Key Takeaways (TL;DR)
How long does a medical malpractice case take? Most cases in Illinois take 2–4 years to resolve. Simple claims might settle within a year, but complex or high-value cases can stretch much longer—especially if they go to trial or involve multiple healthcare providers. The timeline depends on medical reviews, discovery, negotiations, and the court’s schedule.
The Timeline for Medical Malpractice Lawsuits

No two medical malpractice lawsuits follow the same path. Factors like the severity of injuries, the number of defendants, and the amount of investigation needed all influence how long it takes.
Here’s a general timeline for these lawsuits in Illinois:
- Initial Investigation (3-12 months) – Gathering records and consulting medical experts.
- Filing the Lawsuit (1–2 months) – Preparing and serving formal legal complaints.
- Discovery Phase (6–18 months) – Exchanging evidence, taking depositions, and reviewing expert testimony.
- Settlement Talks or Mediation (variable) – Negotiations can happen anytime, but usually after discovery.
- Trial (6–12 months) – If the case doesn’t settle, trial scheduling and proceedings extend the timeline.
- Appeals (optional, 6–24 months) – If either side contests the verdict, appeals can prolong resolution.
Table: Average Illinois Medical Malpractice Timelines by Case Type
| Case Type | Average Timeline | Notes | 
| Simple case, early settlement | 12–18 months | Often resolved after medical review and early talks | 
| Complex case with multiple defendants | 2–3 years | Extended discovery and expert review | 
| High-value or catastrophic injury case | 3–5 years | Often goes to trial or appeal | 
On average, a lawsuit for malpractice in Illinois settles within 2–3 years, but trial cases can take 4 years or more to conclude.
What Causes Delays in Illinois Medical Malpractice Cases?

Several factors influence how long it takes to reach a settlement or verdict. Below are some of the most common elements that can lengthen or shorten a case’s timeline in Illinois.
1. Complexity of Medical Issues
Medical malpractice cases often require multiple expert opinions. For example, proving that a doctor breached the standard of care might involve specialists in surgery, radiology, or anesthesiology. Each expert must review detailed records and testify under oath—processes that take months.
2. Number of Parties Involved
Hospitals, nurses, surgeons, and clinics may all share responsibility. Identifying every liable party takes time, especially when hospitals are owned by multiple entities or when doctors have independent insurance coverage.
3. Discovery Delays

The discovery phase is usually the longest part of a case. Medical malpractice lawyers on both sides exchange documents, take sworn depositions, and subpoena medical records. If one party withholds information or disputes evidence, court intervention can add months of delay. We have also been involved in cases where medical providers have tried to avoid turning over records and had to be compelled via court order.
4. Expert Witness Scheduling
Top medical experts are often practicing physicians with limited availability. Coordinating their schedules for testimony and cross-examination can stretch out proceedings significantly.
5. Settlement Negotiations
Insurers often delay or lowball settlement offers until they see your case’s strength. An experienced medical malpractice lawyer knows how to negotiate strategically and recognize when an offer is fair—or when to push forward to trial.
Statute of Limitations for Illinois Medical Malpractice Lawsuits
Under Illinois law, medical malpractice claims must be filed within 2 years of when the injury was discovered (or reasonably should have been discovered) and no later than 4 years after the act occurred — except for minors, who have up to 8 years but no later than their 22nd birthday, with extensions for certain legal disabilities.
Missing the deadline could permanently bar your right to sue, so it’s crucial to contact a medical malpractice attorney early.
