Waiver of Stacking Upheld

The Right to Stack UM Coverage Can Be Waived

People who insure their cars in Pennsyvania have the right to stack coverages for uninsured motorist (“UM”) or Underinsured Mortorist (“UIM”) coverages if they insure more than one vehicle with their insurer. The Pennsylvania statutes allow an insured to waive the right to stack coverages and thereby generate a lower premium. In Glenn B. Shipp and Denise A. Shipp v. the Phoenix Insurance Company, 2012 Pa.Super. 167 (Pa.Super. 08/14/2012) a Pennsylvania appellate court was asked to resolve a dispute over the effectiveness of a waiver of stacking after the trial court allowed stacking even though there had been a waiver.

The Phoenix Insurance Company (“Phoenix”) appealed the entry of an order granting summary judgment in a declaratory judgment action filed by the administrators of the Estate of Shipp (“the Shipps”).


Plaintiff Glenn B. Shipp applied for personal automobile insurance and signed a rejection of stacked underinsured coverage form on September 12, 2002. The form was signed in the presence of his insurance agent. The policy was issued by the Phoenix Insurance Company. Plaintiffs paid less for non-stacked coverage than they would have paid for stacked coverage. The amount of underinsured motorist benefits available under the policy was $100,000.

This insurance policy was renewed every six months and the declaration sheets issued to Plaintiffs showed underinsured motorist benefits in the amount of $100,000 non-stacked. On February 3, 2006, Plaintiffs’ minor son, Michael R. Shipp, was severely injured in a motor vehicle accident. He was a passenger of a motor vehicle driven by William R. Flemming, who admitted liability for the accident. Michael died on February 11, 2006 as result of the injuries sustained in the accident.

On the date of the accident, Plaintiffs and their son were insured 2005 Toyota Corolla and the 2004 Toyota Highlander. Both vehicles had collision and comprehensive coverage.

Following the accident and Michael’s death, Plaintiffs made a claim to Defendant for the limits of underinsured motorist benefits in the amount of $200,000. This amount is the $100,000 underinsured motorist benefit stacked for two vehicles. Defendant responded by tendering $100,000 for the undisputed underinsured motorist benefit limit, but denied that Plaintiffs were entitled to stacked coverage.

On appeal, Phoenix contends that the entry of summary judgment was in error because Phoenix was not compelled to obtain a second waiver of stacked uninsured/underinsured (“UM/UIM”) coverage limits when the Shipps replaced an existing vehicle with a new vehicle under the insurance policy between Phoenix and the Shipps.


This case involves the interpretation of the a statute that allows for stacking of uninsured and underinsured benefits and option to waive the limit for each vehicle. When more than one vehicle is insured under one or more policies providing uninsured or underinsured motorist coverage, the stated limit for uninsured or underinsured coverage shall apply separately to each vehicle so insured. Notwithstanding the provisions of the statute a named insured may waive coverage providing stacking of uninsured or underinsured coverages in which case the limits of coverage available under the policy for an insured shall be the stated limits for the motor vehicle as to which the injured person is an insured.

The wrinkle in the case before the court is the fact that there was no additional vehicle being added to the policy; rather, the new vehicle was a replacement for an existing vehicle. Thus, where the policy went from covering two vehicles to three, the policy continuously covered two vehicles only. The coverage on the replacement vehicle will continue uninterrupted as long as the Shipps give notice to Phoenix. The initial waiver signed by the Shipps, because only two cars were covered, was found to be still valid and bar the stacking of coverage.

The fact that the Shipps’ added collision coverage when they bought the Toyota in 2005 does not constitute a purchase of a new policy for the purpose of triggering the need to obtain another waiver as to stacking. The matter of importance in all of these cases and whether a new waiver of stacked coverage is required. Indeed, both before and after the purchase of the 2005 Toyota, the UM/UIM coverage available to the Shipps’ remained at all times $200,000 stacked, $100,000 unstacked.

Since no new insurance coverage was purchased under such circumstances, Phoenix would not need to re-obtain waiver of stacked coverage from the Shipps. Of course, it is possible that under the terms of some hypothetical insurance policy, a replacement vehicle could somehow be interpreted as the acquiring of new coverage, however, under the terms of the policy, it is not. For all these reasons the appellate court found that it was error to permit the recovery of stacked limits.


When auto insurance is purchased every state requires that the insured be provided an option to buy UM or UIM coverage and, in states like Pennsylvania, they also have the right to stack the limits for each vehicle. Such provisions always authorize the insured to save premium by waiving UM/UIM or stacking provisions. The insured in this case waived it and tried imaginative arguments to try to get the insured an additional $100,000.

All insureds should consider the potential effect of a waiver. Good practice would be to carry at least as much UM/UIM coverage to protect yourself that is equal to that bought to protect others you may injure negligently.
