Assuming there was testamentary capacity at the time the Will was made, there is no issue of undue influence and the Will is drafted clearly then the substance of the Will can be contested. This is achieved pursuant to the Inheritance (Family Provision) Act.

This Act states that a person is entitled to claim the benefit of the Inheritance (Family Provision) Act if they have been left without adequate provision for their proper maintenance, education or advancement in life. The Supreme Court may order such provision as it thinks fit out of the assets of the estate of the deceased.
