Do Witnesses Need to Read My Will?

Section 9 of the Wills Act 1837 requires that the testator sign the will, or acknowledge an existing signature, in the presence of two witnesses present together at the same time, and that each witness then sign the will themselves, in the presence of the testator. The focus throughout is on the act of signing, not on the content of the document being signed.

This means a witness's job is essentially to be a reliable, independent observer of a specific event: the signing. They confirm, by their own signature, that this event took place as described, which is important evidence if the will's validity is ever questioned after the testator's death.

Because their role is procedural rather than substantive, there is no legal requirement for witnesses to read, understand, or agree with what the will says. You can fold the document so that only the signature page is visible, or otherwise keep its contents private, and this does not affect the validity of the witnessing in any way.

Many people prefer to keep the contents of their will confidential, even from the witnesses, particularly if the will deals with sensitive family matters, specific sums of money, or arrangements they would rather not discuss openly. This is entirely your choice and does not undermine the legal effectiveness of the signing.

While witnesses do not need to read the will's contents, they should pay attention to the testator's apparent state of mind and behaviour during the signing. If a witness later needs to give evidence about the signing, for example if the will is challenged on grounds of capacity or undue influence, their observations about how the testator appeared and acted can matter a great deal, even though they never read the document itself.

Witnesses should be satisfied, from what they can observe, that the testator appears to understand they are signing their will and appears to be acting freely, without visible signs of pressure, confusion or distress. This is a common-sense observation, not a formal legal assessment, but it is a genuinely useful part of what witnesses contribute.

Most wills include an attestation clause near the signature page, a short statement confirming that the testator signed in the presence of both witnesses, who then signed in the testator's presence. This clause helps demonstrate later that the correct process was followed, without needing to say anything about the will's substantive content.

This is one reason a well-drafted attestation clause is valuable: it provides a clear, contemporaneous record of proper execution, addressing exactly the questions that might arise later, while leaving the private contents of the will entirely separate from what the witnesses are confirming.

If you prefer to keep your will private, simply let your witnesses know in advance that they are there to witness the signature, not to read the document, and most people find this entirely unremarkable. There is no need to explain or justify keeping the contents confidential.

Make sure both witnesses are genuinely present together, watching the actual signing (or your acknowledgement of an existing signature), and that they then sign themselves while you watch, since this sequence matters far more to validity than anything to do with the will's contents.
