When someone dies without leaving a valid will, the question of who is entitled to their estate can feel overwhelming for those left behind. In England and Wales, there is a clear legal framework that determines how an estate must be distributed in these circumstances. Understanding the intestacy rules can help families navigate a difficult time with greater clarity.

This guide explains what happens if you die without a Will, who can inherit under the rules of intestacy, who is excluded, and what steps to take when someone dies intestate.

What does it mean to die without a Will?

Dying without a valid Will is known legally as dying intestate. When this happens, the deceased's estate, including property, savings, investments and personal possessions, cannot be distributed according to any personal wishes, because no legally binding document records those wishes. Instead, the estate is distributed in accordance with a fixed set of legal rules known as the rules of intestacy, set out in the Administration of Estates Act 1925.

These intestacy rules apply automatically, leave no room for discretion, and determine both who inherits and in what proportions. Understanding what intestacy means is the first step for any family facing this situation.

Intestacy can also arise where a Will exists but is found to be invalid, for example, because it was not properly witnessed or was made under undue influence. In these cases, the estate is treated as though no will exists and the intestacy rules apply in exactly the same way. This is what is meant by the law of intestacy in practice.

Who inherits under the rules of intestacy?

The rules of intestacy establish a strict order of priority. Those higher up the list inherit before those further down, and if a category of relatives exists, those below them receive nothing. This is the foundation of intestate succession in England and Wales.

The order of priority under the law of intestacy is as follows:

• Spouse or civil partner
• Children (including adopted children)
• Parents
• Brothers and sisters (or their children if they have died)
• Half-brothers and half-sisters (or their children if they have died)
• Grandparents
• Aunts and uncles (or their children if they have died)
• Half-aunts and half-uncles (or their children if they have died)

If none of these relatives survive the deceased, the entire estate passes to the Crown, known as bona vacantia. This is a fundamental aspect of no Will inheritance that many people do not realise.

What does a spouse or civil partner inherit?

A surviving spouse or civil partner is given the highest priority under the intestacy rules, but the amount they inherit depends on whether the deceased also had children.

If there are no surviving children or other direct descendants, the spouse or civil partner inherits the entire estate, including all property, savings and personal possessions. If there are surviving children, the position is more complex. The spouse or civil partner receives all personal possessions, a fixed statutory legacy of 322,000 pounds, and half of whatever remains above that threshold. The other half is divided equally among the children.

The spouse or civil partner must survive the deceased by at least 28 days in order to inherit under the intestacy rules. A formal marriage or civil partnership is required, and where divorce proceedings were ongoing at the date of death, the outcome will depend on the specific circumstances.

What do children and grandchildren inherit?

Where there is no surviving spouse or civil partner, children inherit in equal shares regardless of age, with any minor child's share held on trust until they turn 18. Where there is a surviving spouse, children share equally in half of whatever remains after the £322,000 statutory legacy has been paid.

Grandchildren do not inherit directly unless their parent has predeceased the deceased, in which case they step into their parent's share and divide it equally between them. This process is known as inheritance by representation and is a key feature of intestate succession.

Adopted children are treated in exactly the same way as biological children under the intestacy rules in the UK and have full inheritance rights. Stepchildren, however, have no automatic right to inherit unless they were formally and legally adopted by the deceased.

This is one of the most significant reasons why making a Will is so important for blended families, where the people you wish to provide for may otherwise have no legal entitlement at all under no Will inheritance rules.

Who cannot inherit under intestacy rules?

The intestacy rules are strict, and a number of people commonly assumed to be entitled may find they have no automatic right to inherit when there is no Will. Those excluded include:

• Unmarried partners and cohabitants, regardless of how long they lived together
• Stepchildren who were not legally adopted
• Friends and carers
• Estranged family members who may have been informally cut off by the deceased

The exclusion of unmarried partners is one of the most significant gaps in the rules of intestacy. A couple who lived together for decades may have no legal entitlement to each other's estate unless a Will is in place. This is sometimes referred to as the myth of the common law spouse, a concept that has no legal standing in England and Wales.

Those who are excluded from no Will inheritance may, in certain circumstances, be able to make a claim under the Inheritance (Provision for Family and Dependants) Act 1975.

This legislation allows certain categories of person, including those who were financially maintained by the deceased, to apply to the court for reasonable financial provision from the estate. These applications are subject to strict time limits, so prompt legal advice is essential.

Can cousins inherit under an intestacy UK?

A question that arises frequently is whether cousins can inherit under an intestacy UK. Under the standard order of priority set out in the intestacy rules, cousins are not specifically listed as a recognised category.

However, cousins may inherit in certain circumstances as the children of aunts and uncles, since if an aunt or uncle has died before the deceased, their children (the deceased's cousins) can step into their parent's share through inheritance by representation. If you believe you may have a claim as a cousin, specialist legal advice should be sought promptly.

What happens if there are no living relatives?

If the deceased has no surviving relatives within the categories recognised by the intestacy rules, the entire estate passes to the Crown as bona vacantia. This is handled by the Treasury Solicitor's office in England and Wales.

The estate is advertised and, if no eligible relatives come forward within a set period, the assets are retained by the Crown. Estranged or previously unknown relatives can make a formal claim, and the Treasury Solicitor's office will investigate such claims. However, time limits apply and the process can be complex, so specialist legal advice should be sought promptly if you believe you may have a claim under the laws of intestacy.

What should you do if someone has died without a Will?

When someone dies intestate, the estate must still be collected, valued and distributed. The practical steps involved in administering the estate under the intestacy rules include:

• Establishing that no valid Will exists
• Identifying the closest living relatives and determining who is entitled to act
• Applying to the Probate Registry for a grant of letters of administration
• Valuing all assets and liabilities
• Settling outstanding debts
• Distributing what remains in accordance with the intestacy rules

The person authorised to deal with the estate in these circumstances is known as an administrator, rather than an executor.

Administering an estate without a Will and navigating dying intestate can be more complex and time-consuming than when a Will is in place, particularly where property is involved, the estate is large, or family relationships are complicated. Seeking professional legal advice early in the process can prevent costly mistakes and ensure the estate is dealt with correctly.

Does a spouse automatically inherit everything if there is no Will?

Not necessarily. If there are no children or other direct descendants, the surviving spouse or civil partner inherits the entire estate. If there are children, the spouse receives personal possessions, the £322,000 statutory legacy, and half of whatever remains above that amount.

The children share the other half equally. It is a common misconception that a spouse automatically receives everything, which is one of the key reasons having a will is so important. Understanding who inherits when there is no Will can help families plan appropriately.

Can unmarried partners inherit under intestacy rules?

No. Unmarried partners have no automatic right to inherit in England and Wales, regardless of how long they lived together or whether they had children together. This is one of the most important things to understand about dying without a Will.

An unmarried partner may be able to make a claim under the Inheritance (Provision for Family and Dependants) Act 1975 in certain circumstances, but specialist legal advice should be sought quickly as strict time limits apply.

Do stepchildren have any inheritance rights under intestacy?

Stepchildren have no automatic right to inherit unless they were legally adopted by the deceased. Informal arrangements, however longstanding, do not create a legal entitlement under the rules of intestacy. This is one of the most important reasons why anyone with stepchildren should make a Will, so that those children can be properly provided for.

Can you challenge the intestacy rules?

The intestacy rules cannot be challenged in the same way as a disputed Will. However, certain people, including spouses, unmarried partners who lived with the deceased for at least two years before their death, children, and others who were financially maintained by the deceased, may be able to apply under the Inheritance (Provision for Family and Dependants) Act 1975. Strict time limits apply to these applications.

What is intestacy and how does it arise?

Intestacy is the legal status of an estate when the deceased has died without a valid Will, or where a Will exists but has been found to be invalid. When intestacy arises, the intestacy laws of England and Wales determine how the estate is distributed, following the fixed order of priority described above. Anyone who wants to control what happens to their estate should make a clear and legally valid Will.
