A Power of Attorney is a legal document that grants someone the authority to make decisions on behalf of another person. In the United Kingdom, this can cover decisions about property, finances, or health and welfare. However, for the power of attorney to be legally valid, proper witnessing of the document is essential.

The Importance of Power of Attorney Witnessing

Power of Attorney Witnessing serves as a safeguard to ensure the authenticity of the Power of Attorney. It confirms that the person granting the power—known as the donor—signed the document voluntarily, with full understanding of its contents and implications. A witness helps prevent fraud, coercion, or undue influence by verifying the donor's identity and mental capacity at the time of signing.

Without a properly witnessed power of attorney, the document may be rejected by relevant institutions or legal bodies, delaying vital decisions or leaving the donor vulnerable during a time of need.

Legal Requirements for Witnessing

In the United Kingdom, witnessing rules vary slightly depending on the type of Power of Attorney.

Ordinary Power of Attorney - This applies when someone wants to give temporary authority over their affairs. The donor’s signature must be witnessed by an independent adult who is not one of the attorneys.

Lasting Power of Attorney - This type is more complex and is split into two categories—property and financial affairs, and health and welfare. The donor must sign the Lasting power of attorney in the presence of a witness. In addition, a certificate provider must confirm that the donor understands the document and is not under pressure to sign it.

Enduring Power of Attorney - Though no longer available for new registrations, existing enduing power of attorney must still be witnessed and follow set procedures to remain valid.

When is Witnessing Required?

Witnessing is required at the point of signing by the donor, and separately by each attorney. Each signature must be witnessed in real time by someone physically present—remote witnessing is not accepted under UK law. Failing to meet these conditions can result in the document being invalidated.

In short, proper witnessing of a Power of Attorney is not a formality. It is a legal necessity that ensures protection, clarity, and peace of mind for everyone involved.
