my husband and i cld not agree on the terms of our divorce decree so he requested a trial and it was scheduled. since then we have agreed

but we have not signed the decree but we do not want to go to trial. my husband is stating that his attorney is saying my husband can not request to cancel the trial date because we have agreed until we sign the papers. is this true? he is insisting that if we do not sign the final decree papers before the trial date we have to go through with the trial which we do not want to do. does my husband not have the right to request to cancel the trial since he was the one who requested it in the first place and no longer wants it?
