Definition
A periodic payment made by copyhold tenants in certain parts of England to their new lord upon the death of the preceding lord. The payment functioned as a formal recognition of the incoming lord's authority — an act of fealty expressed in money rather than ceremony. It was not rent, nor a penalty, nor a purchase price; it was a ritual acknowledgment that the tenant held land at the lord's sufferance and that the death of one lord transferred that relationship, not terminated it.
Acknowledgment money belongs to the vocabulary of English copyhold tenure, the system by which customary tenants held land of a manor "by copy of court roll" — meaning that their title derived from an entry in the manorial court records rather than from a formal deed. Copyhold was a creature of English manorial law and had no direct American equivalent. It was abolished in England by the Law of Property Act 1922.
Common Confusion
Do not confuse acknowledgment money with: (1) the modern notarial acknowledgment attached to deeds and instruments under recording act requirements — an entirely different legal concept sharing only the word "acknowledgment"; (2) rent or fee farm rent, which were ongoing periodic payments; or (3) relief or heriot, other feudal incidents also triggered by a change in lordship or tenancy but differing in form, timing, and legal character. Acknowledgment money was specific to the copyhold context and to the moment of succession to lordship.
Why It Matters in Research
This term appears almost exclusively in historical English sources. Researchers encountering it should treat it as a signal that the surrounding text concerns English manorial or copyhold law — not modern landlord-tenant law, not American property law, and not the modern law of acknowledgments (the notarial act of a grantor confirming a signature before a public officer). The word "acknowledgment" is doing entirely different work here than in any modern American legal context.
The primary research trap is conflation with modern acknowledgment doctrine. In contemporary property practice, an "acknowledgment" is the notarial certification attached to deeds, mortgages, and other instruments. Acknowledgment money has nothing to do with this usage. A researcher finding "acknowledgment money" in a digitized historical text and searching forward or backward for related doctrine may inadvertently land in recording act doctrine — a category error.
The term also connects genealogically to laudemium, a cognate concept from Roman and civil law traditions, noted explicitly in Burrill. Researchers tracing the concept into Continental legal history should use laudemium as the search term in civil law sources; acknowledgment money is the English customary law label for the same underlying obligation.
For researchers working on English manorial records, estate histories, or early Anglo-American property law, this term may appear in court rolls, manorial surveys, and conveyancing treatises from roughly the sixteenth through nineteenth centuries. It is largely absent from American primary sources because copyhold tenure was not transplanted to the colonies in functional form.
Historical Dictionary Support
Black's Law Dictionary and Burrill's Law Dictionary are in close agreement on substance. Both define acknowledgment money as a sum paid by copyhold tenants upon the death of their lord, functioning as recognition of the new lord's authority. Both cite Cowell's legal dictionary (The Interpreter, first published 1607) as the primary authority — meaning neither Black nor Burrill was drawing on independent case law or statute, but rather on a shared antiquarian lexicographic source. Blount (Nomo-Lexikon, 1670) and Holthouse appear additionally in Burrill's entry.
Burrill adds the explicit cross-reference to laudemium, which is the more useful pointer for researchers needing doctrinal depth. The Latin term connects acknowledgment money to a broader tradition of recognition payments in feudal and quasi-feudal land systems — payments owed on succession of either lord or tenant — and opens access to civilian and comparative sources that the English-only labels do not.
Neither Black nor Burrill discusses statutory abolition, which is unsurprising given the editions in which these definitions appeared; the formal abolition of copyhold came later. Modern editions of Black's have substantially compressed or removed this entry, reflecting the term's obsolescence.
