An uncontested divorce is one in which both you and your spouse agree to the divorce and there are no issues in dispute.
Does it matter if you or your spouse files for the divorce? The answer is no.
Either one of you may file, however, the person who files (the plaintiff) will have to attend a short hearing.
Your spouse (the defendant) does not usually need to appear unless he or she is requesting a return to a former name or if he or she is the DC resident and you do not live in DC.
