In re Mason, Justin Lamar, 2025PR00041
Disposition Disbarment
Effective Date of Disposition 11/19/2025
End Date of Disposition No disposition end date scheduled at this time. Discipline continues until further order of the Court.
Definition of Disposition Disbarment is a determination that the lawyer has engaged in misconduct warranting the most serious sanction. The disbarred lawyer is not authorized to practice law during the period of the disbarment and may not return to the practice of law unless and until he or she has demonstrated his or her rehabilitation, good character, and current knowledge of the law in a subsequent reinstatement case, which may not be filed until five years after the effective date of the disbarment.
Case Summary Mr. Mason was licensed in Illinois in 2012 and in Missouri in 2010. In March 2025, the Supreme Court of Missouri disbarred him for engaging in trust account mismanagement, including not reconciling his trust accounts, not disbursing payments to clients and third parties, and taking client funds for his own personal use. The Illinois Supreme Court imposed reciprocal discipline and disbarred him.
