The Colorado Lawyer Trust Account Foundation (COLTAF) administers Colorado's Interest on Lawyer Trust Accounts (IOLTA) program. This program is an innovative partnership between the legal community and the banking community, whereby the interest on lawyers' pooled trust accounts is used to make grants to improve access to civil justice statewide. IOLTA programs operate in all fifty states and in the District of Columbia, and are an increasingly critical piece of the funding picture for civil legal services for the poor.

COLTAF was established in 1982 by the Colorado Supreme Court, in response to severe cuts in federal funding for legal services. From 1982 to through 2006, COLTAF has made grants in excess of 19 million dollars. Approximately 80% of these funds have gone to Colorado's federally-funded legal services programs. The other 20% have gone to bar-sponsored pro-bono programs, domestic violence programs, and other justice-related organizations.

COLTAF's only source of revenue is the interest earned on COLTAF accounts at banks across the state. Therefore COLTAF's ability to provide resources for a vital community purpose is entirely dependent on banks waiving fees on COLTAF accounts and paying strong COLTAF interest rates. The vast majority of Colorado banks waive fees. In addition to waiving fees, COLTAF's Leadership Banks pay flat or weighted interest rates on their COLTAF accounts of 2.00% or above. Lawyers can support COLTAF by maintaining their COLTAF accounts at one of the Leadership Banks.
