Definition
A servitude obligating the occupants or owners of designated lands to bring their grain to a specific mill for grinding, in exchange for payment of a fixed toll or price known as multure. The obligation ran with the land rather than with the person, binding successive occupiers of the burdened tenement to use the appointed mill. The mill owner or lord held the corresponding benefit, typically as an appurtenant right attached to the mill property.
The doctrine belongs to the broader category of land servitudes and is closely related to the feudal institution of thirlage, under which a lord compelled tenants within a defined territory (the sucken) to grind exclusively at his mill. Astriction to a mill is essentially the formal legal description of that compelled grinding obligation, viewed from the side of the burdened land rather than the dominant mill.
Common Confusion
ASTRICTION TO A MILL vs. THIRLAGE: These terms describe the same feudal milling system from different angles. Thirlage names the overall institution — the lord's right to compel grinding at his mill and the tenant's correlative duty. Astriction to a mill names the servitude as it attaches to specific land. Historical sources sometimes use the terms interchangeably; researchers should not assume a meaningful legal distinction in older texts.
ASTRICTION TO A MILL vs. MULTURE: Multure is not the same as astriction. Multure is the toll or portion of grain paid to the miller as compensation for grinding. Astriction is the obligation to attend a particular mill in the first place. A tenant under astriction owed both duties: attendance at the mill and payment of multure once there.
Core Elements
For the servitude to operate, historical sources required:
1. Burdened land: Specific lands were designated as within the mill's sucken or ambit of compulsion. The obligation attached to those lands.
2. Dominant mill: A particular mill held the benefit of the servitude. The right was tied to that mill's operation and ownership.
3. Grain nexus: The obligation applied to grain grown on the burdened lands or, in some formulations, grain brought within those lands — extending the duty beyond resident production.
4. Multure: A fixed or customary toll was paid to the miller. The rate was often a fraction of the grain ground, set by local custom or grant.
Why It Matters in Research
This term is almost exclusively a Scottish and feudal legal concept. Researchers encountering it in English-language sources will be working with Scottish law, colonial land grants modeled on Scottish practice, or comparative property law scholarship. The term does not appear in mainstream English common law as an operative doctrine.
In the Law Mind corpus, astriction to a mill surfaces most often in historical property surveys, feudal tenure discussions, and Scottish legal history materials. It may appear in records concerning estate administration, mill rights, or the abolition of thirlage — a reform process that unfolded in Scotland over the eighteenth and early nineteenth centuries. Researchers analyzing land burdens or servitudes in pre-reform Scottish materials should treat astriction as a routine encumbrance that would need to be accounted for in any conveyance or estate inventory.
The term is also a useful entry point for understanding the broader feudal dues system. Primary documents may use variant spellings or cognate terms (thirling, sucken, sucken-right, bondage of mill) without explicit cross-reference. Awareness of the concept helps researchers recognize the institution across terminological variation.
Because the doctrine was tied to feudal tenure, its legal force in Scotland was substantially extinguished by the Thirlage Abolition Act of 1799 (39 Geo. III c. 55). Sources predating that legislation treat astriction as an enforceable servitude; post-abolition sources treat it as a historical relic or a compensable right extinguished by statute. Researchers must situate their sources relative to that legislative break to interpret claims and disputes accurately.
Historical Dictionary Support
Both editions of Black's Law Dictionary carry nearly identical definitions, drawing directly on Jacob's Law Dictionary. Both editions define the term as a servitude requiring that grain grown on or brought within certain lands be carried to a specific mill for grinding, with multure paid in exchange. The second edition contains what appears to be a typographical error — "will" in place of "mill" — but the substance is unchanged.
Neither Black's edition provides context about the Scottish origins of the doctrine, the institution of thirlage, or the legislative abolition of the right. The definitions are accurate as far as they go but present the term in isolation from the legal system that gave it meaning. Researchers relying solely on Black's will understand what the servitude required but may not understand when it was enforceable, in what jurisdictions, or how it was extinguished. Jacob's Law Dictionary, cited as the authority in both editions, is the deeper source and reflects an earlier period of practice.
Jurisdictional Note
Astriction to a mill is a doctrine of Scots law with no operative counterpart in English common law. Researchers working in American law will encounter it only in historical or comparative contexts. Its practical legal significance in Scotland ended with the Thirlage Abolition Act of 1799, though compensation claims and residual disputes extended into later decades.
