You can INVENTORY the property she left behind , using video camera and long hand notes , 6 plates lg, 6 plates sm, 8 coffee cup 12 ******i glass , 12 wine goblet, 12 double shot glass, 6 half gallon beer mugs , etc with the video and then ask your atty how many days you should give to her in a letter that tells her if she doesnt come to get the things then they will be disposed of, Send it via certified mail , if she didnt put in a forwarding address too bad it will come back to you DO not open it , if she sues you let her explain to a judge why she didnt change her address or pick up the mail. Inventory records would show the court what she left behind and what shape it was in so when she claims you threw out grannys antique six drawer dresser you can show the court the pics of the rooms before you moved out any thing and let the court see her cardboard faux wood laminate six drawer dresser was there with all her crap in the drawers that were sticking out. (got the idea LOL ) document it all , because it would show that you did take reasonable care to pack up and know what you were packing up before storing it in the garage or a shed or somewhere while waiting for her to respond to your demand to come and get it all.
