Definition
An heir of provision is a person who succeeds to property as an heir not by operation of the general rules of intestate succession, but by virtue of an express provision in a deed, settlement, entail, or other instrument. The designation comes from Scots law, where it served as a formal category distinguishing heirs whose right derived from a specific testamentary or inter vivos instrument from heirs whose right derived from blood descent under the law.
In practical terms, the heir of provision took under a tailzie (entail) or similar deed that named or described a line of succession departing from — or supplementing — the default order of heritable succession. The granter of the deed effectively created a succession rather than allowing the law to supply one.

Common Confusion
HEIR OF PROVISION vs. HEIR OF LINE (HEIR AT LAW): The distinction is fundamental in Scots law. An heir of line (or heir at law) succeeds by virtue of blood relationship and the rules of intestate descent. An heir of provision succeeds by virtue of a document. The two categories could overlap — a deed might name the same person who would have succeeded anyway — but the legal basis for the right was entirely different. Researchers working in Scottish estate records must identify which type of heir is being described, because the legal remedies, the burdens attached to the succession, and the competent courts could all differ.
HEIR OF PROVISION vs. LEGATEE: A legatee takes moveable property under a testament. An heir of provision takes heritable property (land) under a deed of provision or entail. Scots law historically maintained a sharp divide between heritable and moveable succession, and conflating these roles in archival or legal sources creates significant interpretive errors.

Why It Matters in Research
This term appears almost exclusively in Scottish legal sources and in English-language treatises discussing Scots property law. Researchers encountering it in English common law sources are almost certainly reading either a Scots law discussion or a direct borrowing from that tradition.
The key research trap is assuming that "heir" in historical Scottish documents carries the same meaning as in English sources. Scots law developed a sophisticated taxonomy of heirs — heir of line, heir of tailzie, heir of provision, heir portioner, heir of conquest, and others — each with distinct legal consequences. Black's treatment is characteristically compressed and can mislead a researcher into thinking the term is self-explanatory.
For corpus researchers working in Scottish estate records, entail documents, or Scots private international law materials, the heir of provision is typically encountered in the context of strict entails (tailzies) created under the Entail Acts, particularly following the Entail Act 1685 (sometimes called the Act of the Scottish Parliament securing tailzies). After the Entails (Scotland) Acts of the nineteenth century progressively dismantled the strict entail system, the practical importance of this category declined. Later materials may reference heirs of provision in the context of unwinding or disentailing estates.
The term also surfaces in Scottish court records — particularly in the Court of Session — where disputes about whether a claimant qualified as heir of provision under a specific deed were litigated. These are distinct from general succession disputes and call for research into the specific deed's terms, the law of tailzie, and the conditions attached.
English-trained researchers should resist mapping this concept onto the English categories of special occupant, remainder, or specific bequest. The Scots heritable succession system operated under different structural logic entirely.

Historical Dictionary Support
Black's Law Dictionary defines the term economically: "One who succeeds as heir by virtue of a particular provision in a deed or instrument." The entry correctly identifies the Scottish provenance and the core distinction — deed-based succession rather than law-based succession — but provides no elaboration on the wider taxonomy of Scots heirs or the historical context of tailzie law in which the term operated.
No other dictionary in the available source set addresses this term. The brevity of the Black's entry reflects the term's narrow jurisdictional scope; it was not a working concept in American or English common law practice and therefore received only passing treatment in general legal dictionaries written primarily for those audiences.
Researchers needing substantive treatment should consult dedicated Scots law sources: Erskine's Institute of the Law of Scotland and Bell's Principles of the Law of Scotland both address heritable succession and the categories of heirs with the depth that general dictionaries do not provide.

Jurisdictional Note
This is a term of Scots law with no direct equivalent in English common law or American law. It may appear in comparative law materials, in Scottish-American estate administration where Scottish heritable property is involved, or in historical legal scholarship addressing the law of entails. Researchers outside the Scottish law context will not encounter this term as an operative legal category.
