Estranged Child Inheritance UK (2026): Can You Disinherit an Estranged Son or Daughter?
Ilott v Mitson [2017] UKSC 17 — the leading case on disinheriting adult children
A mother disinherited her estranged daughter and left everything to animal charities. The Supreme Court awarded the daughter £50,000 (from ~£486,000) — affirming that testamentary freedom carries real weight and that the maintenance standard for adult children is deliberately narrow. A detailed letter of wishes was central to the outcome.
Frequently asked questions
Can you legally disinherit an estranged son or daughter in England and Wales?▼
Yes — English law gives testators broad testamentary freedom under the Wills Act 1837. There is no legal obligation to leave anything to an adult child, estranged or otherwise. A parent can leave their entire estate to charity, to a friend, to one child but not another, or to anyone they choose. This distinguishes England and Wales from many civil law jurisdictions (France, Germany, Spain, Scotland) where forced heirship rules give children a minimum share. However, testamentary freedom in England is not absolute — it is qualified by the Inheritance (Provision for Family and Dependants) Act 1975. Under the 1975 Act, a child of the deceased (regardless of age) can apply to the court for 'reasonable financial provision' from the estate if the will (or intestacy) fails to make such provision. For adult children (as opposed to spouses), reasonable financial provision is limited to what is needed for their maintenance — not what they expected to inherit, not a 'fair share', and not compensation for the parent-child relationship. The court has wide discretion and explicitly considers the reasons for estrangement.
Can an estranged adult child make an Inheritance Act 1975 claim?▼
An estranged adult child can bring an Inheritance Act 1975 claim, but the estrangement significantly affects the court's assessment: (1) Who can claim: any child of the deceased — including adult children, regardless of age, regardless of whether they are financially independent, and regardless of how long the estrangement has lasted. Step-children and adopted children may also qualify under s.1(1)(d) (person treated as a child of the family); (2) The standard for adult children: s.1(2)(b) — 'such financial provision as it would be reasonable in all the circumstances of the case for the applicant to receive for his maintenance'. This is deliberately narrow: maintenance means basic needs, not an equal share or even a share proportionate to the estate; (3) The leading case — Ilott v Mitson [2017] UKSC 17: Mrs Ilott was estranged from her mother for 26 years before the mother's death. The mother left her entire estate to animal charities and explicitly explained in a letter that she wanted to exclude her daughter. The Supreme Court awarded Mrs Ilott £50,000 (from an estate of about £486,000), overturning a higher Court of Appeal award of £143,000. The Supreme Court emphasised: (a) testamentary freedom carries real weight; (b) the maintenance standard does not entitle an adult child to a share of the estate; (c) Mrs Ilott had not contributed to the estrangement; (4) The estrangement factor: where the estrangement was caused or substantially contributed to by the child's own conduct (abandoning the parent, criminal behaviour, verbal abuse), the court is far less sympathetic. Where the estrangement was caused by the parent (domestic abuse, abandonment), courts are more willing to make an award; (5) Financial need and circumstances: the court weighs the claimant's own financial resources, earning capacity, disability, and obligations. A financially independent, working adult child with no disabilities will struggle to show a maintenance need.
What is the best way to protect a disinheritance from an Inheritance Act claim?▼
No preparation can eliminate the risk of an Inheritance Act claim being brought, but several practical steps significantly reduce the risk of a successful claim: (1) Write a detailed letter of wishes: this is the single most important protective step. The letter of wishes is a private document that accompanies the will — it is not public and does not need to be disclosed in probate. Write it in your own words, explain: (a) the history of the estrangement — specific incidents, the reasons the relationship broke down, attempts at reconciliation that were rejected; (b) why you do not consider the excluded child to have a financial need that the estate should meet; (c) the positive reasons you are benefiting the beneficiaries you have chosen. The letter of wishes is not binding on the court, but it is highly persuasive evidence of your intention and state of mind. Ilott v Mitson itself turned partly on the mother's letter of wishes; (2) Make the will when you have good capacity: a will that is clearly made with full testamentary capacity and without undue influence is much harder to challenge. If your health is deteriorating, consider a specialist solicitor's will with a detailed capacity assessment. Keep a copy of any clinical records around the time of the will that confirm capacity; (3) Keep records of the estrangement: texts, letters, emails, diary entries, social worker notes — anything that demonstrates the history of the relationship (or non-relationship). Your executor may need this evidence if a claim is made; (4) Consider a trust structure: a discretionary trust (rather than absolute gifts) gives the trustees flexibility to respond to an IA 1975 claim without the estate's intended beneficiaries necessarily suffering the full loss. The trustees can oppose the claim or negotiate a settlement using discretionary powers; (5) Do not disinherit and then maintain financially: if you continue to financially support the estranged child in the years before death (regular payments, accommodation), you are building the very 'maintenance' case that the 1975 Act is designed to protect. If the estrangement is genuine, make sure your financial behaviour reflects it.
Does it matter whether the estranged child caused the breakdown of the relationship?▼
Yes — this is one of the key factors under Inheritance Act 1975 s.3(1)(g), which requires the court to consider 'any other matter, including the conduct of the applicant or any other person, which in the circumstances of the case the court may consider relevant'. In practice, the courts have consistently treated the cause of estrangement as a significant (though not decisive) factor: (1) Estrangement caused by the child's conduct: courts take testamentary freedom most seriously when the child's own behaviour caused the estrangement. If the adult child committed a serious crime, was abusive to the parent or other family members, abandoned the parent in old age, or repeatedly rejected attempts at reconciliation, the court weighs these heavily against making a significant award. The parent's reasons for the exclusion are then consistent with the conduct; (2) Estrangement caused by the parent's conduct: where the estrangement was caused by the deceased parent (abuse, abandonment in childhood, failure to acknowledge the child), courts are considerably more sympathetic to the claimant. The child is a victim of the estrangement rather than a cause of it; (3) Mutual estrangement or unclear fault: many family estrangements are complex — partial fault on both sides, long histories of family dynamics, different perceptions of the same events. Courts look at the totality of evidence; (4) Length of estrangement alone is not determinative: in Ilott v Mitson, 26 years of estrangement did not bar the claim entirely. The length of estrangement is relevant to the extent of any ongoing mutual relationship and the reasonableness of the parent's exclusion, but it does not automatically defeat the claim; (5) The letter of wishes: a clearly written contemporaneous account of the parent's perception of why the relationship broke down is the most direct evidence the court can receive of the parent's reasoning. It should be factual, not abusive, and witnessed by a responsible person (often the solicitor who drafted the will) to confirm it was written voluntarily.
What is the time limit for an estranged child to make an Inheritance Act 1975 claim?▼
The time limit for an Inheritance Act 1975 claim is 6 months from the date of the grant of probate (or letters of administration if there is no will), under s.4 of the 1975 Act: (1) The clock starts from the grant, not from death: if probate is delayed (which can be months or years in complex estates), the 6-month period does not begin until the grant is issued. An estranged child who knows of the death should monitor when the grant is issued — it becomes a public document at the Probate Registry; (2) Late applications require court permission: the court has discretion under s.4 to allow a late application, but this discretion is exercised narrowly. Good reasons for late applications include: the claimant did not know of the death until after the 6-month period expired; the claimant was themselves suffering incapacity; negotiations were ongoing near the deadline. The fact that the estate has already been distributed is a significant obstacle to a late application (Re Salmon [1981]); (3) Executor's protection: the personal representative is entitled to distribute the estate after 6 months from the grant without waiting for the possibility of a claim. However, if the executor has received notice that a potential claimant may bring a claim, or if a claim has been threatened, distribution before resolution is very risky — the executor can become personally liable; (4) Notice of potential claim: a solicitor acting for a potential IA 1975 claimant will typically serve a formal letter before action on the executors within the 6-month period and issue a claim form to stop the clock. The executor should not distribute pending resolution of any threatened or issued claim; (5) Interim orders: the court can make interim orders under IA 1975 s.5 pending the determination of the claim — preserving assets pending final hearing.
