I moved to Spain last year and my parents who are spaniards (no US citizens and/or residents) authorized me on their accounts (signatory authority but not ownership of the accounts). I know that I am required to file the FBAR, not only for my accounts but also for the ones that I'm authorized (theirs).
My doubt is about for the form 8938. Do I need to file it with my taxes? I don't reach the threshold requirements with my foreign accounts; however, with my parents' , I do!
