“A woman was inseminated with Aiken’s semen. She gave birth to their child. Aiken has custody. Because she’s the non-custodial parent, she has to pay child support.”
Any guy who donates semen or a woman who acts as a surrogate should have an iron-clad agreement that they can’t be sued for child support. And even then they’re nuts for doing it.
Courts are knocking down the “iron-clad agreements” as being inimical to the best interest of the child. The only smart (as well as only right) choice is just not to do it.
