Definition
Extinguishment of debt is the termination of a debt obligation by operation of law or by an act of the parties, such that the debt ceases to exist entirely and can no longer be enforced. Extinguishment is distinguished from mere suspension or discharge in that the underlying obligation is permanently destroyed rather than postponed or excused.
Extinguishment may occur through several recognized mechanisms:
(1) Merger. When a debt is reduced to judgment, the original obligation merges into the judgment and the pre-existing debt is extinguished. The creditor's right of action thereafter runs on the judgment, not on the original claim.
(2) Confusion of debtor and creditor. When the same person becomes both obligor and obligee — for example, when a creditor dies and the debtor is named sole executor of the creditor's estate — the debt is extinguished because a person cannot owe a legal obligation to themselves.
(3) Payment and satisfaction. Full payment of the amount due extinguishes the debt. An accord and satisfaction, where the parties agree to substitute a different performance for the original obligation, achieves the same result.
(4) Release. A creditor may extinguish a debt by formally releasing the debtor, typically in writing and, under older common law, under seal.
(5) Novation. When the parties agree to substitute a new obligation for an old one — whether by replacing a party, changing the subject matter, or altering essential terms — the original debt is extinguished and replaced by the new agreement.
(6) Bankruptcy discharge. A discharge in bankruptcy extinguishes the personal liability of the debtor, though it does not always destroy the underlying debt as an in rem obligation against secured property.

Common Confusion
Extinguishment is sometimes used interchangeably with discharge, but the terms are not identical. Discharge, particularly in bankruptcy, relieves the debtor of personal liability but does not always destroy the creditor's ability to enforce a lien against property. Extinguishment implies total destruction of the obligation. Similarly, extinguishment should not be confused with statute of limitations bar: a time-barred debt is not extinguished — the underlying obligation survives even though enforcement is blocked.

Why It Matters in Research
Researchers working with historical sources will encounter extinguishment in several distinct doctrinal contexts that are not always clearly separated in older materials. The confusion-of-interests doctrine — covering scenarios like the debtor-executor problem or marriage between creditor and debtor — appears frequently in English common law reporters and early American equity cases. These rules have largely been modified by statute, particularly in the executor context: most modern jurisdictions hold that naming a debtor as executor no longer automatically extinguishes the debt, reversing the common law result. Research into pre-20th century sources should treat these rules as presumptively abrogated unless a specific jurisdiction can be shown to have preserved them.
The merger-into-judgment rule remains practically significant and is still followed broadly, though its consequences vary: some jurisdictions allow revival of the original claim in narrow circumstances. Researchers examining pre-judgment negotiation, settlement, or enforcement strategy will need to account for which obligation — the original contract debt or the judgment — is controlling at any given moment.
In the family law context, the historical rule that marriage between a feme sole creditor and her debtor extinguished the debt reflects coverture doctrine and is entirely obsolete. Modern marital debt allocation operates on entirely different principles. Researchers should treat Burrill's treatment of this point as historical background only.
For debt securities and corporate finance research, extinguishment has a distinct technical meaning in accounting and securities regulation contexts — specifically, when an issuer repurchases or retires bonds before maturity. That usage is largely outside classical common law doctrine but intersects with corporate law research on balance sheet treatment and gain-on-extinguishment recognition.

Historical Dictionary Support
Burrill's Law Dictionary captures the classical common law understanding concisely, identifying the three paradigm cases: merger by judgment, the debtor-executor scenario, and coverture-based confusion of obligation. The references to Coke (8 Co. 136), Plowden (Plowd. 184), and Salkeld (1 Salk. 304) situate the doctrine firmly in English common law. Burrill does not discuss payment, novation, or release as mechanisms of extinguishment, likely because those topics were treated under separate headings in legal dictionaries of the period.
What Burrill omits is as significant as what he includes: he offers no treatment of equitable doctrines that softened extinguishment in hardship cases, no acknowledgment of emerging statutory modifications, and no discussion of partial extinguishment (as in compromise or accord). Wharton, referenced by Burrill, follows the same taxonomy. Researchers relying solely on these sources will miss the substantial body of equity court decisions that carved exceptions into the strict common law rules, particularly in the debtor-executor context where courts of equity often found ways to preserve the estate's claim on behalf of other beneficiaries.

Jurisdictional Note
Modern treatment of the debtor-executor scenario varies by jurisdiction. Many states have enacted statutes expressly providing that the appointment of a debtor as executor does not extinguish the debt, protecting the interests of other estate beneficiaries. The marriage-extinguishes-debt rule is universally abrogated by the elimination of coverture. Researchers should verify current statutory law before assuming any common law extinguishment rule remains operative.
