(2) the words “Notary Public” and “Connecticut” and

State of Connecticut Notary Public Manual
4.18 Notary Public Journals
Connecticut state law does not require that notaries maintain a journal of their notarial acts. However, it is the very strong recommendation of the Office of the Secretary of the State that they do so. The journal is a record of the notarial acts performed and could be vital in protecting the notary from possible liability. The journal should be a bound book to prevent loss or substitution of pages, and the notary should record the following information for each transaction:
1. the date and time of the notarial act;
2. the nature or type of notarial act performed;
3. a description of the document or proceeding;
4. the signature, printed name and address of each person for whom a notarial act is performed;
5. the method by which a person's identity has been determined;
6. the fee, if any is charged; and
7. the place where the notarial act was performed.
