Justin Munn is a dedicated attorney with over 25 years of experience, currently practicing at Smakal Munn, P.C., in Tulsa, Oklahoma. His proficiency lies in handling complex and contested family law cases, encompassing areas such as:

  • Domestic disputes
  • Parenting coordination
  • Probate matters
  • Guardianships
  • Adoptions

In addition to his family law focus, Mr. Munn excels in business and commercial law, construction law, trusts, wills, probate and estate administration, and estate planning. His extensive legal background positions him as a versatile practitioner capable of addressing a broad spectrum of legal needs.

Admitted to practice in all Oklahoma state and administrative courts, the U.S. District Court for the Northern District of Oklahoma, and the Cherokee Nation and Creek Nation Tribal Courts, Mr. Munn maintains a robust civil litigation portfolio. His focus remains steadfast on family, domestic, probate and estate planning matters. He is a certified family and domestic mediator, having completed rigorous family law mediation training with the Mediation Institute and the Tulsa County Early Settlement program. He also actively imparts his knowledge on alternative dispute resolution, having presented on the subject to organizations such as the American Subcontractors Association of Oklahoma and the Oklahoma Bar Association's continuing legal education program.

Mr. Munn obtained his J.D. from Northwestern School of Law at Lewis & Clark College in Portland, Oregon, in 1998. While there, he achieved a certificate in Environmental and Natural Resources Law. In law school, he served as an administrative board member of the Public Interest Law Project and was a valuable member of the law school’s Regional Moot Court Negotiations Competition team. Prior to his legal studies, he graduated from Southern Methodist University in Dallas, Texas, with a B.A. degree in geology and anthropology. Additionally, he actively participated in Archaeological and Geological Field Studies in New Mexico, Arizona and Barbados.

An active member of the legal community, Mr. Munn contributes to various organizations, including the Oklahoma Bar Association and its ADR Section (holding the position of co-secretary), the Tulsa County Bar Association with involvement in its Fee Arbitration & Grievance Committees, the Creek County Bar Association and the Cherokee Nation Bar Association. Moreover, he serves on the Cascia Hall Preparatory School Alumni Board of Directors as a treasurer.

Mr. Munn functions as a parenting coordinator concentrating on domestic litigation cases and has contributed to the legal discourse through a published opinion, specifically in Fultz v. Smith (2004 OK CIV APP 64, 97 P.3d 651, 2004), pertaining to the responsibilities of parenting coordinators. He also works as a distinguished panel member at Dispute Resolution Consultants, where he applies his knowledge as a mediator in family and domestic legal matters.

Acknowledging his dedication to serving the community through legal assistance, the Legal Services of Eastern Oklahoma gave Mr. Munn the Volunteer for Justice Award. Furthermore, in 2013, Tulsa Business & Legal News recognized him as a Power Attorney. His exceptional contributions have garnered further acclaim from the Best Lawyers.
