Character Evidence and Limits on Proving Conduct by Personality

Learn why character evidence is limited and how it differs from impeachment or other relevant proof.

Character evidence is evidence about a person’s trait, disposition, or general character offered to suggest how the person acted.

In plain language, it is proof that says, “This person is the kind of person who would do that.” Evidence rules often limit this kind of proof because it can distract, prejudice, or invite unfair assumptions.

Why it matters

Character evidence matters because trials should usually decide what happened in the dispute, not punish or reward someone for general personality. The rules around character evidence help control unfair prejudice while still allowing certain uses in limited circumstances.

The term is common in criminal cases, witness credibility disputes, and civil trials where prior conduct is offered.

Where it appears

Character evidence appears in trial objections, motions in limine, witness examinations, impeachment disputes, criminal-defense strategy, and jury-instruction issues.

Practical example

A prosecutor wants to introduce testimony that a defendant is an aggressive person to prove the defendant committed an assault. The court may need to decide whether that is improper character evidence.

How it differs from nearby terms

Character evidence differs from impeachment. Impeachment attacks a witness’s credibility. Character evidence may be offered to prove conduct through a trait.

It also differs from relevance. Character evidence may be relevant in a loose sense but still excluded by a specific evidence rule.
