Definition
Blank bonds were a form of Scots law debt instrument in which the creditor's name was deliberately left unfilled at the time of execution. The bond passed by mere physical delivery, and whoever held the instrument — the bearer — was entitled to insert their own name and then sue for payment as if they had been the original named creditor. In practical effect, blank bonds functioned as negotiable bearer obligations, allowing debt claims to circulate informally outside the formal mechanisms of assignment then available under Scots law.
The instrument is obsolete. The Scottish Parliament declared blank bonds void by Act 1696, c. 25, ending their legal recognition. They have no modern counterpart in either Scots or common law jurisdictions, though bearer instruments in other forms — bearer bonds, bearer notes — share the same essential characteristic of conferring rights on the holder by possession rather than by named title.

Common Confusion
BLANK BONDS vs. BEARER BONDS: The functional similarity between blank bonds and modern bearer bonds can mislead researchers into treating them as equivalent instruments. They are not. Bearer bonds are fully executed instruments payable to whoever holds them, with no blank to be filled in; the bearer character is built into the instrument's terms at issuance. A blank bond, by contrast, was an incomplete instrument — the creditor line was left deliberately empty, and the bearer filled in their own name before or upon enforcement. The blank bond was a workaround specific to Scots law; the bearer bond is a formally constituted instrument with distinct legal history.
BLANK BONDS vs. BLANK ENDORSEMENT: In modern commercial paper law, a blank endorsement means an endorsement without specifying a particular endorsee, making the instrument payable to bearer. This is a different concept — blank endorsement operates on an otherwise complete instrument, while a blank bond was incomplete at the point of the primary obligation itself.

Why It Matters in Research
Researchers encounter blank bonds almost exclusively in one of three contexts: historical Scots law materials predating 1696, commentary on the Act 1696 c. 25 itself, or broad histories of negotiable instruments and bearer obligations.
The primary trap is anachronism. Sources discussing "blank bonds" before 1696 treat them as valid, even commonplace, instruments. Sources after 1696 treat them as a voided category. If a historical source does not date its discussion, assume the pre-abolition treatment unless evidence suggests otherwise.
The Act 1696 c. 25 is part of a cluster of late-seventeenth-century Scottish statutes directed at fraudulent or evasive financial practices, passed in a period of significant reform to Scots private law. Researchers working on the history of negotiable instruments, the history of Scots commercial law, or the emergence of formal assignment doctrine in Scotland will find blank bonds relevant as evidence of what the law was trying to suppress — informal circulation of debt obligations outside regulated channels.
In the Law Mind corpus, blank bonds are unlikely to appear outside historical and comparative materials. Do not expect to find them in modern contract, commercial, or surety bond discussions. The encyclopedia entries on performance bonds and surety bonds (contracts_168, insurance_69) are structurally unrelated; they are flagged here only for researchers who arrived at this entry while researching bond instruments generally and need orientation to the modern materials.
One further note: because Black's Law Dictionary is the primary source carrying this term into English-language legal reference works, researchers relying on American or English legal dictionaries may find the entry sparse or absent in sources other than Black's. Scottish legal dictionaries and institutional writers (Stair, Erskine, Bell) are the appropriate primary shelf sources for fuller treatment.

Historical Dictionary Support
Black's Law Dictionary provides the only entry among the source dictionaries and gives a compact, accurate account: blank bonds were Scotch securities with the creditor's name left blank, passing by delivery, with the bearer free to insert their name and sue — declared void by Act 1696, c. 25. This is functionally complete for most research purposes.
What Black's does not provide is legal or social context: why these instruments existed, what commercial need they served, or why the 1696 Act targeted them specifically. The answer lies in Scots law's historically restrictive approach to the assignation of obligations. Because formal assignation of a debt required notice to the debtor and created procedural complexity, blank bonds offered a shortcut — a debt could effectively be transferred by handing over the bond, with the new holder simply filling in their name. The 1696 legislation was part of broader efforts to close off informal avoidance of creditor-debtor protections and to regularize the transfer of obligations through proper legal channels.
No meaningfully divergent historical dictionary definitions have been identified. The term is narrow, jurisdiction-specific, and historically bounded, leaving little room for the interpretive variation that characterizes more contested legal terms.

Jurisdictional Note
Blank bonds are exclusively a Scots law concept. They have no recognized equivalent in English common law, American law, or other common law jurisdictions. Researchers outside the Scots law tradition who encounter the term in historical comparative sources should treat it as a jurisdiction-specific instrument without attempting to map it onto modern bond or negotiable instrument categories from other systems.
