1. Short answer – what makes a will legally valid in Scotland?

In Scotland, a will is usually legally valid if:

  • It is in writing (a physical printed document, not just on a screen).
  • It clearly sets out your wishes in a way that can be understood.
  • You sign it at the end.
  • You sign the last page in front of one independent witness who also signs.
  • You have mental capacity and are not being pressured or forced.

Most “will problems” in Scotland are not about clever legal arguments — they are about simple issues like
poor signing, missing witness details, or unclear wording.

2. The legal validity checklist (Scotland)

Use this checklist to sanity-check whether a will is likely to be treated as valid in Scotland.

2.1 You have capacity and you are acting voluntarily

You must understand what a will is and what it does, and you must not be signing under pressure.
If your circumstances are sensitive (for example, family conflict), it can be worth adding extra safeguards.

2.2 The will is in writing

A will must be written down. Typed and printed is fine. The key point is that the signed original exists as
a physical document.

2.3 Your wishes are clear and practical

A good will is not just “legal” — it is easy for your family to follow. Clarity matters. Make it obvious:

  • Who your executors are.
  • Who inherits (and what happens if they die before you).
  • Any specific gifts (money or items) that matter to you.
  • What happens to the “rest” of your estate (the residuary estate).

2.4 You sign the will at the end

Your signature should appear where the will indicates for the testator (the person making the will).
Signing in the wrong place, or leaving the final page unsigned, is a common and avoidable mistake.

2.5 One witness is present when you sign the final page

In Scotland, the usual rule is one witness. They must be present when you sign the final page,
and they must then sign as witness.

2.6 The witness details are complete

Your witness should sign and add their details as indicated (typically name and address).
This helps avoid arguments later about who witnessed the signature.

3. Signing and witnessing (the most common failure point)

The wording of a will can be perfectly sensible, but if the signing is sloppy it can create real problems.
For most people, the safest approach is:

  1. Print the full will, including all pages.
  2. Sign or initial every page (if your will pack instructs you to do so).
  3. On the final page, sign your full name where indicated.
  4. Have your witness present in the same room when you sign the final page.
  5. The witness then signs and adds their details where shown.

4. Common mistakes that can cause problems later

These are the most common issues we see with DIY and template-based wills:

  • Not signing the final page correctly (or forgetting to sign at all).
  • Witness not present when the will is signed.
  • Witness details missing or incomplete.
  • Using a template written for England & Wales rather than Scotland.
  • Unclear gifts (for example “split everything fairly” without detail).
  • No substitute beneficiaries (if your main beneficiary dies first).
  • Not updating the will after major life events (marriage, separation, new child, new property).
  • Storing the will somewhere nobody can find.

6. When you should speak to a Scottish solicitor

Many Scottish families have a straightforward estate and can put a sensible will in place without a solicitor.
That said, you should strongly consider legal advice if:

  • You own property or significant assets outside the UK.
  • You have business assets, complex shareholdings, or partnership arrangements.
  • You want to set up a trust or protect a vulnerable beneficiary.
  • You expect a dispute (for example, a blended family situation or strained relationships).
  • You are trying to exclude a spouse, civil partner or child from inheriting.

If you’re unsure whether your situation is suitable for a simple will, you can
contact us with a quick question before starting.

7. Quick FAQs

Do I need a solicitor to make a valid will in Scotland?

Not always. For many people with a straightforward estate, a simple will is enough — provided it is worded
appropriately for Scots law and signed correctly.

Does a Scottish will need to be registered to be valid?

No. Registration is optional. The key is that the original signed will exists and can be found when needed.

What is the most common reason wills fail in practice?

Signing and witnessing mistakes. People often get the wording right, then rush the final step.

Can I change my will later?

Yes. Most people review their will after major life events such as marriage, separation, a new child,
or buying a home.
