Can woman claim share in grandfather’s property through court?

My grandfather had self-acquired property (a shop and a house). After his death, my grandmother made a will in favor of their three sons: Roshan, Sahil, and Raj. Roshan has two sons and one married daughter named Priya. After her marriage, Priya didn’t know how the property was divided. In the Jamabandi, her name is missing, while Roshan, Sahil, Raj, and their wives are listed. Both of Roshan’s sons got a share, but Priya did not. One of Roshan’s sons, Ajay, has filed a partition suit against his uncles Sahil and Raj. Questions: • Can Priya file a partition suit against her brother Ajay? • Is a coparcenary created in this case? • Can the grandmother legally make a will? • Can Priya still claim a share in the property?
