Will is valid or not

My grandfather died instate leaving behind my grandma my father uncle and aunt in 1969. In 1979 My father uncle and my grandma entered into family partition and got their respective shares. Then My father bought a property in 1986. Now he has two property, 1)his share from partition 2) he bought after partition. My father has a son and two daughters through his first wife and I was born in 1991 to his second wife whom he married after the death of 1st wife.He bequeathed the 2nd property to me in 2001 and in 2004 my father and we entered into family partition were he stated that we are joint hindu family , these are the properties that i got under the partition with my brother and mother and from the income of this property as the karta of the family i got the second one in my name till now we enjoyed in common and we cannot from now so we are dividing. In partition my father takes the property that he bequeathed to me in his name and we all got the rest the property. In partition my father didnt mentioned about the will. My father died in 2006. My question is whether the will is valid to me after my father's death or it becomes joint family property ?
