Definition
Legem habere (Latin: "to have the law") is a common law phrase describing the legal capacity of a witness to give sworn testimony in judicial proceedings. A person who possessed legem habere was competent to testify under oath. Conversely, a person who lacked this capacity — most commonly because of a prior criminal conviction — was legally disqualified from serving as a witness, regardless of their knowledge of relevant facts.
The phrase functioned as a term of legal status rather than a description of any single right or procedural rule. To have legem habere was to stand within the law's protection and recognition as a reliable participant in legal proceedings.
Common Confusion
Legem habere is sometimes confused with related phrases concerning legal capacity more broadly — such as capacity to hold property, bring suit, or enter contracts. In classical and medieval legal writing, "having the law" carried those wider implications. In English common law usage, however, the phrase narrowed to mean specifically testimonial competence, particularly as applied to the disqualification of convicted criminals. Researchers should be alert to this narrower English technical sense when reading historical sources.
Why It Matters in Research
This term is almost exclusively a historical artifact of English common law. Its practical significance was abolished by statute — specifically 6 & 7 Vict. c. 85 (Evidence Act 1843), which removed the automatic disqualification of convicted persons as witnesses. Researchers encountering legem habere in pre-Victorian case records, pleadings, or treatises should understand that it signals a now-defunct regime of testimonial competency in which prior criminal conviction rendered a witness wholly incompetent, not merely impeachable.
The critical research trap: modern evidence law replaced disqualification with impeachment. Under the old regime governed by this phrase, a convicted felon could not testify at all. Under modern evidence rules, a prior conviction may be introduced to impeach credibility, but the witness testifies. A researcher reading pre-1843 English materials must not import modern assumptions about how criminal history affects witness testimony.
For American researchers, the doctrine had uneven reception in colonial and early republic courts. Some American jurisdictions adopted the common law disqualification; others modified or rejected it earlier than England did. Materials from American courts in the 18th and early 19th centuries may use the phrase or invoke the underlying doctrine without using the Latin term itself.
Corpus researchers working with English equity or criminal records before the mid-19th century will encounter challenges to witness competency framed in these terms. The phrase may appear in objections to testimony, in motions to strike, or in the grounds for judgment. Understanding legem habere as a term of witness status — not a procedural motion or cause of action — is essential to correctly interpreting such records.
Historical Dictionary Support
All three historical sources agree precisely on the core meaning: legem habere denotes capacity to give evidence under oath, with the common law disqualification of convicted criminals as its defining application. Black's and Rapalje & Lawrence both cite 6 & 7 Vict. c. 85 as the English statutory endpoint of the doctrine; Bouvier offers only the bare definition, consistent with his general practice of condensed entries.
None of the three sources address the broader Roman or medieval usage of the phrase, where legem habere carried implications extending beyond testimonial competence to fuller civil standing. This gap is significant for researchers working with pre-common law sources or civilian-influenced materials. The dictionaries also do not address American jurisdictional variation, leaving the researcher without guidance on how the doctrine was received or modified in the states.
Rapalje & Lawrence's cross-reference to OATH is the most useful navigational pointer in the historical sources, signaling that the doctrine is embedded in a larger framework of oath-taking capacity and related competency requirements.
Jurisdictional Note
In England, the doctrine was formally ended by 6 & 7 Vict. c. 85 (1843). American jurisdictions varied: some retained the common law disqualification into the mid-to-late 19th century before abolishing it by statute or judicial decision. Researchers working with pre-Civil War American materials should not assume uniform adoption of the English rule.
