Definition
Seisina is the Latin (Law Latin) form of seisin — the actual possession of a freehold estate in land. In medieval and early common law, seisina denoted not merely physical occupation of land but the legally recognized condition of holding a freehold in the feudal sense: a formal, visible, and socially acknowledged relationship between a person and the land. To have seisina was to stand as the root of ownership for purposes of feudal tenure, inheritance, and the forms of action available at law.
The term appears most commonly in two maxims and one procedural context:
1. Seisina facit stipitem — "Seisin makes the stock." Under this doctrine, actual seisin of a freehold made the person seised the root or stock from which the blood line of inheritance descended. An heir could only inherit through an ancestor who had been actually seised of the land. This rule had significant consequences: a person who never achieved actual seisin could not serve as the stock of descent, effectively cutting off inheritance through that line.
2. Habere facias seisinam — "That you cause to obtain seisin." A writ of execution by which a court directed the sheriff to deliver actual possession of freehold land to a successful demandant. The words were operative; they triggered the sheriff's authority to physically transfer possession.
3. Seisina as procedural fact. In the real actions of the old common law, proof or allegation of seisin was an essential element of the pleading. Without it, the action could not proceed.
Common Confusion
Seisina and seisin are not different concepts — seisina is simply the Law Latin rendering of the anglicized term seisin. Researchers encountering seisina in writs, pleadings, or Latin maxims should treat it as equivalent to seisin in all substantive respects. The distinction is orthographic and linguistic, not legal. Confusion arises primarily when researchers unfamiliar with Law Latin fail to recognize the connection and treat the two as separate doctrines.
Why It Matters in Research
Seisina appears almost exclusively in Law Latin contexts: formal writs, early common law pleadings, and the maxims preserved in treatises from Bracton through Blackstone. Researchers working with pre-nineteenth-century English land law materials will encounter the term in its Latin form far more often than in anglicized spelling.
The maxim seisina facit stipitem is the most consequential doctrinal use. It was the governing rule of descent in English common law until abrogated by statute — in England by the Inheritance Act 1833 (3 & 4 Will. IV, c. 106), which Anderson's source notation references as "3 a" (a truncated citation to that Act). Researchers working with English inheritance disputes before 1834 must understand this doctrine: the outcome of a case could turn entirely on whether an intermediate ancestor had achieved actual seisin, not merely equitable or constructive title. Equity sources and common law sources may diverge sharply on this point.
For American researchers, the doctrine's application varied. Many American jurisdictions inherited the common law rule of descent through seisin, but statutory reform came at different times in different states, and some never fully adopted the English rule in the first place. When using American treatises or digests from the early republic through the mid-nineteenth century, watch for whether the author is describing English doctrine, a local variant, or a reformed rule.
The writ habere facias seisinam is a procedural artifact. Researchers tracing the execution of judgments in real actions will find this writ in sheriff's returns, court rolls, and pleading records. It is functionally extinct in modern practice but appears regularly in historical property litigation records.
Historical Dictionary Support
Black's Law Dictionary (both the first and second editions) treats seisina as a pure Law Latin entry, doing no more than identifying it as the Latin form of seisin and citing the maxim seisina facit stipitem with references to Blackstone's Commentaries (2 Bl. Comm. 209) and Broom's Legal Maxims. This is a signpost entry, not a substantive definition — both editions direct researchers immediately to the seisin entry for doctrine.
Anderson's Dictionary of Law is more useful here. Anderson provides actual substance: it defines seisina as "actual possession of an estate of freehold," explains the habere facias seisinam writ, unpacks the seisina facit stipitem maxim with the important gloss that "actual seisin formerly made a person the root or stock from which inheritance by blood was derived," and — critically — notes that the rule was discarded by statute. Anderson's entry thus captures both the doctrine's content and its obsolescence in a way Black's does not.
What the historical dictionaries collectively omit: any treatment of the distinction between actual seisin and seisin in law, the feudal mechanics underlying the doctrine's rationale, or the equity-law tensions the rule generated. Researchers who need that depth must go to primary treatise sources, particularly Blackstone's Commentaries Book II and Coke on Littleton.
Jurisdictional Note
The doctrine of seisina facit stipitem was English common law doctrine substantially abolished in England by the Inheritance Act 1833. American jurisdictions varied in their adoption and reform of the rule; researchers should not assume uniform reception. Colonial and early republic cases may apply the doctrine in full; post-reform cases depend on local statute.
