Discover how to challenge a will for unfair exclusions in England and Wales. This comprehensive guide explains the Inheritance (Provision for Family and Dependants) Act 1975, your legal rights if left out of a will, who can claim, how the court assesses reasonable financial provision, procedural steps, time limits and practical considerations.

When a person dies and leaves a will, they are generally free to decide how to distribute their estate. However, there are legal avenues for challenging the financial outcome where a will's terms result in someone being unfairly excluded or left without reasonable provision. This article explains your rights and options for challenging a will on the basis of unfair exclusions in England and Wales. It covers the relevant law, who can bring a claim, the steps to take, time limits, possible outcomes, risks and practical considerations.
What Unfair Exclusions from a Will Mean
Under English law, a will is legally valid as long as it meets formal requirements and the testator (the person who made it) had the necessary mental capacity and freedom from undue influence when signing it. Simply being unhappy or surprised by an exclusion does not in itself make a will invalid.
An unfair exclusion typically arises where the will's provisions do not make reasonable financial provision for someone who had a recognised legal relationship with the deceased, or where their financial needs are left unmet despite dependence on the deceased. In these cases, the law provides a statutory route to challenge the financial outcome via the Inheritance (Provision for Family and Dependants) Act 1975 (“the Inheritance Act 1975”).
Legal Framework: The Inheritance (Provision for Family and Dependants) Act 1975
The Inheritance Act 1975 is the principal legal mechanism for addressing situations where someone feels they have been unfairly excluded or inadequately provided for in a will. It enables eligible people to ask the court to make reasonable financial provision from the deceased's estate if the will or intestacy arrangement fails to do so.
Unlike challenging the validity of a will (e.g., on grounds such as lack of testamentary capacity or undue influence), an Inheritance Act claim does not assert that the will is invalid. Instead, it asks the court to adjust outcomes to meet legal standards of provision.
Who Can Make an Inheritance Act Claim
The law limits eligibility to particular categories of people who were close to or dependent on the deceased. These include:
- Spouse or civil partner, including people in long‑term civil partnerships.
- Former spouse or civil partner (provided they have not remarried or re‑partnered).
- Cohabiting partners (people who lived with the deceased as if they were a spouse for at least two years immediately before death).
- Children of the deceased, including biological, adopted and stepchildren.
- Persons treated as a child of the family (for example, stepchildren who were integrated into the family).
- Dependants – individuals who were being financially maintained by the deceased immediately before death.
People in these categories may challenge the outcome of a will even if the will is otherwise valid.
When You Can Challenge a Will for Unfair Exclusion
Claims for Reasonable Financial Provision
If you qualify under the Inheritance Act categories above and you have been left out of a will or left with inadequate provision compared with your financial needs, you can apply to the court for reasonable financial provision.
The court's powers under the Act may include issuing an order that:
- provides a lump sum from the estate,
- allocates periodical payments,
- directs the transfer or sale of assets, or
- imposes a trust to secure ongoing support.
The legal test is whether the will (or intestacy outcome where no valid will exists) fails to make reasonable financial provision for the claimant's maintenance or, in the case of a spouse or civil partner, provision that is reasonable in all the circumstances.
Step‑by‑Step: How to Bring a Challenge
1. Early Assessment and Evidence Gathering
Start by assessing your eligibility and the strength of your claim. Important evidence may include:
- Family and relationship history with the deceased,
- Financial records showing dependency on the deceased,
- Details of the estate assets and how the will provisions apply, and
- Any correspondence or notes that indicate financial dependence.
Documenting your circumstances thoroughly increases the likelihood the court will take your claim seriously.
2. Enter a Caveat (If Probate Not Yet Granted)
If probate has not yet been granted and you need time to prepare your case, you may be able to lodge a caveat with the Probate Registry. A caveat prevents the grant of probate being issued for six months, allowing time to prepare your challenge.
3. Issue a Court Claim
Claims under the Inheritance Act must be formally lodged at court. The claim form should clearly set out:
- Your relationship with the deceased,
- Your financial needs and dependency,
- Why the will fails to provide reasonable financial provision,
- The specific orders you are asking the court to make.
A solicitor experienced in inheritance disputes can help tailor the claim form and supporting evidence.
4. Negotiation and Alternative Dispute Resolution
Many inheritance disputes are resolved before a full court hearing. Early negotiation between the claimant, executors and other beneficiaries - possibly with mediation - can save time and reduce legal costs.
5. Court Hearing
If negotiation does not resolve the dispute, the case proceeds to court. The judge will assess all evidence, consider statutory factors (including your financial needs, the size and nature of the estate, and the deceased's intentions) and make a decision.
Time Limits and Practical Considerations
Time limits are critical in inheritance challenges:
- Inheritance Act claims generally must be brought within six months of the grant of probate (or letters of administration).
- The court can, in rare circumstances, allow a claim outside this period if there is a compelling reason, but this is exceptional.
- If you delay too long, key evidence may be lost, assets may be distributed, and courts may be less sympathetic to a claim.
There is no strictly defined time limit to challenge a will's validity (for example, on grounds of undue influence or lack of capacity), but delays in those types of claims can seriously weaken your position.
Common Questions About Unfair Exclusions
Can I challenge a will just because I feel it's unfair?
If the will is valid but leaves you with nothing or insufficient provision and you meet the eligibility criteria under the Inheritance Act 1975, you can apply to the court for reasonable financial provision. This is not simply about fairness in a moral sense but about whether financial need and legal criteria are satisfied.
Does challenging a will affect its validity?
A claim under the Inheritance Act does not contest the legal validity of the will itself. It seeks to adjust the outcome so that you receive adequate financial provision from the estate.
What orders can the court make?
The court may order financial awards, transfer or sale of assets, or even periodic payments to ensure provision meets legal standards.
What if the estate has already been distributed?
If assets have been distributed, making a claim becomes more complex. Nevertheless, claims can still be pursued, although practical recovery of assets may be more difficult.
Do no‑contest clauses prevent claims?
No‑contest clauses may deter certain challenges, but they do not prevent Inheritance Act claims, because public policy protects access to the court for eligible claimants.
Risks and Challenges
Challenging a will for unfair exclusions is inherently complex and carries risks:
- Legal costs: Litigation can be expensive, and unsuccessful claimants may be ordered to pay some of the other party's costs.
- Evidence hurdles: The claimant must produce credible and relevant evidence to support their claim.
- Emotional stress: Inheritance disputes often arise during periods of grief and can strain family relationships.
Early legal advice can help you assess whether a claim is viable, understand your likely prospects, and manage costs and risks effectively.
Key Takeaways
Challenging a will for unfair exclusions in England and Wales centres on the Inheritance (Provision for Family and Dependants) Act 1975. This statutory route allows eligible people to claim reasonable financial provision from an estate where a will leaves them without adequate support, even if the will is otherwise valid. Key steps include checking eligibility, gathering evidence, lodging a claim within the six‑month period after probate, and, where possible, using negotiation or mediation before court action. The process requires careful preparation, strict adherence to deadlines and, in most cases, specialist legal guidance.
