Claims of actual or alleged negligence that arise from providing professional services are covered in a professional liability insurance. These include giving incorrect advice, an omission or failing to deliver a service and cover damages and defence costs up to your policy limits, regarding of whether a mistake was made.
An example of this is when an accountant professional liability insurance could cover the legal and settlement costs if a claim from a client was made that the accountant had filed the taxes incorrectly, causing them to lose a lot of money.
Professional liability policies are usually written on a claims-made basis and so coverage is only available to claims filed during the policy period. The coverage can protect against claims that arise from services provided in the past and for work performed anywhere in the world.
It is essential to understand that professional liability will not cover any claims related to injury to others or any damages to their property. This type of protection is offered by general liability.
