Michigan Duty to Defend, Reservations of Rights & Liability Coverage Defense

Michigan’s duty to defend is broader than the duty to indemnify. Coverage counsel must compare the allegations and potentially covered liability to the policy while preserving exclusions and indemnity questions through an appropriate reservation or coverage action.

Liability Defense

Defense and indemnity are separate insurance obligations

Michigan duty-to-defend authorities, including the American Bumper and Kirschner line, treat the defense obligation as broader than the ultimate duty to pay a judgment.

Potential covered liability can trigger a defense

The liability insurer should compare the complaint and known potentially relevant facts to the insuring agreement, definitions, exclusions, and endorsements. A claim may require a defense even if later-developed facts establish that the insurer has no duty to indemnify. Conversely, allegations that clearly fall outside the policy do not create coverage simply because the insured needs a defense.

Reservation of rights preserves disputed coverage issues

When the insurer accepts the defense but disputes indemnity for one or more theories, exclusions, persons, vehicles, or damages, the reservation should identify the policy provisions and the factual/coverage issues that remain open. A vague reservation creates avoidable uncertainty for the insured, claimant, defense counsel, and later coverage court.

What the insured and claimant should preserve

  • Complaint and amended pleadings.
  • Complete liability policy and endorsements.
  • Tender of defense and insurer response.
  • Reservation-of-rights correspondence.
  • Coverage opinions or declaratory-action pleadings that are discoverable or otherwise available.
  • Settlement demands and communications showing excess exposure.

Defense counsel retained by the insurer represents the insured defendant, not the insurer’s coverage position. Coverage questions, settlement authority, and litigation defense should be kept conceptually separate even when the insurer funds both processes.

Bottom line. The Michigan defense duty asks whether the claim is potentially covered; indemnity asks what the insurer ultimately must pay. Preserve that distinction from the first tender through settlement or judgment.
