Helping to Take the Risk Out of Your Professional Services

Mistakes, unfortunately, happen in business. Even with best practices in place and a conscientious staff, errors in performing professional services can occur resulting in an unhappy client and the potential for a lawsuit for financial damages. In some instances, it’s a case of he-said, she-said. Either way, it can be costly for a firm if the proper insurance program isn’t in place to step up.

NorthStar Insurance Services, a leading insurance broker in New England, offers a wide range of professionals with insurance coverage designed to respond in the event of an error or omission claim.

Professional Liability for Your Firm or Practice

Professional Liability insurance shields you from third-party lawsuits alleging you provided negligent professional services, failed to uphold contractual promises (for example, critical deadlines were missed), provided incomplete or unacceptable work, or made mistakes or omissions. What you should keep in mind is that you don’t have to be at fault to be sued. Just one unhappy client that names your business in a lawsuit can cost you time and money in dealing with the suit. A Professional Liability policy will pay your legal expenses, regardless of whether the claim or suit has any merit as well as any settlement or judgment up to the policy limit for a covered loss. Be aware: Your General Liability coverage does not step in for disputes involving professional liability claims.
