Claire Wells Hanson


Claire Wells Hanson is a complex commercial litigator focusing on contractual and real estate disputes, securities fraud, and business torts. As the leader of the firm’s Cannabis Litigation Team, she stands out among industry practitioners due to her unique background and skill set. Claire spent more than a decade practicing in the most sophisticated legal markets in the country before she started tackling disputes for cannabis clients. Thus, she is well equipped to handle litigation or arbitration for any business or owners, of any contract or claims.

Claire has vast experience helping clients navigate disputes in nearly every area of the law, including securities, real estate, intellectual property and licensing, trade secrets, restrictive covenants, product liability, defamation, and Constitutional law. Claire applies her experience and litigation know-how in the cannabis industry, by advising marijuana and hemp companies on dispute avoidance and management, defending them against claims, and vindicating their rights.

Claire’s litigation record exemplifies her practical, nimble, and strategic approach to resolving disputes. She has tried cases—and won—in federal and state court. She has argued successfully in the Tenth Circuit Court of Appeals. She’s won many cases and claims on summary judgment and other dispositive motions, avoiding the stress and expense of trial for her clients. And she has a long history of success with alternative dispute resolution measures, including mediation and arbitration.

Claire serves as the Member in Charge of the firm’s Denver office, a newly built-out space just around the corner from Union Station.
