He needs to call the Domestic Relations Office in the county where the warrant was issued immediately to inform them that he did not receive any notice of the support proceedings in that county until he looked on-line. He should also tell them that he has a conference today and that he will straighten it out with the conference officer. If he has an attorney, he/she can make that call for him.
My response is based solely on the limited information contained in the question. It is not meant to substitute your attorney's advice.
I agree with attorney Silverman. I would add that he should not skip this present hearing or another warrant could issue. The first one might be remedied with a lack of notice defense, skipping another one will only frustrate his efforts to clear the first one. If the outstanding warrant becomes an issue in this hearing, address it with this judge
