Definition
A woman appointed to administer the estate of a person who died intestate (without a valid will), or otherwise without having named an executor. The appointment is formalized through letters of administration issued by a probate or surrogate court. The administratrix holds the same powers, duties, and liabilities as a male administrator: collecting and preserving estate assets, paying debts and taxes, and distributing the remainder to lawful heirs.
The term is the feminine grammatical form of *administrator* and carries identical legal content. It does not denote a lesser or different office — only a different grammatical gender marker applied to the person holding it.

Common Language
Modern common usage (Wiktionary): A female administrator.
Historical common usage (Webster's 1913): A woman who administers; especially, one who administers the estate of an intestate, or to whom letters of administration have been granted; a female administrator.
The common and legal meanings align closely here, which is unusual. The gap worth noting is one of scope: in ordinary language, "administrator" suggests broad managerial authority. In probate law, the role is court-created, court-supervised, and legally constrained in ways that general usage does not convey. An administratrix acts as a fiduciary, not a free agent.

Common Confusion
ADMINISTRATRIX vs. EXECUTRIX: An executrix is a woman named in a will by the testator to carry out its terms. An administratrix is appointed by the court when there is no will, when the will names no executor, or when a named executor cannot or will not serve. The distinction matters at every stage of estate research: different court processes, different sources, and different legal standards govern each role. Conflating them in historical documents is a research error with real consequences for tracing estate chains.
ADMINISTRATRIX vs. ADMINISTRATOR: Functionally and legally identical. The only difference is the gendered suffix. Modern legal drafting and many jurisdictions have abandoned the feminine form entirely in favor of the gender-neutral "administrator." Researchers encountering "administratrix" in documents are dealing with historical or formally traditional usage, not a distinct legal category.

Why It Matters in Research
The term is a reliable marker of historical legal records. Administratrix appears frequently in probate court filings, estate inventories, bonds, and court orders from the colonial period through the mid-twentieth century. Its decline tracks the broader shift toward gender-neutral legal language, which accelerated in the 1970s and 1980s. Most contemporary statutes and court rules now use "administrator" for all appointees regardless of sex.
Researchers working in older corpora — particularly pre-1950 probate records, equity court proceedings, and reporter headnotes — should expect the feminine form to appear without any signal that it differs substantively from the male counterpart. Indexes and digests from that era may classify cases separately under "administratrix" rather than folding them under "administrator," so searches limited to one term may miss relevant material.
Bouvier's notes an important practical point: marriage of the administratrix does not automatically terminate her appointment or her capacity to sue in that capacity. This was a live legal question in the nineteenth century because a woman's legal identity could merge with her husband's upon marriage (coverture). Courts in several states held that the administratrix's representative capacity survived her marriage — a distinction that matters when tracing whether estate proceedings continued validly after a woman's personal status changed.
Burrill's entry contains an anomaly: after defining administratrix in the probate sense, the text pivots mid-entry to discuss an entirely unrelated concept in European law (a maritime association of private armed vessels). This appears to be a typographical or binding error in the source — the second passage belongs to a different headword (likely *Admiralty* or a related term). Researchers relying on Burrill's for this entry should disregard that passage entirely.

Historical Dictionary Support
All four source dictionaries agree on the core definition without variation: a woman who administers an estate, specifically one to whom letters of administration have been granted. The uniformity reflects the term's simplicity — it is a gendered grammatical variant, not a term with contested doctrinal content.
Bouvier's is the most substantively useful of the four, adding case authority on the marriage question and flagging the Webster's definition as confirmation that common and legal usage converged. Black's (both editions) and Burrill's are sparse, providing the bare definitional formula without elaboration. None of the historical dictionaries address the term's eventual obsolescence or the gender-neutralization movement in legal language — a gap that is significant for researchers oriented toward twentieth-century and contemporary sources.

Jurisdictional Note
The feminine form "administratrix" has been formally retained in some jurisdictions longer than others and in some still appears in older statutory text. Most U.S. states and the federal courts now treat "administrator" as gender-neutral by statute or rule. Researchers should check the applicable jurisdiction's probate code to determine whether the feminine form has any independent operative significance or is simply archaic usage.
