Definition
Solutione feodi militis par is a Latin phrase from medieval English law meaning "for the payment of a knight's fee." It designates a writ — or the basis of a writ — directed at securing payment of a knight's fee, the foundational unit of feudal military tenure by which a tenant held land from a lord in exchange for military service or its monetary equivalent. The phrase appears in the context of feudal tenure obligations and the legal mechanisms used to enforce or acknowledge them.
A knight's fee (feudum militis) was not a fixed monetary sum but rather a standard of land holding sufficient to support one knight for military service, typically assessed at a certain acreage or value. Solutione feodi militis par thus references the process of satisfying — paying out or settling — the obligations attached to that tenure unit.

Why It Matters in Research
This term is a navigational challenge for several reasons. First, it survives almost exclusively in Latin, as it belongs to the period of English legal practice when writs and pleadings were recorded in Latin before the Proceedings in Courts of Justice Act 1730 (which mandated English). Researchers encountering this phrase in original records, plea rolls, or early treatise compilations should expect no English vernacular equivalent in contemporaneous sources.
Second, the term is closely tied to the writ system of medieval common law and the forms of action. Understanding solutione feodi militis par requires situating it within the broader machinery of feudal tenure obligations — specifically the processes by which lords enforced payment of scutage (shield money paid in lieu of military service) or by which tenants satisfied fee-based obligations. It is not a freestanding cause of action in the modern sense but rather a Latin descriptor appearing in writ formularies.
Third, the source dictionaries cross-reference this term under LIAMENTI or FEODI BURGENSIS — suggesting that researchers who find this phrase in the wild may need to navigate between overlapping taxonomies of feudal fees (knight's fees, burgage fees, and related tenure categories). The apparent mismatch between the headword and the dictionary entry content is itself a research trap: do not assume the definitions indexed under LIAMENTI will fully explain the knight's fee context.
Finally, because knight's fees were abolished as a tenure category in England by the Tenures Abolition Act 1660, this term has no living legal application in common law jurisdictions. Its relevance is entirely historical — primarily for researchers working in medieval land law, feudal obligations, Chancery or Exchequer records, or early common law writ forms.

Historical Dictionary Support
Both editions of Black's Law Dictionary index this term but direct the reader to the entry for LIAMENTI, or FEODI BURGENSIS rather than providing a standalone definition. This is a notable limitation: LIAMENTI and FEODI BURGENSIS concern burgage tenure — a distinct form of feudal holding associated with towns and boroughs — rather than the military tenure that solutione feodi militis par directly concerns. The cross-reference may reflect a compositor's grouping of Latin fee-related terminology without distinguishing between tenure types, or it may indicate that the writ appeared in contexts where both burgage and knight's fees were at issue.
Neither edition of Black's provides a substantive gloss on the writ's procedure, its history in the plea rolls, or its relationship to scutage. For genuine depth on the subject, researchers should look to Bracton's De Legibus et Consuetudinibus Angliae, Glanvill's Tractatus de Legibus et Consuetudinibus Regni Angliae, and Littleton's Tenures — the primary medieval and early modern authorities on feudal tenure — as well as Pollock and Maitland's The History of English Law Before the Time of Edward I, which remains the authoritative modern synthesis on the feudal tenure system in England.
The historical dictionaries' treatment here is thin by design: by the time Black's first edition appeared (1891), feudal military tenure had been formally abolished for over two centuries, and the term was already purely antiquarian.

Jurisdictional Note
This term has no operative legal significance in any modern jurisdiction. Its relevance is confined to English legal history prior to 1660. American law inherited English common law but not the feudal tenure system in its original form; colonial land grants departed from knight's fee structures from the outset.
