What Is the Best Way to Create a Will in the UK?
When deciding how to make a will, you have three main choices: crafting your own will (DIY), instructing a solicitor, or using a trusted online will-writing platform. Each method has distinct costs, legal risks, and levels of convenience. Here’s a comparison:
| Method | Cost Range | Risk of Invalidity | Best For | Ease of Updating |
|---|---|---|---|---|
| DIY (Homemade) | Free – £50 | High (errors, invalid witnessing) | Simple estates, low-value assets | Low (a new will or codicil needed every time) |
| Solicitor | £200 – £600+ | Low (professional legal review) | Complex estates, business owners, family disputes | Moderate (potential extra fees) |
| Online Platform | £50 – £150 | Medium–Low (legal checks, guided) | Most individuals, families and digital assets | High (simple updates, automated alerts) |

What Makes a Will Legally Valid in the UK? (Checklist)
For your will to be legally valid in England & Wales, the following must apply (based on the Wills Act 1837 and Mental Capacity Act 2005):
- Over 18 years old: The will-maker (testator) must be over 18 (reducing to 16 from 2025).
- Testamentary capacity: You must have ‘sound mind’—this means understanding the effect of your will and the extent of your estate.
- Knowledge and approval: You must know and approve your will’s contents.
- No undue influence: Your decisions must be free and voluntary, not pressured by others.
- In writing: The will must be on paper or, from 2025, in an accepted digital format.
- Signed by the testator: You must sign the will yourself.
- Witnessed by two independent adults: Both must be present, not beneficiaries or married to them, and must also sign in your presence.
- Revoking previous wills: Your new will should include a clause that cancels all former wills.
How to Create a Will: Step-by-Step Legal Process in 2025
The practical process for making a will is evolving. Here’s your step-by-step guide, reflecting both current rules and reforms under the Wills Bill 2025:
| Step | Up to 2024 | From 2025: Wills Bill Changes |
|---|---|---|
| Minimum Age | 18 | 16 |
| Format | Paper, signed in ink | Paper or electronic |
| Signing | Must be physically signed | Can be signed electronically |
| Witnessing | Two in-person adult witnesses | In-person or remotely via approved video platform |
| Revocation by Marriage | Marriage/civil partnership cancels prior will | Marriage does not revoke a valid will |
| Capacity Standard | “Sound mind” (common law) | Explicitly governed by the Mental Capacity Act 2005 |
How to make your will legally valid—Step-by-step:
Current Process (Up to 2024)
- List all your assets, desired beneficiaries, appointed executors, and guardians for children.
- Draft your will in clear, simple language.
- Sign the will in front of two independent adult witnesses.
- Ask your witnesses to sign in your presence and in each other’s presence.
- Store your will securely—avoid fasteners like staples that could cause suspicion of tampering.
- Update your will if circumstances in your life change.
From 2025 (Wills Bill Reforms)
- You can prepare your will on paper or in an approved electronic format.
- You may sign either physically or electronically.
- Witnessing can occur in-person or remotely by secure video, but both witnesses must see your signature in real time.
- The minimum age to make a will will be 16.
- Marriage or civil partnerships will no longer revoke a will automatically.
- Best practice remains: update after key life events and ensure proper witnessing.
Will Signing Requirements UK: Who Can Witness, and What Are the Rules?
Mistakes in signing and witnessing are the most common reason wills are challenged or ruled invalid. Take care at this critical step.
Step-by-Step Signing Instructions
- Prepare your final will and arrange for two independent adults to act as witnesses.
- Sign the document at the indicated place, with both witnesses physically or digitally present (according to current law).
- Each witness then signs, in your presence and in each other’s presence.
- Ensure all signatures are clear, dated, and in ink (unless signing electronically under the 2025 reforms).
Who Can Witness a Will?
| Requirement | Legal Rule | Why This Matters |
|---|---|---|
| Age | At least 18 now (16 from 2025) | Under-age witnesses are not legally valid |
| Independence | Must not be a beneficiary or their partner/spouse | Protects against conflicts of interest and void gifts |
| Simultaneous | All must be present at the same time during signing | Ensures authenticity, prevents disputes |
| Location | In-person, until allowed video witnessing (2025+) | Virtual or remote only after legal reforms |
Key Clauses and Appointments to Include in Your Will
A legally robust will covers much more than just naming who gets what. Include all vital appointments and clauses to avoid disputes and close loopholes.
| Clause/Appointment | What It Does | Why It’s Essential |
|---|---|---|
| Executors | Appoint who manages and distributes your estate | Avoids court-appointed administrators, reduces delay |
| Guardians | Choose who cares for your children under 18 | Prevents strangers or the courts making the decision |
| Beneficiaries | Clearly specify who inherits each asset | Minimises confusion, family feuds, court cases |
| Specific Gifts | Allocate special personal items or cash to certain people | Ensures jewellery, heirlooms, etc, go to the right person |
| Residue Clause | Directs how remaining assets are divided | Avoids part of your estate being treated as intestate |
| Digital Assets Clause | Covers access to online accounts, websites, crypto, etc | Prevents crucial business or family data being lost |
| Revocation Clause | Cancels any prior wills and codicils | Ensures only your most recent wishes are followed |
Homemade, Online, or Solicitor? Comparing the Best Ways to Create a Will in the UK
Choosing the right approach comes down to the value and complexity of your estate, your personal circumstances, and your appetite for risk.
- DIY (Homemade) Will: Only appropriate for the simplest estates—no children, no business, no complexities. High risk of legal errors or missing clauses. Very low upfront cost but potentially costly to fix.
- Online Will Platform (e.g., Go-Legal AI): Guided questions, automated checks, digital asset options, and secure storage make this best for most people—especially modern families and business owners. Costs are modest and updates are easy.
- Solicitor-Drafted Will: Recommended only for high-value, complex estates or potentially contentious situations. Ensures every legal nuance is addressed, but fees are higher and updates may take longer.
Risks and Common Mistakes When Making Your Will
Major risks businesses and individuals face when preparing a will include:
- Invalid witnessing: Missing signatures or using a beneficiary as a witness voids gifts.
- Ambiguous clauses: Unclear instructions can spark family fights or legal challenges.
- Omitting digital assets: Online business accounts, cloud storage, digital funds are lost.
- Failing to revoke previous wills: Multiple conflicting wills—leading to probate confusion.
- Out-of-date wills: Major life events not reflected, unintentionally disinheriting loved ones.
- Undue influence: Signs of pressure or lack of clear mental capacity invite legal challenges.
- Lack of understanding: Using legal jargon you don’t understand, and can’t explain if questioned.
How to Store and Update Your Will Securely
Safe, accessible storage ensures your will is found and followed when it matters most.
Storage options:
- Home Safe/Fireproof Box
- Pros: Immediate access; Cons: At risk from theft or damage
- Legal Professional Storage
- Pros: Secure handling and periodic reminders; Cons: Ongoing fee possible, slower retrieval
- Probate Registry (HMCTS)
- Pros: Official, secure, government-managed (£20 per will in 2024); Cons: Slightly slower access
- Digital Vault (Go-Legal AI)
- Pros: Bank-level encryption, instant updating and reminders; Cons: Must grant executors clear access, subscription applies
When should you update your will?
- After getting married/civil partnership (your will is still valid from 2025)
- After divorce or separation
- Birth or adoption of a child
- Major financial or property changes
- Death of a beneficiary or executor
A codicil allows simple amendments to an existing will—like changing guardians or small bequests—without writing a full new will. However, it must be signed and witnessed again according to these rules.
Digital Assets, Major Life Changes & Modern Will-Making Essentials
Including digital assets in your will has become essential as business and personal life move online. Missing digital accounts or failing to appoint a digital executor can cause irretrievable losses.
How to Include Digital Assets
- Inventory: List digital assets—banking, crypto-wallets, subscriptions, business sites.
- Instructions: Assign who should receive or manage each digital asset—often your executor or a separate digital executor.
- Access: Never include passwords in your will (wills become public files after probate). Instead, provide secure access instructions separately.
- Digital Asset Clause: Make it explicit in your will that the executor has legal right to manage digital property.
What Is Changing? New Rules for Wills in the UK (Wills Bill 2025 & Electronic Witnessing)
From 2025, significant modernisation comes into force. The Wills Bill 2025 makes will-writing accessible for young adults, tech users, and remote signers. Here’s what’s changing:
| Aspect | Before 2025 | From 2025 |
|---|---|---|
| Minimum Age | 18 | 16 |
| Will Format | Paper with wet signature | Digital or paper, e-signatures permitted |
| Witnessing | Both witnesses must be in the room | Remote witnessing (video) legally valid |
| Revocation by Marriage | Marriage cancels your old will | Marriage does not revoke a valid will |
| Mental Capacity Standard | “Sound mind” (court-developed) | Clear definition via Mental Capacity Act 2005 |
Transition Risks:
Not all DIY kits, solicitor templates or will-writing platforms will be up to date. Using outdated forms or systems could invalidate your will—especially relating to remote witnessing or e-signatures after 2025.

Frequently Asked Questions
Can I write my own will and is it legally valid in the UK?
Yes. Anyone over 18 (16 from 2025) can make a will provided it is written, signed and properly witnessed. Homemade wills can be valid, but mistakes are common and can cause future disputes.
Who cannot witness a will in the UK?
Anyone set to benefit from your will, or their spouse/civil partner, cannot be a witness—otherwise they lose their inheritance. Witnesses must be over the legal minimum age and possess sound mind.
How much does it cost to make a will in the UK?
DIY: Free to £50. Online: £50–£150. Solicitor: £200 and up, depending on complexity and advice needed.
Is an online will legally binding in England & Wales?
Yes—if it’s properly written, signed, and witnessed according to UK law. Our solutions ensure every legal step is fully met (including remote options from 2025).
Does marriage cancel my previous will?
Currently, yes—unless your old will was made specifically ‘in contemplation’ of marriage. From 2025, marriage will not automatically revoke a valid will.
What happens if my will isn’t witnessed correctly?
The will may be declared invalid or partially disregarded, with your estate following older wills or intestacy rules, not your wishes.
How can I update my will if my life changes (e.g., divorce)?
Draft a new will or use a codicil—which must be signed and witnessed just like your main will. Always update after major life events.
Where should I keep my original will?
Best options: Home safe, with a solicitor, Probate Registry, or a secure digital vault. Always inform your executors where to find your will.
What is a codicil?
A codicil is a short, formal document used to amend your existing will. It must be signed and witnessed by two independent adult witnesses.
How often should I review my will?
Review after every major life event: marriage, divorce, birth, death, buying a business, or major asset changes. Annual reminders are good practice.
Can I leave digital assets in my will?
Yes. Specify in your will who receives your digital assets (like crypto, cloud files, websites), and use a separate, secure record for usernames and passwords.
