Definition
Per universitatem (Latin: "by the whole" or "by an entirety") is a civil law term describing the acquisition of an entire estate or aggregate body of property through a single act or legal event, as opposed to the acquisition of individual items one by one. When property passes per universitatem, it transfers as an undivided whole — all rights, obligations, and assets comprising the estate move together in a single operation of law.
The concept captures a fundamental distinction in property transmission: some acquisitions are singular and specific (one thing at a time), while others sweep in an entire juridical mass. Inheritance of a deceased's entire estate is the paradigm case. The heir does not acquire each asset through a separate transaction; the estate descends as a unit.

Common Confusion
Per universitatem is easily confused with per stirpes and per capita, which are also Latin inheritance terms appearing in the same documentary contexts. Those terms govern how shares are divided among multiple heirs. Per universitatem, by contrast, describes the mode of acquisition — the wholesale transfer of an entire estate to a successor — not the apportionment of shares. A researcher encountering any of these terms in a will, probate record, or civil law treatise should pause to confirm which concept is actually at work.

Why It Matters in Research
This term surfaces almost exclusively in civil law contexts — Louisiana, Quebec, historical Spanish and French colonial materials, ecclesiastical law sources, and Roman law scholarship. Researchers working in common law archives are unlikely to encounter it except in comparative law discussions or academic treatises.
The practical trap is terminological: common law sources discussing universal succession or the transmission of an entire estate will rarely use this phrase. They may speak of "universal succession," "entire estates," or "the heir as universal successor" without invoking the Latin. Conversely, civil law sources may use per universitatem as a term of art where a common law researcher might not recognize it as a technical category at all.
For corpus researchers, the term signals that a document is drawing on Roman or civilian inheritance doctrine. Its presence is a reliable marker for civil law influence, which has implications for which secondary sources and commentaries will be most useful for interpretation.
The distinction between per universitatem acquisition and the acquisition of singular things (res singulae) also carries analytical weight in contexts involving debts and liabilities: when an estate passes as a whole, the successor traditionally steps into the shoes of the decedent with respect to obligations as well as assets. This is a meaningful distinction in historical probate disputes and in comparative law analysis.

Historical Dictionary Support
Black's Law Dictionary (2nd Ed., Supplemental) provides the only dictionary source here, and its entry is compact but precise: "By an aggregate or whole; as an entirety. The term described the acquisition of an entire estate by one act or fact, as distinguished from the acquisition of single or detached things." This definition accurately captures the civilian concept.
Historical legal dictionaries in the common law tradition largely pass over this term, which reflects its essentially civilian character. Researchers relying solely on common law lexicons would find no entry at all. The absence is informative: the concept has a home in Justinian's Institutes and the Digest, in Pothier's treatises on obligations and succession, and in the civilian commentators — not in Coke or Blackstone.
What historical dictionaries do not address is the procedural and doctrinal consequence of the distinction: in Roman and civil law, the universal successor (heres) was liable for the decedent's debts without limit, a consequence flowing directly from the per universitatem character of the acquisition. That liability dimension is absent from the brief Black's entry and must be drawn from civilian primary sources.

Jurisdictional Note
The term is operative doctrine only in jurisdictions with civil law foundations. Louisiana remains the primary American jurisdiction where per universitatem concepts retain direct relevance in succession law. In common law jurisdictions, universal succession concepts exist but are expressed in different vocabulary and with different structural rules.
