How to update Savings Bond registrations

My husband was co-owner on my Savings Bonds. He has passed away. How do I get the beneficiary changed? Tom's response When a registrant listed on a Savings Bond dies, the surviving registrant can have the registration updated by submitting one of the following forms. The forms include complete instructions. For Series I Savings Bonds, use Public Debt Form 5387. For all other Savings Bonds, use Public Debt Form 4000. If for some reason you can't print these out online, you can also order paper copies of the forms. Click here to visit the premier independent web site for owners of United States Saving Bonds.
