My Uncle had released his 50% property share in favour of his mother "Mrs ABC" in 1986.
This was through a registered release deed.
He made a written undertaking that in future - his children & wife cannot claim on this property of "Mrs ABC".
Can the children & wife claim from court at this stage as legal heirs in the absence of will of "Mrs ABC".
Can they refuse to accept their father's wriiten statement made in 1986.
