In the U.S. state of Florida, a notary public is a public officer appointed by the governor of the state to take acknowledgments, administer oaths, attest to photocopies of certain documents, solemnize marriage, protest the non-acceptance or non-payment of negotiable instruments , and perform other duties specified by law. A notary may only perform a notarial act upon receipt of satisfactory proof of identity (i.e. a driver's license or other form of identification card), or by the notary's own personal knowledge of the person appearing before them, or upon the sworn statement of two witnesses who personally know the person whose signature is to be authenticated. A notary may not notarize their own signature, or the signature of their spouse, parent, or child. Authority of a Florida notary public Notaries public in Florida have the authority to take acknowledgments, administer oaths, solemnize marriage, certify the contents of a safe-deposit box, certify the vehicle identification number of a motor vehicle, and certify copies of documents which are not public records. Acknowledgments are usually taken in correlation with a real estate transaction, but are often used in cases where a mere "identity verification" is needed to ensure that the document is being executed by an authorized party. Oaths are administered orally in depositions and court hearings in which a party is being sworn in over the telephone instead of being personally present before a judge. In this respect, notaries administer oaths in the same way as a judge. Many court reporters are also notaries, as this allows one person to both swear the party in for a deposition and to transcribe the deposition. Oaths are also administered in the form of affidavits and other sworn statements on paper. Marriages may be legally solemnized by a notary public between parties who present the notary with a valid marriage license. The law has no requirements for the form of a marriage ceremony, therefore many notaries perform both civil and religious marriage ceremonies. The contents of a safe-deposit box are certified by a notary public in cases where the owner has died or otherwise abandoned the safe-deposit box. In this case, the notary must be present while a bank official and other witness open the box. The notary then certifies the contents of the box and makes a certificate thereof for presentation to the court or to the personal representative of the Decedent's estate. Notaries
