You can overcall 1NT or 2NT with a small singleton. But you can never, ever open 1NT with a small single- ton…or even singleton jack or 10. And, if you do choose to open 1NT with a singleton other than ace, king or queen, it may become a disciplinary matter subjecting you to a procedural penalty or perhaps worse.
