When you retain a subconsultant under C401, you inherit liability for their work. Professional liability insurance and indemnification provisions are the two primary mechanisms for managing that exposure. Get them right, and you have financial protection when things go wrong. Get them wrong, and you're exposed to claims with no backstop.

Professional liability (PL) insurance covers the risk of loss caused by a design professional's negligent performance of professional services. It's different from commercial general liability (CGL) insurance in fundamental ways. PL policies pay on behalf of the insured when their negligence causes damage. CGL policies cover broader categories of third-party injury or property damage. You need to understand this distinction because the ARE tests it.

One of the most frequently misunderstood aspects of PL insurance: clients cannot be named as additional insureds on professional liability policies. This trips up candidates and practitioners alike. PL policies cover the risk of negligent professional services. The client doesn't perform professional services, so they don't have the risk the policy covers. And adding a client as an insured would trigger the "insured vs. insured" exclusion, preventing the client from making a claim against the policy.

Indemnification clauses are the contractual counterpart to insurance. They shift liability for losses from one party to another. Three types exist: broad form (indemnitor covers losses regardless of fault), intermediate (indemnitor covers losses when both parties are at fault), and comparative (indemnitor covers only their proportional share of fault). AIA contracts typically use the comparative approach.

For project management, the connection between insurance and indemnity is direct: your indemnification promises should never exceed what your insurance covers. If you agree to broad-form indemnification but your PL policy only covers negligence-based claims, you have an uninsured gap.
