You do not necessarily need to go to Court if you both agree. Perhaps you can just enter a Stipulation and Order indicating that both parents agree to permit you full legal custody for so long as dad is living outside of the United States. This document would need to be filed with the Court, but neither of you would need to appear. In California, custody - including legal custody - is modifiable until the child is 18, so you can change things as necessary during that time and certainly this seems like one of those times.
