The Prosecuting Attorney protects the rights, safety and security of all persons within the boundaries of the County through the enforcement of state law as mandated by State Constitution and Statutes.

The Prosecuting Attorney is an elected official with a four-year term of office, as provided by the Michigan Constitution. Elections occur at the time of the Presidential election, on the partisan ballot. The elected county Prosecuting Attorney is independent of the Michigan Attorney General.

The Prosecuting Attorney’s office is responsible for a wide array of legal functions for the County, including:

  • Act as the Chief Law Enforcement official in the County.
  • Review, authorize and prosecute violations of felony and misdemeanor criminal laws of the State of Michigan and County ordinances committed inside the County
  • Authorize and prosecute felony & misdemeanor juvenile delinquency offenses
  • Represent the County in criminal matters before the District and Circuit Courts; juvenile delinquency, parental neglect and miscellaneous probate matters in the Family Court, and appeals in the Court of Appeals and Michigan Supreme Court
  • Advise the Family Independence Agency on child abuse & neglect petitions, and actions to terminate parental rights
  • Attend contested mental health commitment hearings
  • Presides at a monthly Concealed Weapon Permit Board, unless he opts off for the remainder of their term. In that case, the county board appoints a certified firearms instructor to replace the Prosecuting Attorney.
