What documents can I provide as proof for the termination of my previous marriage for my I-485 application?

I was divorced before married to my current partner who filed an I-485 for me. I received a Request for Evidence letter from USCIS asking for documents that can prove that my previous marriage ended legally. I have tried every other way but could not find/obtain my divorce deed. What else can I submit? I have a marriage status certificate stating that I was divorced before marrying to my current partner. Would this work?
