Definition
In law, progression refers to the intermediate state of a transaction, proceeding, or matter — that which occurs after commencement but before completion. It denotes acts or stages that belong to the body of a legal transaction, distinguishing them from the initiating act that opened the matter and the concluding act that closes it.
The concept is narrow in its classical legal sense: an act or condition of progression is one that takes place in the course of an ongoing legal matter and derives its character from that ongoing status. It is neither inception nor termination, but the middle ground between them.
Common Language
Modern common usage (Wiktionary): The act of moving from one thing to another; development, increase, or evolution; forward motion through a course or sequence.
Historical common usage (Webster's 1913): The act of moving forward; a proceeding in a course; motion onward; also a regular or proportional advance in numbers (arithmetical or geometrical progression).
The common meaning carries a sense of advancement or improvement — progress toward something. The legal meaning is deliberately neutral and positional. In law, progression does not imply improvement or forward momentum; it simply identifies a transactional state as neither beginning nor end. A researcher encountering the term in historical legal texts should resist reading any directional or developmental significance into it.
Common Confusion
Progression is sometimes loosely conflated with progress in older legal writing, but the two are not equivalent in the classical sources. Progress (as a noun of state) can describe the general course of a proceeding; progression, as used by Plowden and adopted by Black's, identifies a specific intermediate quality — it answers the question of where within a transaction an act sits, not how well that transaction is advancing. Confusion also arises with the term pendency, which describes a proceeding as pending or unresolved from a procedural standpoint. Progression is a more substantive characterization of transactional stage, while pendency is a procedural status with distinct legal consequences (lis pendens being the prime example).
Why It Matters in Research
Researchers working in historical common law sources — particularly Plowden's Commentaries and the early Coke reports — will encounter progression as a technical term of art in transactional and property law analysis. Its significance lies in determining which rules apply to a given act: rules governing commencement, rules governing intermediate acts, and rules governing completion often differ, and classification of an act as being in progression could determine outcome.
In the Law Mind corpus, this term is most likely to surface in:
— Contract administration materials, where identifying the stage of performance (commenced, in progress, or complete) governs obligations, remedies, and notices.
— Construction law contexts, where progress and completion are formal contractual milestones with payment and liability consequences.
— Historical property and conveyancing materials, where the intermediate state of a transaction affects when title passes, when covenants attach, and when conditions are triggered.
The term is largely obsolete as a standalone legal term of art in modern practice, having been absorbed into more specific doctrines (substantial performance, pendency, partial performance). Researchers should treat it primarily as an interpretive tool for reading historical sources rather than as a live doctrine.
Historical Dictionary Support
Black's Law Dictionary (1st and 2nd editions) give identical definitions, both citing Plowden 343. The definition is brief and descriptive: progression is that state of a business which is neither the commencement nor the end, and denotes some act done after the matter has commenced and before it is completed.
Both editions follow the Plowden entry immediately with the Latin maxim Prohibetur ne quis faciat in suo quod nocere possit alieno — a placement that appears to be a typographical artifact of the original dictionary layout rather than a substantive connection to progression. Researchers consulting scanned or transcribed versions of Black's should be aware that the maxim belongs to the following entry (Prohibetur), not to Progression.
Neither edition expands the definition beyond the Plowden citation, and neither edition connects it to contract doctrine, property law, or procedure in any sustained way. The historical sources are thin on this term. Webster's 1913, while not a legal source, provides useful context: the common understanding of progression as forward motion and proportional advance sheds light on why early common law writers chose the term to denote intermediate transactional stages — the matter is in motion, underway, but not yet resolved.
