Rule Text
When evidence of a person's character or character trait is admissible, it may be proved by testimony about the person's reputation or by testimony in the form of an opinion. On cross-examination of the character witness, the court may allow inquiry into relevant specific instances of the person's conduct. When a person's character or character trait is an essential element of a charge, claim, or defense, the character trait may also be proved by relevant specific instances of the person's conduct.
Plain English Explanation
Rule 405 answers the 'how' question: once you have determined that character evidence is admissible under Rule 404, how can you prove it? The rule provides two tiers of proof depending on the purpose.
In most situations, character can only be proved through reputation or opinion testimony. A witness can testify about the person's reputation in the community or give their personal opinion about the person's character trait. Specific instances of conduct generally cannot be used on direct examination, but the cross-examiner can ask 'did you know' or 'have you heard' questions about specific acts to test the character witness's knowledge and basis.
The second tier applies in the rare cases where character is an essential element of the claim, charge, or defense. In these situations — such as defamation (character of the plaintiff), negligent entrustment (character of the person entrusted), or child custody disputes — specific instances of conduct can be proved on direct examination. This is because character is not being used circumstantially to suggest action in conformity; it is itself the thing being litigated.
Key Points
- 1Generally, character is proved by reputation or opinion testimony — not specific acts on direct
- 2On cross-examination, specific instances may be inquired into to test the witness's basis
- 3When character is an essential element of the case, specific instances of conduct are permitted
- 4The 'did you know' / 'have you heard' cross-examination technique tests the character witness's credibility
Common Exam Issues
- Distinguishing cases where character is used circumstantially (reputation/opinion only) from cases where character is an essential element (specific acts allowed)
- Cross-examination of character witnesses with 'did you know' questions about prior bad acts
- Identifying the rare situations where character is an essential element — defamation, negligent entrustment, entrapment defense
