What Makes a Will Legal in England and Wales?
For a will to be valid in England and Wales, it must meet four requirements:
- You must be 18 or over (exceptions apply for members of the armed forces)
- You must have testamentary capacity — be of sound mind and understand what you are doing
- The will must be in writing — typed or handwritten
- You must sign it in front of two witnesses, who must both sign in your presence — witnesses cannot be beneficiaries or their spouses
⚠ Important: Even a small error — such as a witness being a beneficiary, or missing a signature — can invalidate a will entirely. Courts rule on this regularly.
What Should a Will Include?
- Executor(s) — who will administer your estate after you die
- Beneficiaries — who inherits your assets and in what proportions
- Specific gifts — items or amounts to specific people or charities
- Residuary estate — what happens to everything not specifically gifted
- Guardian — who should care for your children if both parents die
- Funeral wishes — optional but useful for your family
Can I Write My Own Will?
Yes, a DIY will is legally valid if it meets the requirements above. However, homemade wills are among the most common sources of estate disputes and challenges in English law. Common problems include:
- Ambiguous wording that creates uncertainty about intent
- Failing to account for all assets
- Not updating after divorce (marriage revokes a will; divorce does not)
- Witnessing errors
- Not considering inheritance tax implications
For most people, a professionally drafted will from £69 is far cheaper insurance than litigation after death.
How Much Does It Cost to Write a Will?

How to Update a Will
Never make handwritten amendments to a signed will — this can invalidate the whole document. To change a will you have two options:
- Codicil — a separate document making a specific amendment, signed and witnessed in the same way as the original will
- New will — the simplest option for significant changes; a new will should explicitly revoke all previous wills
You should review your will after any major life event: marriage, divorce, birth of children or grandchildren, significant change in assets, or death of a beneficiary.
