People who have been injured and are considering a personal injury claim often have only a vague sense of what the legal process involves — they know it takes time and they know lawsuits happen sometimes, but the specific sequence of events, the typical timeline, and what drives the pace and outcome are largely unknown. Understanding the realistic process helps clients set appropriate expectations, make informed decisions at key junctures, and participate effectively in their own cases rather than experiencing the litigation passively.
Pre-Litigation: The Investigation and Demand Phase
Most personal injury cases begin with an investigation and demand phase that occurs before any lawsuit is filed. The attorney collects evidence of liability — police reports, photographs, witness statements, relevant surveillance footage, any official investigation findings. Medical records documenting the injury, treatment, and prognosis are gathered and reviewed. Once the injured person has reached maximum medical improvement — the point where their treating physicians have determined that further significant recovery is unlikely — the attorney calculates the damages: medical expenses past and future, lost wages, loss of future earning capacity, and the pain and suffering value supported by the specific injuries and their documented impact.
A demand letter is sent to the at-fault party’s insurance company, presenting the liability evidence and damages calculation and demanding a specific settlement amount. The insurance company responds — typically taking 30 to 90 days — with an acceptance, a counter-offer, or a denial. Most cases settle in this pre-litigation phase, avoiding the time and expense of formal litigation. When the insurance company’s position is too far from what the evidence supports to be bridged through negotiation, the attorney files a lawsuit.
Litigation Phase: Filing Through Discovery
Filing the complaint initiates the formal litigation process and imposes court-mandated deadlines. The defendant has a specified period to file an answer. The parties then enter the discovery phase — the formal exchange of information — which typically takes six to twelve months in personal injury cases and longer in complex ones. Discovery includes: written interrogatories (questions answered in writing under oath), requests for production of documents, depositions of key witnesses and parties (recorded examinations under oath), and independent medical examinations by physicians retained by the defense to evaluate the plaintiff’s injuries.
Expert witnesses are disclosed and their opinions exchanged during or after fact discovery. In personal injury cases, experts commonly include accident reconstruction specialists, medical experts who review the injuries and their causation, economists who calculate future lost earnings and care costs, and life care planners who establish the cost of long-term medical needs. The expense of these experts — often $10,000 to $50,000 cumulatively in a complex case — is why personal injury attorneys are selective about which cases they invest in for litigation.
Mediation, Trial, and Resolution
Most cases settle before trial — statistics suggest approximately 95 percent of filed civil cases resolve through settlement rather than jury verdict. Mediation — a structured negotiation facilitated by a neutral mediator — is required by many courts before trial and resolves a large percentage of cases that survive to that point. The mediation gives both sides an opportunity to hear the other’s view of the case evaluated by a neutral professional, which frequently produces the reality check that brings reasonable settlement. If mediation fails, the case proceeds to trial — typically one to five days for a personal injury case — where the jury evaluates liability and damages. The total timeline from accident to resolution ranges from one year (for straightforward cases that settle in pre-litigation) to three to five years (for complex cases that go to trial).
