Definition
In the historical law of bills of exchange, the *trassatus* is the party upon whom a bill of exchange is drawn — that is, the drawee. The term denotes the person directed by the drawer to pay a specified sum to a third party (the payee or holder) upon presentment of the instrument. The trassatus becomes liable on the instrument only upon acceptance; before acceptance, the bill is merely an order addressed to that party, not a binding obligation upon them.
The term is Latin-form legal vocabulary derived from the medieval mercantile law tradition and appears in civil law and early commercial law sources. It functions as the Latin equivalent of the English *drawee*.

Common Confusion
TRASSATUS vs. TRASSANS: These two terms are easily conflated. The *trassans* (or *trahens*) is the drawer — the party who creates and signs the bill of exchange, ordering payment. The *trassatus* is the drawee — the party upon whom the order is made. The confusion is natural because both terms derive from the same Latin root (*trassare*, to draw), but they represent opposite roles in the transaction. In research, substituting one for the other inverts the legal relationship entirely.
TRASSATUS vs. ACCEPTOR: Once the trassatus formally accepts the bill — typically by signing it — they become the acceptor and take on primary liability for payment. The trassatus and acceptor are the same person at different stages of the instrument's life. Historical sources do not always distinguish these stages clearly.

Why It Matters in Research
This is a term of historical and comparative commercial law, not modern practice. No contemporary American or English practitioner uses *trassatus*; researchers will encounter it exclusively in early treatises, civil law sources, and pre-nineteenth-century materials on the law of bills of exchange.
The key navigational point: *trassatus* appears most frequently in sources drawing on continental European commercial law — particularly the ius commune tradition and German pandectist scholarship. The citation shared across all three source dictionaries (Heineccius, *De Cambiis*, c. 6, §§ 5–6) points to Johann Gottlieb Heineccius, an eighteenth-century German jurist whose work on exchange law circulated widely in both civilian and common law contexts. Researchers tracing the doctrinal ancestry of Anglo-American bills of exchange law will find this term at the intersection of those traditions.
When reading historical treatises on negotiable instruments, particularly those translated from Latin or drawing on civilian sources, the presence of *trassatus* signals that the author is working in a civil law register. This affects how terms like acceptance, liability, and recourse are structured in the surrounding text — civilian sources frequently impose different default rules than common law sources on questions such as the effect of presentment and the trassatus's right to refuse acceptance.
Corpus researchers should note that Burrill explicitly cross-references *trassare* as the root verb, suggesting that Law Mind's corpus may contain related entries under that headword. Checking *trassare*, *trassans*, and *trahens* will recover the full terminological network for parties to a bill of exchange in civil law sources.

Historical Dictionary Support
All three source dictionaries are in near-complete agreement: *trassatus* means the drawee of a bill of exchange. Black's (1st and 2nd editions) are essentially identical in their treatment, offering a one-sentence definition with the same Heineccius citation. Burrill adds the derivation note (*from trassare*) and the Latin-language classification marker (*L. Lat.*), which is the most substantively useful addition — it confirms this is Law Latin, not classical Latin, and situates the term in the medieval mercantile law tradition rather than Roman law proper.
None of the three dictionaries elaborate on the distinction between the trassatus before and after acceptance, nor do they situate the term within the broader party structure of a bill of exchange (drawer, drawee, payee). That context must be reconstructed from the surrounding entries and from primary sources like Heineccius. Researchers should treat these dictionary entries as finding aids rather than complete expositions of doctrine.
