Yes, parties may designate the law of another jurisdiction to govern their agreement. The chosen jurisdiction must have a significant relationship to the agreement or to either party at the time of signing. The choice will not be honored if it conflicts with Colorado’s enforceability rules or fundamental public policy. If no valid choice is made, Colorado law applies, including its choice-of-law rules. This flexibility can be useful for couples with multi-state ties or assets. The governing-law rule is stated in the Colorado statute.
