ANSWER:

Her share ends as soon as she dies before her parents and you cannot inherit her share from your grandparents inheritance. 

I am a 36 year old woman, my mother passed away when I was 18. She died before her parents. I wanted to know if her share in her father’s property remains or it ends as soon as her life ends even before the death of her parents. If it still remains, can her children (me and my brother) inherit my mother’s share from her father’s property?
