My sister living with me who is single passed away. I have one sister and a brother. How will her property be divided and she have also nominated me as her beneficiary 100% in some of her property.

1. If you have parents, they will inherit from your sister's (daughters)
estate. The mother will inherit 1/6 and your father will inherit the
remainder of the estate. The brother and sisters will not inherit. You will
receive only as bequest to the maximum of 1/3 of her estate.
2. If you do not have parents, then your sister's estate will be divided
into 3 equal shares. Two for the brother and one for you.

The above is according to our understanding that the one sister referred to
have passed away.

and Allah Ta'ala Knows Best
