Definition
A maintainor is a person who unlawfully assists or supports a party in litigation in which the maintainor has no legitimate interest, whether by furnishing money, securing allies, or otherwise advancing one side of a dispute to which the maintainor is a stranger. The term is the agent noun of maintenance: a maintainor is simply one who commits the offense of maintenance. The assistance need not be financial; procuring witnesses, rallying support, or otherwise intermeddling in another's lawsuit may qualify.
Common Language
Modern common usage (Wiktionary): "One who, not being an interested party, maintains a cause depending between others, by furnishing money, etc., to either party."
Historical common usage (Webster's 1913): "One who, not being interested, maintains a cause depending between others, by furnishing money, etc., to either party. Bouvier. Wharton."
The common definitions track the legal definition closely, which is unsurprising given that maintainor is a term of art with no meaningful life outside legal contexts. The slight gap worth noting is this: both Wiktionary and Webster's frame the definition around the neutral act of "maintaining a cause," without signaling that the conduct is wrongful. The legal definition carries an embedded criminal charge — a maintainor is not merely a helper but an offender.
Common Confusion
MAINTAINOR and CHAMPERTY: Champerty is a subspecies of maintenance in which the intermeddling stranger bargains for a share of the proceeds of the litigation. A maintainor may act from meddlesomeness, spite, or general interference without any profit motive. Every champertor is a maintainor, but not every maintainor is a champertor. Researchers encountering historical indictments should distinguish the two, as champerty carried distinct pleading requirements.
MAINTAINOR and BARRATOR: A barrator habitually stirs up quarrels and litigation generally, whereas a maintainor intervenes in a specific pending suit. The offenses could overlap — a barrator who then funded one party's lawsuit would also be a maintainor — but they are conceptually and historically distinct.
Why It Matters in Research
This term is almost exclusively a creature of historical and common-law criminal practice. Researchers working in early American or English legal records will encounter it most often in indictments and criminal pleadings from the eighteenth and nineteenth centuries, where maintenance, champerty, and barratry were treated as criminal offenses and sometimes as common-law torts. By the mid-twentieth century, criminal prosecution for maintenance had largely disappeared in most American jurisdictions, and the term maintainor fell with it.
The principal research trap is anachronism. Modern readers encountering maintainor in a historical source may underestimate its gravity; in its active period it described a criminal defendant, not merely a generous bystander. Conversely, researchers analyzing modern third-party litigation funding must be careful not to project the historical concept of maintainor wholesale onto contemporary arrangements. Many jurisdictions have reformed or abolished the common-law offenses of maintenance and champerty, and modern litigation funding operates under a substantially different legal framework.
When tracing the concept through the Law Mind corpus, follow the thread from MAINTAINOR to MAINTENANCE (the offense) and from there to CHAMPERTY. Cases and treatises addressing barratry often appear in the same sections of historical practice guides, making BARRATOR a useful neighboring search term. Because these offenses were creatures of common law, equity courts also occasionally addressed them in injunction proceedings, meaning chancery materials are relevant to a full search.
Jurisdictional variation matters here: some states abolished maintenance and champerty by statute in the nineteenth century, while others retained them into the twentieth. A maintainor in one jurisdiction might face criminal indictment while the identical conduct in another would be legally unremarkable. Historical sources do not always flag this variation clearly.
Historical Dictionary Support
Both editions of Black's Law Dictionary define maintainor identically in substance, quoting the same Blount formulation: one who "maintains or seconds a cause depending in suit between others, either by disbursing money or making friends for either party towards his help." The reliance on Blount in both editions signals that this definition was borrowed from early English legal lexicography and carried forward without significant doctrinal updating. Neither edition reflects the later erosion of maintenance as an actionable or indictable offense.
Webster's 1913 and Wiktionary both cite Bouvier and Wharton, two of the most authoritative nineteenth-century American legal reference works, confirming that the concept was stable across legal and general dictionaries for most of the nineteenth century. The convergence of Black's, Bouvier, and Wharton on essentially the same formulation suggests the definition was settled during the period when the offense was actively prosecuted; subsequent legal dictionaries have largely preserved it as a historical artifact.
What the historical dictionaries miss: none of them address the decline of the offense, the emergence of reform-era statutes abolishing criminal maintenance, or the doctrinal questions raised by modern contingency fee arrangements and third-party litigation funding that have revived scholarly interest in the underlying concepts.
Jurisdictional Note
Maintenance and champerty were abolished as criminal offenses in England by the Criminal Law Act 1967. In the United States, the status of maintenance as a crime or tort varies by state; some jurisdictions have abolished both by statute, others retain vestiges of the common law. The term maintainor as an operative legal category is unlikely to appear in modern American criminal practice but remains relevant to historical legal research and to academic treatment of litigation finance.
