A Checklist for Internal Response When a Professional Liability Insurance (Errors & Omissions) Claim Arises

When a Professional Liability (Errors & Omissions, “E&O”) claim arises, the first 72 hours determine control over narrative, evidence, and cost exposure. This checklist is built for U.S.-based firms — with practical, location-specific guidance (New York City, Los Angeles, Chicago, Houston) — and is tailored to claims that implicate your E&O policy. It focuses on immediate containment, insurer coordination, litigation-readiness, and cost control.

Why a rapid, documented internal response matters

  • Preserves coverage: Insurers often deny coverage for late notice or spoliation.
  • Controls litigation costs: Early evidence collection and counsel selection reduce defense spend.
  • Minimizes reputational and regulatory fallout: Timely communications protect client relationships and satisfy regulators.

Immediate (0–24 hours) — Contain and Notify

  • Activate the incident response team
    • Roles: Incident Lead (senior manager), Legal Counsel (in-house or retained), IT/Forensics, HR, Communications, Finance.
  • Secure and preserve evidence (litigation hold)
    • Implement a written litigation hold across email, project files, contracts, cloud storage, Slack, and employee devices.
    • Disable auto-deletion and preserve metadata.
  • Log the event
    • Create an incident file: date/time discovered, reporting person, client details, alleged error, impacted deliverables.
  • Notify your insurer per policy terms
    • Follow your policy’s notice provisions. Even a preliminary notice satisfies many policies and avoids late-notice exposure. For the insurer’s expectations and timeline, see Step-by-Step: Reporting a Claim….
  • Freeze external communications
    • Authorize one spokesperson. Do not admit fault or discuss details with the claimant or media.

Short Term (24–72 hours) — Triage, Assess, and Plan

  • Triage severity and exposure
    • Estimate potential damages (client compensatory losses, statutory fines, remediation costs). Use past claims or market benchmarks to inform initial reserves.
  • Assign counsel strategy
  • Collect critical documents
    • Contracts and SOWs, change orders, emails, proposals, meeting notes, quality control records, client approvals, invoices, project deliverables.
  • Forensic & technical preservation
    • If software/code or data integrity is disputed, engage digital forensics immediately (log snapshots, backups).
  • Stakeholder communication plan
    • Internal memo to executives, client outreach script (if approved by counsel/insurer), regulator reporting checklist if applicable (e.g., SEC, state boards).

Ongoing (Week 1–4) — Defense Preparation & Cost Controls

  • Formalize documentation and privilege
    • Ensure attorney-client privilege on internal notes created for defense. Maintain privilege logs.
  • Estimate defense budget and reserves
    • Establish a claims reserve and reporting cadence to CFO and insurer. Track billing against budget.
  • Engage subject-matter experts
    • Retain experts early for technical rebuttal or remediation cost validation.
  • Consider early ADR/settlement
  • Maintain client relationships
    • Where appropriate and counsel-approved, offer remediation or mitigation to preserve client trust and limit statutory damages.

Evidence & Preservation Checklist (must-haves)

  • Contracts, SOWs, change orders
  • Client sign-offs and acceptance emails
  • Project timelines and QA logs
  • Source code snapshots / change history (if relevant)
  • Backups and system logs (with timestamps)
  • Invoices, billing records, payment approvals
  • Employee statements and interview notes (privileged)

Typical E&O Cost Benchmarks (U.S. market, 2025 estimates)

Below are market-based premium ranges to help you anticipate insurer involvement and retention costs. Premiums vary by profession, revenue, claims history, location, and limit structure.

Profession / Risk Typical U.S. Premium Range (annual) Example U.S. Cities
Independent consultants / small tech firms $600 – $3,000 per year for $1M/$1M New York City, Los Angeles
Small healthcare or legal practices $2,000 – $10,000 per year Chicago, Houston
Architects / Engineers / High-risk design firms $5,000 – $25,000+ per year NYC, San Francisco
Mid-market tech/SaaS with high exposure $3,000 – $50,000+ depending on limits Austin, Seattle

Note: specialist underwriters such as Chubb, CNA, and AIG price higher for large limits and complex exposures; high-limit coverage (multi-million) can cost tens of thousands annually.

Financial & Negotiation Tips (practice in NYC / LA / Chicago / Houston)

  • Understand your retention: Typical retentions range from $1,000 to $25,000 depending on industry and policy.
  • Negotiate defense counsel rates: For multi-jurisdictional matters (e.g., NYC vs. LA), require insurer approval of hourly caps or blended rates.
  • Reserve coverage for settlements: If insurer agrees to mediation, request advance approval for settlement authority up to a defined limit to accelerate closure.

Post-Claim: Lessons, Remediation, and Program Updates

  • Conduct a post-mortem: root cause, policy gaps, training needs.
  • Update policies: contract language, limitation of liability clauses, quality control processes.
  • Renew insurance strategically: shop carriers (Hiscox, The Hartford, CNA, Chubb) and compare limits, retentions, and defense terms.

Final checklist (quick reference)

  • Activate response team and log event
  • Preserve evidence and issue litigation hold
  • Notify insurer per policy provisions (document proof of notice)
  • Retain counsel and forensic experts (if needed)
  • Establish budget and claims reserve; track costs weekly
  • Limit communications; centralize spokespersons
  • Evaluate early settlement vs trial with counsel & insurer
  • Conduct post-claim remediation and update risk controls
