A notary commission is personal. It is granted to an individual on the basis of that individual's oath, bond and background check, and every act performed under it is that person's own act with their own liability attached. The seal is the physical embodiment of that personal authority, so California treats it as the exclusive property of the notary regardless of who paid for it. An employer that bought the seal has bought an object it cannot lawfully use, because a seal in anyone else's hands is a fraud instrument — it can make documents appear authenticated by a notary who never saw them. The same logic governs the journal, which is also the notary's property and goes with them, subject to the delivery obligations that apply when a commission ends. The employer's remedy for its expense, if any, is a matter of agreement between the parties, and it does not change who owns the seal. On leaving, the notary takes both.
