Indiana Stacking & Multiple Insurance Policies

Indiana statutes permit anti-stacking
IC 27-7-5-5 permits a policy or endorsement to provide that total liability from one accident does not exceed the highest limit under one applicable policy, subject to the statutory minimum. Indiana therefore does not have a blanket pro-stacking rule.
The policy must clearly implement the limitation
Statutory permission is not enough by itself; the accident-date contract must contain effective language. Read other-insurance, limits-of-liability and setoff provisions together with the declarations.
Wagner invalidated ambiguous anti-stacking wording
Wagner v. Yates held the language before the Court ambiguous because it did not clearly refer to other policies or external UIM coverage as the basis for limiting aggregate recovery. The ambiguity was construed against the insurer.
Compare every policy before adding or excluding limits
Create a matrix with insurer, policy, named insured, vehicle, UM/UIM limit, insured status and anti-stacking/setoff wording. Multiple applicable policies do not automatically mean either unlimited stacking or no stacking.
