Yeah, well I don't know either. I'm just making this up. But there have to be contracts involved. I remember hearing about an instance years ago where a surrogate didn't want to hand over the baby to the biological parents after carrying it for 9 months, and the courts getting involved. As a result of that, there have got to be legal contracts now. And any halfway decent lawyer who draws up such a contract has got to predict the possibility of a desired abortion.
Don't make me go googling this stuff.
