Definition
In law, "acquired" carries two distinct but related senses depending on context:
1. INTESTATE SUCCESSION SENSE: Property is "acquired" when it comes to an intestate decedent by any means other than gift, devise, or descent from a parent or the ancestor of a parent. This classification matters because many jurisdictions historically applied different rules of distribution depending on whether property was acquired (earned or purchased by the decedent independently) versus inherited from a specific family line. The distinction determined who among the surviving relatives was entitled to take.
2. RIGHTS AND PROPERTY GENERALLY: A right or interest is "acquired" when it does not arise naturally or at birth, but rather through a person's own acts, procurement, or legal transactions — such as purchasing property, entering a contract, or assuming a position of authority. Acquired rights contrast with natural or inherent rights.

Common Language
Modern common usage (Wiktionary): Developed after birth; not congenital.
Historical common usage (Webster's 1913): Gained by one's own exertion or skill; as, acquired knowledge; acquired tastes.
The common meaning of "acquired" — something gained through effort or experience, as opposed to something innate — does carry over into law, but the legal term carries precise technical weight in the intestate succession context that the ordinary word does not. Whether property was "acquired" versus "descended" in the succession sense is a formal classification with concrete distributional consequences, not merely a descriptive distinction. Researchers using historical sources should not assume the conversational meaning is sufficient.

Common Confusion
ACQUIRED vs. INHERITED: In intestate succession law, these are not simply opposites. Property may be received by gift from a non-parent, by purchase, or by operation of law, and all of these qualify as "acquired." "Inherited" in colloquial use covers any property received from a deceased relative, but the legal classification is more precise: only property descending from a parent or parental ancestor falls outside the "acquired" category for distribution purposes. Conflating the two can produce significant errors when reading historical probate records or intestacy statutes.
ACQUIRED RIGHTS vs. NATURAL RIGHTS: Jurisprudentially, "acquired rights" (also called "vested rights" in some frameworks) are those created through legal transactions or social institutions. They are distinct from natural rights, which are treated as pre-legal. The distinction appears in early constitutional commentary and international law doctrine. Do not assume Black's use of "acquired rights" maps neatly onto modern vested rights doctrine, which has its own distinct technical meaning.

Why It Matters in Research
The intestate succession definition is the primary context in which "acquired" functions as a formal legal term of art in the historical common law tradition. Researchers working with 19th-century probate records, estate litigation, or intestacy statutes — particularly from Southern and border states — should watch for this classification carefully. The rule distinguishing acquired property from ancestral or descendant property was a live doctrinal issue in many jurisdictions and generated its own body of case law.
The broader "acquired rights" formulation appears in early constitutional and natural law discussions and resurfaces in international law in the context of state succession and treaty obligations. These are distinct research threads and should not be merged.
In the modern corpus, "acquired" most commonly appears as a modifier in compound terms: after-acquired property, after-acquired evidence, after-acquired title. These compound doctrines each have independent technical meanings and their own research trails. Researchers who encounter "acquired" alone in an older source should determine which sense is operative before proceeding — the intestate classification rule is easy to overlook because it has largely been displaced by modern statutory intestacy schemes that do not expressly preserve the distinction.
Jurisdictional variation in historical intestacy law is significant here. The acquired/ancestral property distinction was more robustly developed in some states (particularly in the South and in states following civil law influence) than in others.

Historical Dictionary Support
Both editions of Black's define "acquired" in the intestate succession context with substantially identical language, anchored to the same Tennessee case (In re Miller's Will, 2 Lea 54). The second edition adds the "acquired rights" sub-entry drawn from an Arkansas case, which extends the definition beyond probate into general jurisprudence.
Neither edition flags how thoroughly the acquired/ancestral distinction had already been eroding by the time of their publication, nor do they note the variation across jurisdictions in whether this distinction had any operative effect on intestate distribution schemes. The entries are descriptive rather than analytical, and researchers should not read them as confirming that the doctrine was uniformly applied.
The "acquired rights" language in the second edition draws on the natural law tradition (sovereignty, property, command) and is useful primarily as a period artifact — it reflects how late-19th-century American lawyers framed rights claims in philosophical terms that later gave way to more positivist frameworks.

Jurisdictional Note
The distinction between acquired and ancestral property in intestate succession was operative in a number of American jurisdictions during the 19th century, particularly in states with civil law influences or those drawing on older English doctrine. Most modern intestacy statutes have abandoned the classification entirely. Researchers working in Tennessee, Arkansas, or Louisiana historical materials should confirm which distributional rules were in force at the relevant time.
