How it applies
Common Examples
6
Impeachment in Civil Contract Suit
Ruby Rivera, a neighboring farmer, testified for the plaintiff that wheat met moisture standards. The defendant offered her twelve-year-old arson conviction from a farm-equipment dispute to attack credibility. The court weighed the conviction's industry-specific probative force against the risk that jurors would view Rivera as dangerous and excluded the evidence.
Exempt Property Valuation Dispute
Rowan Russell, surviving spouse, sought household furnishings and an automobile under the exempt-property statute. The estate offered photographs of luxury items to show the claimed value exceeded the cap. The court excluded several photographs whose emotional impact on the jury substantially outweighed their limited help in valuing the items.

Study Supplements
Ryan Roberts served pretrial disclosures listing deposition excerpts and documents thirty-five days before trial. Rhea Reynolds filed written objections to foundation and hearsay a month later. The court held the objections waived but still considered a Rule 403 prejudice objection to one graphic exhibit that could be raised at trial.
Uncharged Misconduct in Drug Trial
Renata Russo faced charges of possessing cocaine. The government offered a prior heroin-distribution conviction to show knowledge. The court admitted the evidence after finding sufficient proof the prior act occurred and that its probative value on knowledge was not substantially outweighed by unfair prejudice.
Foreclosure Standing Challenge
Riverfront Developments sought to foreclose on a lost negotiable note. Raphael Rivera, the borrower, challenged the plaintiff's right to enforce. The court admitted an affidavit detailing the loss after determining its probative value on standing was not substantially outweighed by any risk of confusion.
Stipulation to Prior Conviction
Radiance Media sued a former employee for breach. The employee offered to stipulate he was a felon on a felon-in-possession count. The court excluded the full judgment record because the name and nature of the prior offense carried a risk of unfair prejudice that substantially outweighed its minimal additional probative value.
Common questions
Frequently Asked
4
How does Rule 403 interact with impeachment by prior conviction under Rule 609?+
In civil cases or when the witness is not the accused, a felony conviction is admissible to attack truthfulness unless its probative value is substantially outweighed by unfair prejudice under Rule 403. When the witness is the criminal defendant, a stricter balancing applies that excludes the conviction if prejudicial effect merely outweighs probative value.
Supporting sources
What types of harm does Rule 403 address beyond unfair prejudice?+
The rule also permits exclusion when probative value is substantially outweighed by dangers of confusing the issues, misleading the jury, undue delay, wasting time, or needless presentation of cumulative evidence.
Supporting sources
Does Rule 403 ever override more specific evidence rules?+
No. Rule 403 serves as a general safety valve for situations not covered by specific rules. It does not override categorical rules such as the automatic admission of crimen falsi convictions under Rule 609(a)(2).
Supporting sources
When may a party raise a Rule 403 objection to pretrial disclosures?+
Objections under Rules 402 and 403 to the admissibility of materials identified in pretrial disclosures are preserved and may be raised at trial even if not listed in the fourteen-day written objection window.
