Definition
Administration durante minore ætate (Latin: "during minority") is a limited form of probate administration granted when a named executor is a minor and therefore legally incapable of acting in that capacity at the time of the testator's death. Because a minor cannot legally discharge the duties of an executor, the court appoints a temporary administrator to manage the estate until the executor reaches the age of majority. At that point, the minor executor may qualify and assume full authority over the estate. The appointment is thus provisional in nature — it expires by operation of law rather than by judicial revocation.
Common Confusion
Durante minore ætate administration is sometimes conflated with administration durante absentia (during absence) or administration pendente lite (during litigation). All three are species of limited or temporary administration, but they arise from distinct circumstances: minority of the executor, unavailability of the executor due to absence, and contested probate proceedings, respectively. Researchers should not treat these forms as interchangeable; the grounds, duration, and terminating conditions of each differ, and historical sources may use "limited administration" as an umbrella term covering all three without sufficient distinction.
Recognized Forms
/SUBTYPES
In some American jurisdictions, particularly as reflected in early New York statutory practice, the circumstance that would give rise to durante minore ætate administration was instead resolved by granting administration cum testamento annexo (with the will annexed) rather than recognizing durante minore ætate as a formally separate appointment. This produced a functional overlap between two nominally distinct categories, a point of practical importance for researchers reading nineteenth-century probate records.
Why It Matters in Research
Researchers working with historical probate records, particularly those predating systematic state codification, will encounter this term in court minutes, letters of administration, and estate inventories. Several research traps are worth flagging.
First, terminology was not uniform. English ecclesiastical court practice, from which American probate procedure descends, used durante minore ætate as a recognized formal category. American jurisdictions absorbed the concept unevenly — some retained the Latin designation, others absorbed the situation into administration cum testamento annexo, and still others addressed it by statute under different labels entirely. A record that says "letters of administration" without qualification may in fact be a durante minore ætate appointment; the limitation will appear in the body of the grant, not necessarily its heading.
Second, the terminating event matters for chain-of-title and estate research. Unlike an administrator appointed because the deceased died intestate, a durante minore ætate administrator has no permanent standing. When the minor executor qualified upon reaching majority, a second set of letters would issue. Researchers tracing estate administration must account for this transfer of authority; gaps or apparent inconsistencies in an estate file may reflect this transition rather than any irregularity.
Third, in jurisdictions that routed the minority problem through cum testamento annexo rather than a standalone durante appointment, the two forms may appear in the same corpus of records without a clear signal that they are addressing the same underlying situation. Cross-referencing the applicable state statute in force at the date of administration is essential.
Historical Dictionary Support
Burrill's Law Dictionary provides the foundational entry under the Latin form durante minore ætate, defining it straightforwardly as administration granted during the minority of an executor, and citing Blackstone's Commentaries (2 Bl. Com. 503) and Coke's Reports (5 Co. 29, 30) as the English authorities. Burrill also notes the New York statutory divergence explicitly: under the Revised Statutes of New York, this situation was handled not as a distinct durante appointment but as a case for granting administration cum testamento annexo, citing 2 Rev. Stat. [69], § 3 and [71], § 14. This is a useful and honest piece of comparative observation for its era.
What the historical dictionaries do not address is the procedural mechanics of the transition — what happened when the minor executor came of age and sought to displace the temporary administrator — nor do they engage with the varying age-of-majority rules that could affect when the limitation expired. Researchers should not assume that the English ecclesiastical framework described by Blackstone and Coke maps cleanly onto any particular American jurisdiction without checking local statutory sources.
Jurisdictional Note
American practice diverged from English ecclesiastical precedent on this point. New York's early statutory framework subsumed the minority situation within cum testamento annexo administration rather than maintaining durante minore ætate as a separate grant. Other states followed English practice more closely or developed their own statutory solutions. Researchers should identify the applicable state statute in force at the time of the administration before drawing conclusions from the form of appointment.
