In "Ted Williams: The Biography of an American Hero", author Leigh Montville claims that the family cryonics pact was a practice Ted Williams autograph on a plain piece of paper, around which the agreement had later been hand written. The pact document was signed ""Ted Williams"", the same as his autographs, whereas he would always sign his legal documents ""Theodore Williams"", according to Montville. However, Claudia testified to the authenticity of the document in an affidavit. Ted's two 24-hour private caregivers who were with him the entire period the note was said to have been created also stated in affidavits that John-Henry and Claudia were never present at any time for the note to be produced.
