He can bring up whatever he wnts in mediation. It is not a formal court hearing or trial. He can not use hearsay in court.
IF YOU FOUND THIS ANSWER "Helpful" or " The Best Answer" YOU CAN THANK ATTORNEY RADDATZ BY MARKING IT SO because Avvo awards the attorney points. MS. RADDATZ is donating her time and talent by answering questions to help those in need of legal information. This is NOT a consultation and in no way creates an attorney-client relationship. YOU SHOULD ALWAYS PERSONALLY CONSULT WITH AN ATTORNEY IN YOUR LOCAL AREA who has specific expertise in the area of law you are asking about.
Of course, I am not in Nebraska; so consider that. Your question involves apples and oranges. In Mediation, the floor is basically open; however, in general, if mediation failes; it is considered part of negotiations and cannot be discussed at court. As far as Court, there are simply too many variables for any attorney to answer here on AVVO with the limited information you have provided. Depending on the allegation, if it involves abuse; most states have laws that require a person with knowledge of abuse to report it to the Dept of Children Services (or your states version) and could be in violation of criminal law if they do not. Obviously, your post does not communicate what the allegation is. You bring up hearsay, but do be aware that there are exceptions to hearsay, so there is not a blanket "no" on all hearsay. You would be wise to consult an attorney in your area before attending mediation or court. The results of either can have lasting implications without solid legal counsel. Good luck.
The preceeding is for educational purposes only and an attorney/client relationship is not established. Laws in all states may vary.
He would not be able to bring it up in Court, as there the hearsay rules apply. However, in mediation there is no hearsay ruling. You can certainly mention that there is no evidence of these things, and that you want to stick to the facts during mediation, but there is no law preventing him from bringing it up in mediation. Although, such things should not be mentioned in any mediated plan between the two of you that might be presented to the court.
I am a licensed attorney in the state of Nebraska. However, the advice I give here is not to be taken as legal advice. It is merely my opinion based on the limited information given. In order to assure that your legal rights are being properly represented I would always recommend going in for a consultation with an attorney to explain your case in detail and answer any questions the attorney might have.
