Can I Write a Will on My Own in the UK—Or Is It Too Risky?

Writing your own will can seem appealing if you want to save costs or avoid time-consuming solicitor appointments. In England and Wales, you are legally allowed to write a will yourself—whether that’s using a template, an online document builder, or handwriting the will from scratch.

Many people want to know if making a will without a solicitor is enough. This guide explains how to do it properly and spot the pitfalls. Our aim at Go-Legal AI is to give you the confidence to protect your legacy, your family, and your business without unnecessary legal risk. Smart, compliant will-making is now affordable, secure, and remarkably easy.

Is Writing Your Own Will Legal and Safe in England and Wales?

You are legally permitted to write your own will in England and Wales—these “DIY” or “homemade” wills are accepted under current law if every legal requirement is strictly met. This means your will can be homemade, created with a template, or digital. No solicitor is required by law.

However, legality doesn’t mean safety. A homemade will is a legally risky route if you are not clear on formalities or your wishes are remotely complex.

The Real Risks of DIY Wills

Most people who write their own will are unaware that a single flaw—such as using a beneficiary as a witness or failing to appoint executors—could see their wishes disregarded. This is particularly risky for business owners, blended families, people with overseas or digital assets, and anyone whose affairs are not straightforward.

What Legal Requirements Must a Will Meet in the UK?

Strict legal standards must be followed for a will to be valid in England and Wales. Failing any one requirement can invalidate the entire document.

Who Can Make a Will?

To make a valid will, you must:

• Be 18 or over.
• Have mental capacity (this means understanding the effects of making a will and the extent of your assets).
• Make the will voluntarily, without undue pressure.

The person making the will is called the testator.

Will Signing and Witnessing Rules

The Wills Act 1837 sets out the core rules:

• The will must be signed by the testator in the presence of two independent adult witnesses at the same time.
• Each witness must then sign the will in your presence.
• Witnesses must not be beneficiaries, nor married to, or civil partners of, beneficiaries.
• Witnesses must be over 18 and ideally unrelated for extra protection.

If a beneficiary acts as a witness, any gift to them under the will is invalid.

What Must a Valid Will Include?

• Be in writing—typed, printed, or handwritten.
• Clearly state that it revokes previous wills.
• Name at least one executor (person who carries out your wishes).
• State clearly how your assets are to be divided.
• Be signed and dated by you in front of both witnesses, who must also sign in your presence.

Homemade and DIY Wills: What Are the Common Pitfalls?

Homemade wills are appealing for their low cost but are regularly found invalid, especially in complex family or business situations.

What Can Make Your DIY Will Invalid?

Common reasons homemade wills are overturned include:

• Only one witness instead of two.
• An executor or primary beneficiary witnessing the will.
• Signing the will outside of the presence of both witnesses.
• Mistakenly making handwritten changes (codicils) after signing, without proper new witnesses.
• Vague wording such as “my savings” (without specifying the account or amount).
• Failing to revoke all earlier wills.
• Leaving out important assets, like shares in a limited company or online business accounts.

Essential Clauses Every Will Should Contain

Step-by-Step: How to Write Your Own Will in the UK

Prepare Thoroughly Before Writing

• Make a full list of all your property: savings, investments, property, vehicles, business shares, digital assets, and valuables.
• Collect names, addresses, and contact details of beneficiaries and executors.
• List any debts or liabilities.
• Decide who’s best placed to be guardian to any children under 18.
• Remember digital assets (e.g., cloud accounts, domain names, social media).

Draft and Format Clearly

• Write in clear, unambiguous language; avoid terms that can be interpreted differently.
• Structure the will logically: title, revocation, personal information, list of bequests, residuary clause, executor appointment, date and signatures.
• Number each paragraph and section for reference and clarity.
• Avoid large spaces or blank pages—these can be exploited in fraud or cause disputes.

Secure Correct Witnessing

1. Select two independent witnesses—adults, not named in the will, preferably unrelated.
2. Gather all in one room.
3. You sign the will at the end (using your usual signature) in front of them.
4. Each witness signs directly underneath you, with their full details (name, address, occupation).
5. Never ask a beneficiary, or their married partner, to act as a witness.

Store Your Will Safely

• Keep the original signed will in a fireproof, waterproof place: e.g., a safe deposit, secure home safe, or with a trusted digital will provider.
• Tell your chosen executors where and how to access the document.
• Keep a digital scan, but remember—it is the signed original, not a copy, that matters legally.
• Destroy all previous versions when you write a new will.

What Happens If a DIY Will Is Invalid or Contested?

What Is Intestacy, and Why Does It Matter?

If your will is ruled invalid, or not found, your estate is shared under intestacy rules. The law then applies a fixed order of inheritance: typically spouse/civil partner, children, parents, and siblings. Unmarried partners, step-children, and close friends get nothing unless you name them in a valid will.

Consequences of a Contested or Invalid Will

• Probate courts can freeze estates for many months, delaying support for dependents or business continuity.
• Legal costs are paid from your estate, reducing inheritances for your loved ones.
• Disputes over homemade wills are common where there are ambiguities, poorly defined gifts, or unqualified witnesses.

Frequently Asked Questions

Is it legal to write your own will in the UK?

Yes, anyone in England and Wales who is 18 or older and of sound mind can legally write a will, as long as all witnessing and signing rules are correctly followed.

Who can witness my will to make it legally binding?

Any two independent adults (over 18) who are not beneficiaries or married to a beneficiary. Ideally, pick people outside your family to avoid disputes.

What if I make a mistake in my DIY will?

If you get the witnessing wrong, or the will is unclear or unsigned, your will may be partly or wholly invalid. This often leads to disputes, delays, or your estate being distributed according to intestacy rules.

Can a handwritten will be valid in the UK?

Yes. Handwritten (“holograph”) wills are legal if they meet all the same witnessing and signing requirements.

How do I change or update a homemade will?

Write a new will or use a properly witnessed codicil. Always destroy all previous versions to avoid confusion.

What assets should I include in my will?

List everything: current and savings accounts, property, vehicles, shares, business interests, digital accounts, and valuable personal items.

Should business owners use a solicitor—or is a template enough?

If you own a business, have intellectual property, or complex family circumstances, use a solicitor or our solicitor-reviewed AI solution. Standard templates rarely cover business-specific risks.

Is an online will accepted in probate court?

Yes, provided you print, sign, and witness it according to law. The legal validity depends on the process, not the origin.

What’s a “letter of wishes” versus a will?

A will is binding in law; a letter of wishes gives extra, non-binding guidance to your executors or family.

What’s intestacy and how will it affect my family?

Intestacy is when someone dies without a valid will. The law, not you, decides who inherits—excluding cohabiting partners or stepchildren unless named in a valid will.

Write Your Legally Valid Will with Confidence

Understanding DIY will basics and legal requirements is empowering, but a single small mistake could put your entire legacy at risk. From strict witnessing rules and ambiguous gift wording to missing out business or digital assets, homemade wills can easily be challenged or disregarded. Probate delays, unexpected court battles, and disappointed beneficiaries are too common where DIY wills are used without expert review.
