Definition
"Sure of" does not appear to have an independent legal definition. The entry in Rapalje & Lawrence that was retrieved under this heading is not a definition of "sure of" but rather a fragment of an alphabetically adjacent passage concerning statutory interpretation of terms beginning with "PER-" — specifically, entries for "PERSON," "PERSON OCCUPYING," "PERSON OR PERSONS," and related phrases. No substantive legal meaning for "sure of" as a term of art appears in the available source material.
Why It Matters in Research
Researchers encountering this entry should treat it as a retrieval artifact rather than a defined legal term. The source material returned under "SURE OF" reflects a misalignment between the query term and the dictionary content — likely the result of index proximity, OCR error in digitization, or a cross-reference that did not resolve correctly in the corpus.
If you are searching for "sure of" as it appears in a historical legal instrument, deed, or statute, the phrase is most likely functioning as ordinary English — expressing certainty or guaranty — rather than as a term of art with specialized legal content. In that context, consult entries for SURETY, GUARANTY, or WARRANTY, which carry the doctrinal weight that "sure of" may be approximating in informal or archaic usage.
If your research involves the statutory interpretation entries that the source material actually contains — particularly the construction of "person," "person or persons," and related terms in nineteenth-century New York, Vermont, Rhode Island, and English practice — those topics are properly indexed under PERSON (statutory construction) and CORPORATION (as person).
Historical Dictionary Support
Rapalje & Lawrence does not define "sure of" as a legal term. The retrieved passage is a series of cross-references and case citations for statutory construction of "person" and its variants. The entry points to Wilberforce on Statute Law for the proposition that "person or persons" may include corporations, and to New York, Rhode Island, Vermont, and English Common Pleas authorities for related questions of statutory scope. None of this material bears on "sure of" as a legal phrase.
