Definition
A Latin term from old English law meaning ingress or entry. Ingressus most commonly referred to the relief payment made by an heir who had reached full age upon entering, or taking possession of, a feudal fee held from a lord. The payment acknowledged the heir's formal re-entry into tenure following the ancestor's death and restored the tenurial relationship between the new tenant and the lord.
The term functioned both as a descriptor of the physical act of entry onto land and as a label for the legal incident — the monetary relief — that accompanied that entry in the feudal system.

Common Confusion
Ingressus is closely related to, but not synonymous with, relief as a general feudal concept. Relief was the broader category of payment owed to a lord upon inheritance; ingressus was a specific label for that payment when framed in terms of the heir's act of entering the fee. Some historical sources use the terms interchangeably; Rapalje & Lawrence and Blount preserve the distinction most clearly by defining ingressus specifically as the relief paid for entering upon the fee, tying the payment expressly to the entry rather than to the inheritance event alone. Researchers should not assume that every use of "relief" in a feudal context carries the entry-specific connotations that ingressus implies.

Why It Matters in Research
Ingressus appears almost exclusively in sources dealing with feudal land tenure and will rarely be encountered outside of that context. Researchers working with medieval and early modern English land records, plea rolls, or treatises on copyhold and fee tenure should recognize it as a technical payment term nested within the feudal incident of relief, not as a freestanding cause of action or an equivalent of modern entry rights.
Several research traps are worth flagging:
First, the Latin root ingressus — meaning simply "a going in" or "entrance" — is common in classical and ecclesiastical Latin. A researcher encountering ingressus in non-legal or ecclesiastical texts should not assume the feudal payment meaning applies. Context is essential.
Second, the historical dictionaries that define this term are effectively in agreement and draw from the same narrow set of authorities: Cowell's Interpreter and Blount's Law Dictionary. This means the corpus evidence for ingressus is thin and concentrated. Researchers should not expect to find significant doctrinal elaboration in later common law treatises; the term recedes as the feudal incidents it described were abolished or fell into disuse.
Third, because ingressus is tied to entry upon a fee, it may appear in conjunction with related feudal vocabulary — heriot, relief, primer seisin, wardship — and researchers tracing any one of those terms may encounter ingressus as a contextual marker pointing toward the heir's act of assumption of tenure.
For Law Mind corpus researchers, ingressus is most useful as a confirmatory term: its presence in a document signals feudal tenure context, inheritance of a fee, and the lord-tenant relationship at the moment of succession.

Historical Dictionary Support
The historical dictionary sources are in close agreement, with only minor variation in emphasis. Black's Law Dictionary (both the first and second editions) defines ingressus identically as "ingress; entry" with the gloss that the relief paid by an heir was "sometimes so called," citing Cowell. Burrill's Law Dictionary tracks the same definition, adding the Latin derivation from ingredi (to enter) and likewise citing Cowell. Rapalje & Lawrence provides the most precise formulation, drawn from Blount: "the relief which an heir at full age paid to the head lord for entering upon the fee." This formulation is the most legally specific, tying the payment to an heir of full age — distinguishing it from situations involving wardship, where a minor heir's entry was managed differently — and specifying that it ran to the head lord.
None of the historical sources elaborate significantly beyond these short definitions. There is no developed doctrine, no case law, and no statutory framework offered. The entry in each source is vestigial: preserved for completeness in coverage of feudal vocabulary but not treated as a living legal concept even at the time these dictionaries were compiled. Researchers should treat this consensus as reflecting both the genuine narrowness of the term's application and the common dependence of all these sources on Cowell and Blount rather than independent research.

Jurisdictional Note
Ingressus is a term of English feudal law with no direct equivalent in American law. The feudal incidents to which it belonged were substantially abolished in England by the Tenures Abolition Act 1660 and had no formal reception in American common law. Researchers working in American legal sources will not encounter ingressus as an operative legal term.
