In every age and every society, a new situation is created based on which the jurisprudential ruling of a jurisprudential matter should be studied. This paper examines the jurisprudential ruling of the property of unknown ownership considering the situations at the present time and reaches the following conclusions: A) Based on the ruling of those who consider the property held by state banks as the property of unknown ownership, the people, when interacting with these institutions that naturally despair of finding the owner, must take permission of the religious ruler and have the right to seize the amount that the ruler permits. B) Delivering a property of unknown ownership to the institutions established for the management of such properties, like the lost property section at the holy shrines, is allowed if the person designates that institution as his proxy to announce it or to deliver that property to the institution as an instance of announcement. C) If a person makes an announcement on mass media in a way that is regarded sufficient by the wise it is allowed.
