Get agreements signed without the other side creating an account.

Asking someone to create an account just to sign one agreement slows everything down. OfClause lets you invite the other side through a guest link, so they can open the agreement, review it and sign it in their browser.

How the guest link works

When an agreement is ready, you invite the other party by email. They receive a personal link. Opening it takes them straight to the document — there is no sign-up form and no password to create.

  1. Prepare the agreement in OfClause and check the terms.
  2. Invite the other party using their email address.
  3. They open the link and review the agreement in their browser.
  4. They sign. For NDAs, the email they sign with must match the person the NDA was sent to.
  5. Both sides can see that the agreement has been signed.

Staying in control of access

Guest links are time-limited. When you invite someone, the link is set to expire after a set period, such as 7 or 30 days. You can revoke a guest's access at any time, or revoke all guest access to a conversation at once.

Guests only see what they were invited to. They do not get access to the rest of your account, your other agreements or your contacts.

What the signer sees

The signer sees the agreement title, the document itself and a signature step. If the document has already been signed, the link shows that instead of asking for a second signature. If a link is no longer valid or has expired, the signer sees a clear message rather than the document.

What OfClause records when someone signs

When an NDA is signed, OfClause stores the signature together with the time of signing, the IP address the request came from and the browser's user agent. It also generates a SHA-256 verification hash from the signature, timestamp, IP address and document reference, which helps show the stored signing record has not been altered.

When a guest signs an agreement from a conversation, OfClause records the time of signing and the IP address.

These records are evidence of how and when a document was signed. They are not identity verification: OfClause does not check passports or other ID. If you need stronger proof of who signed, agree that separately.

When guest signing is a good fit

Guest signing suits everyday business agreements: a freelancer and a client, a supplier and a small business, two companies sharing information under an NDA. For deeds, property transactions, or agreements with specific formality or witnessing requirements, take advice from a solicitor on how they must be signed.

Pairing guest signing with the rest of OfClause

Guest signing works at the end of the flow: you can turn a WhatsApp chat or email thread into an agreement record, or agree the deal in OfClause Messenger, then send it for signature with a guest link. You can also create a free NDA draft and sign up to send it.

Frequently asked questions

How long does a guest link last?
Guest links expire after a set period chosen when the invitation is sent, such as 7 or 30 days. You can also revoke access at any time.
What is recorded when an NDA is signed?
The signature, the time of signing, the IP address, the browser user agent and a SHA-256 verification hash of the signing record.
