The Discovery Process: What to Expect After Filing a Lawsuit in Oklahoma

After your personal injury lawsuit is filed, the case enters discovery—the formal process where both sides investigate the facts, gather evidence, and prepare for trial. This phase often feels slow and frustrating to clients. There are written questions to answer, documents to gather, and hours-long depositions to endure. But discovery is where cases are built. The evidence obtained during discovery shapes settlement negotiations and, if necessary, trial presentation. Understanding what happens during discovery—and what you need to do—helps you participate effectively and keeps your case on track.

What Discovery Accomplishes

Discovery serves several purposes in civil litigation.

Information gathering is the primary function. Both sides learn what evidence exists. You discover documents the defendant has about the accident; they obtain your medical records and employment history. Neither side should be surprised at trial—discovery ensures both parties know what they're dealing with.

Case evaluation becomes possible only after discovery. Until you've seen the defendant's documents, taken depositions of witnesses, and obtained expert opinions, you can't truly assess case strength. Many cases that seemed strong reveal problems during discovery; others that seemed difficult become stronger when favorable evidence emerges.

Settlement facilitation often results from discovery. Once both sides understand the evidence, realistic settlement discussions become possible. Cases frequently settle during or shortly after discovery as parties recognize their strengths and weaknesses.

Witness preservation protects against memory loss and unavailability. Depositions create sworn testimony that can be used at trial if a witness becomes unavailable or changes their story.

Types of Discovery

Oklahoma and federal rules provide several discovery mechanisms. Your case will likely involve most of these.

Interrogatories are written questions one party sends to the other, requiring written answers under oath. The defendant will ask about your injury, treatment, prior medical history, employment, and damages. You'll need to work with your attorney to prepare accurate, complete answers. Oklahoma limits interrogatories to 40 (including subparts) in state court; federal court limits them to 25.

Requests for Production ask the other party to provide documents. The defendant will request your medical records, medical bills, tax returns, employment records, photographs, and communications about the accident. You may need to gather documents, sign authorization forms, and help locate materials. Your attorney will request documents from the defendant—accident reports, policies, training records, communications about the incident.

Requests for Admission ask the other party to admit or deny specific facts. These narrow the issues for trial by establishing facts that don't need to be proved. Failure to respond is treated as an admission.

Depositions are oral examinations under oath, with questions asked by opposing counsel and answers recorded by a court reporter. Depositions of parties, witnesses, and experts are typically the most important discovery activity. For a detailed guide to what happens at your deposition, see our article on what to expect as a deposition witness.

Independent Medical Examinations (IMEs) allow the defendant to have you examined by a doctor of their choosing. For guidance on handling this process, see our article on independent medical examinations.

The Timeline

Discovery doesn't happen all at once. It unfolds in stages over months.

Initial disclosures occur early. Under federal rules and some state procedures, parties must automatically disclose certain information—names of witnesses, copies of relevant documents, damage calculations, and insurance coverage—without waiting for formal requests.

Written discovery typically begins after initial disclosures. Interrogatories and document requests are served; responses are due within 30 days (sometimes longer by agreement). This back-and-forth can take several months as both sides request, respond, object, and sometimes argue about what must be produced.

Depositions usually occur after significant written discovery is complete. Parties typically depose each other first, then third-party witnesses. Expert depositions come late in discovery, after expert reports have been exchanged.

Expert disclosure deadlines require parties to identify expert witnesses and provide their opinions by specified dates. Experts then submit to depositions where their methodology and conclusions are challenged.

Discovery cutoff is the deadline, set by the court, after which no new discovery may be conducted. Deadlines vary by court and case complexity but typically fall 6-12 months after the lawsuit is filed.

Your Role in Discovery

Discovery requires your active participation. Here's what to expect.

Answering interrogatories takes time and attention. Your attorney will draft responses, but you'll need to review them for accuracy and provide information the attorney doesn't have—dates, details, names of witnesses. Be thorough and honest; interrogatory answers are sworn statements that can be used against you if they later prove inaccurate or incomplete.

Gathering documents is often your responsibility. You may need to locate tax returns, pay stubs, medical bills not already obtained, photographs, diaries, and other materials. The faster you can gather what's needed, the smoother discovery proceeds.

Signing authorizations allows your attorney to obtain records from third parties—medical providers, employers, insurance companies. You'll sign multiple authorizations during the case.

Preparing for deposition is critical. Your deposition may last several hours. Defense counsel will question you about the accident, your injuries, your treatment, your prior medical history, and your damages. Preparation with your attorney—sometimes including a full practice session—helps you testify effectively.

Attending depositions of other witnesses may be advisable in some cases, though often only attorneys attend. You have the right to be present.

Responding promptly to attorney requests keeps your case moving. Delays in providing documents or reviewing materials can push back deadlines and extend the case.

What the Defense Is Looking For

Understanding the defense's goals during discovery helps you prepare.

Inconsistencies are gold to defense attorneys. Anything you said in written discovery that contradicts what you said at deposition, or that conflicts with medical records, or that differs from testimony of other witnesses—they will use it. This is why honesty and consistency are paramount.

Prior injuries and conditions are always investigated. If you claim back pain from this accident, they will search for any prior back complaints, treatments, or workers' compensation claims. Prior conditions don't defeat your case—you can recover for aggravation of preexisting conditions—but they affect the analysis.

Gaps in treatment raise questions about injury severity. If you stopped treating for months, they'll argue you must not have been that hurt. Be prepared to explain any gaps.

Social media activity is increasingly important. Defense attorneys monitor plaintiffs' public social media for photographs or posts that contradict claimed limitations. A photo of you hiking at a national park while you claim you can't walk undermines credibility. Lock down privacy settings and avoid posting about your physical activities during litigation.

Alternative causes for your injuries get explored. Were you in prior accidents? Do you have a physically demanding job? Did you play sports that might cause the same kind of injury? Defense counsel will develop alternative explanations for your condition.

Common Discovery Disputes

Discovery rarely proceeds without conflict. Common disputes include:

Objections to disclosure arise when one party believes the other is asking for too much, asking for privileged information, or making unreasonable demands. These disputes sometimes require court intervention through motions to compel.

Relevance disputes occur when parties disagree about what subjects are fair game. The defendant might seek years of medical records unrelated to your injuries; you might object that they're fishing for embarrassing information.

Privilege claims protect certain communications—attorney-client communications, work product, and in some cases medical records protected by privilege. Disputes over privilege require careful legal analysis.

Scheduling conflicts frequently arise around depositions. Coordinating schedules of multiple attorneys, parties, and witnesses is challenging. Flexibility helps cases proceed.

How Discovery Affects Your Case

What emerges from discovery shapes everything that follows.

Settlement discussions become realistic. Vague pre-discovery offers often become concrete post-discovery negotiations as both sides understand the evidence. Discovery may produce documents that dramatically help—or hurt—your case.

Case evaluation allows your attorney to give you an honest assessment of likely outcomes. Before discovery, projections are educated guesses; after discovery, they're grounded in evidence.

Trial preparation uses discovery materials directly. Deposition testimony can be used to impeach witnesses who change their story. Documents produced in discovery become trial exhibits. Expert opinions are locked in through deposition.

Strategic adjustments may be necessary. Discovery sometimes reveals weaknesses that affect strategy—perhaps dropping a weak claim, adjusting damage calculations, or settling because the evidence isn't as strong as hoped.

Frequently Asked Questions

How long does discovery take?

Typically 6-12 months, though complex cases may take longer. Courts set discovery deadlines, but these can be extended by agreement or court order.

Do I have to answer every question in interrogatories?

You must answer all proper questions honestly and completely. Your attorney will object to improper questions—those asking for privileged information, that are overly broad, or that seek irrelevant information. Objections are noted, and if the other side presses, the court decides.

What if I don't remember something at my deposition?

Say you don't remember. Never guess. "I don't recall" is a perfectly acceptable answer. If you're shown documents that refresh your memory, you can then provide additional testimony.

Can I refuse to produce documents?

You can object to improper requests, but you cannot simply refuse to produce relevant, non-privileged documents in your possession. Your attorney will review requests and raise appropriate objections.

What happens if I miss discovery deadlines?

Missing deadlines can result in sanctions—from monetary penalties to having claims or defenses dismissed. Always keep your attorney informed about your ability to meet deadlines.

Is everything from discovery public record?

Not necessarily. Discovery materials are exchanged between parties but not filed with the court unless used in motions or at trial. However, discovery materials are generally not confidential—either party could theoretically share them. Protective orders can limit disclosure of particularly sensitive information.
