The Courts That Hear Cases from Ontario
In Ontario, the Malheur County Circuit Court hears every civil, criminal, family, probate and juvenile case.
A city with a municipal and justice court of its own tries the tickets written under its ordinances.
Divorces go to the Circuit Court, and the file stays with the trial court administrator.
The trial court administrator keeps the files, and a copy of anything in a file comes from that office, under the court's own rules rather than the Oregon Public Records Law.
