Mil Passed And Sil Is Trying To Sue Us For Abandoned Items

Located in Wisconsin. My MIL passed away suddenly. She did not have a will. She has 4 adult children. 1, the youngest, was living with her at time of passing. My husband is oldest so he was elected executor. My MIL had a home and we were forced to sell it. SIL was forced to move and left a bunch of items in the house. She lived in the house for over a month after MIL passed and trashed the place. We had to clean it and moved everything out into the enclosed garage. We told her she needed to get her items. After another 3 months we Had our lawyer email her to remove her items because we had a buyer for the house. She told the lawyer she would get them the following weekend. She came and collected some of the items but left a bunch of stuff. We closed on the house and she never came back so we threw everything away in a dumpster.

In all she had over 4 months to get anything she wanted from the house. We considered it abandoned at that point and trash. Plus with the sale it needed to be removed.

It’s been 9 months. House is sold. She is now saying she will sue us for the items she left. We have photos and emails to show dates and time stamps of all things.

Can she sue us and win? We gave her plenty of time and access. She had the code to unlock the doors at anytime she wanted. She had a working vehicle and transportation and a place she lived to store it.

Any advice would be appreciated. We are just trying to be prepared.
