Professional Liability
Protection for Professional Services
What Does Professional Liability Insurance Cover?
Professional liability insurance, often called Errors & Omissions or E&O insurance for certain professions, is designed around allegations that professional advice, specialized services, decisions, records, or recommendations caused a client financial harm.
Errors & Mistakes
May help address qualifying claims involving incorrect information, inaccurate documents, calculation errors, professional mistakes, or other alleged errors in the services provided.
Omissions & Failure to Perform
May help when a client alleges that an important task, recommendation, disclosure, filing, service, or other professional responsibility was not completed.
Professional Negligence
May address certain allegations that professional services did not meet the level of skill, care, or judgment expected for the profession.
Legal Defense
Depending on the policy, coverage may help pay qualifying attorney fees, investigation expenses, expert witnesses, court costs, settlements, or judgments.
Examples From Professional Services
When Might Professional Liability Insurance Be Used?
Incorrect Advice
A client alleges that professional advice, recommendations, evaluations, or instructions caused an unexpected financial loss.
Missed Deadline
A filing, application, report, project, or other professional deadline is missed and the client claims financial harm.
Incomplete Service
A client claims that expected professional services were incomplete, incorrect, delayed, or inconsistent with the agreed scope.
Disputed Result
The professional believes the work was performed correctly, but the client alleges that the service caused a loss and demands reimbursement or legal action.
Two Different Types of Liability Protection
General Liability vs. Professional Liability
These policies protect against different types of business claims. A professional services business may need both.
General Liability
Physical Injury & Property Damage
General liability generally focuses on qualifying third-party bodily injury, physical property damage, and certain personal or advertising injury claims.
Professional Liability
Professional Services & Financial Harm
Professional liability generally focuses on allegations connected to advice, recommendations, records, designs, decisions, or specialized services.
Coverage for Businesses Built on Knowledge and Expertise
Who Should Consider Professional Liability Insurance?
A business should consider professional liability when customers rely on its expertise, recommendations, records, designs, evaluations, decisions, or specialized services. The appropriate policy depends on the profession and the type of financial harm a client could allege.

Timing Can Matter
Understanding Claims-Made Coverage
Many professional liability policies are written on a claims-made basis. Coverage can depend on when the professional service occurred, when the claim was first made, when it was reported, and whether the service occurred after the applicable retroactive date.
Policy Must Be Active
The policy generally must be active when a qualifying claim is first made and reported, subject to policy terms and any applicable reporting period.
Retroactive Date Matters
Professional services performed before the approved retroactive date may not qualify for coverage.
Report Potential Claims Promptly
Complaints, demand letters, threats, reimbursement requests, legal notices, or other circumstances that may become claims should be reported according to policy instructions.
Protect the History of Your Professional Services
Retroactive Dates, Prior Acts & Continuous Coverage
A professional claim may arise months or years after the work was performed. Policy continuity and prior-work protection should be reviewed carefully before replacing or canceling coverage.
Retroactive Date
Generally identifies the earliest date after which qualifying professional services may potentially be covered under a claims-made policy.
Prior-Acts Coverage
May help protect qualifying professional services performed before the current policy began but after the approved retroactive date.
Extended Reporting
May provide additional time to report certain claims after a claims-made policy ends, subject to applicable policy provisions.
Continuous Coverage
Changing carriers, canceling a policy, or creating a coverage gap may affect protection for prior professional services.
Understand the Policy Structure
Limits, Deductibles & Defense Costs
Each Claim Limit
Generally represents the maximum available for one qualifying covered claim, subject to policy provisions.
Aggregate Limit
Generally represents the maximum available for covered claims during the applicable policy period.
Deductible or Retention
The insured may be responsible for a specified amount before qualifying policy payments apply.
Defense Inside the Limit
On some policies, legal-defense expenses may reduce the amount remaining for settlements or judgments.
Professional Liability Does Not Replace Every Business Policy
Other Coverage May Still Be Needed
