The general assembly finds and declares that the abstract attorney’s title opinion system promotes land title stability for determining the marketability of land titles and is a public purpose. A public purpose is served by providing, as an adjunct to the abstract attorney’s title opinion system, a low-cost mechanism to provide for additional guaranties of real property titles in Iowa. The title guaranties facilitate mortgage lenders’ participation in the secondary market and add to the integrity of the land-title transfer system in the state.
