|As someone who works for the court system, I would say itís helpful when the notary clearly identifies himself by name, commission number and expiration date, and then identifies the person before them before administering the oath. |
Once the oath is administered, there is no need for the notary to stick around. The oath stands.
Now I canít say for sure about the deposition question, because in Florida the only requirement is for the notary to administer the oath.
