Definition
A testamentary paper is a written instrument that functions in the nature of a will — that is, a document intended to direct the disposition of a person's property after death — but that either lacks the formal requirements of a valid will or has not yet been admitted to probate. The phrase captures two overlapping ideas: (1) a document that resembles a will in purpose and effect but falls short of the formal definition, and (2) any unprobated instrument that, if recognized by a court, would govern the distribution of the decedent's estate.
The term does not describe a specific, formally defined legal instrument. It is instead a descriptive category used by courts and commentators to identify writings that must be evaluated for testamentary intent — the threshold question being whether the document was intended by the author to operate at death to transfer property.

Common Confusion
TESTAMENTARY PAPER vs. WILL: A will is a formally executed instrument that satisfies statutory requirements and, upon probate, legally transfers property. A testamentary paper may be a will in substance but not yet in legal status — or it may be a will-like document that ultimately fails to qualify. The distinction matters enormously in probate proceedings: courts may be asked to determine whether a letter, memorandum, or informal writing constitutes a testamentary paper entitled to probate consideration. Not every testamentary paper becomes a will; not every informal writing is a testamentary paper.
TESTAMENTARY PAPER vs. CODICIL: A codicil amends or supplements an existing, valid will. A testamentary paper may stand alone with no predicate will, and its legal effect, if any, must be established independently.

Why It Matters in Research
The term's practical importance has declined sharply since the nineteenth century, and understanding that decline is essential to reading historical sources accurately.
Under older common law and early American practice, courts exercised broader equitable discretion to give effect to informal writings expressing testamentary intent — letters, memoranda, and unsigned papers were sometimes admitted to probate if they evidenced the testator's wishes with sufficient clarity. The phrase "testamentary paper" appears frequently in this context in pre-twentieth-century reporters and treatises, where courts debated whether a particular writing had the requisite animus testandi.
Modern statutes of wills changed this landscape considerably. By requiring formal execution — signature, attestation by witnesses, and in some jurisdictions notarization — modern law foreclosed the probate of documents that merely resemble wills. As Bouvier notes directly, these statutes caused the phrase to "lose importance." A researcher encountering "testamentary paper" in a nineteenth-century case or treatise should not assume the same analytical framework governs in a modern jurisdiction.
For corpus researchers, the term signals several things worth tracking:
First, jurisdiction matters historically. American states adopted formal execution requirements at different times and with different rigor. A case from one state in 1870 may reflect a far more permissive approach to informal testamentary writings than a contemporaneous case from another.
Second, the phrase sometimes appears in probate procedure discussions rather than substantive law — specifically in the context of what documents must be lodged with a probate court and what triggers the court's jurisdiction to examine an instrument. Even in modern practice, a court may need to determine whether a document is a "testamentary paper" before it can rule on validity.
Third, researchers working in guardianship law will encounter the related concept of testamentary appointment — a parent's designation of a guardian by will. See estates_145 for the intersection of testamentary instruments and guardianship.

Historical Dictionary Support
Black's Law Dictionary defines testamentary paper as an instrument "in the nature of a will; an unprobated will; a paper writing which is of the character of a will, though not formally such, and which, if allowed as a testament, [would have] the effect of a will upon the devolution and distribution of property." This definition captures the functional understanding: the instrument is evaluated by what it would do if recognized, not merely by what it calls itself.
Bouvier's offers the more analytically useful framing by explicitly noting the effect of modern statutes: "Under modern statutes of wills, which preclude a paper from being admitted to probate at all unless fully and formally a will, the phrase has lost importance." Bouvier attributes this observation to Abbott — a signal that the phrase was already in decline as a working legal category by the time the dictionary was compiled.
The two definitions agree on the core meaning but diverge in emphasis. Black's treats the term descriptively, as a category that courts continue to use. Bouvier's treats it historically, as a once-meaningful category whose practical relevance the formal-will regime has substantially eroded. Both are right in their respective registers. Researchers should weight Bouvier's cautionary note heavily when consulting modern sources.
Neither dictionary provides a worked example of the kinds of writings that have been offered as testamentary papers — letters to family members expressing intended distributions, handwritten memoranda found with a will, or diaries containing dispositive language. Case law in specific jurisdictions is the better source for those illustrations.

Jurisdictional Note
Holographic will statutes in approximately half of American states — which permit wills written entirely in the testator's handwriting without witness attestation — may give legal effect to writings that other jurisdictions would evaluate only as failed testamentary papers. A document that is simply a failed will in a state requiring full attestation may be a valid holographic will in a permissive jurisdiction. The distinction is outcome-determinative and warrants jurisdiction-specific research.
