Zakah on lost person's money

A: If the reality is as you mentioned, the case of this person should be referred to the Shar`y Court to apply the procedures of a missing person. As for the money allocated to him from the estate of his father, there is no Zakah due on it until its owner knows about it. To put it in plain words, a Hawl (one lunar year calculated from the time a property reaches the minimum amount upon which Zakah is due) of Zakah due on it begins when its owner both knows about it and has the ability to possess it.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
