Definition
"Use and manage" is a phrase appearing in legal instruments — particularly wills, trusts, and conveyances — that defines the scope of authority granted to a fiduciary or beneficiary over property. As a term of art, it describes a power to exercise dominion over property in the ordinary course of administration: to employ it for its intended purpose, to maintain it, and to make decisions incident to its upkeep or productive use. Critically, the phrase does not, standing alone, confer a power to consume, alienate, or sell property for the personal benefit of the holder. Any right of sale implied by "use and manage" is generally limited to purposes of reinvestment — not conversion to personal support.
The phrase also appears in regulatory and organizational contexts. In federal land management law, "use and manage" describes the government's authority over public lands and natural resources, encompassing planning, permitting, and resource allocation. In LLC governance, the phrase may describe the operational authority of members or managers to conduct the business of the entity.
Common Confusion
"Use and manage" is sometimes read as coextensive with full ownership powers, including the power to sell and consume. Courts have consistently rejected this reading in the testamentary context. The phrase grants administrative authority — not beneficial ownership. A person empowered to "use and manage" property for a family's benefit cannot redirect that authority to serve only their own maintenance. The power of sale, when implied at all, runs only to reinvestment for the benefit of the intended beneficiaries, not to liquidation for the holder's personal use. Researchers should be alert to conflation of this phrase with broader grants such as "use, manage, and dispose of" or "use, enjoy, and consume," which carry materially different legal consequences.
Why It Matters in Research
This phrase is a trap for the unwary in historical will and trust contests. Its apparent breadth — "use and manage" sounds comprehensive — has repeatedly misled parties into assuming it authorizes sale or consumption of assets. Courts have drawn a sharp line between administrative authority and beneficial power, and the Kentucky case referenced in Bouvier's is an example of that line being enforced at the expense of a widow who assumed broader rights than the instrument conveyed.
Researchers working in probate records, estate litigation, or historical trust instruments should treat "use and manage" as a phrase whose scope is always context-dependent. The surrounding language — particularly the presence or absence of words like "dispose," "consume," "for her own benefit," or "for the benefit of the family" — controls the outcome. The modifier phrase is as important as the operative words themselves.
In the regulatory and public lands context, "use and manage" has a distinct statutory lineage. Federal land management statutes employ the phrase to define agency authority, and its scope there is governed by administrative law principles and statutory mandate rather than common law rules of construction. Researchers crossing between private law and public law sources should not assume the phrase carries the same meaning across these domains.
In the LLC context, "use and manage" or its functional equivalents appear in operating agreements to demarcate member authority from manager authority, and state LLC statutes often supply default rules where the agreement is silent. The phrase in this setting describes operational governance authority, not property rights in the traditional sense.
Historical Dictionary Support
Bouvier's Law Dictionary addresses "use and manage" narrowly and precisely, grounding its definition in a Kentucky Court of Appeals decision. The Bouvier's treatment makes two points: first, that the phrase, even when linked to a right to sell and invest proceeds for a family's benefit, confers no right to consume or sell for the holder's personal support alone; and second, that any implied power of sale is limited to reinvestment purposes. Bouvier's does not attempt a general theory of the phrase — it illustrates through a concrete judicial application. This is characteristic of Bouvier's approach to operational phrases in instruments, which tends toward case-anchored explanation rather than abstract definition.
What Bouvier's does not address is the phrase's life outside the testamentary context. Its entry is useful for probate and trust research but provides no purchase on the regulatory or organizational meanings that have developed in the twentieth century. Researchers should treat the Bouvier's entry as authoritative for its domain — historical will construction — while recognizing that the phrase has accumulated additional legal meanings in other bodies of law that require separate investigation.
Jurisdictional Note
The core principle — that "use and manage" does not confer a power to consume or alienate for personal benefit — reflects a broadly shared rule of will and trust construction, though specific outcomes depend heavily on the full instrument language and governing state law. In public lands law, the phrase operates under federal statutory frameworks that vary by land category and agency.
