Definition
A guardian by statute is a guardian appointed for a minor child by the deed or last will of the child's father, authorized to hold custody of both the child's person and estate until the child reaches the age of majority. The appointment derives its legal force not from the natural relationship of the parties or from court order, but from a specific statutory grant of authority enabling a father to designate a guardian by testamentary or written instrument.
The foundational statute is the English Act of 12 Charles II, c. 24 (1660), which first gave fathers this power of testamentary appointment. Prior to this statute, the common law recognized no such mechanism; the right was purely a creature of legislation. American jurisdictions adopted the principle broadly in their early reception of English law, though the specific contours varied by state.

Common Confusion
GUARDIAN BY STATUTE vs. GUARDIAN BY NATURE: These categories are regularly conflated in older texts. A guardian by nature arises automatically from the parent-child relationship — at common law, the father held this status by virtue of paternity alone, with custodial rights over the person but typically not the estate of the child. A guardian by statute, by contrast, is created by an affirmative act of appointment (deed or will) and extends authority over both person and estate. Black's notes that "natural guardian" is a popular rather than a technical expression, and some historical sources use the terms interchangeably — a trap for researchers reading across periods or jurisdictions.
GUARDIAN BY STATUTE vs. TESTAMENTARY GUARDIAN: These terms are functionally synonymous in most usage. "Testamentary guardian" emphasizes the mode of appointment (by will), while "guardian by statute" emphasizes the statutory authority enabling that appointment. When a guardian is appointed by deed rather than will, "guardian by statute" is the more precise term. Modern sources predominantly use "testamentary guardian."
GUARDIAN BY STATUTE vs. GUARDIAN BY APPOINTMENT OF COURT: A court-appointed guardian derives authority from judicial order rather than from the parent's private act. Modern guardianship practice is overwhelmingly court-appointment driven. A researcher encountering "guardian by statute" in a historical document should not assume court involvement.

Why It Matters in Research
Researchers working in pre-twentieth-century American legal sources will encounter "guardian by statute" as a live, operative category — not an archaic curiosity. Because the category is creature of a specific English statute received into American law, its scope and application varied across states depending on whether and how the Statute of 12 Charles II was adopted or superseded by local legislation. In some jurisdictions, the father's power extended only to appointment by will; in others, deed appointment was equally valid.
The key research trap: modern guardianship statutes have largely absorbed and replaced this category without always preserving the terminology. A researcher tracing a guardianship dispute from the nineteenth century into the twentieth may find the same functional relationship described under entirely different labels. Conversely, a researcher reading a nineteenth-century probate or chancery record must recognize that "guardian by statute" implies paternal testamentary appointment — not court supervision of the kind modern readers would expect.
The limitation to the father's appointment power is historically significant and worth flagging in any research touching gender and parental rights. At common law and under the original statute, the mother had no equivalent power of testamentary appointment. Equity courts sometimes intervened to extend or modify this, and American statutory reform progressively equalized parental rights — but the baseline in historical sources is paternal-only authority.
Guardianship over both person and estate in this category distinguishes it from more limited guardianships. Where a historical source refers to a guardian by statute, researchers should expect the guardian's authority to encompass management of the child's property, not merely physical custody — relevant to probate, real property, and contract disputes involving minors.

Historical Dictionary Support
Black's Law Dictionary is the primary source available here, and its treatment is consistent across the relevant entries. Black's correctly identifies the statutory origin in 12 Car. II, c. 24, notes the broad American reception, and directs readers to Blackstone's Commentaries (1 Bl. Comm. 462), Stephen's Commentaries (2 Steph. Comm. 339–340), and Kent's Commentaries (2 Kent, Comm. 224–226) — the standard triumvirate for foundational English-derived American doctrine.
The Black's entry also notes the "natural guardian" conflation issue, flagging that the term is "popular rather than technical" — a useful signal that the distinction between guardian by nature and guardian by statute was already blurred in practice by the time Black's was compiled. Researchers should treat any historical source using "natural guardian" with care, as it may actually describe a guardian by statute in substance.
What the historical dictionary entry does not address: the progressive erosion of this category through family law reform, the equalization of maternal appointment rights, and the eventual displacement of the category by modern testamentary guardian statutes subject to court confirmation. For developments after the mid-nineteenth century, the historical dictionary sources require supplementation from statutory history and treatises specific to the relevant jurisdiction.

Jurisdictional Note
American reception of the Statute of 12 Charles II varied significantly. Some states enacted their own testamentary guardian statutes closely tracking the English model; others modified the father's appointment power substantially, including earlier equalization of maternal rights. Researchers should identify the specific state statute governing the period in question rather than assuming uniform adoption of the English framework.
