I'm a bit confused as to the facts of the case. However, if I understand them correctly he filed for a change of venue and she filed a response stating her disagreement of such change. She then served the response incorrectly. My answer would be that it is probably still in his best interest to attend the hearing even though she served him incorrectly since it is he who is requesting the change of venue. The hearing would have been scheduled regardless. When he attends the hearing he can let the court know that he was not served properly. The court will then either set another hearing so that she can serve him correctly or will ask if he wishes to waive service and then proceed. Best of luck!
The information you obtain in my answer does not, nor is it intended to, create an attorney-client relationship. You should consult an experience attorney who has knowledge of all the particular facts of your case before making any final decisions.
