Definition
The attachment of the forest was the lowest of three courts historically convened within the royal forests of England. It served as a tribunal of first instance for offenses against forest law — principally trespass, illegal hunting, and violations of the rules governing use of the king's forest. Cases arising in the attachment court could be escalated to higher forest tribunals depending on their severity.
The three-tiered hierarchy of forest courts was as follows: the attachment court occupied the lowest rung, the swainmote (or swanimote) stood in the middle, and the justice in eyre's seat — also called the court of justice seat — sat at the highest level. Manwood's treatise on forest law (circa 1598) described all three and remains the primary historical authority on their structure.
The attachment court convened frequently — typically every forty days — and was presided over by the foresters and verderers. It recorded offenses and detentions but generally lacked authority to impose final punishment, referring more serious matters upward. The court's name reflects the procedural mechanism at its core: offenders and their animals or goods were "attached," meaning seized or bound over, pending further adjudication.

Common Confusion
The word "attachment" appears in three distinct legal contexts that researchers may conflate. First, in civil procedure, attachment refers to the prejudgment seizure of a defendant's property to secure a potential judgment — an entirely separate doctrine covered in The Law Mind Civil Procedure & Evidence Encyclopedia (civpro_118). Second, in criminal procedure, attachment refers to the point at which jeopardy attaches for double jeopardy purposes — again, a wholly unrelated concept (criminal_170). The attachment of the forest belongs to neither of these traditions. It is a discrete institution of medieval English forest law, defined by its judicial function rather than by any seizure of property as an end in itself.

Why It Matters in Research
This term is essentially a dead letter in modern law. No jurisdiction retains forest courts in this form, and no contemporary doctrine descends directly from the attachment court's procedures. Researchers will encounter it almost exclusively in the following contexts:
Historical legal history and constitutional history. The forest courts represent one of the earliest examples of specialized administrative tribunals in the English legal tradition — courts whose jurisdiction was defined by subject matter (royal forest offenses) rather than by geography or general law. Researchers tracing the genealogy of regulatory or administrative adjudication may find this institution instructive.
Primary sources from medieval and early modern England. Chronicles, forest rolls, and administrative records from the twelfth through seventeenth centuries reference the attachment court regularly. Readers of these sources need to understand that "attachment" in this context does not signal a writ of civil attachment or any modern procedural device.
Comparative forest and land law. Researchers examining the historical roots of public land management, wildlife law, or conservation easements sometimes trace English forest law as a point of origin. The attachment court is a node in that history, illustrating how the Crown enforced exclusivity over natural resources long before modern regulatory frameworks.
The key trap: do not read "attachment" here through a modern civil procedure lens. The forest attachment was a court, not a writ, and not a remedy.

Historical Dictionary Support
Black's Law Dictionary provides the foundational entry, citing Manwood at pages 90 and 99. The entry is brief but accurate: it names all three forest courts, places the attachment at the lowest tier, and correctly identifies the justice in eyre's seat as the highest. The citation to Manwood — John Manwood's A Treatise and Discourse of the Lawes of the Forrest (first published 1598, expanded editions in 1615) — is the appropriate primary authority for this subject and is one of the few systematic treatments of English forest law.
What Black's does not do is explain the court's procedure, its frequency of sitting, the role of verderers and foresters as officers, or the relationship between the attachment and the administrative machinery of the royal forest. Researchers who need more than a structural identification will need to consult Manwood directly, or secondary works on medieval English forest administration.
Other historical dictionaries in the Law Mind shelf do not appear to carry independent entries for this term, which is consistent with its narrow scope. This is an area where Black's, drawing on Manwood, exhausts what the dictionary shelf can offer.

Jurisdictional Note
This is a purely historical English institution with no direct American counterpart. U.S. public land law developed through entirely different channels — the General Land Office, the National Forest System, and statutes such as the National Forest Management Act — without inheriting the forest court structure. The term has no operative meaning in any current U.S. or Commonwealth jurisdiction.
