Who changed the lawyer after submitting the application?

The application has been submitted and is pending. At this stage, I want to change my lawyer. What’s the procedure here? Has anyone done this?

If you have your own access (login/pass) to the SEF portal, then you can change the email of your legal rep any time, as far as I understand. So it should be simply a matter of finding your new lawyer and re-typing their email instead of the ‘terminated’ one.
If you don’t have your own access, then it’s tough. You are probably stuck with your current lawyer unless they agree to offload your profile somehow over to you, but I don’t know how this can be done if at all.
