What Is Burden of Proof?
Burden of Proof is the responsibility to present enough reliable evidence to support a legal claim or defense. In a civil medical malpractice case, the injured patient generally must establish the facts needed to show that negligent medical care caused harm. The required level of proof depends on the type of proceeding.

Key Takeaways About Burden of Proof
- The responsible party may differ between a claim and a defense.
- Evidence must connect medical care to the claimed injury.
- Burden of proof is not the same as the amount of evidence.
How Burden of Proof Works

Burden of Proof determines which party must support a position with evidence. In a medical malpractice claim, the patient typically presents evidence about the medical provider's conduct, the applicable professional duty, the departure from accepted care, and the resulting injury. The opposing party may challenge those points or present evidence supporting a defense.

The burden can shift during a case when a party raises a separate defense or legal issue. The decision-maker then evaluates whether the evidence meets the applicable standard of proof. Medical records, testimony from qualified experts, treatment history, and evidence about the patient's condition may help connect the care at issue with the claimed harm. The burden concerns responsibility for proving an issue, while the standard describes how convincing the proof must be.

From the Atlanta Auto Law team
When we review a medical malpractice matter, we organize the evidence around each required legal element. Our team compares medical records, treatment timelines, expert opinions, and the claimed injury to assess whether the available proof supports the theory of negligence.
Burden of Proof in Practice: A Real-World Example
A patient claims that a delayed diagnosis caused a serious injury. The patient may need evidence showing what the provider should have recognized, how the care departed from that duty, and how the delay caused the injury.
