Property sharing

Yes if Hindu look in Hindu Succession (Amended)Act,2005

Hello My Grandfather and Grandmother died without writing any will for their kids. They had three sons two daughters.My dad and older uncle moved to UK and helped out to construct all the property on that land and both died recently 2 years ago . My uncle living on that property is not willing to give any shares of land or const to both the widower (my mom and aunt)  or any share of total earnings coming from rent. My alive uncle living on that property keep on constructing big apartmentS without taking any permissions from my mom and my older aunt. Both my mom and aunt has UK citizenship but no earning since they were housewives.

Can they claim their husband rights on the ancestral property in India?

If yes what is best way to proceed and stop the illegal constructions done with out their permission.

Do they have to take dual citizenship of India, in order to claim the property OR file any petition to stop any construction with out their permissions?

 Please guide and help on proper court proceedings over the rights.

 Thanks!

they have right.they can stop the construction.
