Thompson Coburn LLP data breach class action settlement

What Is This Settlement About?

Thompson Coburn LLP, a national law firm, has agreed to a $7,500,000 class action settlement to resolve litigation over a May 2024 data breach. The case is Salazar et al. v. Thompson Coburn LLP, Case No. 2622-CC00320, in the Circuit Court of the City of St. Louis, Missouri.

According to the lawsuit, an unauthorized party gained access to Thompson Coburn's network in a targeted cyberattack in May 2024 and may have obtained personal information held in the firm's systems. The complaint alleges the firm failed to adequately protect that information. Thompson Coburn denies the allegations and any wrongdoing, and no court has found that the firm did anything wrong. The parties agreed to settle to avoid the cost and risk of continued litigation.

What Happened?

Thompson Coburn experienced a targeted cyberattack on its network in May 2024. A forensic investigation determined that an unauthorized actor may have accessed files containing personal information, and the firm later began notifying affected individuals, with notice letters going out in late 2024.

According to court filings, the settlement covers a class of roughly 377,000 individuals. The information involved varied by person and may have included names, addresses, Social Security numbers, and other personal identifiers contained in the firm's files. If you received a notice letter from Thompson Coburn about this incident, your information was among the data the firm identified as potentially affected.

Who Qualifies?

The settlement class includes individuals in the United States who were sent notice that their personal information was involved in the May 2024 Thompson Coburn data breach. In practical terms, if Thompson Coburn mailed or emailed you a breach notice about this incident, you are a class member and may file a claim.

You will need the Login ID and PIN printed on your notice to log in to the claim portal, so keep that notice handy. If you believe you were affected but cannot locate your Login ID or PIN, you can request help through the official settlement website's contact page.

How Much Can You Get?

The settlement lets eligible class members choose one of two cash options, and all class members may add credit monitoring.

Documented out-of-pocket losses (up to $5,000). You can submit documentation to claim up to $5,000 for out-of-pocket losses fairly traceable to the breach. These can include unreimbursed fraud or identity-theft losses, fees for credit reports, credit monitoring, or freezing and unfreezing your credit, the cost of replacing identification documents, notary and postage costs, and similar expenses. You must provide records showing the loss and that it was connected to the breach.

Alternative cash payment (estimated ~$150). If you do not want to gather loss documentation, you can instead claim a flat alternative cash payment. Court filings estimate this at roughly $150, but the amount is subject to pro rata adjustment — it can rise or fall depending on how many class members file and the funds remaining. You choose this option or the documented-loss option, not both.

Credit monitoring. Class members may also enroll in three years of credit monitoring to help watch for misuse of their information. Check the official settlement website for enrollment details.

Is Proof Required?

Yes. Filing online requires you to enter the Login ID and PIN printed on the notice Thompson Coburn sent you, so the page is marked proof required. A claimant who never received a notice, or who discarded it, cannot file online without first requesting that information through the official settlement website.

The alternative cash payment does not require you to document any losses, but it still requires the Login ID and PIN from your notice. The up-to-$5,000 option additionally requires supporting documentation — receipts, bank or credit card statements, or similar records — showing the loss and that it was tied to the breach.
