When a medical mistake causes serious harm or loss, patients and families are often left dealing with pain, emotional trauma, and financial stress. Once the immediate shock settles, one of the most common questions people ask is:
“How long does a medical malpractice lawsuit take?”
The answer is rarely simple. Medical malpractice lawsuits are among the longest and most complex types of personal injury cases. Some resolve in a year, while others can take several years. Understanding why these cases take time—and what happens at each stage—can help reduce uncertainty and frustration.
This guide explains the full timeline of a medical malpractice lawsuit in plain, easy-to-understand language, making it useful for both everyday readers and law practices educating potential clients.
What Is a Medical Malpractice Lawsuit?

A medical malpractice lawsuit is filed when a healthcare provider—such as a doctor, nurse, hospital, or clinic—fails to provide proper care, and that failure causes injury or death to a patient.
Common examples include:
- Misdiagnosis or delayed diagnosis
- Surgical mistakes
- Medication or dosage errors
- Birth injuries
- Anesthesia errors
- Failure to monitor or treat a condition
A lawsuit must prove more than just a bad outcome. It must show that the provider did not follow accepted medical standards and that this directly caused harm. This requirement is a major reason why these cases take time.
Average Timeline: How Long Do These Lawsuits Usually Take?
On average, a medical malpractice lawsuit takes:
- 1 to 2 years for simpler cases
- 2 to 4 years (or more) for complex cases
There is no universal timeline, but most cases fall within this range. Let’s walk through each stage to understand why.
Stage 1: Initial Consultation and Case Evaluation (Weeks to Months)
The process begins when a patient or family contacts a medical malpractice attorney. During this phase, the lawyer will:
- Listen to what happened
- Review basic medical facts
- Identify potential negligence
- Request medical records
Not every medical injury qualifies as malpractice. Lawyers must be careful and selective because these cases require significant time and financial resources.
Why this stage takes time:
- Medical records can be lengthy and difficult to obtain
- Lawyers must evaluate whether the case is legally strong
Typical timeframe:
A few weeks to several months
Stage 2: Medical Records Review and Expert Opinions (3–6+ Months)
This is one of the most critical—and time-consuming—steps.
Medical malpractice lawsuits require medical experts. These experts must review records and confirm that:
- The standard of care was violated
- That violation caused the injury
Experts are often doctors with busy schedules, and they must conduct detailed reviews before giving opinions.
Many states also require an affidavit or certificate of merit, confirming expert support before filing a lawsuit.
Why this stage takes time:
- Thousands of pages of medical records
- Multiple specialists may be needed
- Expert availability can be limited
Typical timeframe:
3 to 6 months, sometimes longer
Stage 3: Filing the Lawsuit (1–2 Months)
Once expert support is secured, the attorney files the lawsuit in court. This includes:
- Preparing legal documents
- Naming defendants (doctors, hospitals, clinics)
- Serving legal notice to all parties
The defendants then have a set time to respond.
Typical timeframe:
1 to 2 months
Stage 4: Discovery Phase (6 Months to 1.5 Years)
Discovery is often the longest phase of a medical malpractice lawsuit.
During discovery, both sides:
- Exchange medical records and documents
- Submit written questions
- Take depositions (sworn testimony)
- Question expert witnesses
- Analyze hospital policies and procedures
Doctors, nurses, administrators, and experts may all be questioned.
Why discovery takes so long:
- Complex medical facts
- Many witnesses and experts
- Scheduling challenges with healthcare professionals
Typical timeframe:
6 months to 18 months (sometimes longer)
Stage 5: Settlement Negotiations (Can Happen Anytime)
Settlement discussions can happen:
- Before filing
- During discovery
- After expert depositions
- Right before trial
Some lawsuits settle early if fault is clear. Others only settle after both sides fully understand the risks of trial.
Insurance companies often delay serious negotiations until:
- Experts are disclosed
- Evidence is fully developed
- Trial becomes a real possibility
Timeframe:
Unpredictable—can be weeks or months
Stage 6: Trial Preparation and Trial (Several Months)
If no settlement is reached, the case goes to trial.
Trial preparation includes:
- Finalizing witness lists
- Preparing expert testimony
- Organizing evidence
- Jury selection
Medical malpractice trials require explaining complex medical issues in simple terms, which takes time.
Trial length:
- Several days to multiple weeks
Reaching trial often means the case has been active for 2 to 3 years.
Stage 7: Appeals (Optional, But Lengthy)
If one side appeals the verdict, the lawsuit continues.
Appeals focus on legal errors, not new evidence, and can add:
- 6 months to several years
Not all cases are appealed, but it is common in high-value medical malpractice cases.
Factors That Affect How Long a Medical Malpractice Lawsuit Takes
Several key factors influence timing:
- Complexity of the Injury
Birth injuries, brain damage, or permanent disability cases take longer.
- Number of Defendants
Cases involving multiple doctors or hospitals move slower.
- State Laws and Court Schedules
Some courts have heavy backlogs that delay trials.
- Expert Availability
Medical experts are essential but often hard to schedule.
- Insurance Company Strategy
Aggressive defense tactics can extend the case.
Why Medical Malpractice Lawsuits Take Longer Than Other Injury Cases
Compared to car accidents or slip-and-fall cases, medical malpractice lawsuits take longer because:
- Expert testimony is mandatory
- Medical standards must be proven
- Defendants strongly fight claims
- Insurance coverage amounts are higher
These cases are detailed by necessity—not delay.
Is a Long Lawsuit Always a Bad Thing?
Not always.
A longer case often means:
- Stronger evidence
- Better expert support
- Increased settlement value
Quick resolutions can sometimes undervalue serious injuries.

Final Thoughts
So, how long does a medical malpractice lawsuit take?
In most cases:
- 1–2 years for straightforward claims
