People often ask me if they can be divorced in DC if they were married outside DC.
The answer is Yes.
You can file for divorce in DC as long as you have been OR your husband or wife has been a resident of DC for at least six months continuously prior to filing. Only one of you needs to be a resident of DC in order to file.
In addition, you must have been living separate and apart continuously for at least six months if you both agree to the divorce. Otherwise you have to wait to file until you have been separated for one year.
