Definition
In French maritime law, the affreteur is the party who hires a vessel — the charterer or affreighter. The term designates the person who engages a ship (or its cargo space) from the shipowner under a contract of affreightment, typically a charter party. The affreteur stands in contrast to the fréteur, who is the shipowner or the party supplying the vessel.
The term is French in origin and appears in English-language legal sources primarily in admiralty and maritime law contexts, where French commercial law concepts were influential, particularly in discussions of insurance, charter parties, and cargo liability.
Common Confusion
Affreteur is sometimes loosely equated with "shipper" in older sources, but the two are distinct. A shipper is the party who delivers goods for carriage; an affreteur is the party who hires the vessel itself. In a charter party arrangement, the affreteur controls the vessel or its capacity under contract — a shipper booking space on a liner does not hold that contractual position. The conflation is more likely in historical texts that do not carefully distinguish charter party relationships from ordinary cargo contracts.
Why It Matters in Research
This is a narrow, jurisdiction-specific term drawn from French civil and commercial law. Researchers will encounter it almost exclusively in three contexts: (1) admiralty law treatises and digests from the eighteenth and nineteenth centuries that drew heavily on French maritime codes and commentators, particularly Emerigon; (2) charter party disputes in which French or civil-law sources were cited for comparative or persuasive authority; and (3) historical insurance law, where the rights and liabilities of the affreteur as against the fréteur and underwriters were analyzed in detail.
The key navigational trap is that this term rarely appears in common law case reporters under this spelling. Researchers searching for the concept in English-language sources should search instead under "affreighter," "charterer," and "charter party." The French form affreteur signals that a source is either translating or directly citing French maritime authority — Emerigon's Traité des Assurances in particular — rather than stating settled common law doctrine.
Burrill cross-references the term to Emerigon (des Assurances, ch. 11, sect. 3), which is the locus classicus for the civil-law treatment of the affreighter's rights and obligations. Researchers working in nineteenth-century American or English admiralty contexts who encounter affreteur should treat it as a signal to consult the civilian maritime tradition, not the common law line.
Historical Dictionary Support
Burrill's Law Dictionary gives the entry concisely: "Fr. In French law. The hirer of a vessel; the affreighter," citing Emerigon. This is the full scope of treatment in the English-language historical dictionaries — none of the major common law dictionaries (Black's early editions, Bouvier, Jacob) give the term independent treatment, reflecting its status as a borrowed term of art rather than a naturalized common law concept.
Burrill's placement of the entry is also informative: the immediate following entry covers affri (plough cattle under old English law), underscoring that affreteur is catalogued as a foreign-law term rather than integrated doctrine. The historical dictionaries agree on the definition but provide no doctrinal development, which accurately reflects the term's role as a reference point for civil-law sources rather than a working term in English courts.
Jurisdictional Note
The term is operative in French and civil-law maritime jurisdictions. In Louisiana, where civil law tradition persists, affreteur and related French maritime concepts have greater direct relevance than in other American states. In admiralty practice generally, the functional concept is fully covered by "charterer" and "affreighter" without resort to the French term.
