Frequently Asked Questions

Everything you need to know.

Are e-signatures legally valid in the UK?

Yes. The Electronic Communications Act 2000 (ECA 2000) provides the legal framework for e-signatures in the UK. UK eIDAS (the EU eIDAS Regulation as retained in UK law) recognises three tiers: Simple Electronic Signature (SES), Advanced Electronic Signature (AES), and Qualified Electronic Signature (QES). Zignature provides SES and AES — valid for the vast majority of UK commercial documents.

Does Zignature comply with UK GDPR?

Yes. Zignature processes personal data in accordance with UK GDPR requirements and can provide a UK GDPR data processing agreement. Data can be stored in EU or UK infrastructure as required by your data residency requirements.

Can UK employment contracts be signed electronically?

Yes. Employment contracts — including the written statement of particulars required by the Employment Rights Act 1996 — can be executed electronically. Zignature's UK employment contract templates include all required statutory provisions.

Are there UK documents that cannot be signed electronically?

Most commercial and employment documents can be signed electronically. Some documents require wet-ink signatures, a deed format, or witnessing — wills, land registration transfers (TR1), and certain regulated financial products. Consult a solicitor for specific document types.

Does Zignature support Qualified Electronic Signatures (QES) for UK regulated documents?

Zignature integrates with eIDEasy for Qualified Electronic Signatures meeting UK eIDAS QES requirements — the highest UK signature standard. QES requires a qualified trust service provider and identity verification.

Is Zignature's UK GDPR data processing compliant for UK businesses?

Yes. Zignature can execute a UK GDPR Data Processing Agreement as required under Article 28 UK GDPR. Zignature acts as a data processor when processing personal data on behalf of your business.
