LPA Signing Mistakes — Errors That Will Get Your LPA Rejected

Common Mistakes7 min read14 April 2026

Quick Answer

The most common LPA signing mistakes are signing in the wrong order, using ineligible witnesses, missing signatures, and dating errors. The correct order is: donor signs first, then certificate provider, then attorneys and replacement attorneys. Each signature must be witnessed.

Key Facts

  • The correct signing order is: donor, certificate provider, then attorneys (in any order).
  • Every signature must be witnessed by an independent person aged 18 or over.
  • The donor's witness cannot be one of the attorneys.
  • Signing out of order will invalidate the LPA.
  • All signatures must be dated, and dates must be consistent with the correct order.
  • Using correction fluid (Tippex) on signatures can cause rejection.
  • A separate person can witness each signature — they do not all need the same witness.

Why do signing mistakes matter?

Signing is the most critical stage of creating a Lasting Power of Attorney. The OPG is strict about signing requirements because signatures are what give the LPA its legal force. A single signing error can invalidate the entire document, requiring you to start over and pay another £92 registration fee.

What is the correct LPA signing order?

The LPA must be signed in this exact order:

  • Step 1: The donor signs — Section 9 of the LPA. A witness must sign immediately after the donor.
  • Step 2: The certificate provider signs — Section 10. This must happen on the same day as or after the donor's signature, never before.
  • Step 3: Each attorney signs — Section 11. Each attorney signs separately, with their own witness. This must happen on the same day as or after the certificate provider's signature.
  • Step 4: Each replacement attorney signs — Also Section 11. Same rules as for attorneys.

The dates on each signature must reflect this order. If the certificate provider's date is before the donor's date, the LPA will be rejected.

What are the most common signing mistakes?

Signing out of order

This is the single most common signing error. People often gather everyone together and sign at the same time without paying attention to the required order. Even if everyone signs on the same day, the order matters.

Missing witness signatures

Every signature on the LPA must be witnessed. Forgetting to have a witness sign, or forgetting to have the witness provide their full name and address, will cause rejection.

Using an ineligible witness

The donor's witness cannot be any of the attorneys named in the LPA. Anyone else aged 18 or over can be the donor's witness. Each attorney needs their own witness — this can be the donor, another attorney, or any other adult.

Date errors

Dates must be consistent with the signing order. Common date errors include:

  • The certificate provider's date being earlier than the donor's date.
  • An attorney's date being earlier than the certificate provider's date.
  • No date being written at all.
  • Using American date format (month/day/year) instead of UK format (day/month/year).

Using correction fluid

If you make a mistake, do not use correction fluid (Tippex). Instead, cross out the error with a single line, write the correction, and have all relevant parties initial the change. Heavy corrections or the use of correction fluid can lead to rejection.

Signing the wrong section

Each person must sign in their designated section. The donor signs Section 9, the certificate provider signs Section 10, and attorneys sign Section 11. Signing in the wrong section will cause problems.

Can everyone sign on the same day?

Yes, as long as they sign in the correct order. Having everyone available on the same day is often the most convenient approach — just make sure the donor signs first, followed by the certificate provider, followed by the attorneys.

What if an attorney lives far away?

Attorneys do not need to be physically present when the donor signs. They can sign their section later (but not before the certificate provider). You can post the LPA to remote attorneys for signing, as long as the dates reflect the correct order.

Frequently Asked Questions

What is the correct LPA signing order?

The donor signs first (Section 9), then the certificate provider (Section 10), then each attorney and replacement attorney (Section 11). Each signature must be witnessed.

Can the donor and certificate provider sign on the same day?

Yes, as long as the donor signs before the certificate provider. They can even be in the same room — the donor just needs to sign their section first.

Who can witness the donor's signature?

Anyone aged 18 or over who is not an attorney or replacement attorney named in the LPA. This can be a friend, family member, neighbour, or colleague.

Can the same person witness all the signatures?

One person can witness multiple signatures, provided they are eligible for each. However, the donor's witness cannot be an attorney, while an attorney's witness can be the donor or another attorney.

What if I make a mistake while signing?

Cross out the error with a single line, write the correction, and have all relevant parties initial the change. Do not use correction fluid. For major errors, you may need to reprint the affected page.

Does the LPA need to be signed in ink?

Yes. The LPA must be signed with a pen in ink. Digital or electronic signatures are not accepted. Black ink is recommended as it copies most clearly.
