A simpler way to agree
The paperwork moves.
Your day moves on.
From a multi-page tenancy agreement to a client contract, keep the next step simple for everyone.
Start with your document.
Send ChatSign a PDF, or photos of each page. Photos are straightened, cleaned up and combined into one tidy PDF.
Send it in the chat.
Sign it yourself, or send it to anyone's WhatsApp number. They get a secure link that opens on their phone.
They open. Review. Sign.
The recipient reads the agreement, adds their signature with a finger, and both of you get the signed PDF back in WhatsApp. No printing or scanning back.
On the record
Signed today.
Still solid later.
Every signed document comes with the evidence you'd want if anyone ever asks.
Signature certificate
A final page records who signed, when, from which IP address, and the document's unique fingerprint.
Tamper-evident trail
Sent, opened and signed are time-stamped, and each step is chained to the last so records can't be quietly edited.
Encrypted storage
Documents are encrypted before they're stored in London. Signing links are single-use and expire after 72 hours.
For the people

Questions.
What is ChatSign?
ChatSign gets documents signed through WhatsApp. Send it a PDF or photos of a paper document, choose who signs, and everyone gets the signed copy back in the chat.
Does the recipient sign inside WhatsApp?
They tap a secure link in WhatsApp, which opens the document in their phone's browser. They read it, sign with a finger, and the signed PDF comes back to WhatsApp.
Will signers need to download an app?
No. Signers just need WhatsApp and a phone browser. No app, no account, no password.
Is it just for one-page documents?
No. Multi-page PDFs work, up to 10 pages on Free and 200 on Pro. You can also photograph each page of a paper document and ChatSign combines them.
Is an e-signature legally binding in the UK?
For most everyday documents, such as tenancy agreements, contracts, consent forms and quotes, yes. UK law (including the Electronic Communications Act 2000 and UK eIDAS) recognises electronic signatures. Some documents have special rules, such as wills, certain deeds that need a witness, and some property and court documents. ChatSign doesn't give legal advice; if you're unsure, check with a solicitor.
Where is my data stored?
Documents are encrypted before they're stored, in London. See the privacy policy for how long we keep things and how to ask us to delete them.
