Affidavit of Service: What It Must Say and How to Get It Witnessed
An affidavit of service proves a document was delivered. What it must say, who can witness it, and how to get it sworn by video call.

Electronic signatures do not all carry the same legal weight. A typed name is enough for many everyday agreements, but a contract that may be relied on abroad, or a document issued in a company's name, often needs a stronger form of signature. StatDec Hub offers four services, described below, and the table at the end matches common situations to each one.
UK and EU law (eIDAS and the UK Electronic Communications Act 2000) recognise three levels of electronic signature, each giving more legal assurance than the one before.
A simple electronic signature (SES) is a typed name, a scanned signature or a tick box. It is widely used but gives the lowest level of assurance. StatDec Hub does not offer it.
An advanced electronic signature (AES) is uniquely linked to the signatory and can detect later changes to the document. It is stronger than a simple signature but below the qualified level.
A qualified electronic signature (QES) is the highest level under eIDAS. It is created using a qualified certificate issued by a trust service provider and is treated as equivalent to a handwritten signature in the UK and EU. It is FCDO approved.
Organisations can also use a qualified electronic seal (eSeal), which authenticates a document on behalf of a legal entity rather than an individual.
The Enhanced Electronic Signature meets the requirements of the UK Electronic Communications Act 2000 and eIDAS. It is valid in the UK and EU and is FCDO approved.
It is suitable for:
This combines a QES with written certification from a UK-qualified solicitor, which makes it acceptable to more institutions and jurisdictions than a signature alone.
It is suitable for:
A QES is not suitable for a will. Under the Wills Act 1837, a will made in England and Wales must be signed physically by the person making it in front of two witnesses.
The eSeal is the organisational equivalent of a QES. It confirms that a document was issued by a specific legal entity and has not been altered since it was sealed. It is valid in the UK and EU and is FCDO approved.
It is suitable for:
Where the signature or seal alone is not enough, our solicitors can advise on the document's content, effect or enforceability alongside the QES or eSeal. Valid in the UK and EU.
It is suitable for:
| Situation | Service |
|---|---|
| Standard UK contract | Enhanced Electronic Signature |
| Cross-border agreement or regulatory submission | QES with solicitor certification |
| Document issued on behalf of a company | Qualified Electronic Seal |
| Signature plus legal review | QES or eSeal with legal advice |
