United Kingdom 中的 Construction 使用案例
Building contracts (JCT, NEC)
Building contracts not executed as deeds are form-free and signed with AES in minutes. Employer and contractor sign via a link; the audit trail records identity and time, key for limitation periods and defects liability.
Variations and valuations in bulk
Variations on scope changes are sent in bulk with configurable reminders (day 3 / day 7). The eIDAS evidence report shows agreement to the additional sum if a dispute arises over the variation.
Practical completion certificates on mobile
Practical completion triggers limitation and the release of retention. With Certyneo the completion certificate is signed on site from a tablet; snags, time and parties are recorded with integrity.

Simple building contracts are form-free — the advanced signature (AES) offers the best balance of evidence and speed for mobile use on site. Deeds require a physically present witness.
British法律框架
Form-free contracts vs. deeds and collateral warranties
A simple building contract has no form requirement and can be signed electronically. However, where a contract is executed as a deed (e.g. many collateral warranties, to obtain a 12-year limitation period), the witness must be physically present (Law Commission 2019). Certyneo flags deeds in the workflow.
Evidential weight (UK eIDAS)
Electronic signatures are admissible as evidence; the audit trail of Certyneo (timestamp, IP, OTP) supports proof of the time of signing and of agreement to variations — decisive for payment and defects disputes.

常見問題 — Construction United Kingdom
Are electronically signed building contracts valid in the UK?
Yes. A simple building contract has no form requirement and can be signed entirely electronically. The advanced signature (AES) of Certyneo evidences identity, time and integrity and is admissible as evidence.
Can a collateral warranty be signed electronically?
If executed as a deed (common, to secure a 12-year limitation period), the witness must be physically present when the signatory signs (Law Commission 2019). Certyneo flags deeds; warranties executed as simple contracts can be signed without that constraint.
Does a mobile-signed completion certificate have evidential weight?
Yes. The electronically signed certificate is captured with a timestamp, IP and OTP in the audit trail. These support the completion time and recorded snags — decisive for limitation periods and the release of retention.
