Why You Need a Will in the UK

Nearly 60% of UK adults don’t have a will. Many assume their spouse or partner will automatically inherit everything — but under intestacy law, this isn’t always true. Without a valid will:

  • Unmarried partners: receive nothing under intestacy rules, regardless of how long you’ve lived together
  • Children: may not receive what you intended, or may receive it at age 18 rather than when you’d prefer
  • Your home: may need to be sold to divide assets between relatives you didn’t intend to benefit
  • Stepchildren: have no automatic inheritance rights unless specifically named in a will
  • Your wishes: about funeral arrangements, guardianship of children, and charitable gifts won’t be legally recorded

A properly drafted will puts you in control. It’s not about wealth — it’s about making sure the right people are protected. Ready for a document that works in real life?

How to Write a Legally Valid Will in the UK

Writing a will doesn’t require a solicitor — but it does require following specific legal rules. A DIY will is perfectly valid if it meets the requirements under the Wills Act 1837. The basic steps:
  1. Gather your information: List all assets, debts, and who you want to benefit
  2. Choose your executors: Appoint trusted people to carry out your wishes
  3. Name your beneficiaries: Decide who gets what
  4. Appoint guardians: If you have children under 18
  5. Draft the will: Use clear, unambiguous language
  6. Sign correctly: In front of two independent witnesses
  7. Store safely: Keep the original somewhere secure

What Makes a Will Legally Valid in the UK?

For a will to be legally valid in England and Wales, it must meet these requirements:
  • Written: The will must be in writing (typed or handwritten)
  • Signed: The testator (person making the will) must sign it, or direct someone to sign on their behalf
  • Witnessed: Two independent witnesses must watch the testator sign, then sign themselves
  • Capacity: The testator must be 18 or over and of sound mind
  • Intention: The testator must intend the document to be their will
Common mistakes that invalidate wills:
  • Witness is a beneficiary: Anyone who inherits under the will cannot be a witness
  • Witness’s spouse is a beneficiary: Same rule applies to witnesses’ spouses
  • Not signed properly: All signatures must be made in each other’s presence
  • Alterations after signing: Changes made after witnessing are invalid unless re-witnessed

What Happens If You Die Without a Will?

If you die without a valid will (called “dying intestate”), your estate is distributed according to intestacy rules — not your wishes. Under intestacy rules:
  • Married/civil partner: Gets the first £322,000 plus half of the remainder. The rest goes to children.
  • Unmarried partner: Gets nothing — regardless of how long you lived together
  • No spouse or children: Estate passes to parents, then siblings, then more distant relatives
  • No living relatives: Everything goes to the Crown
The real impact:
  • Your unmarried partner may need to leave your shared home
  • Your children receive everything at 18, not when they’re ready
  • Stepchildren receive nothing unless you’ve legally adopted them
  • Family disputes become more likely without clear instructions

Frequently Asked Questions About Wills in the UK

Can I write my own will legally in the UK?

Yes — there’s no legal requirement to use a solicitor. A DIY will is perfectly valid if it’s written correctly, signed by you, and witnessed by two independent adults who aren’t beneficiaries. Many people successfully write their own wills using professionally drafted templates.

Do I need a solicitor to write a will in the UK?

No — solicitors are only necessary for complex estates involving business assets, foreign property, trusts, or potential inheritance tax planning. For straightforward estates, a professionally drafted template provides the same legal protection at a fraction of the cost — typically £10 versus £150-£500 for solicitor fees.

What makes a will legally valid in the UK?

Under the Wills Act 1837, a valid will must be: written (typed or handwritten), signed by the testator (or someone directed by them), witnessed by two independent adults who aren’t beneficiaries, and made by someone aged 18+ with mental capacity. All signatures must be made in each other’s presence.

How much does a will cost without a solicitor in the UK?

DIY will templates typically cost £10-£30 for a professionally drafted document. Will-writing services charge £100-£300. Solicitors charge £150-£500 for a simple will, or £500-£1,000+ for mirror wills or complex estates. A template provides the same legal validity at the lowest cost.

What is the biggest mistake people make with wills?

Having a beneficiary or their spouse act as a witness — this is the most common error that partially or fully invalidates a will. If a witness (or their spouse) is named as a beneficiary, that gift fails — the rest of the will remains valid, but they receive nothing. Always use independent witnesses with no interest in the estate.

What happens if I die without a will in the UK?

Your estate is distributed according to intestacy rules, not your wishes. Your spouse receives the first £322,000 plus half of the remainder — children get the rest. Unmarried partners receive nothing. Stepchildren receive nothing. If you have no close relatives, everything goes to the Crown. A simple will prevents all of this.

The Truth About "Free" Legal Template Sites (What You're Really Signing Up For)

Most websites offering a "free legal template" follow the same pattern:

  • You click because it's advertised as free
  • You spend 10–15 minutes answering questions
  • At the very end, you must create an account or start a "free trial"
  • Your card is required upfront
  • The subscription auto-renews at £29–£39 per month

This isn't a free template – it's a subscription service. Many people only realise after being charged £300–£400 over the year.

Why These "Free" Templates Are a Legal Risk

  • Outdated wording: not aligned with current UK law
  • Missing mandatory clauses: required for legal validity
  • No compliance guidance: leaving users without legal context
  • No structured checklist: no way to verify the document works
  • Not kept updated: often unchanged when legislation changes

One incorrect clause can weaken or invalidate the entire document.

Hidden Problem: Many "Free Template" Sites Aren't Even UK-Based

Another major issue is that many free or auto-subscription template sites operate outside the UK and use documents originally drafted for the US legal system. These are then loosely adapted for "international use," which creates serious problems:

  • Incorrect terminology: taken from US contract law
  • Missing UK statutory references: essential legal requirements omitted
  • Non-applicable clauses: terms that don't apply under UK legislation
  • Legal conflicts: risks breaching UK consumer, employment, or GDPR rules

Why Templates UK Does the Opposite

  • Drafted by UK professionals: written by experienced business & legal experts
  • UK-law only: no US crossover or generic "international" templates
  • One-time price from £10.00: no subscriptions, no renewals
  • Full preview: see the exact document before buying
