In Colorado, Courts will divide and transfer marital property between spouses equitably in a divorce proceeding, see http://www.awfamilylaw.com/blog/2016/10/marital-property-division-in-colorado.shtml. Prior to the mid-1980's, Colorado along with many states applied the title rule, which was that whomever had title to property would receive that property upon a separation. As a result, trust assets were generally not included in the division of marital property. In the interest of avoiding unfair property distributions, Colorado has expanded the pool of assets Courts must divide to include all assets, regardless of title.
In Colorado, marital property is divided without regard to misconduct or fault. The Court does not necessarily divide property evenly, or 50/50. Colorado Courts consider "all relevant factors" in making the decision of how to divide marital property. The Courts attempt to make divisions based on what is fair for both parties.
