Definition
Ex is a Latin preposition and prefix that carries two principal legal meanings, both of which remain in active use across modern legal writing. 1. As a preposition: meaning "from," "out of," "by," or "according to." Used in Latin phrases to identify the source, cause, or basis of a legal relationship, obligation, or proceeding. Ex contractu (arising out of contract), ex delicto (arising out of a wrong), ex parte (from or by one party), ex rel. (on the relation of) — all deploy ex in this prepositional sense. 2. As a prefix: denoting that a person formerly occupied a status, office, or relationship but no longer does. An ex-partner, ex-judge, or ex-spouse is someone who once held that position and has since left it. The prefix signals the absence or termination of a once-existing legal relationship.
Common Language
Modern common usage (Wiktionary): To delete or cross out; to extinguish the life of. In informal modern English, "ex" also functions as a standalone noun for a former romantic partner. Historical common usage (Webster's 1913): Webster's treated ex primarily as a Latin prefix meaning "out of" or "former," consistent with the legal usage of the era. The legal significance of ex runs considerably deeper than its colloquial use. As a prefix in legal Latin phrases, ex does not merely signal "former" — it establishes the doctrinal source or procedural posture of a claim, right, or proceeding. Ex parte, for instance, does not simply mean "one-sided" in ordinary conversation; in law it designates a specific class of proceeding with constitutional and procedural consequences distinct from adversarial litigation. Researchers who encounter ex only in its informal sense will miss its structural role in legal taxonomy.
Recognized Forms
/SUBTYPES Ex appears most consequentially as the first element in a cluster of established Latin legal phrases: Ex parte: A proceeding, order, or application made by or for one party without notice to or participation by the adverse party. Among the most frequently litigated uses of ex in modern law. Ex rel. (ex relatione): "On the relation of." Used in case captions to identify the real party in interest when a government brings an action on behalf of a private individual, or when a private individual uses the government's name to prosecute a claim. Ex contractu: Arising from contract. Historically used to distinguish contract-based actions from tort-based ones. Ex delicto: Arising from a wrong or tort. The counterpart to ex contractu in the classic common law division of civil obligations. Ex post facto: After the fact. Appears most prominently in constitutional law, designating laws that criminalize or increase punishment for conduct that was lawful or less-punishable when it occurred. Ex parte Young: A specific and foundational doctrine — not merely a phrase — holding that a federal court may enjoin a state officer from enforcing an unconstitutional state law without the suit being barred by the Eleventh Amendment. The name is derived from the 1908 Supreme Court case and is treated as a term of art in constitutional litigation.
Why It Matters in Research
The research challenge with ex is dispersion: it is not a single doctrine but a linguistic building block spread across dozens of distinct legal contexts, each with its own body of authority, procedural rules, and historical development. A search for "ex" in isolation will return nothing useful. The researcher must identify which ex-phrase is at issue. The ex parte context deserves particular attention because it generates some of the most practically significant modern litigation — emergency protective orders, trade secret seizure orders, temporary restraining orders — and also some of the sharpest constitutional tensions around due process. The procedural requirements for ex parte relief, notice obligations, and standards for modification vary considerably by court and subject matter. In historical sources, the prepositional ex phrases (ex contractu, ex delicto) were taxonomically central to the organization of civil actions. The distinction between actions ex contractu and ex delicto shaped pleading rules, limitations periods, and available remedies under the old forms of action. Modern researchers tracing common law principles into current doctrine need to recognize these phrases as signposts of that earlier system. The ex rel. form in case captions is a frequent source of confusion in database searches. Cases captioned "State ex rel. Smith v. Jones" will not surface in a name search for "Smith v. Jones." Researchers working with older reporters or less sophisticated search tools should be alert to this.
Historical Dictionary Support
Black's Law Dictionary (both editions) and Burrill's Law Dictionary are in full agreement on the core meaning: ex as a Latin preposition meaning "from," "out of," or "according to," and as a prefix denoting cessation or former status. Burrill illustrates the prepositional use with examples — ex facto, ex contractu, ex mero motu — that reflect the phrase-based role ex played in the classical common law vocabulary. Anderson's source material as captured here does not engage directly with ex and is not useful for this entry. Neither Black's nor Burrill attempts a comprehensive treatment of ex as a standalone entry, which reflects the appropriate approach: the real content lives in the individual Latin phrases. Historical dictionaries address those phrases separately, and the researcher should consult entries for ex parte, ex post facto, and ex rel. in those sources directly. What historical dictionaries collectively miss is the modern procedural elaboration of ex parte doctrine — the due process framework, the standards governing emergency ex parte relief, and the Ex parte Young line of constitutional litigation. Those developments are entirely post-historical-dictionary and must be traced through modern treatises and case law.
Jurisdictional Note
Ex parte procedure varies significantly by jurisdiction and by court. Federal courts operate under Rule 65 of the Federal Rules of Civil Procedure for emergency injunctive relief; state courts apply their own analogues, and the threshold showing required for ex parte orders differs across systems. Ex parte Young doctrine is federal constitutional law and applies uniformly in federal courts, but its boundaries — what counts as prospective relief, which officers may be sued — are actively litigated and not uniformly settled.

1. A Latin preposition meaning from, out of, by, on, on account of, or ac- cording to. 2. A prefix, denoting removal or cessation. Prefixed to the name of an office, relation, status, etc., it denotes that the person spoken of once occupied that office or relation, but does so no longer, or that he is now out of it. Thus, ex-mayor, ex-partner, ex-judge. 3. A prefix which is equivalent to "with- out," "reserving," or "excepting." In this use, probably an abbreviation of "except." Thus, ex-interest, ex-coupons. "A sale of bonds 'ex. July coupons' means a sale reserving the coupons; that is, a sale in which the seller receives, in addition to the purchase price, the benefit of the coupons, which benefit he may realize either by detaching them or receiving from the buyer an equivalent consideration." 94 N. Y. 445.

before investigated, or only adds other circumstances of the same general character. See TRIAL, New. Competent evidence. That which the nature of the fact to be proved requires as the appropriate proof in the particular case: as, the production of a writing where its contents are the subject of inquiry; that is, the best evidence.2 Incompetent evidence. Inappropriate, improper evidence. Satisfactory or sufficient evidence. That amount of proof which ordinarily satisfies an unprejudicial mind, beyond reasonable doubt.3 The circumstances which will amount to this degree of proof can never be previously defined; the only test of which they are susceptible is, their sufficiency to satisfy the mind and conscience of a common man, and so convince him that he would venture to act upon that conviction in matters of the highest importance to his own interests. Questions respecting the competency and admissibility of evidence are entirely distinct from those which respect its sufficiency or effect. The former are conclusively within the province of the court; the latter belong exclusively to the jury. Minor terms descriptive of species of evidence: affirmative as opposed to negative evidence; adminicular or ancillary evidence; corroborative evidence; extrinsic as opposed to intrinsic evidence; inculpatory as opposed to exculpatory evidence; newly or after-discovered evidence; rebutting evidence; state's evidence by an accomplice; substitutionary evidence, qq. v. The object of evidence being to prove the point in issue, fundamental rules regulating its production are: 1. The evidence must correspond with the allegations, and be confined to the point in issue. 2. It is sufficient if the substance of the issue be proved. 3. The burden of proving a proposition or issue rests upon the party holding the affirmative. 4. The best evidence of which the case is susceptible must be produced. The general rules of evidence are the same in civil and criminal cases.. The mode of conducting trials, the order of introducing evidence, and the time when it shall be introduced, belong largely to the practice of the court where the fact is tried." 1 Waller v. Graves, 20 Conn. 310-11 (1850), cases, Church, C. J. See also 2 Ark. 353; 42 Conn. 519; 27 Ga. 464; 28 Me. 383; 34 N. J. L. 156; 7 Barb. 278. 2 [1 Greenl. Ev. §§ 2, 32; 107 U. S. 332. #1 Greenl.

The rules of practice in jury trials are necessarily somewhat flexible as to the order of proof, the number of witnesses, and the time, manner, and extent of the cross-examination. In ordinary cases the plaintiff begins and introduces all of his substantive evidence before the defendant opens his defense; so, the defendant introduces all his substantive evidence before the plaintiff rebuts. But the judge, in the exer cise of a sound discretion, may relax either rule.1 The order of admissibility is regulated by the court. The Federal courts, in civil cases at common law, observe as rules of decision the rules of evidence of the State in which they sit, except when otherwise provided by the Constitution or an act of Congress.2 A party who objects or excepts to evidence must state his reasons therefor.3 See further ADMISSION, 2; ANSWER, 3; BOOK; CHARACTER; CHARGE, 2 (2, c); COMPROMISE; CRIME; DECLARATION, 1; DEED; DEMURRER; DEPOSITION; DOCUMENT; DOUBT; ESTOPPEL; EXAMINATION, 9; EXCEPTION, 4; FACT; HANDWRITING; INSPECTION, 2; INSANITY; LAW; LETTER, 3; NONSUIT; NOTICE, 1, Judicial; OFFER, 2; OPINION, 1; PRACTICE; PROCEDURE; REBUT; RECORD; RES, Gestæ; SCINTILLA; STENOGRAPHER; WEIGHT, 2; 1.

N. B. 129, F. ( 575 ) ion of Chase, J. 3 Dallas' R. 386. This misapprehension and error have arisen, in part, from the narrow sense given to the word facto, (confining it to the acts of individuals,) but principally from the common mode of writing the whole phrase, which presents post as a distinct word, thereby not only leading to an ungrammatical connection of its meaning with that of facto, (in the expressions "after a deed," "after the fact," but entirely destroying the sense and force of the word ex, which, in the ordinary translations, is quite disregarded. Strictly, post should be connected with facto, either as one entire word, (postfacto,) in which form it usually occurs in the civil law, and frequently in Bracton, or as a double word, (post-facto,) the latter form having the express authority of Aulus Gellius, who uses both post-facta and antefacta in a passage which will be referred to under Ex post facto law. This mode of writing the phrase dissipates at once all the grammatical difficulty hitherto supposed to attend the use of post in immediate juxtaposition with ex; (both words being commonly treated as prepositions, although post is in fact an adverb, with the sense of afterwards). Ex post-facto is thus most distinctly contrasted with its correlative ab initio; the meaning of ex is the one phrase being at once seen to correspond with that of ab in the other. See Postfactum. It may be added that the whole phrase ex postfacto is frequently used in old English law, as synonymous with postea, (afterwards,) or post tempus, (after a time). Bract. fol. 213. Fleta, lib. 3, c. 3, §§ 5, 7. Id. lib. 4, c. 26, § 4.

Noct. Att. lib. xvii. c. 7. In other words, the question was, whether this was an ex post-facto law or not. The phrase "in ante-facta," (upon acts or actions done before,) in this passage, expresses the peculiar operation of such a law more distinctly, perhaps, than ex post facto itself, and is almost literally translated in the best modern definitions. See supra. The words ante-facta and postfacta, as contrasted in the same passage, both obviously refer exclusively to the acts of individuals; but in the phrase ex postfacto, the post-factum (after-act or post-act) is the act of the legislature itself in passing the law; the ante-factum being the act of the individual upon which the law is made to operate retrospectively. This distinction is noticed by Mr. Justice Chase, in the case already referred to. 3 Dallas' R. L. Lat. From writings formerly seen.
