Does Texas have Jurisdiction for your divorce?
A suit for divorce may not be maintained in this state unless at the time the suit is filed either the petitioner or the respondent has been: (1) a domiciliary of this state for the preceding six-month period; and (2) a resident of the county in which the suit is filed for the preceding 90-day period.
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 Texas address in the county where you are filing your divorce. Texas civilian residents living overseas may file in Texas if they have maintained their residency in Texas.
