Definition
The condition of dying with a valid will in place. A person who dies having executed a legally sufficient testament dies in a state of testagy. The term exists in direct opposition to intestacy, which describes death without a valid will.

Common Confusion
TESTAGY vs. INTESTACY: These terms define opposite conditions at death. Testagy means a valid will governs disposition of the estate; intestacy means no valid will exists, and the estate passes under the jurisdiction's statutory default scheme. Researchers should note that partial testagy is possible — a will may dispose of some property while other property passes by intestate succession if the will's coverage is incomplete or if specific assets fall outside its reach.
TESTAGY vs. TESTACY: These are variant spellings of the same concept. "Testacy" is the more commonly encountered form in American legal writing and later editions of legal dictionaries. When searching historical sources, check both spellings.

Why It Matters in Research
Testagy is a low-frequency term that researchers are more likely to encounter in older legal dictionaries, treatises on estate administration, and probate court opinions than in modern statutory text or contemporary case law. Modern practice overwhelmingly favors the noun "testacy" or the adjectival construction "testate" (as in "testate succession" or "testate estate"). Searching historical corpus materials for "testagy" without also running parallel searches for "testacy," "testate death," and "dying testate" will produce incomplete results.
The practical significance of the testagy/intestacy distinction runs throughout probate and estate law: it governs which legal framework applies to administration, who has standing to open an estate, what priority rules apply to creditors, and how the decedent's property ultimately passes. Any research touching on estate administration, will contests, or succession planning will encounter the underlying concept even when this specific term does not appear.
Because "testagy" appears primarily in the foundational Black's editions and early American treatises, its absence from a source does not mean the concept is absent — look for the synonymous forms noted above.

Historical Dictionary Support
Black's Law Dictionary (2nd Ed.) provides the only historical dictionary entry available here, defining testagy concisely as "the state or condition of leaving a will at one's death," contrasted directly against intestacy. This definition is accurate as far as it goes, but it is notably spare. It does not address partial testagy, the conditions for validity that determine whether testagy exists, or the procedural consequences of the distinction.
Later editions of Black's shifted substantially to "testacy" as the preferred form, and the term "testagy" effectively dropped from active legal vocabulary. Historical sources are therefore more likely to use this spelling than any modern resource. Researchers using nineteenth-century probate treatises or early twentieth-century state probate codes and commentary should expect to encounter "testagy" alongside "testacy" as interchangeable variants.

Jurisdictional Note
No jurisdiction defines "testagy" in a meaningfully different way from another — the concept is universal in Anglo-American probate law. Jurisdictional variation in this area concerns the conditions required for a valid will (execution formalities, capacity standards, witness requirements) rather than the meaning of the status itself.
