A woman who contested her parents' will after they left their £2 million estate to the RSPCA won her legal challenge on Friday.
Christine Gill (58), from Northallerton, North Yorkshire, launched her legal battle in July last year to challenge the will, which she claimed her father coerced her mother into making.
After her mother's death in 2006, Gill discovered her parents, John and Joyce Gill, had made wills leaving their 287-acre farm to each other and then to the animal charity when both died.
During previous High Court hearings in Leeds, Judge James Allen had heard how the daughter - an only child - was given repeated assurances that she would inherit Potto Carr Farm, in North Yorkshire, when her parents died.
The university lecturer told the court she had devoted most of her spare time over a period of more than 30 years to voluntarily helping out at the farm.
When her father died in 1999, aged 82, Ms Gill was left to look after her mother and run the farm, the court heard.
It was only when her mother died in 2006, also aged 82, that she saw the will, which left everything to the RSPCA.
The court heard the mother, who suffered from agoraphobia with panic disorder, went everywhere with her husband, who was said to be stubborn and domineering, and was dependent on him to make decisions for her.
Psychiatrists said it was likely she would have conformed with the wishes of her husband when they made their wills in 1993 but her anxiety and her dependence on him would have made it very difficult for her to understand the proceedings or disagree with what he wanted to do.
But experts disagreed about her mental state, with one telling the court she was an eccentric woman but did not have a formal psychiatric disorder.
The judgment in favour of Christine Gill was handed down in Leeds this morning.
