Uh, if the masterpiece painting was sold without the knowledge or permission of the owner, then yes, the buyer would have to return it when that fact was discovered. Duh.
I don't think you're done "recovering" yet.
The woman’s children “DONATED” THE COUCH TO THE SALVATION ARMY.That is like “selling it in a garage sale”. when you donate something you give up rights to it. No doubt when the woman went into the nursing home, they got rid of the mother’s belongings that weren’t given to them or items she wanted to take with her to the nursing home. By your logic anyone who helps their parents move into a nursing home and donates items to a charity or has a garage sale for their parents,must then assume that the value of the item must be reimbursed no matter how many people get it.
that would defeat the purpose of ‘donations”.
