Unclaimed property (sometimes referred to as abandoned) refers to accounts in financial institutions that have had no activity generated or contact with the owner for an extended period. Every state maintains unclaimed property laws and programs whose purpose is to protect consumers by ensuring money owed to them is returned to them, rather than remaining permanently with the financial institutions.
To avoid having an account classified as abandoned and the assets turned over to the state in which the client resides, clients are advised to log into their account regularly to establish the account as active. Please contact your local IBKR Client Service Center if you need assistance with the log in process.
To reclaim your assets, you will need to go directly to the state in which you reside. For clients who reside outside the U.S. the funds will be remitted to IBKR's state of incorporation, Connecticut. For more information, please visit The National Association of Unclaimed Property Administrators website which contains links to each of the individual states' database.
