Sec. 3-94j. Official notarial seal.
(a) A notary public, except a state police major, captain, lieutenant or sergeant appointed as a notary public pursuant to section 3-94e, may keep and use an official notarial seal. Such seal shall not be used by any other person or surrendered to any employer upon termination of the notary's employment.

Sec. 3-94k. Notarial certificate. Notarial seal. Stamp.
If a notary public utilizes a notarial seal, the notary shall, near the notary's official signature on a notarial certificate, affix an impression of the notarial seal, which shall include:
(1) The notary's name exactly as it appears on the notary's certificate of appointment,
(2) the words “Notary Public” and “Connecticut” and
(3) the words “My commission expires (commission expiration date)”,
provided the notary may elect to have the words in subdivision (3) appear on a stamp instead of such seal. If the notary does not utilize a notarial seal or stamp, the words “Notary Public” and “My commission expires (commission expiration date)” shall be typed or printed legibly by the notary near the notary's official signature on a notarial certificate.

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.
