Liability policies typically require the insured to provide prompt notice of a claim or suit. Notice is regarded as a condition precedent to the insurer’s duty to defend or indemnify. The notice provisions in a typical liability policy seem straightforward. However, issues surrounding notice become complicated when an additional insured, who is typically not a party to the insurance contract and sometimes unnamed in a policy, is involved. Under those situations, courts have had to address, among other issues, the sophistication and resources of the additional insured, whether the additional insured is aware that coverage potentially exists or even that policies potentially exist, whether the jurisdiction requires the additional insured to actually tender the claim or suit or whether another insured’s tender of the claim or suit is sufficient and whether there was late notice or no notice at all by the additional insured. Different jurisdictions have reached different results.
