For years, Maryland law—specifically Insurance Code Section 19-513—expressly prohibited the stacking of insurance policies. This meant that for uninsured/underinsured motorist coverage, the insurer was liable to its insured for the full amount of the accident victim’s damages minus the amount paid by the liability carrier or the Defendant.
After years of criticism for this, the Maryland legislature finally changed the law. As of July 1, 2018, insurance companies who write private auto policies in Maryland are required to offer something called Enhanced Underinsured Motorist Coverage (EUIM). Insureds who chose to add EUIM to their policy will be able to “stack” coverage to ensure they receive full compensation up to their UIM limits. This means that drivers with EUIM can get a policy limit settlement and still get the full policy limits of their UIM coverage.
Here is a simplified example to demonstrate how stacking will work for drivers with the new EUIM coverage and for drivers who don’t have EUIM coverage:
