Legal document needed

I am co-executor of an estate. The other co-executor has restricted my access to all assets by changing the locks to the home where assets are located. I am trying to probate the will myself, pro se, so I need a legal document to send to the other co-executor so I can demand access to the assets for inventory purposes ASAP. However I need the assets relocated to a neutral location where I can have unrestricted access. I am located in Fulton county, Georgia, USA. I’m sure I will need more help after this.
