Nobody likes thinking about death. It feels uncomfortable, it feels far off, and something more urgent always seems to come up first. So writing a will gets pushed to the bottom of the list, year after year, until something happens and you wish you had sorted it sooner.
Here is the reality. According to research from the Money and Pensions Service published in January 2025, 56% of UK adults aged 18 and over do not have a will. That is the majority of people leaving one of the most important financial decisions entirely in the hands of the law rather than their own. If you are one of them, here is exactly what happens to your money when you are gone.
What Does Dying Without a Will Actually Mean?
When you die without a valid will in place, you are said to have died intestate. Your estate is then distributed according to the rules of intestacy, which means you have no control over who inherits your assets. It does not matter how clear your wishes were in life, how many conversations you had with family, or how obvious you thought the arrangement was. None of that counts legally. The government has a set formula, and that formula is what gets applied.
The Intestacy Rules: Who Actually Gets What
The rules work in a strict order of priority, and they throw up some genuinely surprising outcomes for a lot of families.
If you are married or in a civil partnership with no children, your spouse inherits everything. Straightforward enough. But if you have children and your estate is worth more than £322,000, things get considerably more complicated. Your spouse or civil partner receives all personal belongings plus the first £322,000 of the estate, and then half of anything above that threshold. The other half is divided equally between your children. If your estate is worth less than £322,000, your spouse gets everything and your children receive nothing at all immediately.
If you are not married and have no children, your estate passes to your parents. If your parents have already died, it is shared between your siblings. If no eligible relatives can be found at all, your entire estate passes to the Crown. Yes, the government gets it.
The Biggest Myth in UK Personal Finance
Here is the one that catches people out more than anything else. Common law marriage does not exist in the UK — it is a complete myth. Unless you are married or in a civil partnership, your partner has no automatic right to inherit anything, regardless of whether you have been together for 5 years or 25.
So if you have lived with your partner for 10, 15 or 20 years and you die without a will, they could be left with nothing. The house, the savings, the investments, everything could pass to relatives you barely speak to while the person you actually share your life with has no legal claim whatsoever. This is not a rare edge case. It happens regularly, and it causes real financial devastation for families at the worst possible moment.
What About Your Kids?
If you have children, intestacy rules do protect them to a degree, but not always in the way you would choose. Stepchildren and foster children are not entitled to anything under intestacy rules unless they were legally adopted by you. So if you have stepchildren you have raised as your own but never formally adopted, they could receive nothing while biological relatives you are estranged from inherit instead.
There is also the issue of age. If your children are minors when you die intestate, their inheritance is held in a trust until they turn 18. You have no say in how it is managed in the meantime, who oversees it, or any conditions attached to when and how they receive it. A will gives you the option to delay that inheritance past 18 or set conditions around it, which many parents would prefer.
Sorting Out the Estate Is Also Harder Without a Will
Beyond who gets what, dying without a will also makes the administrative process significantly more difficult for the people you leave behind. Without a will, the process of applying for probate becomes more complicated and typically takes considerably longer than when a valid will is in place. Disputes between relatives over who should administer the estate and what they are entitled to are far more common when there is nothing written down to refer to. Legal fees pile up, relationships get damaged, and the whole process drags on for months or years longer than it needs to.
The people you love are left dealing with bureaucracy and potential family conflict at exactly the moment they are grieving. A will does not just protect your money. It protects the people left behind from an enormous amount of unnecessary stress.
What a Will Actually Lets You Do
Writing a will is not just about deciding who gets your money. It gives you a level of control that intestacy rules simply cannot offer. You can leave specific items to specific people. You can set up a trust for your children with conditions attached. You can leave money to friends, a charity, or a cause you care about. You can appoint guardians for your children if they are still young. You can name the executors you trust to handle everything properly rather than leaving it to whoever the law assigns.
You can also use a will as part of your broader inheritance tax planning. The standard nil rate band currently sits at £325,000, meaning anything above that threshold in your estate could be subject to 40% inheritance tax. A well structured will, combined with proper use of available allowances and reliefs, can significantly reduce the tax your family faces. A married couple can potentially pass on up to £1 million completely tax free when both nil rate bands and the residence nil rate band are used correctly. None of that careful planning is possible if you die intestate.
How Much Does Writing a Will Actually Cost?
This is where most people are surprised. A basic will from a solicitor typically costs between £150 and £300. More complex arrangements with trusts or multiple assets cost more, but for most people it is a straightforward and relatively affordable process. Online will services have also made it even more accessible, with reputable providers offering legally valid wills from around £90.
Given what is at stake, the cost of writing a will is minimal compared to the financial and emotional cost of not having one. According to research, one of the biggest reasons people put it off is believing they do not have enough wealth to bother. The irony is that the intestacy rules cause the most damage not to the very wealthy, who tend to have lawyers involved anyway, but to ordinary families with a home, some savings, and a partner they never got around to marrying.
Without a will, the law decides everything, and the outcomes can be brutal for the people you love most. Your partner could be left with nothing while distant relatives inherit instead, and stepchildren you raised could be cut out entirely.
Writing a will takes a few hours and costs very little. It is one of the simplest financial decisions you will ever make and one of the most important. If you have been putting it off, let this be the nudge that finally gets it done.
