Abigail R. Brown is a member of Parsons Behle & Latimer’s environmental and natural resources team and the firm’s water law practice groups. She has more than a decade of experience representing a diverse range of water users, from small individual family farms to large irrigation districts, in water law and real property matters. Ms. Brown holds an L.L.M. in Water and Environmental Law from McGeorge School of Law, where she focused on contemporary water law and environmental issues facing the greater Intermountain West region.

In her water law practice, Ms. Brown represents water users through all stages of water rights adjudication proceedings in the Montana Water Court, water rights distribution and enforcement conflicts in state district courts and administrative permitting in state agencies. Ms. Brown also represents clients in a wide range of transactional matters, including water rights due diligence investigations for clients’ existing water portfolios or for clients who are purchasing water rights or real property with appurtenant water rights.

As a conflict resolution professional, Ms. Brown offers mediation, facilitation and conflict coaching services to water users as an alternative to litigation or in connection with potential settlement discussions in existing litigation. She is a conflict resolution facilitator, often partnering with other organizations to facilitate community dialogues and stakeholder meetings to address business, organizational, community and local government conflicts.

Outside of her legal career, Ms. Brown and her spouse Collin spend their time adventuring with their two little boys and seeking out the best creek-side campsites in the Intermountain West.
