A person inherited property mutated into their name after their father's death in 1967. Their grandfather had divided the property, and it was registered under the individual's name. Now, the sister is claiming a share, questioning if it's ancestral property. The consensus is that if the property was ancestral and passed down through four generations (self, father, grandfather, great-grandfather), the sister likely has a claim. However, if the grandfather transferred the property directly to the individual during his lifetime, it may not be considered ancestral, and the sister might not have a right to a share.
