Additional insured status on professional liability policies

Source: Victor Insurance

Some clients of design professionals think they can be better protected against third-party claims by being included as a named insured or  as an additional insured on a design firm’s professional liability policy. This may be true for some forms of insurance. However, it is not an  option in the Victor and CNA program because the design firm’s client is usually not performing professional services and therefore does not assume the risk that the policy is designed to cover.

A professional liability policy only provides coverage for claims arising from the rendering of those professional services that the insured is  qualified to perform. Since a client does not typically render professional services, it would receive no added protection by being named as an “additional named insured.” Furthermore, naming a client as an “additional named insured” on a professional liability policy may cause  the standard “Insured vs. Insured” policy clause to apply, potentially compromising coverage for a claim from the client against the insured firm.

Unlike other types of insurance policies, the professional liability insurance policy does not make payments to the named insured but rather  pays on behalf of the named insured in the event that the named insured’s negligence in rendering professional services causes damage or injury. Therefore, if the design firm’s client were named as an insured under the design firm’s policy, the client would be unable to collect  damages under the policy since an insured cannot make a claim against itself and recover under the design firm’s CNA professional liability policy.

Although less common, an additional problem occurs if the client has professional engineers, registered architects, or other design  professionals on its staff. If that client were to be added to the design firm’s professional liability policy, that coverage could apply to all of  the professional activities of the client’s in-house design professionals throughout the life of the design firm’s policy. This means that it is  possible that any claim of professional negligence made against a licensed design professional on the client’s staff (whether that design  professional is involved with the design firm’s project or not), would have to be defended—and possibly even indemnified—under the design  firm’s professional Insurance risks  liability insurance policy. In such a situation, the design firm would be providing coverage for an entity  or individual over whom the design firm has no control.

Thus, while it may be clearly beneficial and common for a client to be included as an “additional named insured” under a firm’s general  liability insurance or automobile liability insurance policies, being so named on a policy covering claims arising from the rendering of  professional services is problematic.
