The documents in a legal case file fall into roughly nine groupings: client intake and fee paperwork, pre-suit investigation materials, pleadings, discovery, privileged work product and privilege logs, motions and court orders, trial preparation documents, final resolution paperwork, and the correspondence and billing records that run through the entire matter. Even a straightforward case produces dozens of items across these categories, and complex litigation can fill boxes. What follows walks through each grouping in the order a file typically grows.
Intake and Pre-Suit Investigation
The file opens before anything is filed in court. The first document is usually a client intake form capturing contact information, a description of the underlying events, names of other people involved, and any deadlines the client already knows about. Sitting next to it is documentation of a conflict-of-interest check confirming the firm does not already represent someone on the other side of the same matter.
A fee or retainer agreement follows. It defines the scope of the representation and how the attorney will be paid. Contingency-fee agreements must be in writing, signed by the client, and state the percentage the attorney will receive at each stage along with how litigation expenses will be handled.1American Bar Association. Model Rules of Professional Conduct Rule 1.5 – Fees
The rest of the intake section holds the raw evidence gathered before suit is filed: police reports, accident photographs, medical summaries, contracts at issue, internal memos from client interviews, and preliminary legal research. These materials often determine whether the attorney takes the case at all.
Pleadings
Pleadings are the formal documents that launch the lawsuit and fix each side’s position. A judge or opposing counsel usually reviews them first, and they control the issues the case will actually address.
The complaint (called a petition in some courts) lays out the court’s authority to hear the case, the factual allegations, the legal claims, and the relief the plaintiff is seeking.2Legal Information Institute. Complaint Filed with it is the summons, a court-issued document that names the parties, directs the defendant to respond, states the deadline, and warns that failing to respond will result in default judgment.3Legal Information Institute. Federal Rules of Civil Procedure Rule 4 – Summons Proof that both documents were formally delivered to the defendant, known as service of process, goes into the file as well.
The defendant’s answer responds to each allegation by admitting it, denying it, or stating insufficient knowledge, and raises any affirmative defenses. If the defendant claims the plaintiff owes them something, the answer may include a counterclaim. Amended versions of pleadings belong in the file too, since courts sometimes allow parties to revise their pleadings as new facts emerge.
Discovery Materials
Discovery is usually the heaviest section. Federal rules require parties to make certain initial disclosures automatically, including the names of people with relevant knowledge and copies of supporting documents.4Legal Information Institute. Federal Rules of Civil Procedure Rule 26 – Duty to Disclose; General Provisions Governing Discovery Beyond those, several specific discovery tools each generate their own paperwork.
Interrogatories are written questions one party sends to the other, answered in writing and under oath. In federal court, each side is limited to 25 interrogatories including subparts unless the court allows more.5Legal Information Institute. Federal Rules of Civil Procedure Rule 33 – Interrogatories to Parties The file keeps the questions, the answers, and any objections.
Requests for production ask the opposing party to turn over documents, electronically stored information, or tangible things, and can designate the format for electronic files.6Legal Information Institute. Federal Rules of Civil Procedure Rule 34 – Producing Documents, Electronically Stored Information, and Tangible Things, or Entering onto Land, for Inspection and Other Purposes The file stores the requests, responses, objections, and the produced documents themselves.
Requests for admission narrow the issues for trial by asking the opposing party to confirm specific facts or acknowledge the authenticity of documents. Anything not denied within 30 days is automatically treated as admitted for the rest of the case.7Legal Information Institute. Federal Rules of Civil Procedure Rule 36 – Requests for Admission
Deposition transcripts record sworn out-of-court testimony from witnesses and parties. In federal court, each deposition is limited to one day of seven hours unless the court orders otherwise, and the testimony can be captured by stenography, audio, or video.8Legal Information Institute. Federal Rules of Civil Procedure Rule 30 – Depositions by Oral Examination The file includes the full transcript, any video recording, and all exhibits marked during the deposition.
Expert witness disclosures are their own subcategory. When a party retains an expert who must provide a written report, federal rules require the report to contain a complete statement of the expert’s opinions and reasoning, the facts and data considered, any supporting exhibits, the expert’s qualifications and publications from the past 10 years, a list of cases where the expert testified during the prior four years, and a statement of compensation.4Legal Information Institute. Federal Rules of Civil Procedure Rule 26 – Duty to Disclose; General Provisions Governing Discovery
Subpoenas to non-parties round out the section. A subpoena can command someone outside the lawsuit to attend a deposition, produce documents or electronically stored information, or allow inspection of property. Before serving a document subpoena on a non-party, the requesting party must provide notice and a copy of the subpoena to every other party.9Legal Information Institute. Federal Rules of Civil Procedure Rule 45 – Subpoena The file retains the subpoena, proof of service, and whatever was produced in response.
Privileged Materials and the Privilege Log
Some of what is in the file never leaves it. Documents and tangible things prepared in anticipation of litigation are generally shielded from discovery under the work-product doctrine, which covers legal research memos, case strategy notes, draft briefs, and internal analyses prepared by the attorney or anyone working under the attorney’s direction. Courts protect the attorney’s mental impressions, conclusions, and legal theories even when other work product must be produced.4Legal Information Institute. Federal Rules of Civil Procedure Rule 26 – Duty to Disclose; General Provisions Governing Discovery
When a party withholds documents by claiming attorney-client privilege or work-product protection, federal rules require a description of what’s being withheld in enough detail for the other side to evaluate the claim, without revealing the privileged content.4Legal Information Institute. Federal Rules of Civil Procedure Rule 26 – Duty to Disclose; General Provisions Governing Discovery In practice that means a privilege log listing the author, recipients, date, and a brief subject-matter description for each withheld document. The privileged materials and the log both live in the file.
Motions and Court Orders
Between the pleadings and the ending, most cases generate a stack of motions and judicial orders. Early on, the court issues a scheduling order that limits the time for joining new parties, amending pleadings, completing discovery, and filing motions, and may set dates for pretrial conferences and trial. Once entered, it can only be modified for good cause.10Legal Information Institute. Federal Rules of Civil Procedure Rule 16 – Pretrial Conferences; Scheduling; Management
Discovery motions come next. When one side refuses to answer interrogatories, produce documents, or cooperate, the other side can file a motion to compel after certifying it tried in good faith to resolve the dispute without court intervention.11Legal Information Institute. Federal Rules of Civil Procedure Rule 37 – Failure to Make Disclosures or to Cooperate in Discovery The file keeps the motion, the opposing brief, and the court’s ruling.
Dispositive motions can end the case. A motion for summary judgment argues that there is no genuine dispute of material fact and that the moving party is entitled to win as a matter of law.12Legal Information Institute. Federal Rules of Civil Procedure Rule 56 – Summary Judgment These motions arrive with extensive supporting materials, including declarations, exhibits, and legal briefs. Motions to dismiss and motions for judgment on the pleadings sit in the same section.
Motions frequently rely on sworn statements. Under federal law, an unsworn declaration signed under penalty of perjury carries the same weight as a notarized affidavit, provided it includes the required attestation and is dated and signed.13Office of the Law Revision Counsel. 28 U.S. Code 1746 – Unsworn Declarations Under Penalty of Perjury Every declaration and affidavit submitted in support of or opposition to a motion belongs in the file, alongside the court orders resolving each motion.
Trial Preparation Documents
If the case does not settle or resolve on motion, a trial preparation section fills out in the weeks before trial. Federal rules require pretrial disclosures at least 30 days before trial: a final witness list identifying everyone the party expects to call and anyone it might call if needed, designations of any deposition testimony to be presented, and an exhibit list identifying each item to be offered into evidence.4Legal Information Institute. Federal Rules of Civil Procedure Rule 26 – Duty to Disclose; General Provisions Governing Discovery The opposing party has 14 days to object, and untimely objections generally waive admissibility challenges.
In jury cases, each side submits proposed jury instructions setting out the legal standards the jury should apply, either at the close of evidence or earlier if the court directs.14Legal Information Institute. Federal Rules of Civil Procedure Rule 51 – Instructions to the Jury; Objections; Preserving a Claim of Error The proposals from both sides and the final instructions given belong in the file, since any discrepancy can become a basis for appeal. Trial briefs, motions in limine asking the court to exclude certain evidence before trial, and voir dire notes fill out this section.
Final Resolution Documents
Every file ends with paperwork that officially closes the matter. Most civil cases settle. When they do, the file contains the executed settlement agreement spelling out the payment amount, payment schedule, and any conditions like confidentiality clauses or mutual releases. To formally end the court case, the parties file a stipulation of dismissal signed by all parties who have appeared, which terminates the action without needing a court order.15Legal Information Institute. Federal Rules of Civil Procedure Rule 41 – Dismissal of Actions
When the court decides the case, the file contains the final judgment. Federal rules require every judgment to be set out in a separate document, prepared, signed, and entered by the clerk of court.16Legal Information Institute. Federal Rules of Civil Procedure Rule 58 – Entering Judgment Post-judgment activity follows: motions for a new trial, motions to alter the judgment, any notice of appeal, and documentation confirming the judgment has been satisfied or the settlement funds disbursed. In many jurisdictions, the party who received payment must file an acknowledgment of satisfaction of judgment to release any liens that attached while the judgment was outstanding.
Correspondence and Billing Records
Two categories run through the entire life of the file rather than sitting in one phase. Correspondence captures every letter, email, and significant communication between the attorney and client, between opposing counsel, and between the attorney and the court. Engagement letters, pre-suit demand letters, settlement negotiation exchanges, and scheduling notices all go here. Many firms preserve electronic communications in native format to retain metadata, which matters if a communication later becomes relevant to a dispute over what was said and when.
Billing records track the time and expenses invested in the case: time entries, expense receipts, invoices sent to the client, and records of payments received. In contingency-fee cases, the billing section focuses on expenses rather than hours. These records matter beyond the attorney-client relationship. In fee-shifting cases, where the losing party pays the winner’s legal costs, courts scrutinize the billing records when deciding whether the claimed fees are reasonable.
What Happens to the File After the Case Closes
The file does not disappear when the matter ends. When representation terminates, attorneys have an ethical obligation to surrender papers and property the client is entitled to and refund any unearned fees.17American Bar Association. Model Rules of Professional Conduct Rule 1.16 – Declining or Terminating Representation The firm keeps its own copy longer.
Financial records tied to the representation, including retainer agreements, billing statements, trust account ledgers, and disbursement records, should be kept for at least five years after the matter closes under the ABA’s model financial recordkeeping standards.18American Bar Association. Model Rule on Financial Recordkeeping – Preface Many firms retain the substantive case file even longer, particularly in matters involving minors, real estate, or ongoing obligations where the documents could become relevant again years later. Specific retention periods vary by jurisdiction and practice area. Most firms maintain a written retention policy and notify the client before destroying any file.
