Definition
A Law French adjective meaning "next" or "nearest." Prochein functions almost exclusively as a prefix element in compound legal terms rather than as a standalone word. It appears most prominently in:
1. Prochein ami (also prochein amy): Literally "next friend." The person who brings or maintains a lawsuit on behalf of someone legally incapable of suing in their own name — most commonly a minor or a person under legal disability. The prochein ami is not a guardian and holds no formal office; the role is procedural, permitting access to the courts for those who would otherwise be barred. The prochein ami appears as the nominal plaintiff but acts in a representative capacity.
2. Prochein avoidance: The next vacancy. Used in ecclesiastical law and property law to describe a right to appoint to the next available benefice or position when the current one becomes vacant.
3. Prochein cousin: Nearest cousin; used in older property and inheritance contexts to identify the closest collateral relation.
Common Language
Modern common usage (Wiktionary): "Next; nearest."
Historical common usage (Webster's 1913): "Next; nearest. Prochein ami or amy (Law), the next friend."
The common meaning and the legal meaning are not in conflict — "next" and "nearest" translate directly. The gap worth noting is that in ordinary usage the word is obsolete English, essentially unknown outside legal contexts. A modern researcher encountering prochein in a historical document should not expect plain-English dictionaries to illuminate the legal significance of the compound terms it forms.
Common Confusion
Prochein ami is sometimes confused with guardian ad litem. The distinction matters for research: a guardian ad litem is appointed by the court and exercises broader authority over the litigation and sometimes the person; a prochein ami is typically a volunteer who steps forward and whose role is more limited and less formally supervised. Historical sources use both terms, and the procedural rules governing each have evolved differently across jurisdictions and time periods. Researchers working in equity courts versus common law courts will find the terms used inconsistently in older materials.
Why It Matters in Research
Prochein is a term of the old law that survives into modern practice almost entirely through prochein ami, which itself has largely been replaced in American jurisdiction by "next friend" in statutes and court rules. When working in the Law Mind corpus, researchers should be alert to the following:
Temporal shift in usage: The word itself is most dense in pre-nineteenth-century common law materials. By the late nineteenth and early twentieth centuries, English-language equivalents begin displacing it in American sources, though prochein ami persists in judicial opinions well into the twentieth century.
Compound-term searching: Prochein almost never appears alone in a legally operative sense. Corpus searches should be structured around the compound forms — prochein ami, prochein avoidance — rather than the root word.
Equity versus common law distinction: The procedural mechanics of prochein ami developed differently in equity and at common law. Sources from equity courts may describe the role differently than common law pleading manuals. This matters when researching the history of representative litigation and access to courts for minors.
Connection to next-friend doctrine: Modern American federal and state procedural rules (such as Federal Rule of Civil Procedure 17(c)) codify the "next friend" concept without using the Law French term. Researchers tracing the lineage of these rules back through historical sources will need to recognize prochein ami as the antecedent form.
Ecclesiastical law context: Prochein avoidance appears primarily in English ecclesiastical and real property materials. It is rare in American sources and almost absent from post-colonial American law. Researchers should not expect to find it in American corpus materials except in treatises discussing English law.
Historical Dictionary Support
All three source dictionaries agree on the core definition: prochein means "next" or "nearest" and derives from Law French. Black's (both editions) and Anderson's are consistent on this point, and Webster's 1913 confirms the common meaning tracks the legal one.
Black's (2nd ed.) provides the most substantive treatment, offering a working definition of prochein ami that captures its procedural function: the next friend who appears as plaintiff for an infant who cannot sue in their own name. The note that the prochein ami is distinct from a guardian is implicit in Black's formulation ("some friend not being his guardian") — a distinction that the first edition states more plainly.
Anderson's cross-reference to AMI is useful; researchers consulting Anderson's for the compound term should follow that cross-reference for fuller treatment.
What the historical dictionaries do not address: none of the source dictionaries discuss the declining use of the Law French form in American practice, the procedural rules governing appointment or accountability of a prochein ami, or the relationship between this role and later codified next-friend provisions. These are gaps that corpus researchers will need to fill through treatises and procedural rules rather than the dictionaries themselves.
Co. Litt. 10, cited in both Black's editions, is Coke on Littleton — a foundational English common law source confirming how deep into the tradition this terminology runs.
Jurisdictional Note
The prochein ami concept is rooted in English common law and was transplanted to American jurisdictions through colonial practice and early procedural codes. American states have largely replaced the term with "next friend" in their rules of civil procedure, but the underlying doctrine is preserved. English practice retains somewhat different terminology and procedures. Researchers working in Louisiana materials should note the civil law background may produce different vocabulary for the same functional concept.
