Definition
Assignation has two distinct legal senses, one jurisdictionally specific and one now largely archaic in Anglo-American practice.
1. Scots Law: The standard Scots law term for what English and American law calls an assignment — that is, the transfer or conveyance of a right, debt, or movable subject from one party (the assignor or cedent) to another (the assignee). In Scots legal usage, assignation is distinguished from disposition, which is the conveyance of heritable (real) property. Assignation properly refers to the written deed by which a proprietor transfers any subject not heritable in character — debts, personal rights, leases, and movables. The governing maxim is assignatus utitur jure auctoris: an assignee stands in the shoes of the assignor and acquires no greater right than the assignor held.
2. General (archaic): In older English legal usage, assignation could function as a synonym for assignment in the broader sense — the act of allotting, appointing, or transferring title. This usage has almost entirely disappeared from modern legal writing in England and the United States, where assignment is now the universal term.

Common Language
Modern common usage (Wiktionary): An appointment for a meeting, generally of a romantic or sexual nature; also, more broadly, the act of assigning or allotting.
Historical common usage (Webster's 1913): "An appointment of time and place for meeting or interview — used chiefly of love interviews, and now commonly in a bad sense." Webster's also acknowledged the legal sense: "a making over by transfer of title; assignment."
The gap here is significant and runs in both directions. A modern reader encountering assignation in a general context will almost certainly read it as referring to a clandestine romantic meeting. A researcher encountering the term in historical legal sources — particularly Scots law materials — must read it in precisely the opposite register: as a formal, technical instrument of conveyance. The romantic connotation has no legal content whatsoever. The legal connotation has no romantic content whatsoever. Do not let the common meaning bleed into source interpretation.

Common Confusion
Assignation and assignment are substantively equivalent in meaning but are not interchangeable across legal traditions. Assignment is the correct term in English and American law; assignation is the correct term in Scots law. Using assignment when analyzing a Scottish deed or treatise is not wrong, but it signals an outsider's vocabulary. More importantly, researchers working with historical Anglo-American sources occasionally encounter assignation used loosely as a synonym for assignment — this is a period affectation, not a term of art carrying distinct legal weight in that context.
Do not confuse assignation with assignee (the person receiving the transfer) or with assignor (the person making the transfer). These are party designations, not the name of the act or instrument.

Why It Matters in Research
The primary research trap is jurisdictional. Assignation is operative legal vocabulary in Scots law sources — Erskine's Institutes, Bell's Dictionary and Digest of the Law of Scotland, and their successors. Researchers working in Scottish legal history, Scottish private law, or comparative common law contexts will encounter this term constantly. In those sources it is not an archaic curiosity; it is the working term. Reading it as anything other than a formal transfer instrument will distort analysis.
For researchers working in English or American legal history, assignation appears occasionally in older materials (pre-nineteenth century in particular) as a synonym for assignment. When you encounter it in this context, treat it as assignment and move on — it carries no additional technical load.
The maxim assignatus utitur jure auctoris, which all the historical dictionaries attach to this entry, is worth noting independently. It is a substantive rule, not mere decoration: the assignee takes subject to all defenses, equities, and limitations that could have been raised against the assignor. This principle is alive in modern contract and property law under the general law of assignment, even where the Latin has long since dropped out of usage.
Researchers following a chain of title or rights transfer through historical Scottish records should be alert to the distinction Burrill draws between assignation (movables and personal rights) and disposition (heritable subjects). Conflating the two in a historical conveyancing context could lead to misreading the nature of the property being transferred.
Finally, note the non-legal meaning of assignation in historical literary and general sources. If you are working with mixed archives — correspondence, diaries, legal instruments together — context is essential. The same word in the same document collection may be doing entirely different work depending on who wrote it and for what purpose.

Historical Dictionary Support
The historical dictionaries are unanimous on the core point: assignation is the Scots law equivalent of assignment, and all five sources say so explicitly or by direct cross-reference. There is no meaningful divergence among them on this.
Burrill provides the most useful additional content. He draws on Erskine's Institutes to specify that assignation is properly understood as a written deed of conveyance of any subject not feudal (i.e., not heritable), and he cites Bell's Dictionary for the distinction from disposition. This is the granular distinction that the other dictionaries elide by simply pointing the reader to assignment.
Black's (both editions) and Rapalje & Lawrence each reproduce the maxim assignatus utitur jure auctoris with attribution to Halkerson's Maxims and Broom's Legal Maxims — citations to real treatises, useful for researchers wanting to trace the principle in primary authorities.
What the historical dictionaries do not do is explain the modern irrelevance of assignation in English and American legal writing. They present it as a live term because, in their period, it still appeared in sources worth indexing. A modern researcher should understand that its live jurisdiction is Scotland, and its appearance in English-language American legal dictionaries of the nineteenth century reflects the encyclopedic ambitions of those works rather than active American usage.

Jurisdictional Note
Assignation is operative legal vocabulary in Scots law and in legal systems that have drawn from the Scots tradition. In English and American law, assignment is the universal term and assignation appears, if at all, only in historical materials or direct quotation from Scots sources. Researchers working across both traditions in the same project should be precise about which vocabulary belongs to which system.
