I have a situation where my father has died leaving his wife and 3 sons. We have a flat which is in my fathers name. There is no will and we brothers are ok with transfering the flat to our mother. The society is asking for long procedure to get a heir certificate. Some of my friends have had the same situation and have go the flat transfered to their mother just with affidavits and indeminity bond. Why is the society asking for heir/succession certificate?
