Litigating and defending cases involving additional insureds may very well be a whole new ball game, so be careful. Decades of seminal cases may no longer apply. By adding just a few sentences to their additional insured endorsements, the Insurance Services Office (ISO) may very well have altered the future of additional insured coverage and related litigation.
That’s what happened on April 1st, 2013. With just one revision ISO may have wiped out decades of caselaw involving additional insureds. While ISO is not the only provider of insurance forms to the insurance industry, they are a major provider and industry influence.
It appears that Appellate Courts have yet to give their interpertation of the revised forms.
