Who should receive the assets left by my father in law according to Quran and Sunnah?

As Salam-O-Alaikum My father in law died, leaving a 10 marla house , a car and defense saving/national saving certificates worth 24200000 Rs. He has only one daughter. He left behind a widow (second wife) with no children (she isn?t pregnant). His only daughter is from first wife, who (the first wife) died in my father in law’s life. He (my father in law) also had five brothers and four sisters of whome a brother and a sister died in his own life.Now remaining are four brothers and three sisters alive, one of the sisters is from step mother of my father in law (But same father). My father in law, in his life, announced (written form) his only daughter as ?NOMINEE? for certificates and house. My father in law’s parents had also died in his life. Kindly provide us a fatwa in accordance with Quran and Sunnah regarding distribution of assets which he (my father in law) left behind.Just for your kind information the deceased and we all belong and follow Hanfi School of thought.
