At First Law Solicitors, we provide professional witnessing and certification services for the signing of Powers of Attorney and personal or corporate guarantees. Our role is to verify identity, witness the signing of the document and confirm proper execution in accordance with UK legal requirements. We act as independent witnesses only and do not provide advice on the terms or legal effect of the documents unless you specifically request separate legal advice.
A Power of Attorney allows a person, known as the donor, to appoint another individual or organisation, known as the attorney, to act on their behalf in legal or financial matters. When executed correctly, it gives the attorney authority to sign documents, manage property or handle transactions in the donor’s name.
A personal or corporate guarantee is a formal promise to take responsibility for another person’s or company’s financial obligation if they fail to meet it. Banks, lenders and other institutions commonly require a solicitor to witness the signing of these documents in order to confirm the identity of the signatory and that the document has been signed voluntarily.
Our solicitors ensure that each Power of Attorney or guarantee document is signed and witnessed in line with UK legal formalities and any additional requirements imposed by the relevant lender or institution.
When you attend your appointment, our solicitor will verify your identity by checking an original passport, driving licence or another accepted form of identification. We will confirm that you are signing the document voluntarily and understand that it is a legally binding instrument. The solicitor will then witness your signature and complete the required certificate or attestation so that the document can be accepted by the lender, institution or receiving authority without delay.
This witnessing service applies to both Powers of Attorney and guarantee documents and is designed to ensure that execution is completed correctly the first time. If you require legal advice on the content or implications of the document, we can arrange a separate independent legal advice appointment.
Since 2025, digital signing and remote witnessing have been available under the Digital Verification Services framework, where accepted by the receiving authority. Our solicitors can witness and certify the signing of Powers of Attorney and guarantee documents through secure video appointments, using Qualified Electronic Signatures to complete the process.
This option is particularly useful for clients who are based overseas or unable to attend our offices in person. All digital witnessing and certification is recorded, securely stored and fully traceable, ensuring that documents remain valid under UK evidentiary standards.
All client information and documents are handled with strict confidentiality. Records are managed and stored in accordance with UK GDPR and the Data (Use and Access) Act 2025, under the supervision of the Information Commission, formerly the ICO. Original documents are returned immediately after signing, and certified records are stored securely within encrypted systems to preserve authenticity and traceability.
At First Law Solicitors, we make the document signing process clear, compliant and efficient. Our solicitors are experienced in handling formal execution of Powers of Attorney, loan and finance guarantees, property documents and commercial agreements.
We offer flexible appointments, including remote digital witnessing, and provide clear confirmation that your document has been correctly signed and certified. Our aim is to ensure that your paperwork meets the exact requirements of banks, lenders and other institutions, avoiding delay or rejection.
