I'm so sorry you are dealing with this. My divorce is in Hinds County as well. My 60 days were up on November 9th and Judge William Singletary signed the papers on November 20th finalizing the no fault divorce. Once my 60 days were up, my attorney called the chancery court and set up a court date. From what my attorney told me, each judge has 1 day a week for Ex Parte (where your attorney takes your papers to the judge on your behalf instead of the husband and wife having to go to court). It sounds to me like your attorney (or the assistant) isn't very experienced...they just need to call the chancery court and make an appointment!
Good luck! I hope that you can get this finalized soon!
