Does Maryland have Jurisdiction for your divorce?
There is a one year requirement if the grounds for the divorce occurred outside the state of Maryland, otherwise if either spouse is a resident of the state of Maryland, he or she may file in the county in which either spouse resides. If you are filing for divorce under the grounds of insanity, the residency requirement is increased to two years.
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 Maryland address in the county where you are filing your divorce. Maryland civilian residents living overseas may file in Maryland if they have maintained their residency in Maryland.
