How to witness a signature online
Some documents need a witness, and the question of whether that witness can be remote is one of the few in electronic signing where the answer genuinely differs by country and by document. This page covers how to add a witness in practice, what the record has to capture, and where to stop and check before relying on it, because a deed witnessed the wrong way is not a small problem.

How to witness a signature online, step by step
- Add the signer and the witness as separate parties, The witness is a signer with their own fields and their own record, not a name typed into a box by somebody else.
- Set the order, The witness signs after the party they are witnessing, because that is what witnessing means: they attest to having seen it happen.
- Capture the witness details, Name, address and capacity, in text fields on the document itself, which is what most attestation clauses require.
- Verify the witness identity if it matters, OTP or ID verification on the witness, so the attestation is connected to a person rather than to an email address.
- Keep the audit certificate, It records the sequence: when each party opened, signed and was verified, which is the evidence that the witnessing was in the right order.
What you get
- The witness gets their own fields and their own audit record instead of a typed name.
- Sequential signing enforces the order that makes an attestation meaningful.
- Identity checks can be required on the witness, not just the signer.
- The certificate shows the timeline, which is what a challenge to witnessing actually turns on.
- Works on a phone, which matters when a witness has to be found at short notice.
Frequently asked questions
How do I witness a signature online?
Add the witness as their own signer, set the order so they sign after the party they are witnessing, and give them fields for their name, address and capacity. Whether a remote witness is accepted depends on the document type and the jurisdiction, so check that first.
Can a witness sign a document electronically?
In many jurisdictions yes, for many document types, and the position has moved a long way since 2020. But deeds, wills, powers of attorney and some property documents often carry specific requirements about physical presence. Check the rule for that document type in that jurisdiction before you rely on remote witnessing.
Does the witness have to be physically present?
That is exactly the question the law answers differently in different places. Some jurisdictions require presence, some allow video presence, some have no requirement at all for ordinary contracts. It is not something a signing tool can decide for you.
Who can act as a witness?
Usually an adult who is not a party to the document and has no interest in it. Some documents exclude family members. The attestation clause in the document itself often says.
What should the witness record?
Full name, address and often occupation, plus the date. That is what an attestation clause typically asks for, and it is why the witness needs their own text fields rather than a signature alone.
What PDF Verified is, and what it is not
Electronic signature law is settled in broad terms and specific in the details. The ESIGN Act, UETA, eIDAS and their equivalents recognise electronic signatures across more than 190 countries, and what decides a particular case is intent to sign plus evidence connecting the signature to the signer, which is what the audit certificate records. Certain document types carry their own formalities wherever you are: deeds, wills, some property instruments, and anything requiring a witness or a notary. Sign only what you are authorised to sign, since applying another person signature without their authority is forgery whatever tool is used.
PDF Verified is a tool for preparing, signing, stamping and checking documents. It is not a law firm, a compliance service or a forensic examiner, and nothing here is legal, financial or compliance advice. Requirements differ by country, by document type and by the party asking, so check what applies to your document before you rely on it, and take advice where the document matters. You are responsible for the documents you create, sign and send, and for having the authority to do so: signing or stamping in somebody else name, or as an organisation you do not represent, is forgery whatever tool is used. To the extent the law allows, we accept no liability for how a document made with this tool is used or relied on. The full position is in our terms of service.
