Several of us did it in 2021.
SEF is now AIMA, but the information to submit is the same.
It can be done either (1) by asking someone you trust to help (ideally your lawyer as lawyers have special privileges in relation to AIMA), and add your email access as the main applicant while you set up the application (see SEF ARI Portal - Did you register yourself or just let lawyer handle this? ), OR (2) by the applicant setting up the application and adding the lawyers’ contacts (HOWTO: SEF Account setup to allow your lawyer AND you to access the account ).
In both cases, everything is visible to the applicant and lawyer, and the applicant gets an email from SEF for appointments, payments etc.
But joint access can only be set up before the GV application is made.
Make sure that you have the bona fide originals of what you submit online. You will need to provide the originals to AIMA later. Every document that is submitted to AIMA as a period of validity (e.g. 3 months for criminal background, 6 months for marriage certificate). So keep track of periods of validity after you submit as you will need valid certificates at biometrics (whenever that occurs). The initial submission does not require the apostilled police records, but you will need them later.
If you do not speak/write in Portuguese, I advise getting a lawyer. Begin to use the search function as there are several recommendations of lawyers used by others.
