MJMS Family Office Services LLC & LLP, operating in the specialized field of wealth management and financial administration, officially reported a data security incident to the Indiana Attorney General on July 14, 2026. This breach stems from an event on January 22, 2026, which compromised the security of clients' private information entrusted to the firm.
The compromised data is extensive and highly sensitive, given the nature of a family office's operations. The incident exposed individuals' Full Name, Social Security Number, Date of Birth, Financial Account Number, Routing Number, Tax Return Information, Direct Deposit Account Details, Investment Portfolio Records, and Home Address. This combination of data can be particularly damaging in the wrong hands.
The exposure of Social Security numbers alongside detailed banking and investment information creates a serious risk. Such data empowers cybercriminals to attempt sophisticated identity theft, initiate unauthorized financial transactions, or target individuals with tailored phishing schemes. For high-net-worth individuals, the breach of investment portfolio records and tax information could also lead to corporate espionage or targeted financial extortion.
Financial institutions like MJMS Family Office Services are held to stringent standards under laws like the Gramm-Leach-Bliley Act (GLBA) to safeguard nonpublic personal information.

This letter is not just an alert; it establishes your formal standing to investigate your legal options and potential claims arising from this security failure.
It is important to carefully review your notification letter from MJMS Family Office Services LLC & LLP. This document should outline the specific details of the breach and the steps the company is taking. However, the letter may not fully explain the long-term risks or your legal rights.
