Definition
To interplead is to bring competing claimants into court so that their rival claims to a single fund, debt, or property can be resolved between them — relieving the party holding the asset (the stakeholder) of the risk of paying the wrong person or facing multiple liability.
The verb describes what the stakeholder does (files an interpleader action or motion) and what the claimants do in response (litigate against each other). The stakeholder is not the defendant in the ordinary sense; the claimants become the adverse parties. Once a court permits the interpleader, the stakeholder typically deposits the disputed funds with the court and is discharged from further liability, leaving the claimants to fight it out.
The term is closely tied to its noun form, INTERPLEADER, which refers to the procedural device or the action itself. INTERPLEAD is the verb: a party interpleads when it invokes that device.

Common Language
Modern common usage (Wiktionary): "To plead against each other, or go to trial between themselves, as the claimants in an interpleader."
Historical common usage (Webster's 1913): "To plead against each other, or go to trial between themselves, as the claimants in an interpleader."
Both common definitions capture part of the picture but locate the action in the claimants rather than the stakeholder. In legal practice, the party that interpleads is most often the stakeholder — the insurance company, bank, or escrow holder — not the competing claimants. Researchers who read "interplead" as describing only the claimants' conduct will miss the stakeholder-initiated mechanics that define modern interpleader practice.

Common Confusion
INTERPLEAD vs. INTERPLEADER: These terms circulate interchangeably in older sources, which creates noise in corpus searches. INTERPLEAD is the verb (the act of invoking the procedure); INTERPLEADER is the noun (the procedural device, the action, or sometimes the stakeholder itself in antiquated usage). Anderson's uses both in the same entry without distinguishing them. Modern procedural rules — Federal Rule of Civil Procedure 22 in U.S. federal practice — use INTERPLEADER exclusively as the noun. When reading pre-twentieth-century sources, expect INTERPLEAD to carry the weight of both.

Why It Matters in Research
The primary research trap is terminological bleed between the verb and noun forms across historical sources. Bouvier and Anderson both treat INTERPLEAD as the operative term and treat INTERPLEADER as subordinate or derivative. By the time of the Federal Rules of Civil Procedure (1938) and the Federal Interpleader Act (28 U.S.C. § 1335), the noun INTERPLEADER had become the dominant term in procedural literature, and INTERPLEAD receded to describing the act of invoking that procedure. Corpus searches limited to one form will miss significant material from the other period.
A second trap: historical equity practice and modern statutory/rule-based practice are structurally different. The old bill of interpleader in equity required the stakeholder to have no independent interest in the fund and to have incurred no independent liability to either claimant. Modern rule interpleader (Rule 22) and statutory interpleader (§ 1335) relaxed these requirements. Sources predating the Federal Rules describe a narrower device; applying their definitions to modern practice distorts both.
For insurance law researchers specifically, interpleader actions are a primary mechanism for resolving competing life insurance beneficiary claims — including disputes implicating the slayer rule, divorce-decree conflicts, and competing assignments. The Law Mind Insurance Encyclopedia entry on life insurance proceeds is the natural companion source. Life insurers are among the most frequent stakeholders in modern interpleader filings, and the case law has developed specific doctrine around insurer obligations, timing of the deposit, and attorney's fee awards.
Jurisdictional variation matters here: state interpleader practice varies considerably, and some states retain equity-influenced requirements that federal practice abandoned decades ago. Older state court decisions may reflect the stricter bill-of-interpleader requirements even when cited as general authority.

Historical Dictionary Support
Anderson and Bouvier agree on the core function: a mechanism by which a holder of disputed property or a debt can force competing claimants to resolve their dispute judicially, thereby protecting the holder. Both frame it in equitable terms — the stakeholder's inability to safely pay without court guidance is the animating concern.
Anderson's is more practically detailed, explicitly identifying the stakeholder's posture (owing a debt to one of the parties but uncertain which) and the remedy sought (protection in making payment). This framing reflects the classical bill of interpleader: a defensive equity proceeding initiated by a reluctant payer.
Bouvier's is more abstract, emphasizing the incidental nature of the interpleaded issue — tried "before the principal cause can be determined." This framing suggests an older procedural context in which interpleader arose within a pending suit rather than as a standalone action, which was common in English Chancery practice.
Neither historical source addresses statutory interpleader or rule-based interpleader, which did not exist when these dictionaries were compiled. Neither discusses the relaxation of the "no independent interest" requirement. Researchers should treat both entries as describing the equity baseline, not the modern procedural default.

Jurisdictional Note
U.S. federal practice operates under two parallel interpleader tracks: rule interpleader (Fed. R. Civ. P. 22) and statutory interpleader (28 U.S.C. § 1335), which differ in amount-in-controversy requirements, service of process, and venue. State interpleader practice is not uniform — some states track the federal rules closely, others retain equity-court requirements or have independent statutory frameworks. Research in state court decisions should not assume federal procedural assumptions apply.
