Definition
Domiciled describes a person, entity, or legal instrument as having been established in, or as belonging to, a particular place by right of domicile. To say that a party is domiciled in a jurisdiction means that jurisdiction is recognized as their permanent legal home — not merely where they happen to be physically present, but where they have fixed their legal residence with the intention to remain indefinitely.
Domicile itself is distinct from residence or citizenship. A person has only one domicile at any given time. Being domiciled somewhere carries legal consequences for personal jurisdiction, choice of law, taxation, inheritance, divorce proceedings, and in some contexts the right to sue or be sued in a particular forum.
For legal entities such as corporations or insurance companies, "domiciled" refers to the jurisdiction of incorporation or primary regulatory organization — the state that has formal authority over that entity's charter and governance.

Common Language
Modern common usage (Wiktionary): Simple past and past participle of the verb "domicile" — i.e., to have established a domicile somewhere.
Historical common usage (Webster's 1913): "Domicile" as a noun meant a dwelling place or home; as a verb, to establish or fix a residence.
The gap between common and legal meaning is not sharp in vocabulary, but it is significant in consequence. Ordinary usage treats "domiciled" as little more than a synonym for "lives in" or "is based in." Legal usage carries a stricter test: physical presence alone is insufficient. Intent — specifically, the intent to make a place one's permanent home without a present plan to leave — is essential to the legal determination. A person can be physically present in a state for years without being legally domiciled there, and conversely can retain a domicile in a jurisdiction they have temporarily left.

Common Confusion
DOMICILED vs. RESIDENT: These terms are frequently conflated in both lay and legal writing. Residence requires only physical presence with some degree of regularity; domicile requires both presence and intent to remain permanently. A person can have multiple residences but only one domicile.
DOMICILED vs. CITIZEN (in federal diversity jurisdiction): In federal court diversity analysis, "citizenship" for the purposes of 28 U.S.C. § 1332 is determined by domicile for natural persons — the two terms are sometimes used interchangeably in this context, which can confuse researchers. For corporations, citizenship is determined differently (state of incorporation plus principal place of business), making the conflation especially dangerous when researching entity-based diversity cases.

Why It Matters in Research
Domiciled is a participial adjective and the operative word in hundreds of jurisdictional and conflict-of-laws contexts. Researchers need to track several distinct pressure points:
First, the word appears in older sources as a near-synonym for "inhabitant" or "resident," without the modern precision about intent. Pre-twentieth-century cases and treatises often use domiciled loosely; do not assume the modern two-part test (presence plus intent) was uniformly applied in historical materials.
Second, in family law research — particularly divorce jurisdiction — domicile is frequently the fulcrum of the entire analysis. Courts require at least one spouse to be domiciled in the forum state for the court to have subject matter jurisdiction to dissolve the marriage. The Law Mind Family Law Encyclopedia entry on divisible divorce addresses this directly and is essential background for any research touching divorce jurisdiction or the recognition of foreign decrees.
Third, in insurance regulatory research, "domicile" determines which state's insurance department has primary supervisory authority over an insurer. For captive insurance structures in particular, domicile selection is a strategic regulatory decision with significant compliance consequences. The Law Mind Insurance Law Encyclopedia entry on captive insurance formation covers this in detail.
Fourth, for federal diversity jurisdiction research, traps multiply when parties have recently moved, maintain residences in multiple states, or when the relevant date for domicile determination is disputed. Domicile is assessed as of the time the complaint is filed, not at the time of the underlying events — a distinction that catches researchers who read the facts rather than the procedural posture.
Fifth, for corporations and other entities, "domiciled" in older authorities often meant state of incorporation exclusively. Modern doctrine and statutory frameworks sometimes distinguish state of incorporation from principal place of business; researchers should not assume that historical usage of "domiciled" for an entity maps cleanly onto modern citizenship analysis.

Historical Dictionary Support
Both the first and second editions of Black's Law Dictionary offer identical, minimal entries: "Established in a given domicile; belonging to a given state or jurisdiction by right of domicile." The entries are consistent but thin — they confirm the legal meaning without explaining the intent requirement or distinguishing domicile from residence. Neither edition addresses the multi-context application of the term (family law, diversity jurisdiction, corporate law, insurance regulation), nor do they flag the evidentiary complexity of proving intent.
What the historical sources miss is instructive: the entire body of doctrine establishing how domicile is proven, what evidence suffices to establish intent, and how courts resolve conflicting claims of domicile in multi-state disputes is absent from the dictionary record. Researchers relying solely on dictionary entries for this term will find themselves with a correct but skeletal understanding. The substantive doctrine lives in treatises, Restatement provisions, and case law rather than in lexicographic sources.

Jurisdictional Note
While the basic definition of domicile is consistent across American jurisdictions, states vary in evidentiary standards for proving domicile, required periods of residency before domicile is presumed established for divorce purposes, and treatment of domicile for estate and inheritance tax purposes. Researchers working across state lines should verify the specific forum's formulation rather than assuming uniform application.
