Frequently Asked Questions

Do I legally need a solicitor to write a will?

No — in England and Wales you can write your own will (holographic will) or use a non-solicitor will writer. However, for anything beyond a very simple estate, a solicitor or regulated will writer is strongly recommended to avoid costly errors.

What makes a will legally valid in the UK?

A valid will must: be in writing, be signed by the testator (will maker) in the presence of 2 independent witnesses, and be signed by both witnesses. The testator must be 18+ and of sound mind. Witnesses cannot benefit from the will.

What is the Free Wills Month?

Free Wills Month is a national initiative where major charities (Age UK, Cancer Research UK, BHF etc.) partner with solicitors to offer free basic wills to people aged 55+. Usually runs in October/November and March/May.

What does a basic will include?

A basic will typically covers: executor appointment, guardians for children (if applicable), specific legacies (gifts of particular items/amounts), and the residuary estate (everything else). Simple trusts may be included.

When do I need a more complex will?

Consider a complex will if: you own a business, have assets in multiple countries, have a blended family or children from previous relationships, want to set up trusts for vulnerable beneficiaries, or have a large estate with IHT planning needs.

What is a mirror will?

Mirror wills are two virtually identical wills made by a couple — typically leaving everything to each other, then to children. They're created simultaneously. Note: neither will is legally bound by the other — either party could change their will independently later.

Can I update my will myself?

No — you cannot simply cross out or amend a will. Changes must be made via a formal 'codicil' (minor amendments) or by writing a completely new will. Any handwritten changes to a signed will can invalidate sections or the whole document.

What happens if I die without a will (intestate)?

The intestacy rules determine who inherits. For a married person: spouse inherits the first £322,000 plus half of the remainder; children share the other half equally. Unmarried partners get nothing under the rules — making a will essential if you're not married.
