property transfer under rule-1 of Hindu Succession Act

Widow being the class 1 heir of X who died intestate, the property of X shall devolve and to the exclusion of all other heirs, those in class 1(son,daughter,widow,mother,etc) shall take simultaneously.If the deceased X has left behind him his widowed wife only as sole legal heir,she can approach concerned revenue authority to mutate the property in to her name on the basis of death certificate of X, heir certificate, etc.

Thanking you,
