My father (now 80 years old) and his two brothers constructed houses on a plot of land originally inherited from thier father (my grand father) with a mutual understanding. In due course of time they divided legally between them this property with each having his plot defined with the house thereon. My father has willed (registered will) his house equally to me & my brother. Can my two married sisters (married in late seventies) challange the will and claim a share in this house. If he left no will then what would be the status. Thank you.
