Protect the Advice and Services Behind Your Business

Coverage for businesses and professionals facing claims involving mistakes, missed deadlines, incorrect advice, service failures, professional negligence, and financial harm.

Coverage for Professional Services

What Is Professional Liability Insurance?

Errors

Omissions

A client claims that professional recommendations caused lost revenue, unnecessary expenses, or business interruption.

Important Information Is Omitted

A client alleges that documents, reports, instructions, or professional advice failed to include an important requirement.

Two Different Types of Business Liability

General Liability vs. Professional Liability

General Liability

Physical Injuries and Property Damage

General liability generally focuses on covered bodily injury, physical property damage, and certain personal or advertising injury claims.

A customer slips and falls

An employee damages customer property

A product causes physical injury

A visitor is injured at the office

Professional Liability

Professional Mistakes and Financial Harm

Professional liability generally focuses on claims arising from advice, recommendations, designs, records, or specialized services.

Incorrect professional advice

A missed filing or deadline

Incomplete professional services

Alleged financial loss

One Organization Can Have Several Liability Exposures

These Policies Protect Different Responsibilities

A professional services business may need more than one liability policy because client claims, employee claims, management claims, and malpractice claims arise from different relationships.

A Client Questions the Service

Professional liability or Errors & Omissions may apply when a client alleges that advice or services caused financial harm.

An Employee Questions the Workplace

Employment Practices Liability may apply to covered allegations involving hiring, termination, discrimination, harassment, or retaliation.

An Owner Questions Leadership

Directors & Officers insurance may apply to covered allegations involving management decisions, governance, or organizational leadership.

A Patient Questions the Care

Malpractice insurance may apply to covered allegations involving professional healthcare treatment, evaluation, or patient services.

Professional reviewing policy dates, prior work, claim reporting requirements, and coverage continuity.

Timing Can Affect Coverage

Understanding Claims-Made Coverage

Many professional liability policies are written on a claims-made basis. Coverage can depend on when the professional work occurred and when the claim is first made and reported.

The Policy Must Be Active

The policy generally must be active when the claim is first made, subject to its terms and any available reporting period.

The Work Must Follow the Retroactive Date

Professional services performed before the policy’s retroactive date may not be covered.

Report Potential Claims Promptly

Demand letters, complaints, threats, requests for reimbursement, and circumstances that may become claims should be reported according to the policy instructions.

Protect the History of the Professional Practice

Retroactive Dates and Extended Reporting

Maintaining continuous coverage can be important because a professional claim may arise months or years after the service was performed.

When replacing or canceling a professional liability policy, review continuity, prior acts, retroactive dates, and extended-reporting options before making changes.

Retroactive Date

The earliest date after which covered professional services may qualify for protection under a claims-made policy.

Prior-Acts Coverage

May provide protection for qualifying services performed before the current policy began but after the approved retroactive date.

Extended Reporting Period

May allow additional time to report certain claims after a claims-made policy ends, subject to the policy terms.

Continuous Coverage

Gaps or changes in coverage may affect protection for past services and should be reviewed carefully.

The Cost of Defense Can Reduce Available Limits

How Legal Defense May Affect the Policy

Some professional liability policies include defense expenses within the policy limit. Attorney fees and other defense costs may reduce the amount remaining for a settlement or judgment.

Defense Inside the Limit

Covered legal-defense expenses reduce the available policy limit as they are paid.

Defense Outside the Limit

Certain policies may provide defense expenses in addition to the liability limit, subject to policy terms.

Review Before Selecting a Limit

A limit that appears adequate may provide less settlement protection when defense expenses are included within it.

Select Coverage Around the Professional Exposure

Limits, Deductibles, and Contract Requirements

The appropriate structure depends on revenue, services, clients, contracts, project values, past work, and the size of a possible financial claim.

Each Claim Limit

The maximum amount available for one covered professional liability claim, subject to policy terms.

Aggregate Limit

The maximum amount the policy may pay for covered claims during the policy period.

Deductible or Retention

The amount the insured may be responsible for before the policy responds to covered expenses.

Client Requirements

Contracts may require specific limits, policy wording, additional parties, or continuation of coverage after services end.

Project Size

Higher-value projects and clients may create larger potential financial-loss allegations.

Excess Professional Liability

Additional limits may be available when the primary professional liability policy does not meet contractual or risk-management needs.

Clear Expectations Can Help Reduce Disputes

Professional Contracts and Documentation

Written agreements, client approvals, complete records, quality-control procedures, and documented communication can help reduce misunderstandings.

Define the Scope of Services

Clearly explain what the professional will provide, what is not included, and what the client must provide.

Document Changes

Record changes to deadlines, services, fees, project specifications, responsibilities, and client instructions.

Keep Client Approvals

Maintain written confirmation of important decisions, recommendations, warnings, approvals, and completed work.

Report Problems Early

Contact the insurance carrier when a complaint, demand, threat, refund request, or potential claim is received.

Professional Liability Does Not Replace Every Policy

Other Business Coverage May Be Needed

Professional liability focuses on professional services. Physical injuries, property, vehicles, data, employees, and leadership claims may require separate coverage.

General Liability

May address covered third-party bodily injury, physical property damage, and certain personal or advertising injury claims.

Cyber Insurance

May address data breaches, ransomware, computer interruption, privacy claims, and certain electronic fraud.

Commercial Property

May protect buildings, equipment, furniture, computers, records, inventory, and other business property.

Workers’ Compensation

May provide qualifying benefits for employees experiencing work-related injuries or occupational illnesses.

Commercial Auto

Business-owned, rented, leased, or regularly used vehicles generally require commercial auto insurance.

Crime and Fidelity

Employee theft, forgery, fraudulent payments, or theft of client funds may require crime or fidelity coverage.
