if you were married in Scotland and now one of the spouses no longer lives there do they need to go back to get a divorce?
No.
Where you were married does not matter. Follow the divorce laws in your current state of residence.
A license does not mean one got married. You can file for divorce at your current state of residence.
Yes, I did it in Texas
You can file for divorce in the Bahamas only.
File for divorce in the jurisdiction of your current address.
If you are legally in the US, you file in the state where you live. You do the same thing as a citizen of the US would do.
Did you get a marriage certificate? If you got one then yes.. welcome to the club.. you have to get divorced
In the US you file for divorce in the state in which you are a resident, regardless of if you were married in that state or not
Usually a person files for divorce in their current resident state. If your Mexican marriage is recognized as legal by the U.S. then you will have to file in America if that is where you are living
They cn file for a divorce in the state where they presently reside.
It would probably be easiest in the country where you were married. Also, if everybody is in agreement, get an "uncontested" divorce. They are much easier and cheaper.
