What can i do about these horrible false accusations with dcfs?

You haven't indicated why you would even HAVE a trial, but if/when you do, you can dispute the claims. Yes, the claims will remain on file, but if you successfully refute them, it will have no impact on your life after that. There is nothing you can do about the charges, anyone can make an accusation, so your best bet is to simply refute them and move on.
