Signer Terms
Code Four Sign Signer Terms
What you agree to when you adopt a signature and sign a document electronically with Code Four Sign. Written to be read in a few minutes, before you sign.
Version 1 — September 11, 2026
How the service meets the ESIGN Act and UETA — intent, consent, association, retention and integrity — and what it records about you is set out on the compliance page.
1. Who these terms are for
You are reading these terms because someone sent you a document to sign through Code Four Sign, at sign.codefour.us. These terms are between you and Code Four, the operator of the service, and they cover how the electronic signature works.
Code Four is not a party to the document you are signing. The document, its terms and the relationship it describes are between you and the sender. By using the link you were sent, you agree to complete this transaction electronically with the sender, and to be bound by the terms of the document you sign in the same way you would be bound by a paper copy you signed by hand.
2. Confirm the sender
The signing link is a credential. Anyone with access to the mailbox it was sent to can open it. Before you sign, make sure you know who sent the document and that you expected it; the sender's name and email address are shown at the top of the signing page and in the email that carried the link.
Some senders add a one-time emailed code or an access code they gave you separately. Those gates exist so that only you can complete the signature, and they are recorded with it. If you did not expect the document, do not sign it; you can decline from the signing page and the sender is told.
3. Signing on behalf of an organization
If you sign as a representative of a company, an agency or another organization, your signature may bind that organization. Only sign in that capacity if you are authorized to do so.
4. The document is frozen at send
When the sender sends a document for signature, Code Four Sign takes a snapshot of it: the exact file bytes, every field and its placement, every recipient, and the consent statement you are shown. Nothing in that snapshot can change afterwards. What you see while signing is what everyone signs, and the completed document and its certificate refer back to that snapshot by its cryptographic hash.
If the document needs to change, the sender has to void the request and send a new one. Ask the sender to do that rather than signing something you know is incomplete or wrong.
5. Documents that may not be eligible
Electronic signatures are widely recognized, but some documents are excluded from electronic signature laws or carry extra requirements in many places. Wills and codicils, trusts, powers of attorney, real property deeds and certain family-law and court documents are common examples. If you are not sure whether the document in front of you can be signed electronically where you are, ask the sender or consult a lawyer before signing.
6. Your copies
Once every signer has finished, Code Four Sign emails each signer a link to the completed document and to its completion certificate. Code Four keeps the completed document, the certificate and the evidence package that supports them for the retention period the sender's organization has agreed with Code Four. Download and keep your own copy; do not rely on the emailed link alone.
Anyone holding a copy of the completed document can check that it is the sealed original at sign.codefour.us/verify, without an account and without asking Code Four. The check compares the file's hash with the completion manifest that was cryptographically sealed when the document was completed.
7. Where the signature is enforceable
Whether an electronic signature is enforceable depends on the law that applies to the document and to the parties, and that varies by country, state and document type. Code Four Sign is designed to meet the requirements of the U.S. ESIGN Act and UETA, including a clear record of intent, consent to sign electronically, association of the signature with the record, and retention. If the parties or the document are outside the United States, or you are unsure, consult a lawyer.
8. What is recorded about you
Signing produces evidence. The completion certificate and the audit trail record the name and email address of every party, the network (IP) address and device (browser) each action came from, the time of each action in the document's time zone, and whether an emailed code or access code was used. This information is part of the executed document's record, and anyone who has the completed document or its certificate can read it, including the sender and the other signers.
Your drawn signature is stored as its shape only. How quickly you drew it is not kept.
9. What Code Four does not promise
Nothing on this page or in the signing flow is legal advice. Code Four does not review the documents sent through the service, does not know your situation, and does not guarantee that a signature will be enforceable in any particular jurisdiction or for any particular document. If you have questions about what you are signing or whether you should sign it, ask the sender or a lawyer.
Versions
Version 1 — September 11, 2026 is the current version. The consent statement you accept at signing carries its own version, which is recorded on your consent event together with a hash of the exact text you were shown, so the statement you agreed to can always be identified.
