What Happens If You Die Without a Will in the UK? The Intestacy Rules Explained

If you die without a will in the UK, the intestacy rules automatically determine who inherits your estate — and the outcome is often very different from what you would have wanted. Your unmarried partner receives nothing, regardless of how long you were together. Your children may not be raised by the person you would have chosen. Your business shares pass to family members who may have no interest in running it. The intestacy rules exist as a legal default — they are nobody's personalised plan.

What "Dying Intestate" Means

Dying intestate simply means dying without a valid will. In England and Wales, the rules that govern what happens next are set out in the Administration of Estates Act 1925, updated most recently in 2014. Scotland and Northern Ireland have separate but broadly similar frameworks.

Intestacy is not rare. Surveys consistently show that around half of UK adults have no will in place. The legal system doesn't pause for grief or assess what the deceased would have wanted — it applies the statutory formula, distributes the estate accordingly, and moves on. For a complete guide to how to write a will in the UK — and what it must contain to be legally valid — see our dedicated guide.

The result can be deeply unfair. Long-term partners left with nothing. Children from previous relationships treated differently from children of the current marriage. Businesses disrupted at the worst possible moment. Families left disputing an outcome nobody chose.

The UK Intestacy Rules in Detail

The intestacy rules distribute your estate in a strict order of priority. Here is how it works in England and Wales:

If you are married or in a civil partnership with no children:

Your spouse or civil partner inherits everything.

If you are married or in a civil partnership with children:

Your spouse or civil partner receives your personal possessions and the first £322,000 of your estate. Anything above that threshold is split: half goes to your spouse, half is divided equally between your children. If your children are minors, their share is held in trust until they turn 18.

Example: You are married with two children. Your estate is worth £600,000. Your spouse receives your personal belongings and the first £322,000. The remaining £278,000 is split — £139,000 to your spouse, £69,500 to each child (held in trust until age 18). This may not be what you intended. Your spouse may have needed access to the full estate.

If you have children but are not married:

Your children inherit the entire estate in equal shares. Your partner — regardless of how long you have lived together — receives nothing.

If you have no children and are not married:

The rules escalate through a hierarchy: parents first, then siblings, then half-siblings, then grandparents, then aunts and uncles, then half-aunts and half-uncles. If no relatives can be found at any of these levels, the estate passes to the Crown — known as bona vacantia.

This fixed hierarchy does not account for your actual relationships. A sibling you haven't spoken to in twenty years may inherit before a close friend who has been by your side for decades.

What the Rules Mean for Unmarried Partners

This is the section that shocks people most.

Under UK intestacy rules, an unmarried partner — regardless of how long you have been together, how many children you share, or how completely your finances are intertwined — inherits nothing.

Not a reduced share. Not a life interest in the family home. Nothing.

The law does not recognise the concept of a "common law spouse." It does not exist in England and Wales. You are either legally married, in a civil partnership, or you are a stranger to each other as far as the intestacy rules are concerned.

This means if you die without a will:

• Your partner of 15 years may be required to move out of the family home
• Your children may inherit everything while your partner has no financial security
• Your partner may have to bring a legal claim under the Inheritance (Provision for Family and Dependants) Act 1975 — a process that is expensive, uncertain, and emotionally devastating during an already devastating time

If you are in a long-term unmarried relationship, the absence of a will is not a minor administrative gap. It is a serious risk to the person you have built your life with.

What Happens to Your Children

If you die without a will and both parents are gone, there is no legal document naming who should raise your children. In the absence of a named guardian in a will, the courts must decide — and they will apply their own assessment of what is in the children's best interests, which may not align with your own.

This is not a theoretical concern. It is one of the most emotionally weighty consequences of dying intestate, and it is entirely avoidable.

A will allows you to name a guardian — the person you trust to raise your children, in the way you would want them to be raised. Without one, that decision passes to the court. Extended family members may apply for guardianship. Competing applications may be contested. Your children, in an already catastrophic situation, may face further uncertainty about where they will live and who will care for them.

If you have minor children, the absence of a will is not something to think about later. It is urgent.

What Happens to Your Business

If you own shares in a company and die intestate, those shares become part of your estate and pass under the intestacy rules. The people who inherit them are determined by the same formula — your spouse first, then your children, then the rest of the hierarchy.

The problem is that the people who inherit your shares may have no interest in running the business, no understanding of what it does, and no relationship with your co-founders, employees, or clients. Under most shareholders agreements, a transfer of shares to someone outside the existing shareholders triggers pre-emption rights — other shareholders may have the right to buy out the incoming family member.

This means your family may be forced to sell your stake in the business, potentially at an unfavourable price, at exactly the moment they are least equipped to negotiate.

If there is no shareholders agreement, the situation is worse. A family member may find themselves holding shares in a business they cannot influence and cannot easily exit. Disputes between the family and surviving shareholders can become entangled in probate proceedings, stalling both the estate administration and the business itself. The executor named in the will would be responsible for dealing with these shares — another reason to ensure both documents are clear and consistent.

You can read more about how a shareholders agreement protects against this scenario in detail.

The Emotional and Financial Cost of Dying Intestate

Administering an intestate estate takes longer and costs more than administering an estate with a valid will.

Probate delays. Letters of Administration must be obtained from the Probate Registry before anyone can deal with the estate. This process requires documentation, potential court appearances, and waiting times that regularly stretch to six months or longer for complex estates. Assets can be frozen during this period. Our guide to probate in the UK explains the full process and how a family trust can help you avoid it.

Family disputes. Intestacy removes the one document that could have settled disagreements before they arose. When the estate distribution is determined by a formula rather than a clear expression of wishes, disputes between family members — over assets, over guardianship, over fairness — become more likely. These disputes are expensive to resolve and destructive to family relationships at an already difficult time.

Legal costs eating the estate. Claims under the Inheritance Act, disputes between beneficiaries, contested probate applications — all of these reduce the size of the estate available to your family. The legal fees involved in resolving intestacy disputes can be substantial.

Lasting power of attorney gaps. An intestate estate is often accompanied by a missing lasting power of attorney. If you lose mental capacity before you die, and there is no LPA in place, your family may need to apply to the Court of Protection for a deputyship order to manage your affairs. This is slower, more expensive, and more intrusive than having an LPA already in place.

How to Avoid Intestacy: Your Options

You have three realistic routes.

Write a will yourself. DIY will kits are available and some simple estates can be dealt with this way. The risks are real: an incorrectly signed will is invalid, unclear wording creates disputes, and changes in your circumstances (remarriage, new children, new assets) may not be reflected. A DIY will that fails to meet formal requirements leaves your family exactly where you started — with intestacy.

Use a solicitor. A qualified solicitor can draft a legally robust will tailored to your circumstances. Costs range from £150 for a basic will to over £1,000 for complex family or business arrangements. For families with trusts, business interests, or complicated beneficiary structures, this is often worth the cost.

Frequently Asked Questions

What are the intestacy rules in the UK?

The intestacy rules are a statutory framework that determines who inherits when someone dies without a valid will. Under the Administration of Estates Act 1925 (as amended), assets pass in a fixed order: spouse or civil partner first, then children, then parents, then siblings, then half-siblings, then grandparents, then aunts and uncles. Unmarried partners, stepchildren, and close friends receive nothing under these rules, regardless of how long you lived together or how central they were to your life.

Does my partner inherit if I die without a will?

No — not if you are unmarried. Under the UK intestacy rules, an unmarried partner has no automatic right to inherit anything from your estate, regardless of how long you have lived together. This applies whether you have been together for 2 years or 20 years. Only a legal spouse or registered civil partner is recognised under the intestacy rules. If you want your partner to inherit, you must make a will.

Who gets my house if I die without a will?

It depends on how your property is owned and your marital status. If you own the property as joint tenants with your spouse or partner, it passes automatically to the surviving owner regardless of intestacy. If you own it as tenants in common, your share falls into your estate and passes under the intestacy rules — meaning your spouse may receive it, or it may be shared with your children if your estate exceeds £322,000. If you are unmarried and the property is in your sole name, your unmarried partner receives nothing.

Can intestacy rules be changed after someone dies?

Yes, in limited circumstances. Beneficiaries who inherit under intestacy can enter into a Deed of Variation within two years of the death to redirect assets to different people — including those who would otherwise have received nothing. This can be useful for tax planning or ensuring a surviving partner is provided for. All beneficiaries who would be affected must agree to the variation, and it must be formally documented.

What if I have children and no will?

If you are married with children and die intestate, your spouse receives your personal belongings and the first £322,000 of your estate. Anything above that threshold is split: half goes to your spouse, half is divided equally between your children (held in trust until age 18 if they are minors). If you are unmarried with children, your children inherit the entire estate in equal shares — your partner receives nothing. If both parents die without a will and without naming a guardian, the court decides who raises your children.
