Your Simple Guide to a Contentious Probate Claim
If you’re a stepchild or a parent of a stepchild, here’s a simple guide on how stepchildren can claim if left out of a will. When a loved one dies, it is an emotional time for families and sometimes the contents of a will can come as a shock. So, if a stepchild expected an inheritance but received nothing – or far less than is needed – you may be able to bring a claim for reasonable financial provision.
Such a claim would fall under contentious probate law under the Inheritance (Provision for Family and Dependants) Act 1975 and understanding what to do next can make a significance difference.
We partner with specialist contentious probate solicitors who offer a range of fee structures, including ‘No Win, No Fee’ agreements along with other flexible funding – as well a an initial, no-obligation consultation.

What Is Contentious Probate?
Contentious probate refers to any legal dispute related to the administration of a deceased person’s estate. This may include disagreements about:
The validity of the Will
How an executor is handling the estate
The distribution of assets
Claims for reasonable financial provision under the Inheritance Act
When a stepchild is excluded from a will or receives an inadequate inheritance, challenging the estate is not about simply contesting the deceased’s wishes. It is about ensuring the law provides fair financial support where a genuine dependency existed.
Do Stepchildren Have Rights Under the Inheritance Act?
Yes. Stepchildren can make a claim under the Inheritance (Provision for Family and Dependants) Act 1975. Essentially, a stepchild can claim if they were:
Treated as a “child of the family”
This is the most common route. If the deceased acted in a parental capacity, such as providing financial support, guidance, education, or day-to-day care – the law may view the stepchild as a “child of the family.”
Evidence may include:
Living in the same household
How you were financially supported
Proof that you were included in family decisions
Being raised as the deceased’s own child
You do not need to have been adopted to qualify.
Financially maintained by the deceased
If the stepchild was financially dependent on the deceased, even in part, they may qualify as a “dependant.” Dependency may involve:
Regular payments
Help with bills, rent, or school fees
Gifts forming part of ongoing support
Even infrequent but vital financial help can count.
Why Are Stepchildren Left Out of Wills?
Unfortunately, many stepchildren find themselves left out of a will for reasons that have nothing to do with their relationship with the deceased. Typical reasons may include:
The will is old and predates the blended family
The deceased assumed their spouse would provide for the stepchildren instead
Misunderstandings about how stepchildren are treated legally
Family conflict, disagreements or breakdown
Poor drafting or lack of professional advice
However, the Inheritance Act exists specifically to deal with situations where a person’s will fails to make adequate financial provision for those who depended on them.
What Stepchildren Need to Prove to Bring a Claim
To bring a successful Inheritance Act claim, a stepchild should be able to show that:
They were financially dependent on the deceased OR treated as a child of the family.
The will (or intestacy rules, if no Will exists) fails to make reasonable financial provision.
They have a genuine financial need for maintenance or support.
It is important to understand that reasonable financial provision means the court evaluates what support is appropriate based on the claimant’s circumstances.
What the Court Considers in a Stepchild’s Claim
The court’s considerations typically include:
- The nature and length of the relationship with the deceased
- The level of financial dependency, if any
- The claimant’s current and future financial needs
- The resources and needs of other beneficiaries
- Any obligations the deceased had towards the stepchild
- The size and nature of the estate
- Any physical or mental health issues the claimant faces
The goal is not to make sure that someone who relied on the deceased is not unfairly left without support.
Time Limits for Stepchildren Bringing a Claim
You must act quickly. A stepchild has six months from the date the Grant of Probate is issued to bring a claim.
Missing this deadline can make your claim far more difficult. Courts may grant extensions in exceptional circumstances. But, it’s far safer to obtain legal advice as early as possible.
Evidence That Strengthens a Stepchild’s Claim
Because stepchildren do not automatically qualify as beneficiaries, strong evidence is crucial. Useful documents include:
Bank statements showing financial support
Messages or letters showing a parental relationship
School or medical records listing the deceased as a parent
Family photos and joint activities
Witness statements from family, friends, or neighbours
Receipts or records of shared expenses
The more clearly you can demonstrate your relationship with the deceased, the stronger your claim and chances of success.
Can Stepchildren Contest the Validity of a Will?
Yes, a stepchild may also challenge the will’s validity if there is evidence of:
Why Specialist Contentious Probate Advice Matters
Contentious probate is a highly technical area of law. Claims involving stepchildren are especially complex because the relationship must be demonstrated, and inheritance expectations may be disputed by other beneficiaries.

A specialist probate lawyer can:
- Assess whether you qualify under the Act
- Calculate the strength of your claim
- Gather evidence
- Negotiate with executors and beneficiaries
- Represent you in court if needed
