Definition
A statu liber (plural: statu liberi) is a person in Roman law whose freedom has been conditionally granted by testamentary disposition — that is, a slave freed by will subject to a condition or the passage of a specified time. The term translates roughly as "one whose status is fixed" or "one appointed to liberty." The slave does not become free at the moment the will takes effect but remains in a legally intermediate position: still technically enslaved, yet with a recognized and enforceable expectancy of freedom once the condition is satisfied or the appointed time arrives.
The classic source is Digest 40.7, which addresses the statu liberi in some detail — their capacity to perform acts that might count toward fulfilling conditions, their treatment during the intervening period, and the obligations of the heir who holds them in the interim.

Common Confusion
Statu liber is sometimes loosely equated with a manumitted slave or a freedman (libertus). These are distinct. A libertus has already attained freedom; a statu liber has not yet attained it. The freedom of a statu liber is contingent and prospective. Confusing the two distorts analysis of Roman law texts dealing with the timing of manumission and the rights that attach at different stages of the process.

Why It Matters in Research
This is a term of pure Roman law with no direct common-law counterpart, and it surfaces almost exclusively in one of three research contexts:
1. Roman law and civil law scholarship. Researchers working in Roman private law, particularly on the law of slavery, manumission, succession, and testamentary conditions, will encounter statu liber in primary sources (the Digest, especially Title 40.7) and in civilian commentary. The concept is a building block for understanding conditional obligations and the legal personality of enslaved persons under Roman law.
2. Comparative and historical legal analysis. Scholars examining the treatment of enslaved persons in jurisdictions influenced by Roman or civil law — notably Louisiana, South Carolina under Spanish or French colonial periods, and Latin American legal systems — may encounter the concept where Roman-derived rules about conditional manumission influenced local practice.
3. General legal dictionaries and glossaries. The term appears in Black's and similar reference works primarily as a Latin glossary entry. Researchers using older Anglo-American legal dictionaries should be aware that the entry conveys Roman law doctrine, not common-law doctrine. It has no equivalent function in English equity or common law.
A practical trap: the second edition of Black's as reproduced in the Law Mind corpus appears to contain a transcription or pagination anomaly — the statu liber definition is run together with material from a statistics entry, suggesting a source text where these entries were adjacent and were imperfectly separated. Researchers relying on that edition should verify the entry boundaries.

Historical Dictionary Support
Both editions of Black's define statu liber consistently: a slave made free by will under a condition, with freedom fixed at a certain time or upon a certain event. Both editions correctly point to Digest 40.7 as the foundational source.
What the dictionary entries do not convey is the doctrinal complexity behind the term. The Digest title on statu liberi runs to considerable length and addresses subsidiary questions: whether a statu liber who performs a condition despite an heir's interference is entitled to freedom; what happens if the condition becomes impossible; whether children born to a statu liber after the testator's death are themselves free. None of this doctrinal texture appears in the Black's entries, which function purely as identification glosses rather than substantive explanations. Researchers who need to work with the concept beyond basic identification should go directly to Digest 40.7 and to civilian commentary rather than relying on dictionary coverage.
Wharton's Law Lexicon and similar nineteenth-century legal glossaries cover the term in similar fashion — brief Latin identification, citation to the Digest — reflecting the role such terms played in Anglo-American legal education of the period as demonstrations of Roman law familiarity rather than operative doctrine.

Jurisdictional Note
Statu liber is Roman and civil law doctrine without direct application in common-law jurisdictions. Its closest practical relevance in American legal history is in Louisiana, where Spanish and French civil law influence meant that Roman manumission concepts had some historical purchase. It is not operative doctrine in any current American jurisdiction.
