AUTER DROIT

Definition

Auter droit (also written en auter droit) is a Law French phrase meaning "in the right of another." It describes the legal capacity in which a person acts not on their own behalf but as the representative or fiduciary of another person whose rights are the actual subject of the action or holding. The concept appears most prominently in two recurring contexts: 1. Trusteeship. A trustee holds trust property in auter droit — that is, in the right of the beneficiary (cestui que trust), not as an owner in their own right. The trustee's legal title is instrumental; the beneficial interest belongs to another. 2. Representative litigation. A next friend (prochein amy) who sues on behalf of an infant or incompetent person acts in auter droit — bringing the action in the right of the party who cannot sue independently, not in the representative's own right. The phrase functions as a term of art identifying when legal capacity, title, or standing is derived rather than original.

Common Confusion

Auter droit is sometimes conflated with the distinct plea of auter action pendant (another action pending) or with the concept of autre fois acquit (formerly acquitted). These share the "auter/autre" prefix but address entirely different doctrines — one concerns representative capacity, the others are procedural pleas in abatement or bar. The stray Bouvier entry in this record referencing pending indictments and abatement belongs to those separate doctrines and has no bearing on auter droit proper.

Why It Matters in Research

Researchers will encounter auter droit most often in equity jurisprudence and early trust law materials, where the distinction between holding property in one's own right versus in the right of another carried significant legal consequences — affecting creditors' claims, the right of set-off, and the character of the estate held. The phrase appears in both its standalone form (auter droit) and its prepositional form (en auter droit), and historical sources use both interchangeably. Burrill treats these as a single concept and cross-references them accordingly. Researchers should search both forms in historical corpora. A critical research trap: the Law French spelling "auter" coexists with the Anglo-French "autre" in historical sources. Sixteenth- through nineteenth-century English legal texts may use either, and some use both within the same work. Corpus searches limited to one spelling will miss occurrences of the other. The concept also surfaces obliquely in discussions of privity, standing, and the old common law rules governing who could bring a real action. In that context, auter droit explains why certain parties could maintain actions that would otherwise appear to be brought by someone without a direct interest. For trust law research in particular, understanding auter droit is a prerequisite for reading older equity treatises that use the phrase without definition. The concept connects directly to the distinction between legal and equitable title — foundational to the development of the trust in English law. Researchers tracing the history of fiduciary obligation will find auter droit appearing at the intersection of common law and chancery doctrine.

Historical Dictionary Support

The three source dictionaries agree on the core meaning: auter droit means acting or holding in the right of another, not in one's own right. There is no meaningful divergence on substance. Black's provides the most practical illustration, noting both the trustee-beneficiary relationship and the prochein amy's role in litigation, with a reference to Blackstone's Commentaries (2 Bl. Comm. 176) that grounds the term in foundational English authority. Bouvier's entry is spare — simply "in right of another" — consistent with the term's role as a known term of art requiring little elaboration for the intended audience. Burrill adds the useful cross-reference to the prepositional form "en auter droit," signaling that researchers should treat the two as equivalent. What the historical dictionaries do not address is the procedural significance of the distinction in modern contexts — particularly how auter droit reasoning maps onto contemporary rules governing fiduciary capacity, standing, and representative actions. That analytical work is left to the researcher.
