Your partner of 20 years gets nothing.
Your estranged cousin—the one you haven’t spoken to since that argument at a wedding in 2009—inherits your house.
Your children are placed with a guardian chosen by a court, not by you.
This isn’t a dystopian novel. It’s not a hypothetical. It’s what happens when you die without a Will in the United Kingdom in 2026.
The government has already written your Will. You just haven’t read it yet.
The Default You Didn’t Choose
Here’s something most people don’t realise: there’s no such thing as dying “without a Will.”
If you don’t write one, the state writes one for you. It’s called intestacy. And the rules governing it were drafted in 1925—before cohabitation was common, before digital assets existed, before a semi-detached house in the Home Counties could be worth more than a Mayfair flat was a century ago.
The Administration of Estates Act 1925 doesn’t care about your intentions. It doesn’t care that you’ve lived with your partner for 18 years, raised children together, and consider yourselves “basically married.”
It cares about one thing: what’s on paper.
And if nothing’s on paper, your wishes are irrelevant.
The Case of John and Mary
Let me tell you about a couple I’ll call John and Mary.
They met in their late thirties. Both had been married before—briefly, unhappily. They decided they didn’t need another piece of paper to prove their commitment. They bought a house together (in John’s name, for mortgage reasons). They raised two children. They renovated the kitchen. They nursed each other through illness.
Eighteen years passed.
Then John died. Suddenly. A heart attack at 59.
Mary, understandably devastated, assumed she’d inherit the house. The house she’d lived in for nearly two decades. The house where she’d raised her children.
She was wrong.
Under intestacy rules, unmarried partners have no automatic inheritance rights. None. The house passed to John’s next of kin: his brother. A man who lived in Australia. A man John hadn’t spoken to in a decade.
Mary found herself in the surreal position of having to ask permission to remain in her own home.
She fought back. She hired solicitors. She invoked the Inheritance (Provision for Family and Dependants) Act 1975—a legal route that allows people who were financially dependent on the deceased to make a claim.
The process took three years.
It cost £80,000.
She won a partial settlement.
A 30-minute conversation and a £150 document could have prevented all of it.
The Default Effect
Behavioural economists have a name for what happened to John and Mary. They call it the Default Effect.
Humans are pathologically passive. When no active choice is made, we accept whatever default is presented—even when it actively harms us.
This is why pension auto-enrolment works. Most people don’t choose to save for retirement; they simply don’t choose not to. The default does the heavy lifting.
It’s why countries with opt-out organ donation have dramatically higher transplant rates than countries with opt-in systems. People don’t oppose donating organs; they just don’t get around to ticking the box.
And it’s why 56% of UK adults die without a Will.
Not because they decided intestacy was the right path. Not because they examined the rules and thought, “Yes, I’d like my estranged relatives to benefit and my partner to get nothing.”
They just… didn’t get around to it.
The default won.
The Comfortable Lie
You’re reading this thinking: That won’t happen to me.
Maybe you’re married. Maybe you assume your spouse gets everything.
Here’s the uncomfortable truth: they don’t.
If you die intestate and you’re married with children, your spouse gets the first £322,000 of your estate, your personal possessions, and half of the remainder. The other half goes directly to your children.
Sounds reasonable?
Now imagine your estate is a £900,000 house (not unusual in the South East) with £50,000 in savings. Your spouse gets £322,000 plus £314,000 (half of the remaining £628,000). The children get £314,000.
But here’s the catch: that £314,000 belonging to the children might be locked in the equity of the family home. Your spouse may be forced to sell—or mortgage—the house to release the children’s inheritance.
Forced to sell the family home. To give money to your own children. Who probably don’t want it right now anyway.
This is the “default” the government has written for you.
The Numbers That Should Alarm You
Only 44% of UK adults have a Will.
Among cohabiting couples—those most exposed to intestacy’s cruelest outcomes—it’s closer to 30%.
The average cost of a contested probate case exceeds £25,000.
The Nil-Rate Band for Inheritance Tax has been frozen at £325,000 since 2009. Thanks to property inflation, millions of middle-income families are now exposed to a 40% tax bill that was once reserved for the wealthy.
And from April 6, 2027, unused pension funds will be included in your taxable estate for the first time. That pot you’ve been carefully preserving? It’s about to become a 40% gift to HMRC.
The defaults are not in your favour.
A Confession
I should tell you something.
I’m a doctor. I spend my working life helping people prepare for worst-case scenarios. I’ve had difficult conversations about prognosis, about resuscitation, about what happens when things go wrong.
And I nearly didn’t prepare for my own.
I had the same excuses you do. I’m young enough. I’m healthy. I’ll get around to it. There’s always next month.
It wasn’t until a colleague—younger than me, fitter than me—collapsed at work that I finally sat down and did it. A Will. Two LPAs. A letter of wishes. A document explaining where to find my passwords.
It took a Saturday afternoon.
The hardest part wasn’t the paperwork. It was admitting that I’m not exempt from the same mortality I counsel others about every day.
The Action Plan
Here’s what you can do this weekend. Not next month. This weekend.
1. Audit Your Estate
Most people underestimate their net worth by 30-40%.
List everything: property (current value, not purchase price), pensions, ISAs, savings accounts, life insurance, business interests, crypto holdings, valuable possessions, digital assets with monetary value.
Add it up. If the number exceeds £325,000, you’re in IHT territory. If it exceeds £500,000 and includes a residence passing to direct descendants, you may qualify for the additional £175,000 Residence Nil-Rate Band—but only if you’ve planned for it.
2. Write a Will
This is simpler than you think.
For straightforward estates, online services like Farewill or Co-op Legal Services cost £90–£150. You answer questions, they draft the document, you print and sign it in front of two witnesses.
If your affairs are complex—trusts, business assets, blended families, properties abroad—spend £300–£500 on a solicitor. It’s still cheaper than a single hour of probate litigation.
Either way, it’s done in an afternoon.
3. Register Lasting Powers of Attorney
Don’t wait until you “need” one.
Here’s a number that should unsettle you: UK healthy life expectancy is approximately 64 years. That’s the age at which the average person’s health begins to decline. Not 85. Not 75. 64.
By the time cognitive decline becomes obvious, it’s often too late to sign legal documents. The window for mental capacity is smaller than you think.
An LPA costs £82 per type to register. There are two types: Property and Financial Affairs (covers your money) and Health and Welfare (covers your medical decisions). You want both.
Do it now, while you still find the suggestion insulting.
4. Seek Regulated Financial Advice.
At Building Out, we are all about helping people understand financial decisions through education rather than advice. Normally, you will get a disclaimer at the bottom for me telling you this is education, not advice. Often people with the right education can make good financial decisions.
However, this is an area where I would very strongly recommend that you seek financial advice. If you are likely to have a problem with inheritance tax or need to set up a will or a trust,getting sound financial advice is, for me, the only way forward. These are sometimes very complex areas, and you need to get proper financial advice to protect yourself.
The GPS Analogy
Think of estate planning as programming a GPS for your family’s future.
If you don’t input the coordinates—a Will, LPAs, clear records—the government will use the “default route.” Intestacy.
That route includes expensive toll roads (Inheritance Tax at 40%), unexpected detours (years of probate litigation), and often ends at a destination you never intended (estranged relatives, forced property sales, court-appointed guardians for your children).
The vehicle will still arrive somewhere.
You just won’t like where it parks.
The Final Thought
A Will isn’t about death.
It’s about control. It’s the last act of autonomy over your own life. The final decision you get to make about who benefits from your decades of work.
The alternative is to hand that decision to a 99-year-old law, a government that doesn’t know your family, and a probate system that charges by the hour.
You’ve spent years building something. A career. A family. A legacy.
Don’t let the default destroy it.
