Client care and engagement letters
Engagement and client care letters are signed in minutes via a secure link. The advanced signature (AES) records the client, the scope of the retainer and the time of signing, avoiding later disputes over fees.
Settlement agreements
Settlement agreements are generally form-free and can be signed with AES or QES. The eIDAS evidence report serves as an exhibit if validity is later challenged. (Statutory settlement agreements under ERA 1996, s. 203 additionally require the conditions and independent legal advice to be met.)
Powers of attorney and NDAs in bulk
Send powers of attorney and non-disclosure agreements in bulk with configurable reminders. Each signature is captured with a timestamp and IP in the audit trail, admissible as evidence.

Linked to the signer with an SMS OTP and an audit trail. Recommended standard for most contracts.
Qualified (QES)
The legal equivalent of a handwritten signature, with qualified certificate, for the most sensitive documents.
Recommended level for this sector
Law firms get the highest assurance: the qualified signature (QES) carries the strongest evidence of identity and integrity under UK eIDAS. Deeds still require a physically present witness.
British legal framework
Deeds require a witness who is physically present
Where a document is executed as a deed, the Law Commission (2019) confirms the witness must be physically present when the signatory signs — even where both use electronic signatures (Law of Property (Miscellaneous Provisions) Act 1989, s. 1). Certyneo flags deeds in the workflow so the witnessing requirement is met.
Evidential weight of electronic signatures
Electronic signatures are admissible as evidence and the qualified signature (QES) under UK eIDAS carries the highest assurance of identity and integrity. The audit trail of Certyneo (timestamp, IP, OTP) supports the evidential position in a dispute.
