Serving AIG in California? We Handle That.
AIG is one of the largest insurance organizations in the world, and it operates through a complex web of subsidiaries.
Make Sure You’re Serving the Right AIG Entity
AIG is one of the largest insurance organizations in the world, and it operates through a complex web of subsidiaries. Serving “AIG” is not enough — you must name and serve the correct legal entity. American International Group, Inc. is the parent holding company, incorporated in Delaware. While it is frequently named in lawsuits, the actual insurer on your policy is almost always a subsidiary.
Key AIG subsidiaries include AIG Property Casualty U.S., Inc., National Union Fire Insurance Company of Pittsburgh, PA (one of AIG’s primary commercial liability carriers), American Home Assurance Company, Lexington Insurance Company (surplus lines), AIG Specialty Insurance Company, and New Hampshire Insurance Company. Each of these is a separate legal entity with its own policy obligations.
If your claim involves an insurance policy, the entity listed on the declarations page of that policy is the entity that must be served. “AIG” is a brand — the actual insurer could be any one of dozens of subsidiaries. Your attorney can confirm the correct defendant by reviewing the policy documents. All AIG entities registered in California use CSC at 2710 Gateway Oaks Drive.

I have a commercial insurance claim against AIG — how does service work?
Commercial insurance claims against AIG are served through CSC at the Sacramento address, just like any other service. However, AIG’s commercial policies are often issued through specific subsidiaries rather than AIG itself. Work with your attorney to identify the correct issuing entity from your policy documents before filing. Your proof of service should match the entity named in your complaint.
