You don't have to bother speculating. Federal courts do not, and never will, decide divorce actions.
Trial by jury is a right in the lower courts that does not apply in appeals courts or the Supreme Court. The jury makes findings of fact and fact is no longer in issue on appeal.
Hopefully you had proof that this woman's husband was cheating. If there is no truth to the accusations; the divorce happened then yes, her ex husband could have sued you because it's 'defimation of character' and you ruined not only his marriage but his reputation' and the courts would decide. However, if the husband did cheat and you witnessed it then you could be called in as a witness, but this generally does not happen.
TrialsUS District Courts are the trial courts of the Judicial Branch of the Federal government. Appellate courts, like the US Court of Appeals Circuit Court and the US Supreme Court, only consider the question or questions raised on appeal and do not retry the case or make determinations of guilt.
Federal District Courts, Courts of Appeals and even Bankruptcy Courts have all ruled on the issue of same-sex marriage. All that remains is the US Supreme Court. This is scheduled to happen by the end of June 2013.
There are two main systems, Judicial, dealing with laws, and civil, dealing with codes and mainly civil matters. Breaking a law , such as stealing a car, would go to the judicial system. Claims that a company was negligent and allowed an injury to happen would go to civil court. An auto accident insurance claim might go either way, depending if the defendant was supposedly breaking any laws as said time of incident.
If there would be no courts then there would be injustice around our society
divorce
You can marry in this amount of time but from what I know, divorce takes months to happen.
then no divorce should happen because the paper is not valid
Yes, of course (assuming that by "moves in with" you mean "has sex with"). If you haven't divorced your spouse, you are still married, wherever you happen to live, and whatever terms you happen to be on. Indeed, in the Roman Catholic tradition, divorce doesn't exist - you may have your marriage dissolved in the civil courts, but you still remain married in the eyes of God, and it's still adulterous if you take up with someone else. I shall not disguise my contempt for the practice of obtaining an annulment after many years of marriage as a "Catholic divorce".
