⚡ Quick answer: You can write your own Will, but it must comply with the Wills Act 1837. One signing error, one wrong witness, or one ambiguous sentence can make the whole document worthless — and your estate passes under intestacy rules instead.
The Legal Requirements for a Valid Will in England & Wales
Under the Wills Act 1837, a Will is only legally valid if all of the following conditions are met:
- You are 18 years of age or over (or 16 if serving in the armed forces)
- You are of sound mind (testamentary capacity) at the time of signing
- The Will is in writing — typed or handwritten
- You sign the Will in the presence of two witnesses simultaneously
- Both witnesses sign in your presence immediately after you do
- The witnesses are both over 18 and mentally capable
- Neither witness is a beneficiary (or married to one)
Miss any one of these requirements, and the Will — or part of it — may be declared invalid.
Are Handwritten (Holographic) Wills Valid?
⚠️ No. Unlike Scotland, the USA, and many other countries, handwritten "holographic" wills are not valid in England and Wales. Even a handwritten Will must still be properly signed and witnessed under the Wills Act 1837. Writing a Will entirely in your own hand without witnesses does not make it legally binding here.
The Most Common DIY Will Mistakes
Thousands of DIY wills are challenged or declared invalid each year. The most frequent reasons:
| Mistake | Consequence |
|---|---|
| Witness is a beneficiary (or their spouse) | Gift to that beneficiary is void — they receive nothing |
| Both witnesses not present simultaneously | Entire Will may be invalid |
| Ambiguous wording ("my jewellery to my daughters") | Family dispute; court decides |
| No residuary clause | Leftover assets fall under intestacy rules |
| Forgot to update after marriage | Marriage automatically revokes the old Will |
| Alterations after signing | Changes not signed/witnessed are invalid |
| Named executor has predeceased | Court appoints someone — delays and costs |
What Happens If Your DIY Will Is Invalid?
If your Will is found to be invalid, your estate is distributed as if you had no Will at all. This means the intestacy rules apply:
- Unmarried partners receive nothing under intestacy, regardless of how long you lived together
- Stepchildren are not automatically entitled to inherit
- Specific gifts to friends or charities are lost
- Your estate may pass to distant relatives you never intended to benefit
Your family may also face a lengthy and expensive legal process to resolve the situation.
DIY Will vs Professional Will: The Real Comparison
| DIY Will | Clear Legacy Will | |
|---|---|---|
| Cost | £0 (template) or £10–£30 (kit) | From £69 (single) / £99 (mirror) |
| Legal review | None | Expert-reviewed |
| Risk of errors | High | Low |
| Witness guidance | You figure it out | Included |
| Covers edge cases | Rarely | Yes (residuary clause, guardians, etc.) |
| Legally challenged | Far more likely | Professionally drafted — robust |
| Peace of mind | Uncertain | High |
The difference between a free DIY Will and a £69 professionally drafted one is not the piece of paper — it's the certainty that your wishes will actually be carried out.
When Writing Your Own Will Might Be Acceptable
A DIY Will could be adequate if your situation is genuinely simple: you have one spouse, no children from previous relationships, no property, no business interests, and a modest estate that falls well below the Inheritance Tax threshold (£325,000). Even then, careful attention to the witnessing rules is essential.
For anyone with property, children, an unmarried partner, a blended family, or assets of any significance — the risk of a DIY Will is not worth taking.
What About Will Writing Kits?
Newsagent or stationery shop Will kits provide blank forms with basic instructions. They are marginally better than writing from scratch, but still carry the same risks: they cannot account for your specific circumstances, and errors in completion are common. They provide no legal review and no guarantee of validity.

Can I type my Will on a computer and print it?
Yes. A typed and printed Will is perfectly valid provided it is signed and witnessed correctly. There is no requirement for a Will to be handwritten — and typed Wills are generally clearer and less ambiguous.
Does a Will need to be witnessed by a solicitor?
No. Any two adults who are not beneficiaries (and are not married to beneficiaries) can witness your Will. Friends, neighbours, or colleagues are all acceptable. You do not need a solicitor to act as a witness.
What if I want to change my Will after writing it?
Do not cross out or amend a signed Will — any changes made after signing must be done by a separate document called a codicil, signed and witnessed in the same way as the original Will. In most cases, it's simpler and safer to write a new Will entirely.
