I have sessioned with a number of highly regarded professional Dommmes over the years. I have never been asked for any kind of official ID in order to schedule session.

If asked, I would not be comfortable providing it in advance of a session. My biggest concern is what happens with the information after the session ? How secure is the Domme's computer ? If she has a problem with LE, would it somehow be accessible to them ? Would anyone besides the Domme have access to the ID info ?

A lot can go very badly wrong, and it may not even be the Dommes fault. There are so many very high highly skilled Dommes that will session with references and deposits that it seems to me to be an unnecessary risk.
