Personal Injury Discovery Phase Explained: What to Expect in 2025

## What Is the Discovery Phase in a Personal Injury Lawsuit?

Discovery is the formal evidence-gathering stage of a personal injury lawsuit. During discovery, both sides — the plaintiff (you) and the defendant — exchange information, review documents, and interview witnesses under oath. This phase often determines whether a case settles and for how much. Strong evidence uncovered in discovery frequently leads to significantly better settlement offers because the defendant's attorney can see exactly how the case will play out at trial.

In over 70% of cases that reach discovery, the strength of evidence gathered during this phase — not courtroom arguments — ultimately determines the settlement amount.

The Three Core Discovery Tools in Personal Injury Cases

Each discovery tool serves a different purpose and provides different types of evidence to support your claim.

• **Interrogatories:** Written questions both sides must answer under oath within 30 days; your attorney uses these to lock defendants into specific facts about the accident and their liability
• **Depositions:** In-person sworn testimony recorded by a court reporter where attorneys question witnesses, experts, and parties; depositions of the defendant and key witnesses are critical
• **Document requests and subpoenas:** Formal requests for medical records, surveillance footage, maintenance logs, insurance policies, and communications related to the incident

Discovery can last 6 to 18 months in complex cases. Expert witnesses — including accident reconstruction specialists, medical professionals, and economists — are often retained during this phase to calculate full damages. Never withhold information from your attorney during discovery; full disclosure strengthens your case and prevents surprises at trial.
