A judge in Australia ruled this week that Betty Harris's revised will was valid, and she had every right to disinherit her relatives and leave her multi-million-dollar estate to the nice people who live next door.

Prior to her death in 2009, Harris — a childless widow who lived alone in her mansion on Sydney's "millionaire's row" — reportedly became convinced that her "pathetic" nieces and nephews were trying to put her in a nursing home and seize control of her estimated $12.5 million fortune.

"I am determined that my relatives after what they have put me through will not get one cent," Harris said before her will rewritten in 2005 to make next-door neighbors Beatrice and Robert Gray the inheritors of her estate. "The Grays would be surprised, (while) my family are waiting for me to die."
