What Are The Witness Requirements?

If any document(s) to be notarized require a witness be present at the time of signing, it is the Signer's responsibility to facilitate the presence of a witness. 

Witnesses must have valid identification with them. 

Wills 
Florida requires that at least two (2) witnesses be present at the signing of a will, and that they be present when the Testator signs the will, and that they sign the will as witnesses. The Notary cannot act as a witness on a Self-proving Affidavit for a will, as it is improper for a Notary to notarize his/her own signature. 

Power of Attorney
Florida requires that at least two (2) disinterested Witnesses be present at the signing of a Power of Attorney. The Notary can act as a witness as well as notarize the signature.
