One of my friends father has died. He has made a WILL directing to sell his residential property( which is vacant) and distribute the proceeds in certain manners among sons and daughters. He has made a separate provision for his wife. The property is in joint name with his wife. My friend’s mother is willing to honour the will. Now how to implement the will? Should they apply for a probate or succession certificate? If a person has made a will is it compulsory to produce it in a court?
