The short answer is tenants have a pile of rights..and younare not docuemented well at all.

You might be smarter to arrange a mutual workable pick up date and have her pick up her stuff from the front doorway..do not let her back inside ...get written surrender and return of keys..

A mess is not a likely winnable point as to damages.
