About Property Issue

My great grandfather & grandfather has 15 acres of land. My grandfather had 3 sons. After his demise 3 sons divided the property & took 5 acres each & legally registered on their names. Now my father (2nd son of grandfather) has 2 sons & 1 daughter. All of them are married. Recently I and my brother (both sons) purchased property (Agri land/house) from my father. Dad also agreed for the same and everything happened legally through the sale deed in 2021. Now the question is my sister (daughter of my father) have any right to claim on the property. Because she is saying she will file a case. Please help me on this issue.
