Where to file
Probate is filed in the county where the person who died last lived. If that was Mason County, this is the court — local forms, e-filing rules, and scheduling vary by county, so confirm with the county probate court. If they last lived in a different county of the same state, the case belongs in that county’s court instead, and one appointment there covers property across the state. If they last lived in another state, the main case belongs there, and property in Mason County generally needs a second, smaller case of its own here (commonly called ancillary probate) — an attorney can confirm which applies.
