What happens if a Will is unsigned?

3 March 2026

Have you ever thought about what happens to an estate if the deceased only leaves behind a Will that was never signed?

This can sometimes happen when the document was rushed shortly before death or it was drafted years earlier and never finalised.

Some people assume that just writing down their wishes is enough, but unfortunately, that is not how the law works in England and Wales.

Unless a Will is signed and witnessed in the correct way, it has no automatic legal effect.

What are the requirements of a valid Will?

The rules governing execution are set out in section 9 of the Wills Act 1837.

For a Will to be valid, it must meet the following requirements:

• The Will must be in writing.
• It must be signed by the person making the Will or by someone else in their presence and at their directive.
• The signature must be made or acknowledged in the presence of two witnesses simultaneously.
• Each witness must then sign the Will or acknowledge their signature in the presence of the testator.

Failure to comply with any one of these steps renders the document invalid, no matter how clearly it sets out the deceased’s wishes.

Can the Court ever uphold an unsigned Will?

If a Will has not been properly executed in accordance with the requirements we listed above, the Court has no power to treat it as valid.

It is not the Court’s responsibility to correct mistakes or supply missing formalities.

That said, there are limited circumstances in which the contents of an unsigned Will may still be relevant, even though the document itself is not legally binding.

What can be done if the Will is unsigned?

There are typically three options loved ones of the deceased can try, where a Will may still be used to make arrangements after the individual’s death.

These include Inheritance Act claims, deeds of variation and professional negligence claims, where appropriate.

Under the Inheritance Act 1975, certain people can apply to the Court for reasonable financial provision from an estate.

When considering such a claim, the Court may look at evidence of the deceased’s intentions.

An unsigned Will can sometimes form part of that evidence, especially where it supports a claim by a spouse, civil partner or dependent.

The document does not become a Will, but it may influence the level or structure of any award.

If the deceased failed to leave a valid Will, the estate passes under the intestacy rules. Those entitled under intestacy can agree between themselves to redirect the estate by entering into a deed of variation.

Where all beneficiaries agree, the terms of an unsigned Will can be adopted voluntarily through this route. However, this requires full consent and proper legal drafting.

If a solicitor drafted the Will but failed to ensure it was executed before the testator’s death, beneficiaries may have a claim against the solicitor for professional negligence.

The claim can help them obtain compensation for financial losses caused by the failure to complete the Will properly, but it will not validate the Will.
