Contesting the validity of a will


If the validity of a will is being challenged, we understand that this can be a confusing and upsetting process. Our experienced lawyers are here to guide you through potential routes of challenge and help secure a fair outcome. We’ll provide you a clear explanation of our costs and the work that we can do for you. 

If you’re considering how to contest a will, these are the main grounds for disputing its validity:

Lack of testamentary capacity 

Testamentary capacity essentially means that the testator was able to understand what they were doing when they prepared and executed their will.  

For a testator to have testamentary capacity, they must have:

  • Understood the nature of making a will
  • Understood the extent of their property
  • Appreciated who they might include as a beneficiary of their estate
  • Not been suffering from any illness or delusions which affected their mental state

If a testator did not have the necessary mental capacity when their will was executed, it will be invalid and any previous valid will or the intestacy rules will govern the distribution of their estate.

Want of knowledge and approval

For a will to be valid, the deceased must have known the contents of the will, either by reading it of having it read to them and approved those contents.

Where it becomes apparent that the contents of the will are not as the testator wanted or expected, the validity of the will can be contested on the basis of ‘want of knowledge and approval’. This may arise when someone has taken advantage of the deceased, or where the deceased was too ill to understand the will, or to read, or have it read to them.

Where a will is found to be invalid, a previous will may take effect, or the intestacy rules may apply. 

Undue influence

Undue influence occurs when an individual uses their power or authority to influence another into preparing a will which doesn’t represent their true wishes. The influence goes beyond persuasion and amounts to coercion. 

This influence and coercion can be by:

  • A family member such as a niece or nephew, child or a partner
  • Can also be by friends, carers or neighbours

Suspicions are often raised when a new will is produced which substantially deviates from previous wills, perhaps benefitting someone who was not previously included in the will, when the testator was elderly or frail, or dependant on that person for care or financial assistance.

Other means to challenge a will include:

  • The will was forged and/or created through fraud
  • The will wasn’t properly executed in accordance with the Wills Act 1937
  • The will didn't reflect the wishes of the deceased due to a clerical error or the will drafter’s failure to understand the deceased’s wishes
  • Alternatively, you may claim under the Inheritance (Provision for Family and Dependants) Act 1975 if you were inadequately provided for in the will and you were married to, a child of, living with, or financially dependent on the deceased.
