Provisions within professional liability insurance policies stating that if
more than one claim results from a single wrongful act, and if claims are made
during more than one policy period, the insured is entitled to the limit
applicable when the first claim was made rather than the sum of the
limits that were applicable to the policy periods during which all claims were
made. In recent years, this term has replaced the term "noncumulation of
limits provision," which has essentially the same meaning in both common
usage and within policy forms. The related claims provision is also sometimes
referred to as the "interrelated claims provision," although this
usage is less common.
