Notaries Public are "commissioned" (i.e., licensed) by the Secretary of State. Notarial functions include:
administering oaths and affirmations;
taking affidavits and depositions;
receiving and certifying acknowledgments or proof of such written instruments as deeds, mortgages and powers of attorney; and;
demanding acceptance or payment of foreign and inland bills of exchange, promissory notes and obligations in writing, and protesting the same for non-payment
Many banks, law offices and other institutions which deal in financial or real property transactions employ individuals who are commissioned as Notaries Public.
