Does Tennessee have Jurisdiction for your divorce?
The spouse filing for the divorce must be a resident of the state at the time the grounds for divorce took place. If the grounds took place outside the state of Tennessee, one of the spouses must be a resident for 6 months prior to filing. The divorce shall be filed in the county in which both spouses reside if they are both residents; or the county in which the respondent resides if he or she is a resident; or the county in which the petitioner 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 an Tennessee address in the county where you are filing your divorce. Tennessee civilian residents living overseas may file in Tennessee if they have maintained their residency in Tennessee.
