A conflict of interest could arise for number of different reasons, but usually it is due to the fact that an attorney or a firm has knowledge about opposing parties that it would not normally be entitled to if she/ he or it were representing only one of the parties. I am not aware off any rule that forces the attorney/firm to disclose information regarding the conflict, but I would think a general description would be available. Something like, "your husband came in for a consultation after you did and before we realized we had alreadly consulted with you." Obviously, specific details would not available because that is exactly why the conflict of interest is being claimed.
