Services, not just premises
A client may allege an error in advice or work even without physical injury. General liability and professional liability are designed for different kinds of allegations; having one does not establish coverage under the other.
When claims must be reported
Some forms are claims-made and require claims to be made or reported within specified periods. Review the retroactive date, prior-acts treatment and any extended reporting option before changing or ending coverage.
Contracts and policy limits
Describe the services and any subcontracted work. Check whether defense costs reduce the limit, which people or entities are insured, and what the client's contract actually requires.
