My grandfather died intestate,leaving behind a son(my father) and a daughter.My grandmother also died intestate.I am the only daughter of my father.My aunt,i.e,my father's sister,has one son and one daughter.Both my father and my aunt died intestate.Now we have to partition my grandfather's property.
1.Does this mean me and my cousins are part of HUF
You and your cousins are co-parcenars of the property. You can divide the property as your share is 1/2, your cousins share is 1/2. If your cousins may devide into two share @ each 1/2 and 1/2 in division of 1/2. i.e. you will get 1/2 share, one cousin will get 1/4th and the remaining cousin will get 1/4 th share. consult an able local counsel.
For those questions, where answers can be found with details in google search, do not use the forum meant for expert advice.. Just make a google search with key word "Co-parcenar and you can find pages of information.
