Whether or not the divorce or annulment would be in the nation in which it's issued? That's something to discuss with a lawyer in that nation.
The difficulty with this sort of thing can arise way down the road when you don't expect it - when your new spouse decides she would rather claim your marriage is bigamous than go through a divorce, or where your heirs argue that your marriage to your new spouse was not valid in order to try to have her excluded from your estate, or in other ways you can't presently imagine. If it were me, I would stay away from a website that on the surface seems to fall into the category of, "If it sounds too good to be true...." And if I were inclined to go that route I would do my due diligence in the nation that would be (supposedly) issuing the divorce or annulment to make sure that it's valid, then taking further steps to domesticate the judgment to try to ensure that it will stand in the event of future challenge. Really, I personally would go through the Maryland courts.
