First 48 Hours: What to Do When a Claim Is Filed

Notify your insurer immediately

Call your broker or insurer's claims hotline. Most policies require prompt notice, and delayed notification can jeopardize your coverage.

Do not admit fault or apologize

Any admission can be used against you. Even saying 'I am sorry this happened' can be interpreted as accepting responsibility.

Do not discuss the claim with the complainant

All communication should go through your insurer's assigned defense counsel. Direct contact can complicate the defense.

Preserve all relevant documents

Gather and secure all contracts, emails, work product, notes, and correspondence related to the engagement. Do not alter or destroy anything.

Document your recollection

Write down everything you remember about the engagement while it is fresh. Include dates, conversations, decisions made, and the reasoning behind them.

Cooperate with assigned defense counsel

Your insurer will assign an attorney experienced in professional liability defense. Provide them with everything they need and follow their guidance.

FAQ

What is the average cost of defending a professional liability claim?

The average defense cost for a professional liability claim is $35,000-$75,000, even for claims that are ultimately dismissed or settled without payment. This includes attorney fees, expert witnesses, document review, and court costs. Complex claims involving multiple parties or large damages can exceed $100,000 in defense costs alone. Your E&O policy covers these defense costs, which is one of the most valuable aspects of the coverage.

How long does a professional liability claim take to resolve?

The average professional liability claim takes 12-24 months to resolve. Simple claims with clear facts may settle in 6-9 months. Complex claims involving multiple parties, large damages, or disputed facts can take 3-5 years. During this time, your insurer manages the defense and you continue to practice (unless the claim results in a licensing action). The extended timeline is one reason maintaining continuous coverage is critical.

What should I do when I receive a professional liability claim?

First, notify your insurer immediately. Most policies require prompt notice, and delayed notification can jeopardize your coverage. Do not admit fault, apologize, or discuss the claim with the complainant. Do not destroy or alter any documents related to the work in question. Gather and preserve all relevant records, communications, and work product. Your insurer will assign defense counsel and guide you through the process.
