Simple summary of the case

The core of this legal battle revolves around the last will of Mr. Donald James King. Mr. Rodney James King, the deceased’s son, challenged the validity of the will, which was significantly changed just before his father’s death. The new will largely benefited Ms. Susan May King, who was also named as the executor. Mr. Rodney King argued that his father was pressured and unduly influenced by Ms. King into making these changes. He claimed that his father, who was in poor health and dependent on Ms. King for care, wasn’t of sound mind or acting freely when he signed the revised will. Ms. King, on the other hand, maintained that the changes were made willingly and that she had not coerced her late partner. The court had to carefully examine the evidence to determine if the deceased’s wishes truly reflected his own intentions or if they were the product of manipulation by Ms. King.

Judgement summary

The Supreme Court of New South Wales ultimately found in favour of Ms. Susan May King, upholding the validity of the contested will. The court carefully considered the evidence presented by both parties regarding the deceased’s state of mind and the nature of his relationship with Ms. King. While acknowledging that the deceased was in a vulnerable position due to his ill health and reliance on Ms. King for care, the court found insufficient evidence to prove that Ms. King exerted duress or undue influence. The judge noted that the deceased had made substantial changes to his will on previous occasions and had sought independent legal advice when making the most recent alterations. This independent advice, coupled with the deceased’s clear instructions to his solicitor, indicated that the changes were a result of his own considered decisions rather than external pressure. The court concluded that Mr. Rodney King had not discharged the burden of proving that the will was not the true testamentary intention of the deceased. Therefore, the will was admitted to probate, and Ms. King proceeded with her duties as executor according to its terms.
