Can You Write Your Own Will in the UK? The Honest Answer

The short answer to "can I write my own will?" is yes. There is no legal requirement in England and Wales to use a solicitor or any professional to write a will. A handwritten will — even one written on a single sheet of paper — can be entirely valid, provided it meets the requirements of the Wills Act 1837.

The longer, more honest answer is that most people who write their own wills introduce errors they are not aware of — and those errors only come to light after death, when it is too late to fix them.

What a Valid Will Actually Requires

A DIY will must meet exactly the same legal requirements as one drafted by a solicitor. It must be in writing. The testator must be aged 18 or over and of testamentary capacity. It must be signed by the testator in the presence of two independent witnesses, both present simultaneously, who must then each sign in the testator's presence. The witnesses must not be beneficiaries or married to beneficiaries.

Miss any element and the will is invalid. There are no partial marks.

Where DIY Wills Most Commonly Go Wrong

The signing and witnessing process catches many people out — not because it is complicated, but because the specific simultaneous presence requirement is not intuitive. Witnesses signing at different times, or signing before the testator, invalidates the will even if everything else is perfectly written.

Beyond the formalities, the most frequent substantive errors in DIY wills are:

• No residuary clause — assets not specifically mentioned are not covered, creating partial intestacy
• Ambiguous gifts — unclear descriptions of property or beneficiaries that generate disputes
• No substitute beneficiary — if the named beneficiary predeceases you, the gift lapses with no fallback
• No executor named — or an executor who has already died, leaving the estate without anyone authorised to act
• No guardianship clause — for parents, the single most important omission
• Alterations after signing — any change made after the will is signed and witnessed has no legal effect unless itself signed and witnessed

When a DIY Will Might Be Acceptable

A simple handwritten will may be appropriate if your estate is genuinely minimal — no property, modest savings, no dependants, and a single straightforward beneficiary. Even then, the question worth asking is: what is the cost of getting it wrong versus the cost of getting it right? If the answer to the latter is £19.99, the case for a DIY approach is hard to sustain.

When a DIY Will Is Genuinely Dangerous

For anyone who owns property, has children, has a partner — married or not — has digital assets of value, runs a business, or has any complexity in their wishes, writing their own will without professional guidance creates meaningful risk. Not the risk that it will look wrong — the risk that it will be legally invalid, or valid but ambiguous enough to be challenged.

The consequences of an invalid or contested will fall entirely on the people you were trying to protect. They face contested probate, potential intestacy, legal costs, and family disputes — at the worst possible moment. The person most hurt by a badly drafted will is not the person who wrote it.

The Middle Ground: Online Will Writing

The reason people consider writing their own will is almost always cost. That reason has been removed. A legally binding will from a reputable online will writing service costs a fraction of a solicitor's fee, takes under an hour to complete, and includes every mandatory element — the revocation clause, executor and guardian appointments, residuary provisions, attestation clause, and step-by-step signing instructions.

Wills Assured produces a fully structured, compliant will for £19.99 — guided by a plain-English questionnaire that ensures nothing is missed. The output is a professionally formatted document that includes everything a DIY will would likely omit, at a price that eliminates the argument for attempting it alone.
