Definition
In law, MAINTAINED carries two distinct operative senses depending on context:
1. Pleading (criminal). A term of art in indictments for the offense of maintenance — the unlawful intermeddling in another party's litigation. In this technical sense, "maintained" is the precise word required to charge the offense. It cannot be replaced by a synonym without risking a defective pleading. The word does the work of directly tracking the legal definition of the underlying offense.
2. General legal usage. More broadly, "maintained" describes an ongoing act of upholding, preserving, or continuing something — a condition, a structure, a right, a secret, or a legal position. Courts use the term in this sense across a wide range of substantive areas: property law (maintaining a nuisance), civil procedure (maintaining an action), intellectual property (maintaining trade secret protection), and contract disputes (maintaining a condition or warranty).

Common Language
Modern common usage (Wiktionary): showing maintenance or attention.
Historical common usage (Webster's 1913): To hold or keep in any particular state or condition; to support; to sustain; to uphold; to keep up; not to suffer to fail or decline.
The everyday sense of "maintained" — keeping something in working order or continued condition — bleeds naturally into legal usage and is often close enough to cause no confusion. The gap opens sharply, however, in the pleading context: in an indictment for maintenance, "maintained" is not merely descriptive but is a required term of art. Substituting a functional equivalent (such as "supported" or "assisted") historically rendered the indictment defective. Researchers reading historical criminal pleadings should treat the word as a technical signal, not ordinary description.

Common Confusion
Do not conflate the pleading-specific meaning of MAINTAINED with its ordinary descriptive use in legal instruments. A lease requiring that premises be "maintained in good repair" and an indictment alleging that the defendant "maintained" another's suit are using the word in entirely different registers. The first is descriptive; the second is definitional. Conflating them can cause researchers to underweight the technical significance of the term when it appears in criminal pleading contexts.
Similarly, MAINTENANCE (the underlying offense) and MAINTAINED (the pleading word charging that offense) are related but not interchangeable. Maintenance describes the offense; maintained is the operative verb required to invoke it.

Why It Matters in Research
The dual nature of this term creates real navigational challenges in the Law Mind corpus.
In historical criminal pleading materials, "maintained" is a signal word. Its presence in an indictment or information tells the researcher that the document is charging maintenance — the offense of officious intermeddling in litigation. If you are searching historical criminal records for maintenance prosecutions, this is the word to target, not synonyms.
In modern materials, "maintained" appears constantly in a non-technical, descriptive sense across property, IP, contract, and civil procedure sources. Trade secret doctrine in particular turns on whether reasonable measures were "maintained" to preserve secrecy — a usage with real legal consequence but no connection to the criminal pleading tradition.
Corpus researchers should be alert to the chronological and doctrinal context before assuming which sense applies. Pre-20th century criminal pleading documents: look for the technical meaning. Modern civil and IP materials: the word is doing ordinary descriptive-legal work, but may still carry significant operative weight (as in the trade secret context).
The Black's Law Dictionary entries across editions focus exclusively on the pleading sense, which reflects the historical importance of precise criminal pleading language. This narrow treatment means historical dictionaries are incomplete guides for researchers encountering the term in modern civil, property, or IP contexts.

Historical Dictionary Support
Both the first and second editions of Black's Law Dictionary provide identical, terse entries: "In pleading. A technical word indispensable in an indictment for maintenance." The single citation to 1 Wils. 325 (Wilson's King's Bench Reports) anchors this to English common law pleading practice. The definition has not evolved between editions, suggesting the editors treated this as settled rather than contested doctrine.
The historical dictionaries are silent on the broader modern uses of "maintained" — an expected limitation given their focus on technical pleading vocabulary. Researchers relying solely on Black's for this term will find guidance on the criminal pleading context but nothing on the term's role in trade secret, property, nuisance, or civil procedure doctrine. The historical record is accurate as far as it goes; it simply does not go far enough for modern research.
