Definition
A Latin term meaning "I have confirmed." In medieval conveyancing practice, *confirmavi* was the operative word — the formal verbal act — appearing in deeds of confirmation, by which a grantor ratified, strengthened, or made valid a prior grant or conveyance. Its function was performative: the word itself accomplished the legal act of confirmation when uttered or written in the prescribed form. Like *dedi* ("I have given") in a deed of grant or *concessi* ("I have granted") in a deed of concession, *confirmavi* carried precise operative weight in the technical vocabulary of ancient English land transfer documents.
Common Confusion
CONFIRMAVI should not be confused with the broader concept of confirmation as a general legal act. The term is specifically the first-person Latin operative word appearing in the body of a formal deed — not a description of confirmation as a doctrine, not a synonym for ratification in modern contract law, and not interchangeable with terms like *confirmo* (present tense) or *confirmatio* (the noun form denoting the deed or instrument itself). Researchers encountering *confirmavi* in a historical document are looking at the verb of execution, not a heading or doctrinal label.
Why It Matters in Research
This term is primarily encountered in transcriptions of medieval and early modern English land records, particularly deeds of confirmation recorded in plea rolls, cartularies, and early common law sources. Researchers working in the Law Mind corpus should note several practical points.
First, *confirmavi* appears almost exclusively in primary source materials predating systematic law reporting. It surfaces in treatise discussions of conveyancing forms — notably Fleta — rather than in case law. Researchers tracing the forms of ancient deeds will encounter it alongside *dedi*, *concessi*, *donavi*, and *vendidi* as part of a recognized vocabulary of operative words, each carrying distinct doctrinal significance about what interest was being transferred or confirmed.
Second, the word's significance is formal rather than substantive: its presence in a deed signals the document's nature and legal function. When reading historical treatises or digests that discuss the requirements for a valid deed of confirmation, *confirmavi* marks the moment of legal execution in the instrument's operative clause. Misreading or overlooking this word can cause a researcher to misclassify a document — confusing a deed of confirmation with an original grant, for example.
Third, because this is a pure Latin term of art from medieval conveyancing, it does not carry forward meaningfully into modern property law vocabulary. Researchers should not expect to find it in 19th-century American legal materials except in historical or comparative discussions of English land law.
Historical Dictionary Support
The three source dictionaries are in close agreement, all defining *confirmavi* identically as "I have confirmed" and identifying it as the emphatic operative word in ancient deeds of confirmation, with each citing Fleta, lib. 3, c. 14, § 5 as the authoritative source. There is no substantive divergence among them.
Burrill's entry contains a minor textual anomaly — an apparent transcription artifact that introduces a fragment concerning *confiscate* and Roman law into the middle of the *confirmavi* entry. This is an editorial error in the source text, not a point of legal substance, and should be disregarded.
What the historical dictionaries do not address is the broader conveyancing context that gives *confirmavi* meaning: the taxonomy of operative words in medieval English deeds and the formal requirements for deeds of confirmation as discussed in Fleta and Littleton's *Tenures*. Researchers seeking that context will need to go beyond dictionary sources to the treatise literature directly.
