The Primary Beneficiary is the first person or entity you want to receive the proceeds of your accounts. There can be more than one primary beneficiary.
For example:
Primary Beneficiary: 50% to John Doe, son and 50% to Jane Doe, daughter.
The secondary beneficiary is the second person or entity you want to receive the proceeds of your accounts should the primary be deceased or not meet specific serviceable qualifications you have instructed. There can be more than one secondary beneficiary just as the example above appears.
