Inheritance disputes can be complex, especially when family relationships span multiple generations. One common question we encounter at Blackstone Solicitors is whether grandchildren have the legal right to contest a will. The answer depends on several factors, including the nature of the challenge, the grandchild’s relationship with the deceased, and the contents of the will itself.
This article explores the circumstances under which grandchildren may contest a will in England and Wales, the legal grounds available, and how our expert team can assist in navigating these sensitive matters.

Understanding the Role of Grandchildren in Inheritance
Unlike spouses, children, or civil partners, grandchildren do not have automatic rights to inherit under English and Welsh law. Their entitlement typically arises in one of the following scenarios:
- They are named as beneficiaries in the will
- Their parent (the deceased’s child) has died, and they inherit by substitution
- They are financially dependent on the deceased
- They are entitled under intestacy rules if no valid will exists
If a grandchild is excluded from a will or receives less than expected, they may consider contesting the will. However, their ability to do so depends on the legal basis of the challenge.
Legal Grounds for Contesting a Will
There are two main routes through which a grandchild may contest a will:
- Challenging the validity of the will itself
- Making a claim for financial provision under the Inheritance (Provision for Family and Dependants) Act 1975
Each route has distinct requirements and implications.
- Challenging the Validity of the Will
A grandchild may seek to have the will declared invalid if there are concerns about how it was made. The recognised legal grounds include:
Lack of Testamentary Capacity
If the testator (the person making the will) lacked mental capacity at the time of execution—due to dementia, illness, or cognitive impairment—the will may be invalid. Medical records and witness testimony are often crucial in such cases.
Undue Influence
If someone exerted pressure or manipulated the testator into making or changing the will, it may not reflect their true intentions. Proving undue influence is challenging and requires strong evidence of coercion or exploitation.
Lack of Knowledge and Approval
A will may be invalid if the testator did not fully understand or approve its contents. This may arise if the will was drafted by someone else or signed under suspicious circumstances.
Improper Execution
Under the Wills Act 1837, a valid will must be:
- In writing
- Signed by the testator
- Witnessed by two individuals present at the same time
Failure to meet these formalities can render the will invalid.
Fraud or Forgery
If the will was forged or the testator was misled into signing it, the document may be challenged. These are serious allegations and require substantial proof.
If a grandchild successfully challenges the validity of the will, the estate may be distributed under a previous valid will or according to intestacy rules.
- Claiming Financial Provision Under the Inheritance Act
Even if the will is valid, a grandchild may be able to claim financial provision under the Inheritance (Provision for Family and Dependants) Act 1975. This legislation allows certain individuals to apply for reasonable provision from the estate if the will (or intestacy) fails to provide adequately.
Eligibility of Grandchildren
Grandchildren are not automatically entitled to claim under the Act. However, they may qualify if:
- They were financially dependent on the deceased
- They were treated as a child of the family
- They lived with the deceased and received regular support
Examples of dependency include:
- Living with grandparents and receiving financial support
- Being paid school fees, rent, or living expenses
- Receiving regular gifts or allowances
The court will consider the nature, extent, and duration of the dependency when assessing eligibility.
Types of Provision
The court may award:
- Lump sums
- Periodic payments
- Transfer of property
- Variation of the will’s terms
The aim is to ensure the claimant receives reasonable provision for their maintenance, not necessarily an equal share of the estate.
Factors the Court Will Consider
When assessing a claim under the Inheritance Act, the court will examine:
- The financial needs and resources of the claimant
- The size and nature of the estate
- The relationship between the claimant and the deceased
- Any obligations or responsibilities the deceased had towards the claimant
- The needs of other beneficiaries
- Any physical or mental disabilities
- Any other relevant circumstances
Each case is judged on its own merits. A grandchild’s claim may succeed even if they are not named in the will, provided they can demonstrate genuine need and dependency.
Time Limits for Contesting a Will
Time limits vary depending on the nature of the claim:
- Inheritance Act claims must be made within six months of the grant of probate
- Validity challenges should be brought as soon as possible
- Fraud or forgery claims may not have a strict time limit, but delay can weaken the case
Prompt legal advice is essential to preserve rights and gather evidence.
What Happens If a Grandchild’s Claim Succeeds?
If a grandchild successfully contests a will:
- The will may be declared invalid, and the estate redistributed
- The court may order financial provision from the estate
- Other beneficiaries may receive reduced shares
- Executors may be required to revise the estate administration
In some cases, disputes can be resolved through negotiation or mediation, avoiding the need for court proceedings.
