Daughter's Rights On Father's Farm Land

FYI, The Hindu Succession Act, 1956, was amended in 2005 to give daughters an equal share in parental property. In case of ancestral property, a daughter now has a share in it by virtue of birth, while self-acquired property is distributed as per the provisions of the will. If the father passes away without a will, she has the same rights as the son in both ancestral and self-acquired property.

what is the date of death of father? what is the basis for the transfer of the property in the name of sons? any WILL? provide complete details for a relevant revert

you have both the options civil as well as criminal file suit for declaration

You have to file suit for partition and cancellation of such names. File a criminal case if they did not disclosed your name at the time of change of katha in their names.
