contract debts.

Common Confusion
DEBT BY SPECIALTY vs. SIMPLE CONTRACT DEBT. The core distinction is formal, not substantive. Two parties can owe each other the same sum for the same underlying obligation, but whether that obligation is memorialized in a sealed instrument determines its legal classification and, historically, its priority and enforceability timeline. A promissory note without a seal is a simple contract debt; the same obligation reduced to a bond under seal becomes a specialty debt. Researchers working in older materials should not assume that "specialty" signals anything about the nature or subject matter of the underlying obligation — it signals only the form of the instrument.
DEBT BY SPECIALTY vs. SPECIALTY (the instrument). The specialty is the document; the debt by specialty is the obligation that document evidences. The two terms are closely related but are not interchangeable. See SPECIALTY.

Why It Matters in Research
This term is primarily a historical category. Modern sealed-instrument doctrine has eroded significantly across most U.S. jurisdictions, and the formal distinction between sealed and unsealed instruments — once a cornerstone of common law pleading and debt hierarchy — has been abolished or substantially curtailed by statute in most states. Researchers encountering this term in contemporary materials should treat it as a signal that the source is either historical or is deliberately invoking older doctrinal frameworks.
Several research traps to watch for:
First, priority in estate administration. Pre-20th century sources on decedents' estates will rank debts by specialty above simple contract debts in the order of payment from estate assets. This hierarchy appears in equity treatises, early probate statutes, and chancery decisions. Researchers navigating older estate administration materials must understand this classification to interpret creditor priority disputes correctly.
Second, statute of limitations. At common law and in early American statutes, debts by specialty carried longer limitation periods than simple contract debts — often 20 years versus 6. Modern limitation statutes have largely collapsed this distinction, but historical litigation turning on the applicable limitations period may hinge entirely on whether the underlying instrument qualified as a specialty.
Third, pleading in debt. The common law action of debt was sensitive to the form of the underlying obligation. Debt on a specialty was a distinct form of the action from debt on a simple contract. Early American court records and reported decisions that describe a cause of action as "debt on specialty" are situating themselves within this framework.
Fourth, the seal itself. What constitutes a valid seal has varied enormously by jurisdiction and era — from wax impressions to paper wafers to printed circles with "L.S." (locus sigilli) to mere recitals that a document "is sealed." Researchers should not assume that a document is or is not a specialty without examining the jurisdiction's rules on seal formalities at the relevant time.

Historical Dictionary Support
Black's Law Dictionary defines the term concisely as a debt "due, or acknowledged to be due, by some deed or instrument under seal," citing Blackstone's Commentaries at 2 Bl. Comm. 465. This is the canonical source for the term's common law meaning and reflects the English tradition that American law largely inherited.
Blackstone's framing is instructive in its examples — deed of covenant, deed of sale, lease reserving rent, bond or obligation — because it confirms that the category is defined by form, not by the type of commercial transaction. A lease is not intuitively a "specialty," but if it reserves rent under seal, the rent obligation qualifies.
Black's entry is brief and does not address the erosion of the doctrine in American jurisdictions, the variation in seal requirements across states, or the legislative abolition of the distinction in many modern codes. For those dimensions, researchers must look beyond the dictionary to state-specific statutes and treatises on common law pleading.

Jurisdictional Note
The distinction between specialty and simple contract debts has been substantially or entirely abolished in most U.S. jurisdictions by statute, and many states have eliminated the legal effect of seals on private instruments altogether. A small number of states retain some formal recognition of sealed instruments, but even where seals are recognized, the old priority hierarchy in estate administration has generally been replaced by uniform creditor-priority schemes. Researchers should verify the applicable jurisdiction's current seal statute before treating this classification as operative.
