The Burden of Proof

Aug 31, 2026 - Personal Injury by Cross & Smith

In a legal dispute, one party bears the burden of proving that their facts are correct. The burden of proof typically rests with the person who brought the lawsuit, and it includes two components:

• Burden of Production – This is the duty to provide enough evidence to support a legal case
• Burden of Persuasion –  This is the duty to convince the judge or jury that the claim is true, and is subject to evidentiary legal standards such as clear and convincing evidence

Think of the burden of production as the foundation of the case. It includes documents, witness statements, expert testimony, and other elements that create the factual basis for your legal claim. If you cannot meet these requirements, your case will be dismissed before it is heard by a judge or jury. The burden of persuasion is the evidentiary standard – such as “beyond a reasonable doubt,” “preponderance of the evidence,” or “clear and convincing evidence” that must be met. 

The burden of proof is a legal principle that ensures lawsuits are based on facts rather than conjecture. 

Legal Standards To Meet the Burden of Proof

The highest evidentiary standard in the burden of proof is “beyond a reasonable doubt.” This is the standard in criminal cases. The principle of people being considered innocent until proven guilty is the heart of the American criminal system. To meet this evidentiary standard, a prosecutor has the burden of proof to establish guilt. It is a standard that is a bit short of absolute certainty, but it means that the evidence, as presented by the prosecutor, leaves no reasonable alternative conclusion other than the defendant’s guilt. There are various ways that a Tuscaloosa personal injury lawyer can present reasonable doubt. These include:

• Discrediting witness testimony
• Questioning the chain of custody when physical evidence forms part of the case
• Highlighting the lack of direct evidence
• Presenting an alternate theory of the case
• Offering expert testimony 

Civil cases typically carry an evidentiary standard of either “clear and convincing evidence” or “preponderance of the evidence.” Clear and convincing evidence is evidence that is so strong that it convinces a judge or jury of the truth of the claim. Sometimes it is articulated as “highly probable” or with a 70% – 75% certainty. It is a lower standard than “beyond a reasonable doubt” but a higher standard than “preponderance of the evidence.” In Alabama, clear and convincing evidence is required by statute when a plaintiff is seeking punitive damages for fraud, malice, or wantonness. 

In most civil cases in Alabama, including for personal injury lawsuits, the evidentiary standard is a “preponderance of the evidence.”  This means that the evidence presented by a plaintiff is more likely than not true. That is, the judge or jury must believe that the plaintiff’s case is at least 51 percent true. Note that defendants do not need to prove that they were not negligent, or that they did not cause the injury. Nor do defendants need to prove that their version is true, or present some alternative theory of what happened. Defendants only need to present enough evidence for the judge or jury to believe that the plaintiff cannot prove it is more likely than not that their case is true. 

Another evidentiary standard, known as “some credible evidence,” is the lowest standard and can be used in emergency situations before the court requiring immediate attention, such as in temporary protective orders. 

Challenges in Meeting The Burden of Proof

Often there are challenges in meeting the burden of proof. Personal injuries are not always as easy to prove as they might seem on first blush. For example, medical malpractice lawsuits often involve nuances, subtleties, and conflicting testimony, and the evidence must strongly suggest that the defendant was negligent at the time of the accident. To prove negligence, Alabama requires that the defendant show four legal elements to make a valid claim:

• The defendant had a duty of care to the plaintiff
• The defendant breached that duty of care
• The defendant’s breach of the duty of care was the cause of the injury
• The injury is compensable

If the plaintiff can prove these elements by a preponderance of the evidence, then he can prevail in the lawsuit.  

Can the Burden of Proof Shift?

While the general rule is that the burden of proof rests with the plaintiff, sometimes it shifts. In Alabama, the burden of proof shifts to the defendant when asserting the affirmative defense of contributory negligence. A finding that a plaintiff was even 1% negligent in a lawsuit bars the plaintiff from recovering any damages at all from a defendant. 

Other common affirmative defenses asserted by the defendant that shift the burden of proof from the plaintiff to the defendant include the statute of limitations having run and self-defense. Special legal doctrines can also shift the burden of proof to the defendant in certain types of lawsuits. 

Understanding the burden of proof and the pertinent evidentiary standards helps lawyers evaluate the relative strength of a case and develop an appropriate strategy. In an Alabama civil case involving a personal injury from a car accident or a defective medical device, for example, your lawyer needs only to prove that it is more likely than not that your facts are true. It’s also important to note that settlement negotiations frequently hinge on realistic assessments of the burden of proof.
