These are all good questions you should put to your lawyer. No one here online can provide near as good an answer as your own lawyer can. He or she has all the details. It is not a good use of this forum to second guess the advice you get from your lawyer.
Good luck and God bless you.
It may be possible to simply pay the filing fee and file your Answer and Counter Petition with the court to have the case proceed. Unless the district court administrator has an objection to accepting the filing, this may be sufficient to get your case started.
Alternatively, you could serve him with the Summons and Petition for your own case and reference the fact that he initiated but abandoned the previous Petition for Dissolution. Good luck.
