Definition
The upset price is the minimum price at which property offered at a public auction or judicial sale may be sold. It operates as a floor: bidding opens at or above this figure, and the property cannot be knocked down to any bidder who offers less. The upset price is set before the sale begins — either by the court in a judicial proceeding, by a creditor or trustee in a forced sale, or by the seller in a voluntary auction — and it functions as a condition of sale rather than merely an opening bid.
In judicial sales, particularly mortgage foreclosure proceedings, the upset price carries additional legal weight. A court entering a final foreclosure decree may fix an upset price that accounts for the full range of encumbrances and court-ordered obligations: costs, receiver's certificates and accrued interest, prior liens, amounts diverted from property earnings, and contingent or undetermined claims. The sale cannot close for less than this figure, protecting both the integrity of the proceedings and the priority of encumbrances already recognized by the court.

Common Language
Wiktionary: "The lowest price at which an auction item may be sold."
Webster's 1913: Not separately defined; "upset" in the sense of overturning or disturbing was the primary entry.
The ordinary modern understanding — a simple price floor in any auction — is essentially correct but incomplete in the legal context. The meaningful gap is one of mechanism and consequence: in common usage, an upset price is just a reserve. In law, particularly in equity and foreclosure practice, it is a judicially or contractually imposed condition that can render a sale void or subject to challenge if not satisfied, and its calculation in a judicial sale must be sufficient to cover a specific, structured set of obligations. A researcher treating the term as merely synonymous with "reserve price" will miss that legal dimension.

Common Confusion
Upset price vs. reserve price: These terms overlap in ordinary auction usage, and historical sources sometimes treat them interchangeably. The distinction that matters for legal research is that a reserve price in a voluntary auction is typically a private, discretionary floor set by the seller, who retains the right to withdraw the property if bidding falls short. An upset price in a judicial or forced sale is a public, court-imposed or statutorily governed minimum that may be required by law and whose adequacy can be contested by parties to the proceeding. A foreclosure sale upset price is not merely a seller's preference — it is an element of the decree itself.
Upset price vs. appraised value: Some older statutes tied upset prices in judicial sales to a percentage of appraised value. These are related but distinct concepts; the upset price is the operative floor for the sale, the appraised value is an underlying valuation used (sometimes) to derive it.

Why It Matters in Research
**Judicial sale context dominates the legal record.** The term appears most heavily in equity foreclosure practice, railroad receivership cases, and judicial partition sales of the late nineteenth and early twentieth centuries. Researchers working in that period will encounter upset price as a term of art embedded in court decrees; understanding its function as a condition of sale — not just a starting bid — is essential to reading those documents accurately.
**Corpus frequency shifts over time.** The term appears with notable frequency in late 19th and early 20th century American equity decisions and treatises. It becomes less common in primary legal sources as non-judicial foreclosure procedures expanded and statutory minimum-bid rules replaced court-set upset prices in many jurisdictions. Researchers in modern sources may find "minimum bid," "floor price," or "reserve" used where historical sources said "upset price."
**Foreclosure decree structure.** Bouvier's entry is particularly useful here: it flags that in a final foreclosure decree, the upset price must be large enough to cover not just the principal debt but costs, allowances, receiver's certificates and interest, prior liens, diverted earnings, and undetermined claims. A researcher analyzing a historical foreclosure decree who does not understand this structural requirement may misread why a particular upset price was set where it was, or why a sale was subsequently challenged as inadequate.
**Jurisdictional variation in judicial sales.** Some states required upset prices by statute or equity rule in judicial sales; others did not. The presence or absence of an upset price in a historical sale record can itself be informative about the governing jurisdiction's practice.
**Auction law generally.** In non-judicial auction contexts — voluntary sales of goods or real property — the upset price functions analogously to a reserve. UCC Article 2 and common law auction rules govern whether a sale is "with reserve" or "without reserve," and the upset price concept maps onto "with reserve" auction structure. Researchers crossing between equity-court records and commercial auction contexts should track which regime applies.

Historical Dictionary Support
Black's Law Dictionary (both the first and second editions) offers an identical, spare definition drawn from Wharton: the upset price is the amount at which property is put up at auction, with the first bidder at that price declared the buyer. This framing emphasizes the mechanics — the opening of bidding — but does not capture the judicial-sale dimension or the protective function of ensuring encumbrance coverage.
Bouvier's entry is substantially more useful for legal researchers. It correctly identifies the upset price as a floor below which the property cannot be sold, and then — critically — provides the specific accounting logic that courts applied in foreclosure decrees. Bouvier's incomplete sentence at the end of the entry (likely a typographic truncation in the source) suggests the original text continued to enumerate additional categories of claims that must be absorbed into the upset price calculation.
Neither Black's edition captures the distinction between a judicially mandated upset price and a voluntary auction reserve, nor do they address what happens when a sale is conducted below the upset price. Researchers relying solely on Black's will have a functional but shallow understanding of the term's operation in equity practice.
No significant divergence between Black's first and second editions; the definition was carried forward unchanged.

Jurisdictional Note
American equity courts in the 19th century developed upset price doctrine primarily through mortgage foreclosure and railroad receivership practice. Some states codified upset price requirements in their judicial sale statutes; others left the matter to court discretion. Modern foreclosure statutes in most U.S. jurisdictions have replaced or substantially modified this framework, making the term more historically significant than operationally current in most states.
