Dear Sir,
1) Property inherited by a Hindu male from his father, paternal grandfather, and so on is ancestral property. The children, grandchildren, and great-grandchildren of the person receives their claim to a share in it by birth.
2) Once an ancestral property is partitioned amongst the coparceners it loses the characteristic of ancestral property and becomes self-acquired property.
3) For example if before the birth of A and B children, if both sons had partitioned property then the property would have become self acquired property of both sons, and would have been equally divided between the father and both sons in 1/3. The children would not have had a right in their fathers self acquired property.
3) Since the property was inherited and not partitioned it is ancestral property.
4) If the property gets divided now then then E and F will have right to claim part from theirs fathers A And B 's Share of the ancestral property.
Thank you
