Yes Tony,your case was on the shortest will admitted to probate here; it read simply "All to Mother" and it did get to court. The court held that the testator intended his property to pass to his wife because there was clear evidence that he was in the habit of referring to his wife as "mother", she being the mother of his children, and it was manifestly unlikely that he intended to disinherit her, with whom he was happily cohabitng. leaving her with nothing, in favour of his mother.
I think we can take it that wife and mother-in-law were not on the best of terms!
A cautionary tale for all who write wills.
