Returning a stolen object inherited from his parents:
A child is obligated to return to its rightful owner an item that was stolen by his father or mother which he inherited from them after they passed away. This applies even if the item is considered to be legally owned by the child due to Yirush and Shinuiy Reshus. This, however, only applies if the item is potentially recognizable to others that it belonged to someone else and was stolen by his parent, such as a piece of furniture, blue, or clothing. However, money, as well as other items which are not recognizable as having belonged to someone else, do not have to be returned. Likewise, the above obligation only applies if the parent has repented his act of stealing and simply did not get a chance to return the stolen item.
