Mich. R. Evid. 411
As amended through September 25, 2024
Evidence that a person was or was not insured against liability is not admissible to prove whether the person acted negligently or otherwise wrongfully. But the court may admit this evidence for another purpose, such as proving a witness's bias or prejudice or - if controverted - proving agency, ownership, or control.
