Question: How a trustee must keep the property if the owner lost it?
If the owner of the property was lost and no one knows whether he is alive, the trustee must keep the property as long as it will not be aware of the owner's death. In case when there is a risk that the property will deteriorate, the trustee sells the property with the consent of the competent authorities and keep the proceeds. But if a man does not sell a property entrusted to him and the thing is lost, he is not obliged to compensate for the loss (Ibn Abidinzade, Tekmilyu Raddil-Mukhtar, II, 510). When is known for sure about the death of the owner, trustee returns the property to his heirs.
