Can daughters claim share in dead father's (1997) property if father wrote will of last property in his son's name but died intestate for second property ?

Father wrote will of one property dividing in 2 half among two of his sons and clearly mentioning that my daughter's are married now and have no claim in property. That property due to some reasons was sold by consent of two willed sons of his and bought new registered by father in his own name. Father died in 1997 , leaving no will as such for the new property. Now,
1) Can the daughters claim share in this property after 21 years ?
2) Would the last will intention clearly mentioning my daughters cannot claim anything in property a valid intention?
3) Do the daughters need to be informed in this case to get their sign done for formalities to change the registry in the two son's name , or can the son's directly approach registry's office ?
