Here is a stretch...you can google Obama Sr divorce papers. It comes up on the first page.
FYI, divorces can happen by publication, and many happen if the father cannot be found....
The papers clearly indicate he signed for them when served, but apparently did not reply. Thus he was known to have been served, and had a chance to respond, but did not. Lolo, OTOH, did sign his papers, but he wished to remarry. So did BHO Sr, but he waited until he got back to Kenya to marry his second "white" woman, where polygamy is legal anyway. She divorced his ashes too, and married another African man, but not a Kenyan, again IIRC.
