I'm in the same situation. My divorce started in March 2023, and it will DEFINITELY end in September. I filed with a waiver, as if my divorce was completed with an assumed date. I also wrote a personal statement about how my marriage ended. I shared a slip from the family court proving when I filed for divorce. In my personal statement and in my cover letter, explained that in CA summary dissolution takes exactly six months, and that I was going to share the final decree as soon as I get it. I filed in July 2023, my case is actively being reviewed for over a week now.
