Legitimacy, Illegitimacy, Primogeniture

The wife of Abraham was unable to reproduce their offspring for sometime after their marriage. Obviously in order to produce their offspring Abraham let another woman have his child with his wife's consent. The first child between another woman and Abraham was Ishmael.
Later his wife had a baby with Abraham. His name is Isac.
Bioloically speaking Ishmael is the first son and Isac is the second, under the primogeniture Ishmael had to succeed all the fortunes and wealth, land, etc. of Abraham. But the reality was different. Because Isac was a son born protected under the legal system -marriage where the meaning of legitimacy comes from, Isac was loved by his father and Ishmeal was not regarded as important as his younger brother -Isac, later Ishimael was kicked out of their house.
My question is marriage on paper as a form of legal registration should be prior to the biological reproduction held before the outcome from the legal liason appeared.
