Well he can try. He should not be able to get the info he seeks, and there are probably violations of various things, but he certain "can" give it a go. The old therapist may choose (for various ethical and legal reasons) not to comply with his attempts without Lola's consent, or she could overlook the reasons not to do so and talk to him. It certainly is a breach of many different tenets, but there are those who care not for such. I would run from anyone who tried, regardless of their ultimate success. However. I took his statement as reported as though he was asking Lola if she would be okay with him doing it - not that he would do it without her consent.
