A will template can be legally valid in England and Wales, but the main risk is that a small mistake in wording, signing or witnessing goes unnoticed until after death, when the will cannot be corrected. The most serious errors can make the whole will invalid, so an estate is shared under the intestacy rules instead of following the wishes written down.
The problem is rarely the template itself. It is that a template gives no feedback. There is no one to point out that a witness also stands to inherit, that a gift is described too vaguely to identify, or that a later marriage has cancelled the document entirely. This guide sets out the specific risks of a DIY will for England and Wales, where they tend to bite, and when a template may still be a reasonable starting point. Figures are current as at August 2026 and are subject to change.
Are will templates legal in the UK?
Yes. There is no requirement to use a solicitor or a will writer. A will made on a template, a shop-bought pack or a handwritten sheet is valid so long as it meets the legal formalities: the person making it is 18 or over and of sound mind, it is in writing, it is signed by them in the presence of two witnesses, and each witness then signs in their presence (gov.uk, make your will legal, as at August 2026, subject to change). Legal and effective are not the same thing, though. A will can tick every formal box and still fail to do what its author intended.
The main risks of a will template, at a glance
| Risk | What can go wrong | Likely consequence |
|---|---|---|
| Witnessing error | Only one witness, or a beneficiary or their spouse witnesses it | The will may be invalid, or that person loses their gift |
| Signing error | Signed out of order, or witnesses did not see the signing | The will may be invalid |
| Unclear wording | A gift is ambiguous or a beneficiary cannot be identified | Disputes, part of the will fails, cost and delay |
| Partial intestacy | The will does not deal with the whole estate | Leftover assets pass under the intestacy rules |
| Life changes | Marriage after the will, or an outdated document | The will may be cancelled or no longer reflect wishes |
| Missed tax and structure | No thought given to inheritance tax, trusts or care costs | A larger tax bill or less protection than intended |

Signing and witnessing: the most common template failure
The rules on signing look simple, which is exactly why they are so often broken. A will must be signed by its author in the presence of two witnesses, who must each have a clear view of the signing and then sign themselves (gov.uk, as at August 2026, subject to change). Two errors recur with DIY wills:
- A beneficiary, or their husband, wife or civil partner, acts as a witness. The will can still be valid, but the gift to that beneficiary usually fails, so the very person the will was meant to benefit receives nothing (gov.uk, as at August 2026, subject to change).
- The witnessing is not done properly. Signing before the witnesses arrive, or having them sign in another room, can mean the formalities are not met and the will is invalid.
A template can state these rules in its notes, but it cannot check that they were followed. The gap between reading an instruction and applying it correctly, under stress and often in older age, is where many home-made wills come apart. Our guide on how to write a will walks through the signing steps in more detail.
Unclear wording and part-failed gifts
The second broad risk is language. A template supplies the frame, not the words that describe your family and your assets. Problems arise when a gift is too vague to identify (“my savings” when accounts have since changed), when a beneficiary is named loosely (“the children” without saying whose), or when the will does not say what happens if a beneficiary dies first. If wording is unclear, the estate may need a court's help to interpret it, which brings cost and delay, and a gift that cannot be saved simply fails.
A related trap is partial intestacy. If a will gives away specific items but never deals with everything else, the leftover assets pass under the intestacy rules (gov.uk, as at August 2026, subject to change), which may send them to people the author never intended. Under those rules an unmarried partner inherits nothing, regardless of how long the couple lived together.
A template can be signed perfectly and still say the wrong thing. Valid and clear are two different tests, and both have to be passed.
What a will template cannot do for you
Even a well-drafted DIY will only covers who inherits on death. It does nothing about three areas that often matter as much as the will itself.
- Mental capacity. A will takes effect only on death and does nothing if you lose capacity during life. That is the job of a lasting power of attorney, registered with the Office of the Public Guardian for £92 per document (gov.uk, as at August 2026, subject to change).
- Trusts and vulnerable beneficiaries. Providing for a young child, a disabled relative or children from a previous relationship often needs a trust, which a basic template does not offer.
- Care costs. A template does nothing towards planning for, limiting or mitigating the impact of care fees, an area that needs careful, documented thought rather than a standard form.
Template, will writer or solicitor: the trade-off
Cost is usually why people reach for a template, so it helps to see the choice plainly. Prices below are typical ranges rather than quotes, and vary by provider and complexity.
| Option | Typical cost | Best suited to |
|---|---|---|
| DIY template or online form | Free to around £50 | Very simple wishes, small and straightforward estates |
| Will writer or estate planning specialist | Often £100 to £500+ | Most family situations, some tax and trust needs |
| Solicitor | Often £150 to £650+, more for complex work | Complex estates, disputes, detailed tax or trust planning |
Indicative market ranges for general guidance only, not a quote; costs vary by provider and circumstances, as at August 2026, subject to change.
The saving on a template is real, but it is a saving measured against a cost that only appears later. Putting a badly worded or invalid will right after death, through a deed of variation, a claim or a court application, can cost the estate far more than a professionally prepared will would have. In our experience the estates that run into difficulty are rarely the very simple ones; they are the middling cases where a template looked good enough.
When a will template might be reasonable
A template is not always the wrong answer. For an adult with a simple, low-value estate, no property complications, no business or farm, no children from previous relationships, and everything left to one or two clearly named people, a carefully completed template that follows the signing rules can do the job. The risk rises sharply once any of the following apply.
- You own property, especially jointly, or your estate may face inheritance tax
- You have a blended family, stepchildren, or a partner you are not married to
- You want to protect a gift, provide for a vulnerable person, or use a trust
- You own a business, farm or assets abroad
- You expect anyone might dispute the will
Where more than one of these is present, many people decide the certainty of a properly drafted will is worth the fee. If you are weighing it up, our estate planning guide shows how a will fits alongside tax, trusts and powers of attorney.
Frequently asked questions
Are will templates legal in the UK?
Yes. A will made on a template is valid in England and Wales if the person is 18 or over and of sound mind, the will is in writing, and it is signed in the presence of two witnesses who each then sign it (gov.uk, as at August 2026, subject to change). The risk is not legality but whether the will is signed correctly and worded clearly enough to do what was intended.
What is the biggest risk of a DIY will?
The most common serious risk is a witnessing or signing error, because it can make the will invalid or cause a beneficiary who witnessed it to lose their gift (gov.uk, as at August 2026, subject to change). Unclear wording that leads to disputes or part of the estate passing under the intestacy rules is a close second.
What happens if a will is invalid?
If a will is invalid, the estate is shared under the intestacy rules as though no will existed (gov.uk, as at August 2026, subject to change). Those rules follow a fixed order of relatives and give nothing to an unmarried partner, so the outcome can be very different from what the will set out to achieve.
Can a beneficiary witness a will?
A beneficiary, or their husband, wife or civil partner, can act as a witness, but doing so usually means that beneficiary loses their gift while the rest of the will stands (gov.uk, as at August 2026, subject to change). It is generally safer to use two independent witnesses who do not inherit anything.
Does a will template cover inheritance tax?
No. A template records who inherits but says nothing about tax. Inheritance tax is charged at 40% on the part of an estate above the available thresholds, and how a will is worded can affect whether the residence nil-rate band and reliefs apply (gov.uk, as at August 2026, subject to change). Larger or more complex estates often look at drafting and tax together.
Does getting married cancel a will?
In most cases, yes. Marriage or entering a civil partnership cancels an existing will in England and Wales, unless the will was made in expectation of that marriage or civil partnership (gov.uk, as at August 2026, subject to change). Someone who marries after making a template will, and does not make a new one, may die intestate without realising it.
