If he's not a witness in the case, then he can go to the courthouse, the courtroom and assist you.

It depends on what type of help he will provide. He can be in the courtroom (as long as he is not a witness), and the judge may let him sit at counsel table to assist you, particularly if you are disabled. However, he will not be allowed to speak to the court or do anything to help you that would be seen as practicing law. Either way, if you have a case important enough to be in court (other than small claims), you should really get a lawyer to make sure it is done right.
The term, "trial consultant," suggests a professional engaged in the business of trial tactics and strategy, which is an occupation a lawyers is engaged in, not a layperson. If what you want is for your husband to sit at your table with you and assist you in organizing your trial exhibits and to provide occasional off the record advice to you during trial, then that should be allowed. He cannot, however, make statements to the court, ask questions of witnesses, answer questions the judge directs to you, make arguments, etc. only a licensed lawyer may do that for a party in a case. You, as the named party, are allowed to act as your own lawyer. If you anticipate the possibility of your husband testifying in the case, then it would not be a good idea to have him assist you at the trial table. Either party may request a "Rule on Witnesses" which means the judge will order all persons other than the named litigants in the case who may be called to testify to leave the courtroom and not discuss the case. The purpose is to prevent witnesses from hearing other testimony and changing their testimony to conform to or respond to what others have said. Even if no one asks for a rule on witnesses, a judge may give less credence to a witness who has sat in the courtroom and heard everything that's been said.
