Witness Signature
A third party signs to confirm they watched you sign.
What it means
A witness signature is the signature of a third party who watched a document being signed and signs to confirm it. Most everyday contracts do not require witnesses, but some document types — wills in most states, certain deeds and powers of attorney — do, and who may serve as a witness varies by state. A witness confirms the act of signing; unlike a notary, a witness usually holds no official commission and has no duty to verify identity.
Why it matters before you sign
If the document type calls for witnesses, the wrong number of witnesses — or a witness with a stake in the document — can undermine it, so check the requirements before signing day.
In a contract, it looks like this
The power of attorney was signed in front of two witnesses, each of whom signed and printed their name below the signature block.
