Definition
"Duly prosecute" is a term of art appearing primarily in replevin bonds and similar surety instruments. It obligates the party who has obtained a writ of replevin — the return of seized personal property pending litigation — to pursue the underlying action diligently and in good faith through the court system. The covenant is a condition of the bond: if the plaintiff fails to duly prosecute, the bond may be forfeited and the defendant may recover damages.
The phrase does not require a favorable outcome. It requires active, timely pursuit of the claim through the available proceedings. Courts have held that the covenant is satisfied when the plaintiff prosecutes the case to judgment at trial and carries any appeal through the appellate courts, even if the plaintiff ultimately loses. The obligation is procedural in character — it is about maintaining the lawsuit, not winning it.
More generally, "duly prosecute" appears in procedural contexts outside replevin to describe the obligation of a party to advance a pending action without unreasonable delay or abandonment.
Common Language
Modern common usage (Wiktionary): "Duly" means in a proper or appropriate manner; in accordance with what is required. "Prosecute" in common usage means to bring a criminal charge against someone, or more broadly, to carry out or pursue something.
Historical common usage (Webster's 1913): "Prosecute" — "To follow or pursue with a view to reach, execute, or accomplish; to carry on; to continue; as, to prosecute a journey; to prosecute an enterprise." "Duly" — "In a due, fit, or becoming manner; as it ought to be; properly; regularly."
The gap matters here. In everyday speech, "prosecute" almost always signals criminal proceedings. In this legal context, "duly prosecute" has nothing to do with criminal law. It is a civil obligation — a bonded promise to actively maintain a lawsuit. A researcher encountering this phrase in historical court records or pleadings must read it as a contractual duty imposed on a civil plaintiff, not as a reference to any government's criminal charging function.
Common Confusion
"Duly prosecute" is frequently misread as referring to criminal prosecution. The confusion is understandable: modern readers associate prosecution with the state's pursuit of criminal defendants. But in the context of a replevin bond or similar civil instrument, "prosecute" carries its older, broader meaning — to pursue a legal action to its conclusion. Conflating the two meanings can lead researchers to misclassify civil bond forfeitures as criminal proceedings in historical records.
Why It Matters in Research
The primary research context for "duly prosecute" is historical civil procedure, particularly replevin actions and surety bond litigation. Several navigational points are worth noting:
First, the phrase appears in a narrow but recurring slice of the Law Mind corpus: bond conditions, replevin pleadings, and surety disputes. If you encounter it in a 19th or early 20th century court record, look first to whether a writ of replevin is in the procedural background. The Bouvier citation to a Kentucky case (128 Ky. 506) confirms this was a live question in state appellate courts well into the early 20th century.
Second, the standard for satisfying the covenant evolved in case law. Bouvier's entry affirms that prosecuting through both the trial court and the court of appeals satisfies the duty. But earlier or later jurisdictions may have applied different standards. Researchers should not assume the Kentucky rule applies universally.
Third, the phrase "duly prosecute" has a temporal dimension that is easy to miss. It is not merely a duty to file a lawsuit — it is a duty to continue pursuing it. Voluntary dismissal, abandonment, or undue delay could constitute a breach of the covenant even if the action was properly commenced.
Fourth, Bouvier's entry for "duly prosecute" is immediately followed by the entry for DUM BENE SE GESSERIT — a Latin phrase concerning judicial tenure during good behavior. This is a layout artifact. The two terms are unrelated; researchers should not read any conceptual connection between them.
Historical Dictionary Support
Bouvier's Law Dictionary is the primary historical source for this term in the Law Mind corpus. Bouvier does not offer an abstract definition; instead, it immediately grounds the phrase in a specific legal proposition: the replevin bond covenant is satisfied by prompt prosecution through both the circuit court and the court of appeals. This is a characteristically practical Bouvier entry — rule-oriented, case-anchored, jurisdiction-specific.
What Bouvier does not address: the phrase's broader use outside replevin bonds, any discussion of what constitutes a breach of the covenant, or the remedies available upon forfeiture. Researchers looking for those dimensions will need to go beyond the historical dictionaries into treatises on suretyship or state-specific replevin statutes.
No other major historical dictionaries in the Law Mind shelf (Black's, Cyclopedic Law Dictionary, Stroud's, or Wharton's) appear to have a dedicated entry for this phrase, making Bouvier's the authoritative historical reference point in this corpus.
Jurisdictional Note
The covenant to "duly prosecute" in replevin bonds was governed by state law, and the standard for satisfaction varied by jurisdiction. The Bouvier formulation draws from Kentucky practice. Other states may have required prosecution only through trial court judgment, or may have defined "duly" by reference to local rules on continuances and dismissals. Federal courts applying state replevin law would follow the applicable state standard.
