A will should offer certainty, clarity and peace of mind. Yet, for many families, it becomes a source of dispute, confusion or distress particularly when the contents of the will seem unexpected or unfair. In some cases, concerns arise about how the will was prepared, whether it reflects the true wishes of the deceased, or whether certain people have been wrongly excluded.
At David J Forster & Co Solicitors Group, we advise clients throughout England and Wales on all aspects of will disputes and inheritance claims. If you are concerned about a will, or believe you may have grounds to challenge one, our team of specialist contentious probate solicitors can help you assess your position with clarity, discretion and compassion.
When Can a Will Be Challenged?
Wills can be contested in two principal ways:
- By disputing the validity of the will itself, or
- By making a claim for reasonable financial provision under the Inheritance (Provision for Family and Dependants) Act 1975, even where the will is otherwise valid.
Both routes are legally complex and time-sensitive. Understanding your legal position early and taking the right first steps can significantly improve the outcome.
Grounds for Contesting the Validity of a Will
The law sets out specific grounds on which a will can be declared invalid. These include:
1. Lack of Testamentary Capacity
The person making the will must have understood what they were doing, what their estate comprised, and who they owed moral or legal obligations to. If a will was signed at a time when the person lacked capacity, perhaps due to illness, cognitive impairment or undue medication, it may not be legally binding.
2. Undue Influence
A will can be set aside if it was made under pressure, manipulation or coercion. This may involve someone taking control of the testator’s affairs, isolating them from family, or persuading them to make significant changes that benefit one individual to the detriment of others.
3. Improper Execution
A valid will must meet the formal requirements of the Wills Act 1837. If, for example, it was not signed in the presence of two independent witnesses, or if one of the witnesses was also a beneficiary, it may be invalid.
4. Fraud or Forgery
In rare cases, a will may be forged, tampered with or executed on the basis of deceit. Such allegations require immediate legal advice and may involve specialist evidence.
5. Lack of Knowledge and Approval
Even where a will has been properly signed and witnessed, it may still be challenged if the person signing it did not truly understand or approve of its contents, for example, where someone else prepared the document or where its terms were concealed.
What If You Were Left Out or Not Properly Provided For?
Even if a will is valid, the law provides protection for certain people who have not been adequately provided for. Under the Inheritance (Provision for Family and Dependants) Act 1975, you may be entitled to claim financial provision if you were:
- A spouse or civil partner of the deceased;
- A cohabiting partner (living with the deceased for at least two years before death);
- A child or adult child, including those treated as children;
- A person financially dependent on the deceased at the time of death.
These claims are not about rewriting the will but about ensuring fairness where the deceased had a duty to support you. It’s important to note that these claims are usually subject to a six-month time limit from the date of the grant of probate.
Who Can Bring a Will Dispute?
We advise clients who are:
- Named or former beneficiaries;
- Excluded spouses, partners or children;
- Family members concerned about late-stage will changes;
- Executors or trustees concerned about validity or the risk of claims;
- Individuals financially dependent on the deceased who were not included.
If you are uncertain about whether you have a claim, an initial conversation with a solicitor can provide essential clarity.
