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
  • Coordinate with insurer to confirm defense counsel appointment or selection process (managed vs. independent counsel). Guidance: How Defense Counsel Are Selected and Managed….
• 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
  • Analyze cost-to-trial vs settlement. See strategic decision criteria in Settlement vs Trial: Decision Criteria for Professional Liability Insurance (Errors & Omissions) Claims (internal resource).
• 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)

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
