Do You Need a Solicitor to Write a Will? The Legal Truth — and Why So Many People Get It Wrong

Ask almost anyone whether they need a solicitor to write a will and the answer you'll get — from friends, colleagues, even well-meaning family members — is almost always yes. It's one of those facts that feels true. After all, a will is a legal document. Legal documents need lawyers. Lawyers cost money. Therefore writing a will is expensive, complicated, and requires professional help.

Every part of that chain of logic is wrong. And the persistence of this myth is, in large part, why over 31 million UK adults still don't have a valid will.

What the Law Actually Says

The legal requirements for a valid will in England and Wales have been largely unchanged since the Wills Act 1837. That Act — nearly 190 years old — sets out the rules simply and plainly:

• The person making the will (the testator) must be aged 18 or over.
• The testator must have testamentary capacity — meaning they must be of sound mind and understand what they are doing.
• The will must be in writing.
• It must be signed by the testator in the presence of two independent witnesses.
• Both witnesses must sign the will in the testator's presence.

That is the complete list. There is no requirement for a solicitor. No requirement for a notary, a legal stamp, or a court filing. A solicitor-free will is not a lesser will — it is every bit as legally binding as one that cost £400 to produce, provided the above conditions are met.

So Why Does Everyone Think They Need One?

The persistence of this myth isn't accidental. It has several roots, and understanding them helps to explain why such a straightforward legal reality remains so widely misunderstood.

1. The legal profession marketed itself well

For most of the twentieth century, solicitors had a near-monopoly on will writing services in the UK. There was no accessible alternative. If you wanted a proper will — not a handwritten scrap that might be contested — you went to a solicitor. That association between legal validity and professional involvement became deeply embedded in the public consciousness. A generation of parents told their children: "When the time comes, see a solicitor." The advice wasn't wrong then. It's just no longer the only option.

2. DIY wills have a bad reputation — for good reason

Part of the myth's staying power comes from genuine horror stories. Handwritten DIY wills — particularly those filled in using off-the-shelf kits — have an unfortunate track record of being invalid. A missing witness. An ambiguous bequest. A clause that contradicts another. These errors can lead to disputes, delays in probate, and ultimately a will being set aside entirely, leaving the estate to be distributed according to the rules of intestacy.

Those risks are real. But they're the risks of poorly drafted wills — not of wills produced without a solicitor. The problem was never the absence of a lawyer; it was the absence of proper legal structure and guidance. That distinction matters enormously.

3. Complexity got conflated with necessity

Wills can be complex. If your estate planning involves offshore assets, multiple business interests, discretionary trusts, or contested family dynamics, then the input of a specialist solicitor may well be appropriate. But those situations describe a small minority of estates. The vast majority of UK adults need a will that achieves a small number of straightforward things: appointing executors, naming beneficiaries, making provision for children, and perhaps recording specific wishes.

Complexity exists. It just doesn't apply to most people. Treating the exception as the rule has kept millions away from a process that, for them, is genuinely simple.

4. Nobody ever corrected the record

Until relatively recently, there was no commercial incentive to challenge the myth. Solicitors weren't going to advertise that their services were optional. High-street will writers — often unregulated — weren't known for public education campaigns. The financial press covered inheritance tax and complex trusts, not straightforward single wills for ordinary families. The myth filled a vacuum.

When You Might Genuinely Want Legal Advice

Honesty matters here. There are circumstances where instructing a specialist solicitor is genuinely the right decision:

• Contested or complex family dynamics — particularly where previous marriages, estranged relatives, or potential claims under the Inheritance (Provision for Family and Dependants) Act 1975 are in play.
• Significant business interests — where shares, partnerships, or succession planning require specialist structuring.
• Foreign assets or property abroad — which may require a separate will in the relevant jurisdiction.
• Complex tax planning — particularly where estates approach or exceed the inheritance tax threshold (currently £325,000, or up to £500,000 with the residence nil-rate band).
• Disputed testamentary capacity — where there is any risk that mental capacity may be challenged after death.

If your situation does fall into one of the categories above, the Law Society's Find a Solicitor tool is the best way to locate an accredited wills and probate specialist. For everything else — which is to say, for the vast majority of UK adults — a properly structured online will provides everything a solicitor would, without the cost, the appointments, or the wait.

What a Good Online Will Actually Delivers

There's an important difference between a DIY will and an online will writing service. The former asks you to fill in blank spaces on a generic template with no guidance. The latter — done properly — walks you through a structured questionnaire, applies legal logic to your answers, and produces a document that is compliant with UK law and ready to be signed and witnessed.

At Wills Assured, every will is generated to comply with the Wills Act 1837 and relevant UK case law. The output is a complete Last Will and Testament — properly numbered, correctly worded, and including all the standard provisions that solicitors include as a matter of course: appointment of executors and trustees, guardian provisions for minor children, specific gifts, residuary estate distribution, trust provisions for young beneficiaries, and a standard attestation clause.

A single will costs £19.99. A mirror will for couples — two complementary wills that reflect each other's wishes — costs £29.99. The process takes around 20 minutes. There are no appointments, no billable hours, and no hidden fees. For an independent cost comparison, MoneyHelper's will writing guide provides a useful overview of all your options.

The Signing and Witnessing Step

One element of the process does require your personal attention, and it's worth being clear about it: once your will is generated, you must sign it in front of two independent witnesses, who must also sign it in your presence. Your witnesses cannot be beneficiaries of the will or their spouses — if they are, their gift under the will becomes void (though the rest of the will remains valid).

This step cannot be done online, and it doesn't need to be. It requires two people — neighbours, colleagues, friends — and about five minutes. It is, in short, the opposite of complicated.

The Bottom Line

You do not need a solicitor to write a will in the UK. You never legally have. What you need is a will that is properly structured, correctly signed, and legally witnessed. Technology has made it easier than ever to achieve all three — affordably, quickly, and without setting foot in a law firm.

The myth that a solicitor is required has kept millions of families unprotected for decades. It's time to retire it.

Your family deserves the protection of a valid will. It costs less than a dinner out and takes less time than a commute.
