Breach Of Duty
Breach of duty means that someone failed to act with the level of care that a reasonable person would have used in the same situation.
What it actually is
In a negligence case, the plaintiff must prove that the defendant owed a legal duty of care and then broke that duty by acting (or failing to act) in a way that fell short of the expected standard. This element appears after establishing duty and before proving causation and damages. The court compares the defendant's actual conduct to what an ordinary, prudent person would have done under similar circumstances.
Why it matters in your case
Proving breach of duty is essential because without it, even if someone was injured, there is no legal liability for negligence. Practically, the jury or judge will decide whether the defendant's actions were reasonable, which often determines the outcome of the case.
The common misunderstanding
Many people think that any mistake or accident automatically counts as a breach of duty, but the law requires a failure to meet the standard of reasonable care, not just an unfortunate result.
