Dying Without a Will in the UK: Who Inherits Under Intestacy Rules?

Quick answer

When a person dies in England and Wales without a valid will they are said to die intestate. Their estate does not go to whoever they wanted it to go to — it passes according to a fixed legal formula set out in the Administration of Estates Act 1925, as updated by subsequent statutory instruments. That formula prioritises legally recognised family relationships: marriage, civil partnership and blood-ties. It ignores years of cohabitation, informal family arrangements, and verbal promises.

The practical result surprises many families. A partner of twenty years can inherit nothing. A child who was estranged for decades can inherit everything. An elderly parent can inherit a share of an estate that the deceased would never have wanted them to have. Understanding the rules — and why the fix is so straightforward — is one of the most useful pieces of financial planning anyone can do.

The intestacy order in England and Wales

The rules work as a strict waterfall. At each level, if there is a surviving relative in that category, the estate stops there (subject to the spouse rules below). Only if there is no one in that category does the estate pass down to the next level.

If you die with no surviving relatives at all, your estate passes to the Crown as bona vacantia — it becomes government property. This is rare but it happens, particularly with older people who outlived their family.

The statutory legacy: when there is a spouse and children

The most common intestacy situation is someone who dies married with children. The rules here are more nuanced than a simple “spouse gets everything.”

Your spouse or civil partner receives:

1. All personal chattels — physical possessions such as furniture, jewellery, vehicles and household items — without limit.
2. A statutory legacy of £322,000 from the remaining estate, absolutely (owned outright, not as a life interest).
3. Half of whatever remains above £322,000.

Your childrenshare the other half of the excess equally. If a child has predeceased you but left children of their own, those grandchildren step into their parent's share (issue taking per stirpes).

Worked example — Ahmed, 52, Manchester

Ahmed dies intestate. His estate comprises: the family home valued at £480,000, held as tenants in common so his 50% share is £240,000; savings of £180,000; personal possessions worth £15,000. Total estate: £435,000.

This may not be what Ahmed would have wanted. It also creates a complication: the children's £56,500 must be held on trust until they turn 18, requiring ongoing legal administration. A simple will leaving everything to Fatima would have avoided all of this.

Spouse with no children

If you die intestate with a surviving spouse or civil partner but no children, they inherit your entire estate absolutely. This is simpler — but still not necessarily what you would have wanted, particularly if you had a preference that some assets go to your own family, siblings, or a specific person.

The position of cohabiting partners

This is the most important — and most poorly understood — aspect of the intestacy rules.

Cohabiting partners have no legal right to inherit under intestacy in England and Wales. None. There is no qualifying period. Living together for 40 years does not create a right. Having children together does not create a right for the partner (the children may inherit, but not the parent). Owning a home together as tenants in common does not create a right beyond the share already owned.

The only automatic protections available to a cohabiting partner are:

• Joint tenancy survivorship— if the property is held as joint tenants, the survivor inherits the deceased's share by operation of law.
• Nominated pension beneficiaries — pension pots pass outside the estate to whoever is nominated; a cohabiting partner can be nominated.
• Life insurance in trust — a policy written in trust can pay out to a named beneficiary, also outside the estate.

For everything else, a cohabiting partner is treated as a legal stranger. Their only recourse is to make a claim under the Inheritance (Provision for Family and Dependants) Act 1975, which allows a court to make reasonable financial provision where someone was financially dependent on the deceased. But this is expensive litigation, takes years, and the outcome is uncertain. It is not a substitute for a will.

Step-children, unmarried parents, and other common situations

Step-children (not legally adopted)

Step-children have no right to inherit under intestacy unless they were legally adopted. A step-parent who raised a child from infancy but never formally adopted them cannot leave them anything under intestacy — the estate passes to biological relatives instead. Only legal adoption changes this.

Separated but not divorced spouses

Legal separation does not dissolve a marriage. If you are separated from your spouse but not yet divorced, and you die intestate, your spouse can still inherit under the intestacy rules as if nothing had changed. Divorce ends the legal marriage and removes the intestacy right; separation does not. This is a powerful reason to either make a will or proceed to formal divorce rather than remaining indefinitely separated.

Adopted children

Legally adopted children are treated exactly the same as biological children for intestacy purposes. They share equally in the estate.

When intestacy meets inheritance tax

Intestacy and inheritance tax interact in ways that can increase the tax bill compared to a thoughtful will.

The key issue is the spousal exemption. Transfers to a spouse or civil partner are completely exempt from inheritance tax. Under a well-drafted will, many couples structure their estates to take maximum advantage of this exemption and to preserve the transferable nil-rate bands. But if the estate passes partly to children under the intestacy rules, that children's share does not benefit from the spousal exemption — it is taxable above the nil-rate band at 40%.

Additionally, the Residence Nil-Rate Band (RNRB) of up to £175,000 applies when a main home passes to direct descendants. Under intestacy, the home may pass partly to a spouse and partly to children, which can create complexity around whether and how the RNRB applies. A tailored will can ensure the home is structured to capture the full allowance.

Scotland's intestacy rules: the key differences

Scotland has its own succession law under the Succession (Scotland) Act 1964, which differs significantly from England and Wales.

Prior rights give a surviving spouse or civil partner:

• The dwellinghouse up to £473,000.
• Furniture and plenishings up to £29,000.
• A financial provision of up to £89,000 if there are children, or £50,000 if there are none.

Legal rights (ius relictae/ius relicti for spouses, legitim for children) give a one-third or one-half share of the net moveable estate. Legal rights cannot be defeated by a will — they represent the irreducible entitlement of a spouse and children even where a will tries to exclude them.

Cohabiting partners in Scotland have a limited additional protection under the Family Law (Scotland) Act 2006: a surviving cohabitant can apply to court within six months of the death for a capital sum from the estate. This is still not automatic and is weaker than the rights of a married partner, but it is stronger than the position in England and Wales.

How to avoid intestacy: making a will

The fix is straightforward. A basic will can be drafted for as little as £150–£300 with a solicitor, or less with an online service for simple estates. The cost of not having one is measured in family disputes, avoidable tax bills, and years of legal administration.

Key things a will should cover:

• Who inherits what — and in what proportions.
• Guardianship of minor children — if you have children under 18, a will is the only place to name a guardian.
• Executor — the person responsible for administering the estate. Without a named executor, the court appoints an administrator, which takes longer and costs more.
• Specific legacies — particular items you want to go to particular people.
• Trusts for minors — if leaving assets to children, you may want them held on trust until a specific age rather than handed over at 18.

A will should be reviewed whenever your circumstances change: marriage (which revokes any existing will in England and Wales), divorce, the birth of children, or major changes in assets.

A practical planning checklist

1. Check how your property is held — joint tenants (survivorship applies) or tenants in common (share passes through estate)?
2. Check your pension nominations — pension funds are outside the estate; make sure the nomination form is up to date.
3. Check your life insurance — is it written in trust? If not, the payout forms part of your estate.
4. Make a will — or review the existing one if circumstances have changed.
5. Estimate your estate value and model any IHT exposure with the calculators below.
6. Consider a Lasting Power of Attorney at the same time — a will only takes effect on death; an LPA protects you if you lose capacity while alive.
