Definition
To assign is a verb with three distinct legal applications, all sharing the core idea of directing or transferring something from one place, person, or purpose to another.
1. To transfer property, a right, or an interest. In its most legally significant sense, to assign means to convey to another person one's interest in property, a contract right, a lease, a claim, or other legal entitlement. The act of assignment divests the transferor (assignor) of the interest and vests it in the transferee (assignee). This is the dominant meaning in modern legal usage.
2. To appoint, designate, or allot. Courts and officials assign counsel to defendants, assign judges to cases, and assign duties to officers. Statutes assign jurisdiction. In this sense the word carries administrative and official force — a superior directs a person or resource to a particular role or function.
3. To point out or specify formally. In older pleading practice, a party would assign errors on appeal — that is, identify specifically which legal errors were committed below. This procedural meaning is largely archaic but appears throughout pre-twentieth-century records.

Common Language
Modern common usage (Wiktionary): To designate something for a purpose; to appoint someone to an office; to allot a task; to transfer property or a legal right to another person; to attribute something to a category.
Historical common usage (Webster's 1913): To appoint, allot, or apportion; to fix, specify, or point out authoritarily; to make over to another.
The common and legal definitions overlap substantially, but the legal stakes diverge sharply at the transfer meaning. In ordinary speech, assigning a task or a seat involves no permanent transfer of rights. In law, to assign an interest in property or a contract is a formal legal act with consequences for third parties, creditors, and future owners. A researcher who treats the word loosely in a legal instrument may miss that an assignment — unlike a license or a delegation — typically extinguishes the assignor's interest entirely.

Common Confusion
ASSIGN vs. DELEGATE: Assignment transfers a right; delegation transfers a duty. A party may assign the benefit of a contract but generally cannot assign the burden without the counterparty's consent. Many historical instruments use "assign" loosely to cover both, which can obscure whether a duty, not just a right, was meant to pass.
ASSIGN vs. SUBLET: In landlord-tenant law, an assignment transfers the entire remaining leasehold interest to a new tenant; a sublease transfers only a portion, leaving the original tenant with a reversionary interest. The distinction controls whether the assignee or subtenant stands in direct privity with the landlord. Historical leases frequently blur this line.
ASSIGN (verb) vs. ASSIGN/ASSIGNS (noun): Burrill notes that the noun form — a person to whom rights are transferred — was historically common but is now rare in the singular. The plural "assigns" survives in instruments in the phrase "heirs, executors, administrators, and assigns," a formula that extends the grant to successors of all kinds. Researchers encountering "his assigns" in a deed are reading a noun, not a verb.

Recognized Forms
/SUBTYPES
Assign errors: The procedural act of formally specifying, in a writ of error or appellate pleading, the particular rulings claimed to be legally erroneous. A standard formality in common-law appellate practice before modern notice-pleading reforms.
Assign dower: The act of setting apart and allotting to a widow her specific dower interest in lands of the deceased husband — carving out her share from the general estate.
Assign counsel: The court's act of appointing an attorney to represent a party, typically an indigent criminal defendant. This sense is purely administrative and involves no transfer of property.

Why It Matters in Research
The word "assign" is one of the most semantically loaded verbs in the Law Mind corpus precisely because it does different legal work depending on context. A researcher must determine from context which of the three meanings is operative before interpreting the legal effect of any instrument or ruling.
In transactional and property sources, the transfer meaning dominates. Anti-assignment clauses in contracts, restraints on alienation in leases, and statutory restrictions on assignment (common in insurance, personal services contracts, and government licenses) all turn on whether a particular act qualifies as an "assignment" triggering those restrictions. Historical sources are inconsistent about whether partial transfers or transfers by operation of law count.
In appellate practice sources, "assign errors" appears constantly in pre-twentieth-century reports. Researchers reading old appeals should recognize that failure to assign an error was a jurisdictional or waiver issue — courts regularly declined to consider unassigned errors. This procedural trap has no modern equivalent in most jurisdictions.
The noun form "assigns" in conveyancing instruments deserves particular attention. The phrase "heirs and assigns" was a term of art in fee simple grants; its omission in older instruments could — under strict common-law rules — limit the estate conveyed. Modern recording acts and fee-simple presumption statutes have largely eliminated this trap, but it remains critical when interpreting historical deeds in the corpus.
The assignment-of-income doctrine in tax law (see Tax Encyclopedia entry) adds another research dimension: courts ask not just whether a legal assignment occurred, but whether the economic fruit was earned by the assignor before the assignment, making the assignment ineffective for tax purposes regardless of its legal validity.

Historical Dictionary Support
Bouvier gives three distinct meanings — transfer, appointment, and pointing out — and treats them as parallel, which accurately reflects the word's common-law versatility. His cross-reference to Blackstone (2 Bla. Com. 326 for transfer; 3 Bla. Com. 58 for appointment) provides a reliable foundation, and the reference to Fitzherbert's Natura Brevium for the "assign errors" usage ties that procedural meaning to its common-law writ origins.
Burrill is notable for flagging that the noun form "assign" (meaning assignee) was already becoming archaic by his time, while the plural "assigns" had fossilized in instrument drafting. This is useful calibration: the presence of the singular noun form in a source may indicate an older document or a jurisdiction that preserved older usage longer.
Anderson's entry, as reproduced in the source material, appears to be partially captured and relates primarily to executor and administrator liability rather than to "assign" directly — likely a digitization artifact from an adjacent entry on assets or administration. Researchers should treat the Anderson material for this term with caution and cross-check against Bouvier and Burrill.
None of the historical dictionaries address the assignment-of-income doctrine, anti-assignment clauses as a drafting practice, or the modern statutory presumptions favoring fee-simple construction — all of which are essential to contemporary research and are developed more fully in the encyclopedia entries.

Jurisdictional Note
Most U.S. jurisdictions have abolished the common-law rule requiring "heirs and assigns" language to convey a fee simple, replacing it with a statutory presumption that a conveyance passes the grantor's full interest absent contrary language. Louisiana, as a civil-law jurisdiction, treats assignment of obligations under its own Civil Code framework, which differs structurally from common-law assignment doctrine.
