A therapist will either see you as an individual client or see you and your partner together for couples therapy. This is decided after the initial assessment is done, so that the right service can be recommended. That being said, if you are in individual therapy, it may be beneficial to have a couple of joint sessions with your partner. Of course this will only be done at the behest of the primary client and is not required. When having a joint session in individual therapy, the focus will still be on the primary client and how the partner can support them in their growth or assisting the client share information with their partner.
