Grand daughter rights on grand mother property

Hi Sir,

My grandmother holds a property , which was given to her by slum board corporation from world bank fund.

do i have rights on the property. My grandmother denies to give my mother's share on this property.

can any give me a suggestion. 

The property held by your grand mother is her absolute property. Your mother can get a share in your grandmother property only when your grandmother died intestate(died without writing a WILL). Otherwise,  can't get the share (i.e., if she executes a WILL , in that WILL she must mention the beneficiary of the property. The beneficiary shall get the property.)
