No, not necessarily no, there is actually no onus to to do so.
Now the Law stipulates that if you do make an unsolicited recording that ends up as evidential in a trial, then the admissibility of it is up the the Judge. However, unless there is a good reason for the prosecution to claim otherwise, then Courts do tend to side with the defence, so the likelihood is that any such recording would be admissible as part of the case.
