If you die without a valid will, your estate is shared according to the Rules of Intestacy — a strict set of legal guidelines laid out in the Administration of Estates Act 1925.
These rules decide who inherits your money, property, and possessions. Unfortunately, they often don’t reflect what most people would actually want.
In simple terms, if you don’t have a will, you lose control over who benefits from your estate, and in some cases, the people you care about most could receive nothing.
What Are the Rules of Intestacy?
The Rules of Intestacy apply to everyone in England and Wales who dies without a valid will. They set out a fixed order of inheritance based on your surviving relatives.
According to the Inheritance and Trustees’ Powers Act 2014, as updated in 2023:
- If you are married or in a civil partnership with no children, your spouse or partner inherits everything.
- If you are married or in a civil partnership and have children, your partner inherits:
- All personal belongings (called chattels).
- A fixed sum of £322,000.
- Half of the remaining estate.
The other half goes to your children equally, or into a statutory trust until they turn 18.
- If you are not married or in a civil partnership, your estate is divided among your children equally.
- If you have no children or grandchildren, inheritance passes to your next relatives in this order:
- Parents
- Brothers and sisters (or their children if they’ve passed away)
- Half-brothers and half-sisters
- Grandparents
- Uncles and aunts (whole blood first, then half blood)
- The Crown (if no surviving relatives)
If you have no living relatives, everything goes to the Crown — the government becomes the ultimate beneficiary.

Who Misses Out Under the Rules?
The rules of intestacy can leave out people who might reasonably expect to inherit. This includes:
- Unmarried partners – Even if you’ve lived together for decades, cohabiting partners have no automatic right to inherit.
- Stepchildren – Only biological or legally adopted children are recognised.
- Friends and carers – These individuals receive nothing unless named in a valid will.
- Charities – If you hoped to leave a donation, it won’t happen without a will.
In short, the law decides who gets what, not you.
Why the Rules Can Cause Problems
The intestacy process can be complicated, stressful, and expensive for families. Without a will:
- Loved ones may need to apply to court for the right to deal with your estate.
- Family disputes can arise, especially in blended families.
- Inheritance tax planning opportunities are lost.
- Assets might go to relatives you barely know, or even to the Crown.
If your family circumstances are anything other than straightforward — for example, if you’re unmarried, have stepchildren, or own a business — relying on intestacy rules is risky.
How to Make Sure Your Wishes Are Followed
Writing a valid will gives you complete control over who inherits your estate and how it’s handled. It also lets you:
- Appoint guardians for your children.
- Choose your executors (the people who will manage your estate).
- Protect vulnerable or disabled beneficiaries using trusts.
- Reduce inheritance tax through careful planning.
You can also make arrangements for business interests or property, which intestacy rules don’t cover properly.

Real Example: Why a Will Matters
Lisa and Mark lived together for 20 years and owned a home jointly. They never married. When Mark died suddenly, his share of the property automatically went to Lisa because it was held as joint tenants.
However, Mark’s personal savings, investments, and belongings were not covered by this. Because he had no will, his estate passed under intestacy rules to his estranged parents — not to Lisa.
Despite two decades together, Lisa had no legal right to his assets. With a simple will, that could have been avoided.
Can Intestacy Be Changed After Death?
Sometimes, the beneficiaries of an intestate estate can agree to change how it’s distributed by signing a Deed of Variation.
This allows them to redirect assets to someone else, such as a partner, child, or charity, within two years of death.
While useful, a Deed of Variation requires agreement from all beneficiaries — which is often difficult when emotions and money are involved. It’s far better to put your wishes in writing while you’re alive.

Final Thoughts
The rules of intestacy are clear, but they’re not kind or flexible. They follow the law, not your personal wishes.
Without a will, the people you care about most could be left with nothing, while others you never intended to benefit could inherit everything.
Writing a will is one of the simplest and most powerful ways to protect your family, secure your legacy, and make sure your estate is passed on the way you want.
