While English law champions “testamentary freedom”, the right to leave your money to whomever you choose, this right is not absolute. For an estranged adult child, under the Inheritance (Provision for Family and Dependants) Act 1975, adult children who have been disinherited or left an inadequate sum can challenge the Will. Unlike claims by spouses, an adult child’s claim is limited to “maintenance” rather than a general share of the estate. Following the landmark Supreme Court case of Ilott v The Blue Cross [2017], the court balances the child’s financial need against the deceased’s wishes and the needs of other beneficiaries. This article explores the “moral obligation” test, the impact of estrangement, and what constitutes “reasonable financial provision” for an adult.

The Myth of Total Testamentary Freedom
Many parents believe that because they worked for their money, they have an absolute right to “cut out” a child they disagree with. While that is the starting point in the UK, the Inheritance Act 1975 acts as a safety net.
The law allows an adult child (including adopted children) to apply to the court on the basis that the Will, or the Rules of Intestacy—does not make “reasonable financial provision” for them. However, for an adult child, “reasonable” is strictly defined as what is required for their maintenance. This isn’t a “windfall” or a “fair share”; it is about what you need to live.
The “Ilott v Blue Cross” Standard
If you are an adult child considering a claim, you must understand the case of Ilott v The Blue Cross. Heather Ilott was an estranged daughter who was left nothing in her mother’s Will, which instead gave the entire estate to animal charities.
The Supreme Court eventually ruled that while she was entitled to something, the amount was modest. The case established several key principles:
- Estrangement Matters: If you chose to cut ties with your parent, the court may reduce your award.
- Charities Have Rights: The court respects the deceased’s choice to leave money to charity, even if the child is in need.
- Maintenance is King: The award is meant to meet day-to-day living expenses, not necessarily to buy a house or clear all debts.
The Five Factors the Court Considers
When an adult child brings a claim, the Judge will look at the Section 3 Factors:
- Financial Resources and Needs: What do you earn, what do you own, and what are your monthly outgoings? The court will also look at your future needs (e.g., retirement or disability).
- The Size of the Estate: A claim against a £2 million estate is viewed differently than a claim against a £100,000 estate.
- Moral Obligation: Did the parent promise to look after you? Did you work for them for free? Or did you cause them significant distress?
- Disabilities: Any physical or mental impairment significantly strengthens an adult child’s claim for maintenance.
- Conduct: The “why” behind the estrangement is scrutinized. Was it the parent’s fault or the child’s?
Overcoming Estrangement: The Estranged Adult Child
We often see cases where the estrangement was not the child’s choice. Perhaps the parent was difficult, or a new spouse “poisoned the well.” If you can show that you made efforts to reconcile or that the parent’s behavior was the primary cause of the rift, the court is much more likely to look favorably on your claim.
Estrangement is a “factor,” but it is not an automatic bar to success. Your current financial hardship often outweighs the fact that you haven’t spoken in a decade.
What Does “Maintenance” Actually Look Like?
“Maintenance” is a flexible term. It can include:
- A lump sum to pay off a mortgage or provide a deposit for a home.
- Funds to cover retraining for a new career.
- Payments to cover ongoing medical costs.
- An income supplement for someone living on a low pension.
The court’s goal is to provide a “cushion” for the claimant, not to rewrite the Will to make it “equal” among siblings.
The Strict 6-Month Deadline
This is the most critical piece of advice for any disinherited or estranged adult child: You have exactly 6 months from the date the Grant of Probate is issued to file your claim.
If you miss this deadline, your right to claim is almost certainly lost. Because gathering financial evidence and attempting mediation takes time, you must contact a solicitor the moment you realize you have been left out of the Will.

FAQs
1. If I am an estranged adult child who is financially stable and wealthy, can I still claim?
Highly unlikely. Because the standard for adult children is “maintenance,” if you are already comfortable, have a high income, and own your own home, the court will likely rule that the lack of provision in the Will is “reasonable.” These claims are primarily for those in genuine financial need.
2. Can I claim if my parent died without a Will (Intestacy)?
Yes. If the Rules of Intestacy mean you get nothing (for example, if everything goes to a new spouse of your parent), you can still use the Inheritance Act 1975 to claim that the Intestacy Rules have failed to make reasonable provision for you.
3. Will the court look at my spouse’s income during my claim?
es. The court looks at the “financial resources and needs” of the applicant. This includes the household income. If your spouse is very wealthy, it may undermine your claim that you “need” maintenance from the estate.
