Within the Tenth Circuit, states vary in their enforcement of restrictive covenants. Wyoming, Kansas, and New Mexico govern the use of restrictive covenants through common law while Utah, Colorado, and Oklahoma govern through statute. Oklahoma is unique in that it prohibits restrictive covenants through statute. In the other five states, despite the variations in governing authority, many of the factors used are similar given the widely accepted “reasonableness” standard many jurisdictions have adopted as a metric for adjudicating the propriety of such agreements.
