Definition
In legal usage, "firmly" is a term of art appearing in two distinct formulaic contexts:
1. In affidavits and sworn statements: The phrase "firmly believes" denotes a strong or elevated degree of belief — more than general or casual belief, approaching certainty. Courts have treated it as equivalent to "verily believes," signaling a heightened personal conviction by the affiant.
2. In bonds and recognizances: The phrase "held and firmly bound" is the operative language by which an obligor acknowledges a binding legal obligation, functioning as an acknowledgment of indebtedness and creating the legal force of the instrument.
In both contexts, "firmly" is not mere rhetorical flourish. It is a word with legal consequence — its presence or absence can determine whether an affidavit or bond is legally sufficient.

Common Language
Modern common usage (Wiktionary): "In a firm or definite or strong manner; securely; definitively."
Historical common usage (Webster's 1913): "In a firm manner."
The gap between common and legal meaning is subtle but important. In ordinary usage, "firmly" is a modifier of degree — it intensifies whatever it modifies but carries no independent legal significance. In legal instruments, however, "firmly" is a term of art with structural function. Substituting a synonym or paraphrase may not satisfy the legal requirement; the word (or its recognized equivalent) must appear. A drafter who treats "firmly" as mere emphasis and omits it from a statutory affidavit or replaces it with "genuinely" or "strongly" may produce a legally deficient instrument.

Common Confusion
The phrase "firmly believes" is sometimes conflated with ordinary expressions of belief in affidavits — such as "believes," "is of the belief," or "states upon information and belief." These are not equivalent. Where a statute or rule requires that the affiant "firmly believes," courts have refused to accept softer expressions of belief as substitutes. The word signals a deliberate legal threshold, not a stylistic choice. Similarly, "held and firmly bound" in bond instruments is a fixed formula; variation from it may affect the instrument's enforceability depending on jurisdiction and period.

Why It Matters in Research
Researchers working with historical pleadings, bond instruments, or appellate affidavits will encounter "firmly" as a load-bearing term, not decoration. Two traps arise frequently in historical sources:
First, statutory affidavit requirements. Where a statute specified that an affiant must "firmly believe" a proposition — common in arbitration appeal procedures — courts scrutinized the affidavit language closely. Bouvier notes that omitting "firmly" from the affidavit, even while expressing belief in substance, was held insufficient. Researchers analyzing historical arbitration appeals or appellate practice should check whether the affidavit language tracks the statutory formula exactly, and whether any substitute language was litigated.
Second, bond and recognizance instruments. The formula "held and firmly bound" appears throughout historical bond records, recognizances, and penal instruments. Black's confirms that courts treated this language as an operative acknowledgment of indebtedness. When researching historical debt instruments, suretyship disputes, or criminal recognizances, the presence of this formula — or a variation from it — may bear on how a court construed the obligation.
The term also has modest cross-jurisdictional variation in how courts treated substituted language. Pennsylvania courts (as reflected in the cases cited in Black's) took a relatively strict view of the "firmly believes" formula. Researchers should not assume uniformity across states or time periods.
Rapalje & Lawrence provides no substantive entry for this term, which is itself informative: the term's legal significance was understood to arise entirely from its placement within established formulaic phrases rather than from any freestanding doctrinal definition.

Historical Dictionary Support
Bouvier and Black's converge on the core point: "firmly" in legal instruments is a term of substance, not style. Bouvier, addressing the appellate arbitration affidavit context, states that the word "is a strong expression intended to put the affiant on his guard" and that it cannot be dispensed with unless something equal to it in substance is substituted. Black's reinforces this in the affidavit context, equating "firmly believes" with "verily believes" as expressions of a high degree of personal conviction.
Black's additionally addresses the bond formula, treating "held and firmly bound" as operative language creating an acknowledgment of indebtedness — a function that is structural to the instrument rather than merely descriptive.
What the historical dictionaries do not address: neither Bouvier nor Black's synthesizes the two usages into a unified account of why "firmly" carries legal weight in both contexts. The common thread — that the word marks a formal threshold of legal commitment, whether of personal belief or of legal obligation — is implicit but not articulated. Researchers working across both contexts should supply that connection themselves.

Jurisdictional Note
The "firmly believes" requirement in affidavit contexts arose most prominently in Pennsylvania appellate practice, as reflected in the cases Black's cites. Other jurisdictions adopted similar statutory formulas but may have applied them with varying strictness. The "held and firmly bound" formula for bonds is substantially universal in common-law jurisdictions through the nineteenth century but may be treated as a formal requirement of varying force depending on jurisdiction and period.
