When medical negligence seriously harms you or a loved one, the decision to pursue legal action is not one made lightly. Missouri law places an additional safeguard at the very beginning of the process. The Missouri affidavit of merit for malpractice cases, mandated in the Missouri Revised Statutes, is designed to ensure that only cases with genuine merit move forward in the courts. Understanding this step is critical, as failing to comply can mean your case is dismissed before it begins.

With more than 40 years of litigation experience and a dedicated team that includes full-time medical professionals, we ensure no stone is left unturned in protecting our clients’ rights.
Key Takeaways
- Missouri requires an Affidavit of Merit: In most medical malpractice lawsuits, plaintiffs must file an affidavit stating a qualified medical expert believes the claim has merit.
- Deadline is critical: The affidavit must generally be filed within 90 days of filing the malpractice lawsuit, unless the court grants an extension.
- Expert qualifications matter: The affidavit must come from a legally qualified medical expert familiar with the applicable standard of care.
- Failure to file can dismiss the case: Missing the affidavit deadline or submitting an insufficient affidavit can result in dismissal of the lawsuit.
- Purpose is to prevent frivolous claims: Missouri’s affidavit requirement helps ensure only legitimate medical negligence cases move forward.
Medical Malpractice Cases Are Complex, and the Law Adds Extra Hurdles
Medical malpractice cases in Missouri are highly technical, requiring a deep understanding of both law and medicine. Unlike many personal injury claims, they cannot proceed on allegations alone. Missouri law requires plaintiffs to file an affidavit of merit within a strict timeframe to confirm the case has medical support.
This rule is meant to prevent frivolous lawsuits, but it can also become a barrier for victims who do not have the right legal team. Missing this step or failing to meet the affidavit of merit requirements outlined in Missouri law can lead to immediate dismissal, regardless of the severity of your injuries.

What Is the Missouri Affidavit of Merit Requirement?
When you file a medical malpractice lawsuit in Missouri, you must also file an affidavit stating that:
- You have obtained a written opinion from a legally qualified healthcare provider who practices in the same or substantially similar specialty as the defendant;
- The provider has reviewed your medical records;
- The provider believes, in their opinion, that the defendant failed to use the degree of skill and learning ordinarily used by a reasonably prudent healthcare provider under similar circumstances; and
- The provider believes this failure directly caused or contributed to your injuries.
This affidavit must be filed within 90 days of the defendant’s answer to your lawsuit, though the court can grant one 90-day extension if there is good cause.
Failing to file this affidavit, or filing one that does not meet statutory requirements, almost always leads to a dismissal of your claim.
