Does Nebraska have Jurisdiction for your divorce?
Nebraska law requires that no action for dissolution of marriage may be brought unless at least one of the parties has had actual residence in this state with a bona fide intention of making this state his or her permanent home for at least one year prior to the filing of the petition, or unless the marriage was solemnized in this state and either party has resided in this state from the time of marriage to filing the petition. All dissolution of marriage proceedings shall be brought in the district court of the county in which one of the parties resides.
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 a Nebraska address in the county where you are filing your divorce. Nebraska civilian residents living overseas may file in Nebraska if they have maintained their residency in Nebraska.
