Definition
An obsolete common law writ authorizing the seizure of goods held by a party during the pendency of a lawsuit, for the purpose of preventing those goods from being concealed, transferred, or otherwise disposed of before judgment could be enforced. The writ operated as a form of pre-judgment security measure, ensuring that assets subject to litigation remained available to satisfy any eventual judgment.

Common Confusion
Sipentur is easily confused with several other writs affecting property during litigation. Distringas compelled appearance or compliance through seizure of goods but served a different procedural function. Sequestration was an equitable remedy available in Chancery. Attachment in modern usage overlaps with sipentur's functional purpose but is a creature of statute and rule, not of the original writ system. The specific identity of sipentur — targeting goods in a party's hands to prevent their being made away with during suit — should be kept distinct from these related but non-identical mechanisms.

Why It Matters in Research
Sipentur is a term a researcher will encounter only in historical sources and period-specific legal materials. It has no modern procedural counterpart by that name, having been supplanted by statutory and equitable mechanisms for pre-judgment attachment and injunctive relief. Researchers working in medieval or early modern English legal records, plea rolls, or registries of writs should recognize sipentur as functionally analogous to what modern practice achieves through attachment, sequestration, or a freezing injunction — but the legal machinery and terminology are entirely distinct.
The primary trap in historical research is conflating sipentur with other writs that similarly restrained property during litigation, including distringas, sequestration, and replevin. Each had distinct procedural triggers and contexts. Sipentur was specifically directed at goods in the hands of a party to the suit, and its purpose was prophylactic: preventing dissipation pending judgment rather than compelling an act or recovering already-transferred property.
Because both editions of Black's Law Dictionary cite the Registrum Omnium Brevium (Reg. Orig.) as authority — with the first edition citing page 126 and the second edition citing folio 126b — researchers tracing the writ to primary sources should consult that register directly. The Registrum Omnium Brevium is a real historical compilation of standard English writ forms and is available in facsimile and scholarly editions. Discrepancies between editions of Black's in the folio citation (126 vs. 126b) are minor and likely reflect different pagination conventions or editions of the Registrum consulted.
This term will not appear in modern procedural codes, rules of civil procedure, or contemporary case law. Its relevance is almost exclusively historical and documentary.

Historical Dictionary Support
Both editions of Black's Law Dictionary provide nearly identical definitions, differing only in the page reference to the Registrum Omnium Brevium. Neither edition provides additional context about the writ's origins, the courts in which it issued, or the historical period of its active use. This sparseness reflects the writ's status as an archaic curiosity rather than a term requiring extended treatment — both editions classify it as "an old writ," signaling that even at the time of publication it was no longer in practical use.
Neither edition addresses the relationship between sipentur and contemporary equitable remedies, nor do they situate the writ within the broader taxonomy of English writs concerned with property preservation. Researchers should not treat Black's entries here as exhaustive; the Registrum Omnium Brevium and secondary scholarship on early English civil procedure will provide more complete context.

Jurisdictional Note
Sipentur was an English common law writ with no known direct reception into American, colonial, or other common law jurisdictions as a named form. American courts developed their own pre-judgment attachment procedures through statute. Researchers should not assume sipentur appears in American legal sources.
