Definition
Ta parti (also rendered *ta party*) is an obsolete judicial writ directed to a tenant in possession of land, commanding that person to refrain from committing waste on the property while litigation over that property was pending. The writ operated as a kind of interlocutory injunction against destructive acts — such as felling timber, demolishing structures, or exhausting mineral resources — that would diminish the value or character of the disputed land before the court had resolved the underlying claim.
The name derives from the Anglo-Norman French of the medieval common law courts and is best understood as a procedural instrument of English real property practice, not a substantive right in itself.

Common Confusion
Ta parti is sometimes loosely grouped with the writ of estrepement, which served a similar function — preventing waste during pending litigation. The two are related but technically distinct instruments within the old common law system of writs. Researchers should not assume that references to one in historical sources are interchangeable with the other. Estrepement is the more frequently encountered term in both English and early American legal writing; ta parti is considerably rarer and appears primarily in the older Register of Writs tradition.

Why It Matters in Research
This term is a historical artifact and will appear almost exclusively in pre-nineteenth-century English legal sources, early American treatises drawing on English common law, and annotated editions of the Register of Writs (*Registrum Brevium*). Researchers will not encounter ta parti as a living procedural mechanism in any modern jurisdiction.
The practical research trap here is terminological fragmentation: the function this writ performed — restraining waste during litigation — survived the abolition of the old writ system and lives on in equity jurisprudence under the heading of injunctions against waste and, in some contexts, lis pendens doctrine. A researcher tracing the history of interim relief in property disputes needs to follow the concept, not the term, once they move past the early common law period.
If you encounter ta parti in a primary source, treat it as a signal that the document predates English procedural consolidation (pre-Judicature Acts of 1873–1875) and was likely composed within or in close reference to the English Register of Writs tradition. American sources citing ta parti are almost certainly drawing on English authorities rather than reflecting any domestic practice.
The writ is notable for how narrow its operation was: it restrained only the tenant (the party in possession defending the suit), not the claimant, and it attached only during the pendency of the action. It did not resolve title; it merely preserved the subject matter of the dispute.

Historical Dictionary Support
Black's Law Dictionary provides the only significant entry among standard American legal dictionaries: "A judicial writ which used to be addressed to a tenant, prohibiting him from waste, pending suit." The citations given — *Reg. Jud. 21* and *Moore, 917* — point to the Register of Judicial Writs and to Francis Moore's law reports, both English sources from the era of the classical writ system. Black's use of the past tense ("used to be") confirms that even at the time of the dictionary's major editions, this writ was understood as extinct practice.
No significant divergence among historical sources needs to be flagged here because the term appears only in a small cluster of authorities. The scarcity itself is the finding: ta parti never achieved the jurisprudential footprint of better-known real property writs, and most legal dictionaries of both the English and American traditions do not carry it at all. Researchers relying on dictionaries alone would miss it entirely.

Jurisdictional Note
Ta parti was exclusively an English common law writ and has no recognized American counterpart or successor by that name. States that received English common law by reception statute absorbed the underlying equity principles governing waste in litigation, but through their own statutory and equitable frameworks rather than through this writ.
