By legally stating that Barry was still recieving help with his education and that Maya was the only minor child, the document clearly indicates that:
1. Barry is not a minor child, hence an adult (19yo)
2. Barry was adopted, hence part of the divorce proceedings to show his educational support.
So, it also ties in with his travels to Pakistan in 1980-81 which makes him 19-21 years old, which shows he was traveling with an Indonesian passport IMO.
It seems clear to me that a child can have two legal fathers in two different countries just as they can have two legal citizenships.
Stanley Ann may have made a purely tangential reference to Barry in her Soetoro divorce just to dispose of any child support issue. She is also suspected of using the “truth” opportunistically as the Soetoro may have done when declaring Obama to be his son and an Indonesian citizen to get him into school (and Muslin).
We have no forensic legal evidence of any adoption in Indonesia or HI and lack of an index for an adoption for Barry in HI. We have no passport evidence for Barry for the US, Kenya or Indonesia and claims that US citizens couldn't travel to Pakistan in 1981 have been definitively refuted by contemporary travel packages in the NY Times (from memory).
We just don't know and can only guess how Barry got to Pakistan and whether he could travel there on a non-US passport obtained without renouncing his US citizen or NBC status (if he ever had citizen or NBC status).
At least the extremely important confirmation of an HI record of an index for the Stanley-Obama Sr marriage was made last week.
