If not by Lolo Soetoro, then by his Grandparents in 1970 when Barack Sr. Came to visit coincidentally at the same time Stanley Ann was visiting from Indonesia. A few signatures, and Voilà! Stanley has the "Son" he always wanted. He certainly shows affection for the boy in that beach photo.
I have personally witnessed a signing over of custody before. It was all over in a couple of days.
