Daughter died before mother -muslim law

Hey I'm Joe, I would like to ask a question.My family is a Muslim family. My mom died before my grandmother. After 14 years my grandmother transferred a farm property to my name as soon as I reached 18.When I turned 18(while she(grandmother)was alive, it came to my name. After my grandmother died 4 years ago. The elder son and younger son denied to give me any part in other property will be listed below since my mom died before my grandmother.Then both of them agreed to share the property Among themselves. Is this true? The properties will be 1)house property where a three storey building constructed when my grandmother is alive by her. 2)Farm lands which they got to know that one of it was given to me. They choose to take the remaining after my grandmother died . 3)Some 90 cent house property.40 was written and given to the elder son when my grandmother was alive.the remaining 50 was given to younger son by agreement between both after grandmother death since the elder one the first 3 storey house land. Do I share any property as a heir to my mom? If I do what is the law code that states such? Because the lawyer I went and see in ramnathapuram said I don't have any right. I hope you all can help me.. Thank you so much.
