Writing a Will in England and Wales

Written by the AWAY Wills Team | Last updated February 2026

A Will is a legal document that sets out what happens to your estate when you die. Your estate includes your money, property, possessions, and any other assets you own. In England and Wales, you must be 18+, write it down and sign it with two witnesses present. A Will lets you decide who inherits, appoint Executors, name a Guardian for children under 18, and avoid the fixed rules of intestacy that apply if you die without one.

In England and Wales, a Will only takes effect after death. While you are alive, it has no legal impact and can be changed at any time.

What does a Will let me do?

A valid Will allows you to:

  • Decide who inherits your estate

  • Appoint Executors to carry out your wishes

  • Name a Guardian for any children under 18

  • Record funeral preferences

  • Reduce delays and uncertainty for the people you leave behind

Without a Will, these decisions are made according to the rules of intestacy - fixed legal rules that often do not reflect modern family life.

Who needs a Will?

A Will is not just for the wealthy or the elderly. You should consider writing one if you:

  • Have children or dependants

  • Are in a long-term relationship but not married or in a civil partnership

  • Own or share property

  • Have step-children or chosen family you want to provide for

  • Want clarity over who is responsible for your affairs

If any of those apply to you, a Will matters.

What happens if I die without a Will?

Dying without a valid Will in England and Wales means your estate is dealt with under the rules of intestacy. These are fixed rules that apply the same framework to everyone, regardless of your actual circumstances.

They do not account for unmarried partners, blended families, or personal wishes. In many cases, the people closest to you have no automatic legal right to anything.

A Will is the only way to replace those default rules with your own decisions.

With a Will vs Without a Will: What's the Difference in England and Wales

What are the legal requirements to make a Will?

To be valid in England and Wales, a Will must:

  • Be made by someone aged 18 or over

  • Be made voluntarily and with mental capacity

  • Be in writing

  • Be signed by the person making it

  • Be witnessed by two independent witnesses, present at the same time

If any of these requirements are not met, the Will may be invalid.

How does the process of writing a Will work?

Writing a Will does not have to be complicated, but it does need to be done correctly.

At a high level, you will need to:

  1. Decide what you want to happen to your estate

  2. Choose who should inherit

  3. Appoint one or more Executors

  4. Name a Guardian if you have children under 18

  5. Sign and witness the document correctly

Some people write their own Will. Others prefer professional support. What matters most is that the final document is clear, legally valid, and reflects your actual wishes.

When should I update my Will?

A Will should be reviewed whenever your circumstances change. Common reasons to update include:

  • Having children

  • Buying or selling property

  • Getting married, separated, or divorced

  • Changes in who you want to inherit

  • Changes in your choice of Guardian or Executor

Reviewing every three to five years is a sensible habit and one that we will remind you of, if you’re a client of ours.

Guardianship

If you have children under 18, your Will is the only place in England and Wales where you can formally record who you want to care for them if both parents die.
