An IOLTA account is an Interest on Lawyers' Trust Account. Most lawyers must have IOLTA accounts in order to hold client funds because lawyers may not deposit a client's money with their own money. IOLTA accounts are interest-bearing checking accounts. The interest on all IOLTA accounts in a state is pooled together, and is then used to help low income individuals afford legal help. For more information about IOLTA checking accounts, contact a Relationship Banker at 630-773-0350.
