Answer:
Your institution should have on hand a copy of the Treasury's Guide to Cashing Savings Bonds. The last section of the Guide includes a series of questions you should follow to ensure that you have the appropriate documentation for handling this sort of transaction. If you are sure that you have all the required documents, plus the EIN assigned to the estate (you cannot accept the SSN of the decedent or the estate representative), have the executor or administrator sign his or her name with the annotation of his/her representative capacity (for example, Ex. U/W of Mary Jones, Dec'd).
