The IOLTA Program (Interest On Lawyers Trust Accounts) began on a voluntary basis in 1983. In 1988, the Oregon State Bar members voted to make the IOLTA program mandatory, and the Oregon Supreme Court approved the necessary rule changes, effective May 1, 1989.

Since the IOLTA program became mandatory in 1989, the Oregon Law Foundation has awarded over $17,000,000 for charitable, law related purposes. The existence of IOLTA has allowed the Oregon Law Foundation to fund programs that provide civil legal services to people of lesser means helping to create greater access to justice in Oregon.
