Which action must a notary take after obtaining a new bond rider?

When a notary obtains a new bond rider, the correct action is to return the old bond policy rider. This is important because the bond rider is an amendment to the notary's bond that provides additional coverage or modifies existing terms. Returning the old rider ensures that there is no confusion over which bond is currently in effect and helps maintain accurate records. It is essential for compliance with state laws and regulations regarding notary bonds, which stipulate that there can only be one bond in effect for a notary at any given time.

The other actions, while potentially relevant in different contexts, are not mandatory steps following the receipt of a new bond rider. Notifying clients of the change, submitting a new application, or acquiring a new seal does not directly relate to the process of updating or changing a bond rider, making them less relevant in this scenario.
