Definition
A payment made by a debtor who owes multiple debts to a single creditor, where the debtor fails to designate which debt the payment is intended to satisfy. Because no specification accompanies the payment, the creditor retains the right to apply the funds to whichever obligation the creditor chooses. The doctrine governs the practical question of appropriation — that is, who controls the allocation of an undesignated payment, and under what constraints.
Common Confusion
INDEFINITE PAYMENT vs. APPROPRIATION OF PAYMENTS. These two concepts are intertwined but distinct. Indefinite payment describes the situation — a payment made without specification. Appropriation of payments describes the legal consequence — the rules determining how that undesignated payment gets allocated. Researchers encountering "indefinite payment" in historical sources should immediately look to appropriation rules to understand the operative legal effect. Some historical dictionaries treat the terms as nearly synonymous, which can obscure this functional distinction.
Why It Matters in Research
The primary research trap is jurisdictional framing. The doctrine appears in historical legal dictionaries with an explicit "Scotch law" label — both Black's and Burrill flag it as originating in Scottish legal tradition through Bell's Dictionary. Researchers working in English or American sources should not assume the Scottish framing maps cleanly onto common law appropriation doctrine, which developed its own rules for creditor and debtor elections, often through equity.
In American and English common law sources, this concept most frequently surfaces under the heading of "appropriation of payments" rather than "indefinite payment" as a standalone term. A researcher who searches only for "indefinite payment" in historical American reporters or treatises may find thin results; the substantive doctrine appears under different vocabulary. Rapalje & Lawrence makes this connection explicit, cross-referencing "APPROPRIATE, § 5" — a useful navigational signal that the operative treatment lives elsewhere in the corpus.
The creditor's right to apply an unspecified payment is not unlimited in most common law jurisdictions. Equitable constraints developed over time — for example, restrictions on applying a payment to a time-barred or unenforceable debt over the debtor's objection. These nuances do not appear in the bare dictionary definitions but are critical in contract and debt litigation research.
For researchers working with 19th-century commercial records, this doctrine arises frequently in creditor-debtor disputes involving running accounts, multiple loans, or compound obligations — contexts where a debtor might strategically omit a designation to avoid applying payment to the most burdensome debt, or a creditor might apply payment to the oldest or least secured obligation.
Historical Dictionary Support
The four source dictionaries are in close agreement on the core definition, differing mainly in framing and completeness. Black's and Burrill share nearly identical text, both attributing the doctrine explicitly to Scotch law and citing Bell's Dictionary as authority — a reliable signal that this entry derives from a common Scottish legal source rather than independent English or American development.
Bouvier adds a useful practical dimension absent from the other entries: the affirmative statement that in cases of indefinite payment, "the creditor has a right to make such appropriation." This is the operative legal consequence the other definitions imply but do not state directly. Bouvier's phrasing is the most actionable for a researcher trying to understand what the doctrine does.
Rapalje & Lawrence offers the shortest treatment but the most useful cross-reference, pointing researchers toward "APPROPRIATE, § 5" — indicating that the compilers understood indefinite payment as a sub-issue within the larger appropriation-of-payments framework rather than a freestanding doctrine.
What the historical dictionaries collectively miss: they do not address the debtor's right to designate at or before the time of payment, nor the timing rules governing when the creditor's election must be made. These procedural dimensions are essential to how the doctrine operates in litigation but require consultation of treatises and case law rather than dictionary entries.
Jurisdictional Note
The term carries an explicit Scottish law pedigree in primary historical sources. In English and American common law, the equivalent doctrine travels under "appropriation of payments" and is governed by a mix of common law election rules and, in some jurisdictions, statutory frameworks. Researchers should verify whether their target jurisdiction follows debtor-first election rules, creditor-first election rules, or a pro-rata default.
