Can I let another TreasuryDirect account holder see or cash my converted bonds?
In TreasuryDirect you can grant View and Transact rights. If the security is registered in your name alone, you can grant, and revoke at will, View rights to another TreasuryDirect account owner. A security registered to you as owner with a beneficiary allows you to grant, and revoke at will, View rights to the designated beneficiary only. However, if it is a Series E security with a beneficiary, you can only grant View rights to the designated beneficiary, and once granted, you can’t revoke the rights. Similarly, you can grant View and Transact rights to the co-owner of a converted bond, but once granted, you can’t revoke these rights. Co-owner registration securities with granted View rights may be edited to grant Transact rights but not from Transact to View. View and Transact rights are not available in entity accounts.
