If someone dies without leaving a valid will, their estate is distributed under a legal framework known as intestacy. While many people assume their assets will simply pass to their closest family members, the rules of intestacy in the UK can lead to surprising—and sometimes unfair—outcomes.
In this blog, we’ll explore the little-known rules of intestacy in the UK, who inherits under the law, and why making a will is essential.
What Is Intestacy in the UK?
Intestacy in the UK refers to the legal process that determines how a person’s estate is distributed when they die without a valid will. The law follows a fixed hierarchy of relatives, regardless of your personal wishes or family dynamics.
Many people are unaware of how strict and outdated some of these rules can be. Below are some lesser-known facts you should know.
1. Unmarried Partners Are Not Protected
Even if you’ve lived with your partner for decades, unmarried or cohabiting partners have no legal right to inherit under UK intestacy laws. The concept of a “common-law spouse” has no standing in England or Wales.
If you die without a will, your partner could be left with nothing—even if you owned a home together or shared children.
2. Your Spouse May Not Inherit Everything
Under the rules of intestacy in the UK, a surviving spouse or civil partner doesn’t always inherit the entire estate:
-
They get all personal possessions.
-
They receive the first £322,000 of the estate (as of 2023).
-
The remainder is split 50/50 between the spouse and any children.
This can create legal and financial complications, particularly if the estate includes property that cannot be easily divided.
3. Stepchildren Are Excluded
Stepchildren do not inherit under UK intestacy laws unless they’ve been legally adopted. Even if you consider them part of your family, the law does not—unless your will says otherwise.
4. Children Born Outside Marriage Are Equal
A positive update to the law is that all biological children—whether born in or out of marriage—inherit equally. Legally adopted children are also included, but foster children are not.
5. Estranged Relatives Can Still Inherit
The law doesn’t consider personal relationships—only blood and legal ties. That means estranged parents, siblings, or children may inherit your estate, even if you haven’t spoken to them in years.
6. No Surviving Relatives? The Crown Inherits
If no living relatives can be found under the intestacy hierarchy, your estate goes to the Crown through a process called bona vacantia. The government may then use those assets for public benefit.
Close friends, carers, or unmarried partners won’t be entitled to anything without a valid will.
7. Some Assets Aren’t Affected by Intestacy
Not everything is governed by intestacy laws. For example:
-
Jointly owned property (as joint tenants) automatically passes to the surviving owner.
-
Bank accounts in joint names also pass directly to the surviving holder.
-
Life insurance, pensions, and death-in-service benefits often go to named beneficiaries.
However, if these are not carefully set up, they may still form part of your estate and be subject to intestacy.
8. Inheritance Tax Still Applies
Intestacy doesn’t prevent inheritance tax (IHT). If your estate is valued over the £325,000 threshold, IHT may apply at 40% on anything above that amount (with exemptions for spouses and charities).
Making a will allows for better estate planning to reduce this tax burden.
Why You Shouldn’t Rely on Intestacy
While the rules of intestacy in the UK provide a legal safety net, they’re rigid, outdated, and often unfair. They don’t consider your emotional relationships, blended family dynamics, or personal wishes. A simple will ensures:
-
Your partner is protected
-
Your children receive what you intend
-
Tax and legal costs are minimised
-
Stress and conflict are reduced for your loved ones
FAQ: Intestacy in the UK
Q: Who inherits if someone dies without a will in the UK?
A: It depends on the family structure. Spouses and children inherit first, followed by parents, siblings, and more distant relatives. Unmarried partners and stepchildren do not inherit unless named in a will.
Q: What is bona vacantia?
A: If no eligible relatives exist, the deceased’s estate passes to the Crown as bona vacantia.
Q: Can I challenge intestacy outcomes?
A: Possibly. Under the Inheritance (Provision for Family and Dependants) Act 1975, certain people can claim financial provision if they were financially dependent on the deceased.
Final Thoughts
Understanding the rules of intestacy in the UK is essential—especially if you’re in a non-traditional family or relationship. A will gives you control and peace of mind. Without one, your estate could end up in the hands of people you never intended, or worse, the government. If you need assistance with an intestacy case, please contact us.
