Who can Witness an Attorneys Signature on an LPA?

27th February 2026

Who can Witness an Attorneys Signature on an LPA? Valid LPA witness rules explained is one of the most important questions you can ask when setting up a lasting power of attorney.

The signing stage often looks simple, but small mistakes can cause real problems. If the witness does not meet the legal requirements, the Office of the Public Guardian may reject the application.

That can mean delays, extra paperwork and paying the registration fee again.

Understanding who can witness an attorney’s signature helps make sure your LPA is accepted first time.

What is the role of a witness in an LPA?

A witness confirms that a signature was made properly.

Their role is to be present when the person signs and to verify that the signature is genuine.

In a lasting power of attorney, several signatures need to be witnessed. This includes the donor and the attorneys.

The rules for each role are slightly different, which is why confusion often happens.

Getting the details right matters because the Office of the Public Guardian checks the forms carefully during registration.

Who can witness an attorney’s signature?

The rules for witnessing an attorney’s signature are fairly straightforward.

The witness must be aged 18 or over and must be present when the attorney signs the LPA.

They also need to have mental capacity and be able to confirm they saw the signature take place.

In most cases, this can be a friend, neighbour, colleague or another independent adult.

The key requirement is that the witness is physically present at the moment the attorney signs.

Remote witnessing is not permitted.

Can another attorney act as the witness?

Yes, another attorney named in the same LPA can witness the signature of a fellow attorney.

This is allowed as long as the witness meets the standard legal requirements.

For example, if two attorneys are appointed, one may witness the other’s signature.

However, an attorney cannot witness the donor’s signature.

Keeping those roles separate is an important rule within the LPA signing process.

Who cannot witness an attorney’s signature?

While the rules are flexible, there are still some situations to avoid.

A witness should not be someone who is unable to understand what they are witnessing or someone who is not physically present during the signing.

The witness must see the attorney sign the document in person.

If the witness signs later or was not present at the time, the LPA could be rejected.

Why witnessing mistakes can cause LPA rejection

Many lasting power of attorney applications are rejected every year because of errors in the signing process.

Common issues include signatures completed in the wrong order, witnesses not being present or incorrect witness details.

Even small mistakes can mean the forms must be corrected or resubmitted.

This can delay registration by several weeks or months.

That is why taking care during the signing stage is so important.

How to choose a suitable witness

Choosing a suitable witness is usually straightforward.

Look for someone who is over 18, independent and available to watch the signature in person.

Friends, neighbours and colleagues are often suitable choices.

The most important thing is that the witness understands their role and is present when the attorney signs the form.

Getting the LPA signing process right

Witnessing an attorney’s signature on a lasting power of attorney is not complicated, but the rules must be followed carefully.

Ensuring the witness is eligible, present and independent helps prevent avoidable mistakes.

When the signing process is handled correctly, the LPA is far more likely to be accepted by the Office of the Public Guardian without delays.
