Definition
A possessory action by which a party seeks either (1) to be maintained in undisturbed possession of immovable property or a real right attached to it, or (2) to be restored to possession from which the party has been evicted or divested. The term derives from the French phrase "action en complainte" as adapted into Louisiana civil law practice, where it functioned as the principal remedy for possessory disputes over land and real rights without requiring the plaintiff to establish title — only possession.
In Scots law, the soe petition (or action of soe) served a parallel function, allowing recovery or trial of possession over heritable (real) or movable property, and encompassing actions of molestation where a party's peaceable possession had been disturbed.
Two distinct legal contexts, then, share this label:
1. Louisiana possessory action: A civil-law procedural device protecting possession of immovable property or rights therein (such as servitudes), distinct from the petitory action, which litigates title.
2. Scots law possessory remedy: A broader action reaching both heritable and movable property, used to recover or vindicate possession and to try the right to possession.

Common Confusion
SOE PETITIONS vs. PETITORY ACTIONS (Louisiana): These are the paired but opposite forms of possessory litigation in Louisiana. The soe petition (possessory action) protects or restores possession and does not require proof of ownership. The petitory action litigates title directly. A plaintiff who brings a possessory action and succeeds cannot immediately bring a petitory action for the same property — Louisiana law historically required election between these remedies. Researchers who conflate the two will misread case outcomes: a judgment in a soe petition says nothing about who owns the land.
SOE PETITIONS vs. GENERAL PETITIONS: The word "petition" in the constitutional sense — the right to petition government — is entirely unrelated. See the ENCYCLOPEDIA CROSS-REFERENCE entries below for that distinct body of law.

Why It Matters in Research
This term presents two significant research traps.
First, the label is jurisdiction-specific and rare in modern usage. Louisiana abandoned the distinct "soe petition" label as part of its 20th-century procedural reforms; what was once styled as a soe petition is now governed by the Louisiana Code of Civil Procedure articles on possessory actions. Researchers searching pre-reform Louisiana reports (pre-1960) under "possessory action" may miss cases captioned under "soe" or "complainte," and vice versa. The early Louisiana Reports (the period covered by citations like 2 La. 227) use terminology drawn directly from French and Spanish civil law antecedents, and the vocabulary is not consistent across decades.
Second, researchers working in Scots law sources face a different problem: the action of soe overlaps with, but is not identical to, the interdict (the Scots equivalent of an injunction against interference with possession) and the action of molestation. Bouvier's entry notes molestation specifically, signaling that the soe petition in Scots practice could shade into what Anglo-American lawyers would call a nuisance or trespass action. Cross-referencing between Scots institutional writers (Stair, Erskine, Bell) and American secondary sources on Louisiana law is necessary when the origin of a Louisiana doctrine is in dispute, since Louisiana drew from both French and Scots civilian traditions.
For corpus researchers: Louisiana possessory action materials cluster in the early Louisiana Reports and in civil law treatises on real rights. Scots law materials on this point are found in institutional writers and not typically in American legal dictionaries beyond Bouvier. The term does not appear with any regularity in common law jurisdictions, so finding it in a non-Louisiana, non-Scots source is a signal worth investigating carefully — it may indicate a transplanted civil law concept or a drafting error.

Historical Dictionary Support
Bouvier's Law Dictionary is the only major American legal dictionary to carry this term, which itself reflects how narrowly the label circulated outside Louisiana and Scots law practice. Bouvier's treatment is concise but accurate in identifying the dual function — maintenance in possession and restoration after eviction — and in noting the Scots law parallel. The citation to 2 La. 227, 254 grounds the Louisiana definition in early appellate authority.
What Bouvier's does not address: the procedural consequences of electing the possessory over the petitory action, the time limits that governed when a disturbed possessor had to act, or the evidentiary standard for proving "possession" sufficient to support the action. Those details are critical for reading the cases and are found in Louisiana civil law treatises of the 19th century rather than in dictionary form. Bouvier's also does not distinguish between possession of the thing itself and possession of a real right (such as a servitude or usufruct) over another's property — a distinction the Louisiana courts treated as significant.
No entry appears in Black's Law Dictionary under this specific label, which confirms that the term never achieved general American common law circulation.

Jurisdictional Note
The soe petition is a creature of Louisiana civil law and Scots law. It has no recognized counterpart in common law jurisdictions. Researchers applying this concept outside Louisiana or a Scots law context should proceed with caution — the underlying doctrine of possessory protection exists in equity and in some statutory forms across common law states, but under entirely different labels and procedural rules.
