4.1 Latin Terms in Legal Usage

4.1 Latin Terms in Legal Usage

[!NOTE] NALS PP Exam Blueprint Focus: Part 1 of the PP examination, Advanced Communications & Legal Terminology, closes with a heading NALS calls Advanced Legal Terminology, and that heading has exactly two entries: usage of Latin terms and usage of legal terms. "Usage" is the operative word. A PP item is far more likely to embed a Latin phrase in a factual scenario and ask whether the paralegal applied it correctly than to ask for a dictionary definition.

Legal English inherited its Latin from three distinct sources: the canon law of the medieval church, the Roman civil law tradition, and the Law French of the Norman courts. That layered history is why some Latin in a modern pleading is purely ornamental while other Latin carries operative legal consequence. The paralegal's job is to know which is which.

Family One: Forms of Judicial Action

These terms name a specific procedural vehicle. Using the wrong one names the wrong remedy.

The distinction between the two subpoena forms is a recurring exam target. A paralegal preparing a records custodian deposition needs the duces tecum form; sending a bare testimonial subpoena to a records custodian produces a witness with no documents.

Family Two: Timing, Posture & Capacity

• In limine — "at the threshold." A motion in limine is filed before trial to exclude evidence, so that the jury never hears the prejudicial material. A paralegal who calendars a motion in limine for the week after opening statements has missed the point of the term.
• Ad litem — "for the suit." A guardian ad litem is appointed to represent a minor or incapacitated party for that litigation only, not as a general guardian of the person or estate.
• Nunc pro tunc — "now for then." An order entered later but given retroactive effect, typically to correct a clerical omission in the record. It cannot be used to supply a ruling the court never actually made.
• Pro hac vice — "for this occasion." Admission of an out-of-state attorney to appear in a single case, ordinarily requiring local counsel of record.
• Pro se — "for oneself." A party appearing without counsel. A paralegal must be alert here: correspondence with a pro se opposing party goes directly to the party, and the paralegal must not give that party legal advice.
• Sua sponte — "of its own accord." A court acting on its own motion, without a request from either party.
• Arguendo — "for the sake of argument." Signals a concession made only hypothetically, as in "assuming arguendo that the notice was timely."
• Lis pendens — "pending suit." A recorded notice that title to real property is the subject of litigation, giving constructive notice to subsequent purchasers.

Family Three: Jurisdiction & Party Status

Family Four: Doctrinal Latin with Substantive Consequence

These are the terms that change outcomes, not merely vocabulary.

• Stare decisis — "to stand by things decided." The principle binding a court to precedent within its own hierarchy.
• Res judicata — "a thing adjudicated." A final judgment on the merits bars relitigation of the same claim between the same parties.
• Res ipsa loquitur — "the thing speaks for itself." Permits an inference of negligence from the nature of the accident itself where the instrumentality was in the defendant's exclusive control and the event does not ordinarily occur absent negligence.
• Respondeat superior — "let the master answer." Imposes vicarious liability on an employer for an employee's torts committed within the scope of employment. This is the doctrine under which a law firm answers for a paralegal's negligence.
• Prima facie — "at first sight." A showing sufficient to establish a fact or claim unless rebutted.
• Mens rea / actus reus — the guilty mind and the guilty act; the two components of most criminal offenses.
• Quantum meruit — "as much as he deserved." Recovery of the reasonable value of services where no enforceable contract governs.
• Ultra vires — "beyond the powers." An act outside the scope of a corporation's or agency's lawful authority.
• Ipso facto — "by the fact itself." A consequence following automatically, without further act.
• Per se — "in itself." Conduct that is unlawful without proof of further harm, as in negligence per se.
• Voir dire — historically "to speak the truth"; in modern American usage, the questioning of prospective jurors or of a witness offered as an expert.
• Nolo contendere — "I do not wish to contend." A plea accepting punishment without admitting guilt, and generally not usable as an admission in a later civil suit.
• Per curiam — "by the court." An opinion issued in the name of the court rather than a named author.
• Inter alia — "among other things." Signals that a quoted or listed set is partial.

Citation and Reference Abbreviations

These carry the highest error rate in day-to-day drafting because they look interchangeable and are not.

The e.g. / i.e. confusion is substantive, not stylistic. "The covered vehicles (i.e., sedans and coupes)" defines the category exhaustively and excludes an SUV. "The covered vehicles (e.g., sedans and coupes)" merely illustrates and leaves the SUV arguably inside. Draft one when you mean the other and you have changed the contract.

Formatting Conventions

Latin words and phrases are italicized in legal writing, with one working exception: terms so thoroughly naturalized into English legal vocabulary that they are treated as ordinary English. In practitioner documents that group commonly includes habeas corpus, res judicata, prima facie, de facto, pro se, and amicus curiae. Signals and citation shorthand such as Id., see, cf., and supra follow the citation manual rather than general prose rules. When a document is inconsistent, the safer editorial choice is to italicize, then apply the convention uniformly throughout the filing.
