In a previous post, we addressed blanket additional insured endorsements and the role they play in passing insurance obligations downstream. In short, the purpose of a “blanket” endorsement is to grant additional insured status to any company as required in a written contract with the named insured. This obligation often begins in the prime contract where the owner requires additional insured status on the general contractor’s insurance. However, the general contractor typically attempts to pass this obligation downstream to its subcontractor by including a requirement in the subcontract that both the general contractor and owner are named as additional insureds. But what happens if there is no written agreement between the named insured and the company seeking additional insured status, or if there are multiple required additional insured entities and only some have contractual privity with the subcontractor?
