Although the omission of 'to' was formerly possible in English, it is now considered nonstandard. Usages such as  that are common in many varieties of American English. The phrase 'ought not to' is preferred to 'He hadn't ought to come' (He ought not to come) and 'She shouldn't ought to say' (She ought not to say). See more Usage notes.
