Short answer: set by your state
Retention is set by state law and rules vary widely. Check your own state notary handbook or commissioning office.
How long to keep records
Retention periods vary by state. Some states specify a number of years, while others have different rules. Ask your state notary commissioning office or check your handbook for the requirements that apply to you.
Who owns your journal
Rules vary by state. Ask your state notary commissioning office whether the journal is your exclusive property and whether an employer can require you to hand it over.
