He said that it is notable that none of the daughters has made a claim under Section 117 of the Succession Act and “furthermore, neither of the daughters who gave evidence before me suggested that they were living in straitened circumstances".
They rarely are, so there is every point in making a will. And wills are over turned when there is a good reason to, like here. This man worked on the family farm for decades without proper pay on the promise of inheritance, which was then denied to him. I can't see any argument here that the court was wrong to make amends to him.
