Will and Ancestral Right

Dear Client,

Under Hindu Succession Act, 1956, to claim a property as ancestral you do not need a strict four-generation certificate, but you must prove through documents like title deeds, revenue records, and family lineage that the property has descended undivided through generations and was not self-acquired at any point, as any break in inheritance can defeat the claim, while for challenging a Will, a signature mismatch can be a valid ground and a forensic report is admissible under Indian Evidence Act, 1872, but there is no fixed rule like “60% mismatch,” and courts decide based on overall evidence such as attesting witnesses, execution of the Will, and surrounding suspicious circumstances, not just the handwriting difference alone.

Dear client,

Under the Hindu Succession Act, 1956, the concept of ancestral property is well settled:

Ancestral property is property inherited by a Hindu from his father, grandfather, or great-grandfather (i.e., up to four generations of male lineage).
The property must remain undivided; once partitioned, it loses its ancestral character.

if you are claiming a share as ancestral property, you must establish:

The lineage (family tree showing succession up to great-grandfather)
That the property was inherited and not self-acquired
That it remained unpartitioned

Under the Indian Evidence Act, 1872 and Indian Succession Act, 1925:

A Will must be:
Signed by the testator
Attested by at least two witnesses


There is no fixed legal threshold like “60% mismatch” in law.
However, a forensic handwriting expert’s opinion is admissible evidence.

When a Will can be successfully challenged:
Suspicious circumstances (e.g., unnatural disposition, exclusion of legal heirs)
Doubtful signature or forgery
Lack of proper attestation
Testator lacked sound mind

A strong forensic report showing signature mismatch can significantly weaken the Will, especially if combined with other suspicious factors—but alone it may not be sufficient unless it creates serious doubt in the court’s mind
You must prove inheritance through lineage and continuity; documentary evidence is crucial but not rigidly limited to “four documents.”
Signature mismatch is a valid ground, but success depends on overall evidence, not just percentage difference.
