For business owners whose contract wants the client named as additional insured on all policies: usually not on Professional Liability (E&O). Many contracts ask for proof of your limits instead.
The short answer
- Usually not for full additional insured status. Professional Liability (E&O) often responds to claims a client brings against you, so naming that client as a full insured is usually a poor fit.
- Many contracts only ask for proof of a limit. A certificate of insurance (a one-page summary of your coverage) shows your Professional Liability limits, and clients often use it as that proof.
- Some policy forms may add a client for vicarious liability only (explained below). Check your policy and contract before you sign.
What does an additional insured requirement mean for Professional Liability?
An additional insured is a person or company, other than you, that your policy also protects. Clients often ask so your insurance helps defend them if someone sues them over something you did. Here is how the request often shows up:
Illustrative contract wording
Consultant shall maintain Commercial General Liability, Automobile Liability, Umbrella Liability and Professional Liability insurance as set out in Exhibit C. Client, its affiliates, officers and employees shall be named as additional insureds on all policies required under this Agreement, except Workers' Compensation and Professional Liability.
Illustrative example only. Actual contract wording varies.
- Where it usually applies: General Liability (injury and property damage claims), commercial auto (vehicle coverage) and umbrella policies (extra limits that sit on top of other policies). These policies often allow additional insureds.
- Where it usually does not: Professional Liability and workers' compensation (which covers employee injuries). Many contracts already list these as exceptions, like the example above.
- What to read closely: the full insurance section and any exhibit it points to. See MSA insurance requirements for a walk-through.
Who asks for additional insured status on Professional Liability?
Almost any client may ask, often through a standard form that applies one rule to every vendor. It is common from:
- Large companies whose vendor insurance schedule lists additional insured for every policy type, even when the rule was written for General Liability
- Property managers and real estate owners
- Government agencies and public entities
- Prime contractors passing terms down to you
Why can't a client usually be added as additional insured on Professional Liability?
General Liability covers claims from outsiders, like a visitor who trips at a job site. If the client gets pulled into that lawsuit, additional insured status on your General Liability policy can help defend them. See Professional Liability vs. General Liability.
Professional Liability is built for a different kind of claim. It usually responds when someone says your mistake, missed deadline or bad advice caused them a financial loss. Often, that someone is the client. Adding the person who sues you as an insured on the policy that defends you does not fit how this coverage is usually built.
Many policies also have an insured-versus-insured exclusion. It removes coverage when one insured sues another. If the client became a full insured, this exclusion could block the very claim the policy exists to cover.
Some Professional Liability forms, such as Miscellaneous E&O (general professional services) or Technology E&O, may allow a client to be added for vicarious liability only. Vicarious liability means the client is held responsible for someone else's actions, here a claim against the client that is caused by your work. It is not full additional insured status, and it does not cover the client's own claims against you. Availability varies by form and type of work, so check the wording before you sign.
Most clients just want proof you carry the limit they asked for. A certificate can show your carrier, policy number, dates and limits. See certificates of insurance for Professional Liability for what a clean certificate usually includes.
What will underwriters ask for?
- The full insurance section of the contract and any exhibits, so the quote matches the requirement
- Your current policy, including its retroactive date (the earliest work date it covers)
- A short description of your services, your revenue and your largest clients
- Loss runs, which are reports showing your past claims
Additional insured requests usually land on your General Liability, auto and umbrella policies, so check those separately.
What affects the cost?
These factors often drive price:
- The services you provide and your revenue
- The limit the contract requires (see Professional Liability limits explained)
- Your claims history
- Your retention, the amount you pay on a claim before the policy pays, similar to a deductible
- How defense costs are paid. Many policies pay them inside the limit, so legal fees reduce what is left for a settlement.
Good to know
Remember the trigger. Professional Liability is almost always claims-made: it covers claims made and reported while the policy is active, for work done on or after the retroactive date. Keep coverage in force as long as the contract asks.
Frequently asked questions
Can a certificate say the client is additional insured on my Professional Liability?
A certificate does not change your coverage. It should only show what your policy provides. If the policy does not include the client as an additional insured, the certificate should not say it does.
What if my contract says "all policies" with no exceptions?
That wording may ask for more than a Professional Liability policy usually allows. Have the clause reviewed against your current policy before you sign. Morrow can review both and request quotes for the Professional Liability limit the contract asks for.
Does adding a client as additional insured on General Liability also cover them for my professional mistakes?
Usually not. General Liability often excludes professional services, and additional insured status there usually applies to injury and property damage claims, not financial losses from your advice.
How do I show a client my Professional Liability limits?
Check the limit the contract names, then confirm with the client that your Professional Liability limit meets it. A certificate of insurance shows your per claim limit (the most the policy pays for one claim) and your aggregate limit (the most it pays in total during the policy period).
