I think it wouldn't hurt to ask the t if she'd mind being taped. If you explained why the way you explained it here, maybe she'd understand and want to do it to help you worry less.

I don't know if what somebody posted, saying that listening to the recordings could make you anxious, could be true, but you could work that out if it happened.

I've read on here about people recording their sessions because they tend to have trouble remembering them, so it's not that unusual. A lot of people are really uncomfortable being recorded, but other people aren't. It doesn't usually bother me. I don't know why. So I think it doesn't hurt to find out how your t feels about it.

I wonder if it would make your t more anxious because you're a lawyer, and you would have evidence if they make a mistake. If your t is nervous about it, you could offer to leave the recordings with her and only go back and check them together during sessions.

It is unusual to be so focused on getting the facts right that you need to record something. But maybe it would help and it doesn't hurt to ask.
