Definition
To file, in legal usage, is to deliver a document to a court, tribunal, administrative agency, or public office for the purpose of official deposit, registration, or placement in the permanent record of a proceeding or transaction.
As a noun, a file is the collection of documents so deposited — the assembled record of a case, proceeding, or administrative matter.
The term encompasses several related but distinct actions:
1. Filing with a court: Delivering a pleading, motion, brief, notice, or other paper to the clerk of court so that it becomes part of the official case record. Most jurisdictions now permit or require electronic filing (e-filing) as an alternative or supplement to physical deposit.
2. Filing with an agency: Submitting a form, application, return, or report to a government agency — the most common modern context being tax returns filed with the IRS or state revenue authorities, and regulatory documents filed with agencies such as the SEC.
3. Filing as public registration: Recording an instrument — such as a financing statement, deed, or judgment — in a public registry to give constructive notice to third parties. In this sense, filing has legal consequences independent of any pending proceeding.
As a verb in procedural law, "to file" is often distinguished from "to serve": filing places the document with the tribunal; service delivers it to the opposing party. Both steps may be required, and failure to complete either within applicable deadlines can be fatal to a claim or defense.

Common Language
Modern common usage (Wiktionary): To file means to place papers in a folder or cabinet for organized storage, or to submit a formal document to an authority (e.g., "file a complaint," "file your taxes").
Historical common usage (Webster's 1913): "To place upon file, or among the records of a court; to deposit in the custody of the proper officer; to put on record." Webster's also notes the noun meaning: "a thread or wire on which papers are strung" — referring to the physical method of binding official papers in sequence.
The common meaning has grown closer to the legal meaning over time, particularly as ordinary speakers now routinely "file taxes" and "file complaints." The meaningful gap that remains is in the legal consequences: in law, the moment of filing is often a precise legal event with immediate effect — triggering deadlines, establishing priority, or perfecting rights. Ordinary usage treats filing as administrative housekeeping; legal usage treats it as a legally operative act.

Common Confusion
FILE (deposit/register) vs. SERVE: Filing and service are companion requirements in litigation but are legally distinct. A document filed with the court is in the official record; a document served on a party has been formally delivered to the adversary. Many procedural rules specify different deadlines for each, and proof of service is often itself a document that must be filed. Researchers reviewing historical pleadings should check whether the source's procedural rules required both steps and whether any certificate of service appears in the file.

Why It Matters in Research
The word "file" appears on virtually every page of a litigation record, but its precise legal meaning has evolved significantly and varies across contexts. Three research traps are worth flagging:
Timing rules have changed dramatically. What it means to "file" something on time — whether the clock runs on the date of mailing, physical delivery, or receipt by the clerk — has shifted with procedural reforms and the advent of e-filing. Historical sources reflect pre-digital assumptions; a filing that would be timely under a modern mailbox rule might have been untimely under earlier strict receipt rules, and vice versa.
Electronic filing creates new source types. Court records after e-filing adoption are timestamped to the minute and maintained in electronic docketing systems. Earlier paper records may show only a date stamp from the clerk. The evidentiary weight and searchability of these two record types differ substantially when reconstructing procedural history.
Tax filing is a distinct sub-domain. In the tax context, "file" has a specialized meaning shaped by the Internal Revenue Code and agency regulations. Filing status (single, married filing jointly, married filing separately, head of household) is a technical classification that determines the applicable rate schedule and threshold amounts — it is not simply a description of who submitted the return. Researchers working in the Law Mind Tax Encyclopedia will find that filing requirements and filing status entries treat the term with considerably more granularity than general legal dictionaries provide.
Public notice filing (UCC, deeds, judgments) is a third distinct context. Here, filing is a self-executing legal act: a properly filed financing statement under Article 9 of the UCC perfects a security interest as against third parties. The act of filing creates legal priority, not merely a record. Historical research in this area requires attention to the specific filing office, the indexing rules of the jurisdiction, and whether the instrument was filed in the right place with the right content — defects that would not appear from the face of the document itself.

Historical Dictionary Support
Rapalje & Lawrence give a compact and reliable account: to file is "to deposit a paper or document in the proper office, so as to become a part of the record." They treat filing as a procedural act of deposit, tied to the physical placement of documents with a court or public officer. Their definition reflects the common law tradition in which the clerk's office was the custodian of the record and filing was synonymous with delivery into that custody.
What historical dictionaries generally omit — and Rapalje & Lawrence are no exception — is any treatment of the consequences of filing in non-litigation contexts. The modern proliferation of administrative filings, tax returns, securities disclosures, and UCC registrations means that the term now carries legal freight well beyond its traditional procedural home. The historical record is sound on what filing means in court; it is silent on what it means when the IRS or the SEC is the receiving party.
The etymological note in Webster's 1913 — that "file" derives from the wire or thread on which documents were physically strung — is a minor historical curiosity that occasionally surfaces in older opinions and treatises. It is not legally operative but can help explain archaic references to documents being "on file" in a literal, physical sense.

Jurisdictional Note
Filing rules — deadlines, methods, fees, and the moment at which filing is deemed complete — are among the most jurisdiction-specific procedural rules in practice. Federal courts operate under the Federal Rules of Civil or Criminal Procedure; state courts operate under their own codes, which vary considerably. Researchers should never assume a filing rule from one jurisdiction maps onto another without verification.
