OA or No?

Hi, so just a genuine question lang naman..So OA ba na tawag if yung partner mo ang emergency contact nya is yung ex pa nia sa driver's license niya..2023renewed his license, 2022 kami na..not even his family member or any of them ang contact..so if something happened to him ang ccontact nila is yung ex not even the family members muna or me?
