This can be done during the initial stages, while setting up the account (ie before submission)- either by your lawyer or by you, see: HOWTO: SEF Account setup to allow your lawyer AND you to access the account. I have direct access, as well as my lawyer. Set up by my lawyer (whom I have known for a very long time).
However, thus far I have not seen a single post where access was obtained after the initial set-up/submission. In theory, this should be possible because, over the 5-year period, lawyers can be changed, and there has to be a way to hand-over from one set of lawyers to the next.
