Definition
A Latin phrase meaning "as of fee." In medieval English land law, ut de feodo describes the character of a seisin — specifically, the quality of a tenant's holding in land as a fee, meaning the holding was owned outright in a heritable freehold estate rather than held temporarily or for a limited term. The phrase appears most often in the technical description of an ancestor's seisin at the time of death: an ancestor who died seised "ut de feodo" held the land as a fee, a condition necessary to support certain real actions and to establish inheritance rights in the heir.
The practical weight of the phrase lies in its connection to the doctrine of seisin. For a writ of entry, mort d'ancestor, or similar real action to lie, it generally had to be shown that the relevant ancestor died seised of the tenement in question — and seised specifically as of fee, not merely as a termor or as a life tenant. The ut de feodo qualifier confirmed that the seisin was of the heritable estate, not some lesser interest.
Core Elements
Ut de feodo carries three interrelated components when used in the context of ancestral seisin:
1. SEISIN: The ancestor must have had actual seisin — possession recognized by law — of the tenement at the time of death. Seisin in law was generally insufficient; seisin in deed was required.
2. FEE QUALITY: The seisin must have been as of fee (ut de feodo), meaning the estate was a freehold of inheritance — a fee simple or fee tail — not a life estate, a term of years, or a mere custody.
3. AT DEATH: The ancestor must have died while seised in this character. Alienation or divestment before death broke the chain of qualifying seisin.
These elements together satisfied the foundation for the heir's real action or inheritance claim.
Why It Matters in Research
Ut de feodo is a navigational term for research in medieval and early modern English land law. Researchers working in Bracton, Britton, Fleta, or the Year Books will encounter the phrase repeatedly in discussions of real actions — particularly mort d'ancestor — and in the broader treatment of seisin doctrine. It signals a technical pleading standard, not a mere description of tenure.
The key research trap is confusing the quality of the seisin (ut de feodo) with the existence of seisin itself. Sources sometimes discuss seisin without specifying its character; the ut de feodo qualifier is what elevates a bare seisin into one sufficient to support inheritance or real action. When reading pleadings or abridgements from the twelfth through sixteenth centuries, the presence or absence of this phrase may determine whether a particular writ or action was available.
The phrase also connects to the demesne doctrine. Burrill's citation to Bracton (fol. 263) and Fleta (lib. 5, c. 25) establishes that every tenement of which an ancestor died seised ut de feodo could be called the heir's "demesne" — a point with consequences for how the heir's right was characterized and what actions were available to recover it. Researchers pursuing the concept of ancient demesne or the writs associated with it should follow this connection carefully.
In the Law Mind corpus, ut de feodo threads through entries on seisin, demesne, mort d'ancestor, and fee, and appears as a prerequisite condition in treatise discussions of the assizes. It is not a standalone doctrine but a technical qualifier embedded in larger structures of real property law.
Historical Dictionary Support
Both editions of Black's define the phrase identically and minimally: "as of fee." This is accurate but gives the researcher no functional context. Burrill's entry is substantially more useful. By quoting Bracton directly and cross-referencing Fleta, Burrill shows that the phrase operates as a legal standard within the law of demesne and seisin — not merely as a translation note. The Bracton passage establishes that ut de feodo seisin at death is the foundation upon which a tenement becomes the heir's demesne, with or without usufruct. This is a meaningful doctrinal point that the Black's entries leave entirely invisible.
None of the historical dictionaries address the procedural dimension — how the ut de feodo standard was pleaded in real actions or tested in litigation. For that, researchers must go to primary sources: Bracton, Fleta, and the relevant Year Book material on mort d'ancestor.
