Definition
Latin: "as not written." A legal fiction by which a provision, clause, condition, or entire instrument is treated as though it never existed — not merely struck down or declared invalid, but regarded as a nullity from the outset. The document or provision to which the doctrine applies is given no legal effect, as if the offending text had never been placed on paper.
The concept operates differently from simple invalidity or voidability. When a court or legal system treats something as pro non scripto, the instrument or clause is not unwound from a point of challenge forward; it is deemed never to have had legal existence at all. The remainder of the instrument, where severable, typically stands.
The doctrine appears most commonly in civil law and equity contexts — particularly in the treatment of testamentary provisions that violate public policy, illegal conditions attached to gifts or bequests, and clauses in wills or contracts that are void ab initio. A condition attached to a legacy that is impossible, illegal, or contrary to public policy may be struck as pro non scripto, leaving the gift itself intact.

Common Confusion
Pro non scripto should not be confused with void or voidable, though the practical result often overlaps. A void act has no legal effect but may still require a court to confirm its nullity. Pro non scripto goes further as a fiction: the writing is treated as never having occurred, eliminating any procedural or evidentiary consequence that might otherwise attach to a void instrument. It also differs from rescission, which operates prospectively to unwind a legal relationship from the time of rescission forward. Pro non scripto operates retroactively by legal fiction, effacing the writing entirely.

Why It Matters in Research
Researchers encountering pro non scripto in historical sources — particularly equity decisions, Scottish law, and civil law jurisdictions — should understand that the phrase signals a specific analytical move, not just a conclusion of invalidity. Courts invoking this doctrine are making a jurisprudential claim about the ontological status of the text in question: it does not exist in law.
In English chancery practice, the doctrine arose most visibly in the context of illegal or impossible conditions attached to testamentary gifts. When such a condition was struck as pro non scripto, the legacy passed unconditionally rather than failing entirely. This is a critical research trap: a reader who treats the phrase as merely synonymous with "void" will miss the structural argument about severability that the doctrine embeds.
Scottish law sources use the doctrine more broadly, and Burrill's citation to Wilson & Shaw's Reports (7 Wils. & Shaw's R. 523) points toward Scottish appeal practice before the House of Lords, where civil law influence was stronger. Researchers working in Scots law, Louisiana, Quebec, or other mixed jurisdictions will encounter the phrase in contexts where English common law sources may not adequately explain its scope.
In historical American legal materials, the term appears occasionally in equity and probate practice but was never systematically developed in case law. Researchers searching early American reports for pro non scripto will find it primarily in opinions with strong equity or civil law influence — New York, Louisiana, South Carolina, and Maryland are more productive jurisdictions than New England common law courts.
The citation appearing in both Black's editions — "Ambl. 139" — refers to Ambler's Reports, an English chancery reporter covering decisions of Lord Hardwicke. That citation is worth pursuing when researching the early equity foundations of the doctrine.

Historical Dictionary Support
All four source dictionaries agree on the core translation: "as not written; as though it had not been written; as never written." The unanimity is notable and reflects the phrase's status as settled Latin terminology rather than a contested doctrine.
Burrill adds the most substantive information, equating the phrase with "void" while cross-referencing "pro non scriptis" as an alternative form and supplying the Scottish appellate citation. This expansion is useful: it confirms that the doctrine was understood in American legal practice as functionally equivalent to a void declaration, even if technically distinct as a civil law fiction.
Black's first and second editions are identical in substance. Bouvier, characteristically, provides no analysis beyond translation. None of the historical dictionaries address the severability function of the doctrine — its specific operation in saving a gift or bequest by excising an illegal condition — which is arguably its most practically important application in equity. Researchers relying solely on these dictionary entries will understand what the phrase means but not what it does.

Jurisdictional Note
The doctrine has its strongest operational history in civil law and mixed jurisdictions. In pure common law systems, courts more often reach equivalent results through void ab initio analysis without invoking the Latin fiction. Louisiana and Scottish law sources offer the richest development of pro non scripto as a distinct analytical category.
