In plain English
Witnesses are different from notaries. A document may need witnesses, a notary or both. The requirements come from the document type and local law.

A notary generally should not be an interested party.
Why it matters
Some documents need witnesses in addition to a notary, and arriving without them can stop a signing that took weeks to arrange. Wills and certain health care forms are common examples.
Who can serve as a witness matters too. A witness with a stake in the document may cause problems later when the document is relied on.
Worked example
A will is signed by the testator with two witnesses watching; a notary may also complete a self-proving affidavit.
What to do
- Ask the office or attorney that prepared the document how many witnesses are needed and who qualifies.
- Arrange witnesses with valid ID who have no interest in the document.
- Make sure witnesses watch the actual signature, not just sign afterward.
- Have witnesses print and sign their names where the form indicates.
- Do not assume the notary can also serve as a witness; ask first.
Common mistakes
- Using a family member named in the document as a witness can lead to questions about the document later.
- Having witnesses sign after the signer leaves fails because they must see the signature made.
- Showing up with one witness when the form needs two can halt the appointment.
Not the same as: Credible witness
A subscribing witness observes and signs a document, while a credible witness only vouches for the signer's identity to the notary. See Credible witness.
