Definition
A regime, in legal usage, is a structured system of rules, regulations, or legal arrangements governing a defined subject matter or relationship. The term carries two primary senses in legal research:
1. A legal or regulatory framework. A coordinated body of rules, statutes, treaties, or doctrines that collectively govern a field — as in a "trade secret regime," an "intellectual property regime," or an "international sanctions regime." Used this way, regime is an analytical shorthand for the totality of operative legal rules within a domain.
2. A system of marital property governance (historical French law context). In civil law systems derived from French practice, regime refers specifically to the rules governing the property relationship between spouses. The régime dotal, for example, governed the dot — property contributed by the wife toward the burdens of marriage — and set the terms under which that property was administered, alienated, or returned. Other recognized marital property regimes under French-influenced civil law include the régime de communauté (community of property) and regimes of separation of property.
The second sense is largely historical in common law research but remains directly relevant in Louisiana, Quebec-influenced jurisdictions, and comparative civil law materials.

Common Language
Modern common usage (Wiktionary): A mode of rule or management; a form of government, particularly an authoritarian or totalitarian one; a period of rule; a regulated system.
Historical common usage (Webster's 1913): "Mode or system of rule or management; character of government, or of the prevailing social system."
In ordinary usage, regime carries a political and often pejorative charge — it frequently implies authoritarian governance. Legal usage strips this connotation entirely. When lawyers and courts write of a "regulatory regime" or a "statutory regime," they mean nothing more than a structured system of rules. The gap matters: researchers encountering regime in political science or journalistic sources should not import the evaluative overtones into legal analysis.

Recognized Forms
/SUBTYPES
Marital property regimes (civil law tradition):
- Régime dotal: Wife's property (the dot) contributed to the marriage placed under regulated administration, typically by the husband, with protections on alienation.
- Régime de communauté: Community of property shared between spouses, with variations governing what property enters the community and how it is divided.
- Régime de séparation de biens: Each spouse retains separate ownership of property acquired before and during the marriage.
Regulatory/statutory regimes (modern usage):
- Intellectual property regime: The body of law — copyright, patent, trademark, trade secret — governing rights in creative and informational goods. Frequently discussed as overlapping or competing regimes.
- Sanctions regime: A coordinated framework of economic and trade restrictions imposed by statute, executive order, or treaty.
- Environmental regime: The statutory and regulatory framework governing pollution, resource use, or conservation obligations.
These subtypes are not exhaustive; "regime" functions as a productive legal compound across nearly every area of law.

Why It Matters in Research
The principal research challenge with regime is its dual life as a term of art and a general analytical descriptor. Because it appears across bodies of law with no single controlling definition, researchers must anchor the term to its context.
In IP research specifically, the word regime signals structural analysis — courts and scholars use it when comparing how different bodies of IP law interact, overlap, or conflict. The preemption question in trade secret law, for example, turns on whether federal copyright law displaces state trade secret protection, which requires mapping each "regime" and identifying points of conflict. The Law Mind encyclopedia entries at ip_95 and ip_111 use regime in exactly this analytical sense; researchers working preemption or remedies questions should treat regime as an index term pointing to framework-level analysis rather than rule-level doctrine.
In historical sources and in civil law materials, regime appears in the marital property context. Researchers working Louisiana law, community property history, or comparative civil law will encounter régime dotal and cognate terms in French-language sources and in translations. Black's (2nd Ed.) flags the French law origins directly; this reflects the late nineteenth and early twentieth century practice of including civil law terminology that had practical relevance in Louisiana and in courts that occasionally adjudicated French-law-governed transactions.
Rapalje & Lawrence does not carry an entry for regime, which is characteristic — their dictionary focuses on terms as judicially defined in specific cases, and regime does not generate that kind of definitional litigation. The absence is itself useful: it confirms that regime functioned more as legal vocabulary than as a contested term requiring judicial construction.
Researchers using keyword searches in historical corpus materials should note that the accented form régime appears in older texts and French-derived sources, while regime (no accent) dominates modern American legal writing. Both forms should be searched.

Historical Dictionary Support
Black's (2nd Ed.) treats regime primarily through the French law marital property lens, defining régime dotal with reasonable precision and noting that the dot may extend to future as well as present property. This reflects the civilian tradition that Black's, like many late nineteenth-century American dictionaries, felt obliged to document given Louisiana's ongoing relevance to commercial and property law.
Rapalje & Lawrence does not define regime, which tells its own story: the term was not doing definitional work in reported Anglo-American case law in the way that REFUSE, REGARDS, or REFUSE WOOD were. Those entries reflect the dictionary's case-based methodology — define the word as a court has construed it. Regime, as a structural descriptor rather than a word in a deed, will, or statute requiring construction, largely escaped that treatment.
Neither source anticipates the modern regulatory-framework usage, which is a twentieth-century development driven by administrative law expansion and international law scholarship. Researchers should not expect historical dictionary support for the term in its modern dominant sense.

Jurisdictional Note
The marital property regime terminology retains direct legal force in Louisiana, which continues to apply a civil law framework to matrimonial regimes. The Louisiana Civil Code titles governing matrimonial regimes represent a living body of law, not an archaic curiosity. Researchers applying Louisiana family or property law should treat the civilian regime vocabulary as operative doctrine, not historical background.
