Does Idaho have Jurisdiction for your divorce?
Either the petitioner or the spouse must have been a bona fide resident of this state for six weeks prior to the filing of the complaint, which must be stated in the complaint and proved at the final hearing (Drivers License, etc.).
If you have minor children living with your spouse in another state for over six months then you should consider filing in that state as that court has jurisdiction over the children. Your spouse can waive that jurisdiction in writing.
You should file the divorce in the county where you presently reside, or in the County where your spouse resides, if she lives in another County. You or your spouse must have an Idaho address in the county where you are filing your divorce. Idaho civilian residents living overseas may file in Idaho if they have maintained their residency in Idaho.
