Can I Write My Own Will?

The truth about DIY wills - when they work and when they don't

Last updated: January 2025 | 8 min read

Yes, you can legally write your own will in the UK. There's no law requiring a solicitor. However, DIY wills are responsible for countless family disputes and failed inheritances every year. The money you save could cost your family far more in legal fees and heartache.

Professional wills from just £99. Is saving £99 worth risking your family's inheritance?

The Legal Requirements

A DIY will is legally valid if:

  • It's in writing (typed or handwritten)
  • You're 18 or over
  • You're of sound mind
  • You sign it in front of two witnesses
  • Both witnesses sign in your presence
  • Neither witness (nor their spouse) is a beneficiary

Sounds simple enough. So why do so many DIY wills fail?

Why DIY Wills Go Wrong

1. Ambiguous Language

Legal documents need precise wording. Phrases that seem clear to you can be interpreted multiple ways.

Example: "I leave my money to my children" - Does this include stepchildren? Adopted children? Grandchildren if a child has died? Money in bank accounts only, or all assets?

2. Witnessing Errors

The witnessing rules are strict. Common mistakes:

  • Signing in front of witnesses separately (must be together)
  • Witnesses signing before you do
  • Using a beneficiary as a witness (they lose their inheritance)
  • Not having witnesses sign

3. Missing Crucial Provisions

DIY wills often forget to include:

  • What happens if a beneficiary dies before you
  • Who inherits if your whole family dies
  • Guardian appointments for children
  • Executor powers and authorities
  • Trust provisions for young beneficiaries

4. Invalid Revocation

New wills should revoke old ones. If done incorrectly, you could have two partially valid wills causing chaos.

5. Not Accounting for All Assets

Forgetting assets or not understanding how they pass (joint property, pensions, life insurance) creates gaps in your estate plan.

Real DIY Will Disasters

Case 1: A man left "everything to my wife." When he died, his wife had already died. The will didn't name backup beneficiaries, so everything went to distant relatives under intestacy rules instead of his children.
Case 2: A woman's DIY will said "I leave my house to my son." She later sold the house and bought a flat. Her son got nothing because the specific property no longer existed, and she hadn't updated the will.
Case 3: A couple signed each other's wills by mistake. Both wills were invalid. The estate went through intestacy, costing thousands in legal fees.

When DIY Might Work

A DIY will may be acceptable if:

  • Your estate is very simple (no property, modest savings)
  • You're leaving everything to one person
  • You have no children
  • You're not married or in a civil partnership
  • You understand the witnessing requirements perfectly

But even then, a professional will costs from £99. Is it worth risking your family's inheritance to save that amount?

When You Definitely Need Professional Help

Get professional help if you have:

  • Property (house, flat, land)
  • Children (especially minor children)
  • A blended family
  • Business interests
  • Assets abroad
  • A complex family situation
  • Concerns about inheritance tax
  • Anyone you want to exclude
  • Beneficiaries with special needs

DIY Will Kits: Are They Better?

Will kits from stationers or online (£10-30) are better than a blank sheet of paper, but they still have problems:

  • One-size-fits-all approach
  • No advice on your specific situation
  • Easy to fill in incorrectly
  • No one checks your work
  • May not cover complex situations

Will kits account for a significant portion of contested wills.

The Cost of Getting It Wrong

Scenario Potential Cost
Professional simple will £99 - £200
Rectifying an invalid will £2,000 - £10,000+
Contesting a will in court £10,000 - £100,000+
Family relationships Priceless

Frequently Asked Questions

Is a handwritten will legal in the UK?

Yes, handwritten wills are legal if properly witnessed. However, they're more likely to contain errors and ambiguities.

Do I need a solicitor to make a will legal?

No, there's no legal requirement to use a solicitor. But professional help significantly reduces the risk of problems.

Can I use a will template from the internet?

You can, but templates don't adapt to your specific circumstances. Many are American and don't reflect UK law.

What if I just want to leave everything to one person?

Even simple wills benefit from professional drafting. What if that person dies before you? What if they're going through a divorce when you die?
