Online Will Services: What They're Good For, and Where a Solicitor Still Matters
Online will-writing services are cheaper and faster than a solicitor, but the Law Commission has flagged real concerns about validity and vulnerability. When a DIY digital will is fine, and when it genuinely isn't.
The appeal of online will services
Writing a will through a solicitor can feel like a disproportionate cost and hassle for a straightforward situation β which is exactly the gap online will-writing services have grown to fill. They're significantly cheaper, faster, and can be completed from home. For the right situation, they produce a perfectly valid, legally sound document.
What actually makes a will legally valid
It's worth being clear that the mechanism used to produce the wording β online service, solicitor, or handwritten from scratch β isn't itself what determines legal validity. In England and Wales, a will is valid if it:
- Is in writing
- Is signed by the person making it (the testator)
- Is signed in the presence of two witnesses, who then also sign in the testator's presence
- Is made by someone with the mental capacity to understand what they're doing, and free from undue influence
Most online will services in the UK produce a document you then print and execute in the traditional way β physical wet-ink signature and physical witnesses present at the same time β rather than a fully electronic, digitally-signed will. Fully digital execution remains a more legally uncertain area, under long-running Law Commission review, rather than a standard, settled alternative to traditional execution.

Online will services are best suited to genuinely straightforward circumstances:
- A single person, or a married couple/civil partnership, with uncomplicated assets
- Clear, uncontested intended beneficiaries (typically a spouse and/or children with no complicating family dynamics)
- No significant business assets, overseas property, or trusts involved
- No obvious Inheritance Tax planning need given the size of the estate
- No family members likely to dispute the will or challenge the testator's capacity
When a solicitor is the safer choice
Certain situations carry a meaningfully higher risk if handled with a generic template rather than tailored legal advice:
| Situation | Why a solicitor matters more |
|---|---|
| Blended families, especially step-children involved | Step-children have no automatic intestacy rights β the wording needs to be precise and deliberate |
| Significant or complex assets | Business assets, overseas property, and multiple property ownership all raise issues a template may not anticipate |
| Inheritance Tax planning relevant | Trusts, gifting strategies and allowance planning generally require tailored advice, not a generic document |
| Concerns about mental capacity of a family member | A will made where capacity could later be challenged benefits from a solicitor's contemporaneous assessment and record-keeping |
| Risk of the will being contested | Professional drafting and advice can reduce (though never eliminate) the risk of a successful challenge |
The real risk: a will that creates more problems than it solves
It's tempting to think any will is better than no will at all, but this isn't always true. A DIY will with ambiguous wording, an internal inconsistency, or incorrect execution (for example, a witness who is also a beneficiary, which can invalidate that specific gift) can create exactly the kind of dispute and uncertainty a will is meant to avoid β sometimes requiring expensive court proceedings simply to interpret what was actually meant, or resulting in a challenge to the will's validity altogether. By contrast, dying intestate at least produces a clear, predictable (if not personally tailored) legal outcome under the intestacy rules.

Most entry-level online will services focus purely on producing a valid legal document reflecting straightforward wishes β they generally don't provide Inheritance Tax advice, flag available exemptions and reliefs, or structure trusts to manage a significant estate's tax position. If your estate is large enough that Inheritance Tax is a realistic concern, or you want to explore trust structures (for a blended family, a vulnerable beneficiary, or general tax efficiency), that's a strong signal to move beyond a basic online template and get professional advice.
Practical steps
- Honestly assess your situation's complexity β genuinely simple, or one of the higher-risk categories above?
- If using an online service, follow the execution instructions precisely β correct witnessing is not optional, and getting it wrong can invalidate the whole will or specific gifts within it.
- Never let a beneficiary (or their spouse) act as a witness β this can invalidate that person's gift under the will.
- Store the signed will securely and make sure your executor knows where to find it.
- Review your will after major life events β marriage, divorce, having children, or a significant change in assets β regardless of whether it was drafted online or by a solicitor, since an out-of-date will can be almost as problematic as no will at all.
Frequently asked questions
Are online wills legally valid in the UK?
A will produced through an online service can be legally valid, provided it meets the same formal legal requirements as any will β it must be in writing, signed by the person making it (the testator) in the presence of two witnesses, who must also sign in the testator's presence. The online service producing the document doesn't itself make the will valid or invalid; proper execution (signing and witnessing) is what matters legally.
What's the difference between an online will service and an actual electronic (digital-signature) will?
Most 'online will services' in the UK actually produce a document you print out and sign physically with wet-ink witnesses, using online tools purely to gather information and generate the wording β this is different from a fully electronic will signed and witnessed digitally, which remains a more legally uncertain area in England and Wales, discussed by the Law Commission but not yet a standard, confirmed practice in the same way as traditional wet-ink execution.
When is an online will service likely to be fine?
For genuinely simple situations β a single person or couple with straightforward assets, clear intended beneficiaries, no complex family structure (no step-children, no estranged relatives, no significant business or overseas assets), and no significant Inheritance Tax planning need β a well-reviewed online service can often produce a valid, suitable will at a fraction of the cost of a solicitor.
When should I use a solicitor instead of an online service?
A solicitor is generally the safer choice for blended families (particularly involving step-children, who have no automatic intestacy rights), significant or complex assets, business ownership, overseas property, anyone with mental capacity concerns about a family member who might contest the will, or where Inheritance Tax planning (trusts, gifting strategies) is relevant β these situations carry a materially higher risk of a poorly drafted DIY will causing serious problems.
Has the Law Commission raised concerns about online wills specifically?
The Law Commission's long-running review of wills law has considered a range of concerns relevant to informal and online will-making, including the risk of wills being made without adequate safeguards against undue influence or lack of capacity, and the general modernisation of wills law β check current Law Commission and government publications for the latest position, as this remains an active area of policy review rather than settled, finalised reform.
Can a poorly worded DIY will actually cause more problems than not having a will at all?
Yes, this is a genuine risk β an ambiguously worded, incorrectly executed, or internally inconsistent DIY will can create exactly the kind of uncertainty and family dispute that a will is meant to prevent, sometimes leading to expensive court proceedings to interpret or challenge it, whereas the intestacy rules (while not reflecting personal wishes) at least provide a clear, predictable, and settled distribution outcome.
Do online will services check for Inheritance Tax issues?
Most basic online will services focus on the legal document itself rather than providing tax advice, so they generally won't flag Inheritance Tax planning opportunities (such as trust structures, or use of exemptions) the way a solicitor or specialist estate planner might β if your estate is large enough that Inheritance Tax is a live concern, this is a strong signal to seek professional advice rather than relying solely on an online template.
How much does an online will typically cost compared to a solicitor?
Online will services are typically very significantly cheaper than instructing a solicitor directly for a straightforward will, which is their main appeal β but the cost saving needs to be weighed against the complexity of your specific situation and the potential cost of getting it wrong, which can vastly exceed any amount saved upfront.
