Contractually Assumed Liability: How Professional Liability Insurance (Errors & Omissions) Treats Indemnities

Contract language that shifts risk—indemnities, hold harmless clauses, and contractually assumed liability—can create exposures that exceed a firm’s ordinary professional risk. For US-based professionals and firms (especially in New York City, San Francisco Bay Area, Chicago, Dallas and Los Angeles), understanding how Professional Liability / Errors & Omissions (E&O) insurance treats indemnities is essential to avoid uncovered claims, contract disputes, and unexpected litigation costs.

Quick summary

• Contractually assumed liability means you promise to indemnify or defend another party under a contract.
• Most E&O policies exclude intentional acts, fraud, and punitive damages, and many contain contractual liability exclusions unless an endorsement applies.
• Practical strategies include negotiating contract language, buying endorsements (e.g., contractual liability, additional insured/primary & non-contributory), and using risk-transfer best practices.

What is contractually assumed liability (indemnity) in practice?

Contractually assumed liability typically appears as:

• A promise to indemnify another party for claims arising from your services.
• A requirement to defend and/or hold harmless a client or downstream party.
• Broader obligations that may include liabilities the indemnitee would have had absent your contract.

These clauses are common in:

• Professional service agreements (consultants, architects, engineers)
• Technology contracts (software vendors, SaaS providers)
• Construction subcontracts and design-build agreements

Why it matters: E&O policies are written to protect against negligent acts, errors, or omissions. If your contract requires indemnity for risks not caused by your negligence—or for third-party claims—their coverage may be limited or excluded entirely.

How E&O policies typically treat indemnities

Key policy positions across the market:

• Contractual liability exclusion with exception: Many E&O forms exclude liability assumed by contract but contain an exception for contractual liability that the insured would have had in the absence of the contract (i.e., liabilities that arise from your professional negligence). This exception is narrow.
• Intentional acts and fraud: Indemnities for intentional wrongdoing, fraud, or criminal acts are almost always excluded.
• Defense obligations: Policies can exclude contractual duty to defend other parties. Even when indemnity is covered, the insurer may reimburse damages rather than advance defense costs unless an endorsement says otherwise.
• Primary/non‑contributory & additional insured: Insurers often restrict or price endorsements that make the E&O primary or provide broader defense obligations for other parties.

Practical consequence: A broad indemnity that obligates you for any loss (even without negligence) risks being denied by your E&O carrier.

Typical premium ranges and limits (USA market examples)

E&O pricing varies by profession, revenue, claims history, and location. Representative figures (market examples as of 2024):

Notes:

• A typical small professional firm can expect $1M/$1M limits to cost roughly $500–$2,500/year, depending on profession and location (NYC & San Francisco usually at the higher end).
• Mid‑market and specialty risks (technology, IP exposure, healthcare) often see $2,000–$10,000+ premiums for higher limits and endorsements.

Common contractual problem clauses and insurer responses

• Broad “any and all” indemnities — often declined by E&O carriers unless narrowed.
• Duty to defend or pay attorney fees for the indemnitee — carriers may refuse to advance defense costs without specific endorsement.
• Indemnities for third-party bodily injury or property damage — often excluded under E&O (these exposures may belong to general liability).
• Waiver of subrogation and primary/non-contributory language — insurers will often charge a surcharge or require specific wording.

Negotiation and risk-transfer strategies (practical steps)

• Narrow the indemnity: Limit indemnity to claims “to the extent caused by your negligence” rather than blanket indemnities.
• Add mutual indemnities: Where possible, convert one-way indemnities to mutual obligations.
• Limit scope and cap liability: Add reasonable monetary caps tied to contract value or insurance limits.
• Request endorsements: Ask for a contractual liability endorsement, primary & non‑contributory wording, or a defense‑costs advance endorsement if essential.
• Buy appropriate limits: Higher limits ($2M–$5M) may be necessary in high-risk jurisdictions (e.g., NYC, San Francisco).
• Contractual risk allocation: Push certain risks to parties better able to control them (subcontractors, vendors) and require their insurance.

Endorsements and policy language to request

• “Contractual Liability” coverage endorsement (narrow wording that extends coverage to certain contractual indemnities).
• “Duty to Defend” advance endorsement (insurer agrees to pay defense costs as incurred).
• “Non‑contributory” and “Primary” endorsements (if you agree to primary coverage).
• “Waiver of Subrogation” endorsement (if the client requires waiver).

If a claim arises from an indemnity clause — immediate steps

1. Notify your insurer promptly with full contract and claim details.
2. Preserve all documents and communications relating to the contract and the incident.
3. Engage coverage counsel experienced with E&O indemnity disputes if the insurer denies coverage.
4. Consider tendering defense of the indemnitee only after insurer approval or seeking a defense cost advance endorsement.
5. Negotiate resolution (global settlements that allocate fault can preserve coverage if structured correctly).

Bottom line — practical checklist for US firms (NYC, SF Bay Area, Chicago, Dallas, Los Angeles)

• Review all client contracts for broad indemnities and defense obligations.
• Obtain written confirmation from brokers/insurers about how your E&O responds to the exact contract language.
• Negotiate to limit indemnities to negligence, add caps, or mutualize obligations.
• Buy endorsements if your clients insist on onerous contractual terms.
• Budget for higher premiums in high‑claim jurisdictions; expect $500–$2,500+ for typical small-firm E&O and significantly more for specialty risks.
