Can you sign a power of attorney online in the UK?

TL;DR: A lasting power of attorney in England and Wales still cannot be signed digitally, according to Youtrust, while a general or commercial power of attorney can be executed electronically if deed formalities, witness presence, or corporate signing rules are followed. The dividing line is not convenience but whether the document can satisfy the legal safeguards that make later reliance defensible.

Editorial analysis by NHI Mgmt Group, based on content published by Youtrust: “Power of Attorney: How to Sign One Electronically in the UK”.

Key questions

Q: When should organisations use electronic signing for powers of attorney?

A: Use electronic signing only where the legal form allows it and the witnessing or execution rules can still be satisfied.

Q: Why do lasting powers of attorney still require hand signing?

A: LPAs still require hand signing because the law treats them as high-assurance instruments that depend on a single original document, attestation, and registration before use.

Q: What should teams do when a delegated authority document may be challenged?

A: Preserve the signed original, witness details, signing order, and any registration evidence, then verify whether the instrument was valid at the time it was used.

Practitioner guidance

• Specify the correct POA execution path Separate lasting powers of attorney from general or commercial POAs before selecting the signing method, because the legal execution rules are different and cannot be treated as interchangeable.
• Preserve the witness and attestation chain Require physical witness presence for deeds that need it, and document the signing order, witness details, and final attestation so the execution record survives later challenge.
• Build revocation and expiry checks into authority workflows Track when a POA ends, is revoked, or becomes invalid through death, divorce, bankruptcy, or loss of capacity, and make downstream teams verify status before relying on it.

Bottom line: The article’s central point is that electronic signing is not uniformly available for powers of attorney, because the signing rule depends on the document type and the legal assurance it must provide.
