Definition
Latin: "description of the person." A word or phrase used in a legal document solely to identify or point out the particular individual intended, rather than to limit or qualify the legal character in which that person is meant to act or receive. When a term that might otherwise carry a formal or official meaning is used merely to single out a specific person, courts treat it as a descriptio persone and give it identifying force only — not definitional force.
The doctrine arises most commonly in three contexts:
1. WILLS AND LEGACIES: A word like "heir" or "eldest son," when used in a bequest, may function not as a technical legal designation but simply as a way of pointing to the intended recipient. A legacy "to the eldest son of A" is treated as identifying a specific individual; the phrase describes who is meant, not what legal relationship governs the gift.
2. CRIMINAL PLEADING: In an indictment or information, personal descriptions and additions (such as occupation or residence) attached to a defendant's name are characteristically treated as descriptio persone. If the description is false, the defect is not fatal on its face — it can be challenged only by a plea in abatement, not by demurrer or motion in arrest of judgment.
3. CONTRACTS AND INSTRUMENTS GENERALLY: Where a party is identified by a title, role, or capacity that could be read as limiting the instrument to official dealings only, courts may find that the title was used merely as a descriptio persone — to identify who the party is — and that personal liability or benefit attaches regardless of the formal label.

Common Confusion
Descriptio persone is sometimes confused with a legal designation of capacity or status. The distinction is consequential: when a term operates as a legal designation, it confines rights or obligations to a specific role (e.g., "trustee" limiting liability to trust assets). When the same term operates only as descriptio persone, it identifies the individual without restricting the legal effect of the instrument to that role. Courts determine which interpretation applies from context and the apparent intent of the instrument. The confusion most often surfaces in will construction, where "heir" might be read either as a technical term of art or as a colloquial label for a known individual.

Why It Matters in Research
Researchers encounter this doctrine across three distinct bodies of law that rarely cross-reference one another — wills and succession, criminal pleading, and general contract construction — and the principle operates slightly differently in each.
In will construction research, the doctrine is the mechanism by which courts salvage bequests that use informal or technically imprecise language. A researcher tracing a disputed legacy should look for descriptio persone arguments wherever the testator used relational terms ("my eldest son," "my heir," "my partner") that a strict reading might render ambiguous or void for uncertainty.
In historical criminal pleading materials, the plea in abatement limitation is critical. Before modern procedural codes eliminated or simplified abatement practice, a defendant who failed to raise a false personal description by timely plea in abatement waived the objection entirely. Researchers working with pre-codification criminal records should not assume that a false description in an indictment invalidated the proceeding — it almost certainly did not unless properly and timely challenged.
The doctrine also appears as a tool of interpretation in early contract and conveyancing disputes, where a grantor or party was identified by a title (esquire, trustee, executor) and the question was whether personal or representative capacity was engaged. Burrill's citations to early American and English reporters (Day's Reports, Lord Raymond, Strange) signal that the doctrine was well-settled in both common law traditions by the early nineteenth century.
Because descriptio persone appears under different headings in different sources — sometimes under "addition," "abatement," or "will construction" — a corpus search on the phrase alone will capture most primary uses, but supplementary searches on "addition to a name," "plea in abatement — false description," and "heir as description" will surface cases where the doctrine is applied without the Latin label.

Historical Dictionary Support
All three source dictionaries agree on the core proposition: descriptio persone identifies a person without imposing legal limits based on the descriptive term used. The sources are consistent and mutually reinforcing, though each emphasizes a different application.
Bouvier provides the most practically useful guidance, covering wills (the heir-as-designation scenario), criminal pleading (the plea-in-abatement rule), and legacy construction. His treatment is the most organized and cites Roper on Legacies for the succession context.
Black's second edition provides the clearest doctrinal articulation of what the phrase means structurally — that the word or phrase is used "merely for the purpose of identifying or pointing out the person intended, and not as an intimation that the language...is to apply to him only in the official or technical character which might appear to be indicated by the word." This formulation is the most useful for understanding how courts apply the doctrine in capacity disputes.
Burrill's entry is comparatively thin in the surviving excerpt, offering reporter citations (Day's Reports, Lord Raymond, Strange, Hilliard's Real Property, Selden's Reports) without extended analysis. The citation cluster is nonetheless useful for historical research: it confirms that the doctrine had deep roots in English common law (Ld. Raym. 1437; Stra. 729) and was well recognized in early American courts.
No historical source flags the doctrine's application to contracts as a distinct category, which represents a gap in the historical dictionary coverage relative to later case law development.

Jurisdictional Note
The criminal pleading dimension of descriptio persone — specifically the rule that a false personal description is waivable and may be raised only by plea in abatement — was absorbed differently across American jurisdictions as states modernized their criminal procedure codes in the nineteenth and twentieth centuries. In jurisdictions that abolished or substantially modified the plea in abatement, the procedural rule became moot. The substantive will-construction doctrine remains broadly applicable across common law jurisdictions.
